What I am trying to do: I am trying to make a custom dialog in android With rounded corners.

What is happening: I am able to make custom dialog but it doesn't have rounded corners. I tried adding a selector but still I couldn't achieve rounded corners.

Below is my code for the same:


Java code:

private void launchDismissDlg() {

        dialog = new Dialog(getActivity(), android.R.style.Theme_Dialog);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.dlg_dismiss);
        dialog.setCanceledOnTouchOutside(true);

        Button btnReopenId = (Button) dialog.findViewById(R.id.btnReopenId);
        Button btnCancelId = (Button) dialog.findViewById(R.id.btnCancelId);

        btnReopenId.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {



            }
        });


        btnCancelId.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {



            }
        });
        dialog.setCanceledOnTouchOutside(false);
        dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
        dialog.getWindow().setLayout(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
        dialog.show();

    }

xml code:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

Create a xml in drawable , say dialog_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid
        android:color="@color/white"/>
    <corners
        android:radius="30dp" />
    <padding
        android:left="10dp"
        android:top="10dp"
        android:right="10dp"
        android:bottom="10dp" />
</shape>

set it as the background in your layout xml

android:background="@drawable/dialog_bg"

Set the background of the dialog's root view to transparent, because Android puts your dialog layout within a root view that hides the corners in your custom layout.

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

You need to do the following:

  • Create a background with rounded corners for the Dialog's background:

    <?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
    
        <solid android:color="#fff" />
    
        <corners
            android:bottomLeftRadius="8dp"
            android:bottomRightRadius="8dp"
            android:topLeftRadius="8dp"
            android:topRightRadius="8dp" />
    
    </shape>
    
  • Now in your Dialog's XML file in the root layout use that background with required margin:

    android:layout_marginLeft="20dip"
    android:layout_marginRight="20dip"
    android:background="@drawable/dialog_background"
    
  • finally in the java part you need to do this:

    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(layoutResId);
    View v = getWindow().getDecorView();
    v.setBackgroundResource(android.R.color.transparent);
    

This works perfectly for me.

    if you want to use same value for all corners then you should use `` , otherwise you'll get rendering issues – Mehran Aug 25 '18 at 05:51

    @Mehran good point. Thanks for pointing that out. Can you also share the source of this info? – SMR Aug 29 '18 at 05:53
  • @SMR `Path.isConvex is not supported` this is the warning you usually get in your layout if you use a shape with same value for all corners. https://stackoverflow.com/q/34736981/6605907 – Mehran Aug 29 '18 at 07:48

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

this works for me

With the Androidx library and Material Components Theme you can override the getTheme() method:

import androidx.fragment.app.DialogFragment

class RoundedDialog: DialogFragment() {

    override fun getTheme() = R.style.RoundedCornersDialog

    //....

}

with:

<style name="RoundedCornersDialog" parent="@style/Theme.MaterialComponents.Dialog">
    <item name="dialogCornerRadius">16dp</item>
</style>

Or you can use the MaterialAlertDialogBuilder included in the Material Components Library:

import androidx.fragment.app.DialogFragment
import com.google.android.material.dialog.MaterialAlertDialogBuilder

class RoundedAlertDialog : DialogFragment() {

    //...

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        return MaterialAlertDialogBuilder(requireActivity(), R.style.MaterialAlertDialog_rounded)
                .setTitle("Test")
                .setMessage("Message")
                .setPositiveButton("OK", null)
                .create()
    }

}

with:

<style name="MaterialAlertDialog_rounded" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
    <item name="shapeAppearanceOverlay">@style/DialogCorners</item>
</style>

<style name="DialogCorners">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">16dp</item>
</style>

enter image description here

If you don't need a DialogFragment just use the MaterialAlertDialogBuilder.

If you use Material Components:

CustomDialog.kt

class CustomDialog: DialogFragment() {

    override fun getTheme() = R.style.RoundedCornersDialog

}

styles.xml

<style name="RoundedCornersDialog" parent="Theme.MaterialComponents.Dialog">
    <item name="dialogCornerRadius">dimen</item>
</style>

    It was the solution for me, thanks! In my case, I added text and background color: – fvaldivia Nov 26 '19 at 09:34

I made a new way without having a background drawable is that make it have CardView as parent and give it a app:cardCornerRadius="20dp" and then add this in the java class dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

It's another way to make it .

Setting

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

will prevent dialog to cast a shadow.

Solution is to use

dialog.getWindow().setBackgroundDrawableResource(R.drawable.dialog_rounded_background);

where is R.drawable.dialog_rounded_background

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <shape android:shape="rectangle" android:padding="10dp">
            <solid
                android:color="@color/dialog_bg_color"/>
            <corners
                android:radius="30dp" />
        </shape>
    </item>

</layer-list>

You can use the shape for the background as-

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="@android:color/transparent"/>
<corners android:radius="10dp" />
<padding android:left="10dp" android:right="10dp"/>
</shape>

Have a look on this for the details.

You can simply use MaterialAlertDialogBuilder to create custom dialog with rounded corners.

First create a style for the material dialog like this :

<style name="MyRounded.MaterialComponents.MaterialAlertDialog" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
    <item name="shapeAppearanceOverlay">@style/ShapeAppearanceOverlay.App.CustomDialog.Rounded
    </item>
    <item name="colorSurface">@color/YOUR_COLOR</item>
</style>

<style name="ShapeAppearanceOverlay.App.CustomDialog.Rounded" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">10dp</item>
</style>

then create a Alert Dialog object in Java class like this :

AlertDialog alertDialog =  new MaterialAlertDialogBuilder(this,R.style.MyRounded_MaterialComponents_MaterialAlertDialog)  // for fragment you can use getActivity() instead of this 
                    .setView(R.layout.custom_layout) // custom layout is here 
                    .show();

            final EditText editText = alertDialog.findViewById(R.id.custom_layout_text);   // access to text view of custom layout         
            Button btn = alertDialog.findViewById(R.id.custom_layout_btn);

            btn.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    Log.d(TAG, "onClick: " + editText.getText().toString());
                }
            });

That's all you need to do.

simplest way is to use from

CardView and its card:cardCornerRadius

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView 
 xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:card="http://schemas.android.com/apk/res-auto"
 android:orientation="vertical"
 android:id="@+id/cardlist_item"
 android:layout_width="match_parent"
 android:layout_height="130dp"
 card:cardCornerRadius="40dp"
 android:layout_marginLeft="8dp"
 android:layout_marginRight="8dp"
 android:layout_marginTop="5dp"
 android:layout_marginBottom="5dp"
 android:background="@color/white">

  <RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="12sp"
    android:orientation="vertical"
    android:weightSum="1">
    </RelativeLayout>

</android.support.v7.widget.CardView>

And when you are creating your Dialog

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

For anyone who like do things in XML, specially in case where you are using Navigation architecture component actions in order to navigate to dialogs

You can use:

<style name="DialogStyle" parent="ThemeOverlay.MaterialComponents.Dialog.Alert">

    <!-- dialog_background is drawable shape with corner radius -->
    <item name="android:background">@drawable/dialog_background</item>

    <item name="android:windowBackground">@android:color/transparent</item>
</style>

Here is the complete solution if you want to control the corner radius of the dialog and preserve elevation shadow

Dialog:

class OptionsDialog: DialogFragment() {

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup, savedInstanceState: Bundle?): View {
    dialog?.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
    return inflater.inflate(R.layout.dialog_options, container)
}

}

dialog_options.xml layout:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

<androidx.cardview.widget.CardView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="40dp"
    app:cardElevation="20dp"
    app:cardCornerRadius="12dp">

    <androidx.constraintlayout.widget.ConstraintLayout
        id="@+id/actual_content_goes_here"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
    </androidx.constraintlayout.widget.ConstraintLayout>

</androidx.cardview.widget.CardView>
</FrameLayout>

The key is to wrap the CardView with another ViewGroup (here FrameLayout) and set margins to create space for the elevation shadow.

For API level >= 28 available attribute android:dialogCornerRadius . To support previous API versions need use

<style name="RoundedDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
        <item name="android:windowBackground">@drawable/dialog_bg</item>
    </style>

where dialog_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item >
        <shape >

In Kotlin, I am using a class DoubleButtonDialog.Java with line window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT)) as important one

class DoubleButtonDialog(context: Context) : Dialog(context, R.style.DialogTheme) {

    private var cancelableDialog: Boolean = true
    private var titleDialog: String? = null
    private var messageDialog: String? = null
    private var leftButtonDialog: String = "Yes"
    //    private var rightButtonDialog: String? = null
    private var onClickListenerDialog: OnClickListener? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
        //requestWindowFeature(android.view.Window.FEATURE_NO_TITLE)
        setCancelable(cancelableDialog)
        setContentView(R.layout.dialog_double_button)
//        val btnNegative = findViewById<Button>(R.id.btnNegative)
//        btnNegative.visibility = View.GONE
//        if (rightButtonDialog != null) {
//            btnNegative.visibility = View.VISIBLE
//            btnNegative.text = rightButtonDialog
//            btnNegative.setOnClickListener {
//                dismiss()
//                onClickListenerDialog?.onClickCancel()
//            }
//        }
        val btnPositive = findViewById<Button>(R.id.btnPositive)
        btnPositive.text = leftButtonDialog
        btnPositive.setOnClickListener {
            onClickListenerDialog?.onClick()
            dismiss()
        }
        (findViewById<TextView>(R.id.title)).text = titleDialog
        (findViewById<TextView>(R.id.message)).text = messageDialog
        super.onCreate(savedInstanceState)
    }

    constructor(
        context: Context, cancelableDialog: Boolean, titleDialog: String?,
        messageDialog: String, leftButtonDialog: String, /*rightButtonDialog: String?,*/
        onClickListenerDialog: OnClickListener
    ) : this(context) {
        this.cancelableDialog = cancelableDialog
        this.titleDialog = titleDialog
        this.messageDialog = messageDialog
        this.leftButtonDialog = leftButtonDialog
//        this.rightButtonDialog = rightButtonDialog
        this.onClickListenerDialog = onClickListenerDialog
    }
}


interface OnClickListener {
    //    fun onClickCancel()
    fun onClick()
}

In layout, we can create a dialog_double_button.xml

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="@dimen/dimen_10"
        android:background="@drawable/bg_double_button"
        android:orientation="vertical"
        android:padding="@dimen/dimen_5">

        <TextView
            android:id="@+id/title"
            style="@style/TextViewStyle"
            android:layout_gravity="center_horizontal"
            android:layout_margin="@dimen/dimen_10"
            android:fontFamily="@font/campton_semi_bold"
            android:textColor="@color/red_dark4"
            android:textSize="@dimen/text_size_24"
            tools:text="@string/dial" />

        <TextView
            android:id="@+id/message"
            style="@style/TextViewStyle"
            android:layout_gravity="center_horizontal"
            android:layout_margin="@dimen/dimen_10"
            android:gravity="center"
            android:textColor="@color/semi_gray_2"
            tools:text="@string/diling_police_number" />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="@dimen/dimen_10"
            android:gravity="center"
        android:orientation="horizontal"
        android:padding="@dimen/dimen_5">

        <!--<Button
            android:id="@+id/btnNegative"
            style="@style/ButtonStyle"
            android:layout_width="0dp"
            android:layout_height="@dimen/dimen_40"
            android:layout_marginEnd="@dimen/dimen_10"
            android:layout_weight=".4"
            android:text="@string/cancel" />-->

        <Button
            android:id="@+id/btnPositive"
            style="@style/ButtonStyle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:backgroundTint="@color/red_dark4"
            android:fontFamily="@font/campton_semi_bold"
            android:padding="@dimen/dimen_10"
            android:text="@string/proceed"
            android:textAllCaps="false"
            android:textColor="@color/white"
            android:textSize="@dimen/text_size_20" />
    </LinearLayout>
</LinearLayout>

then use drawable.xml as

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid
        android:color="@color/white"/>
    <corners
        android:radius="@dimen/dimen_10" />
    <padding
        android:left="@dimen/dimen_10"
        android:top="@dimen/dimen_10"
        android:right="@dimen/dimen_10"
        android:bottom="@dimen/dimen_10" />
</shape>

Create a xml in drawable ,say customd.xml.

then set it at background in your custom Dialog layout xml:

android:background="@drawable/customd"

finally in the java part for custom Dialog class you need to do this:

public class Customdialoque extends DialogFragment {

public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

    View view = inflater.inflate(R.layout.activity_customdialoque, container, false);

    return view;
}

I implemented rounded dialog using CardView in the custom layout and setting its corner radius.

Here's my xml code.

<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/bottomSheet"
android:layout_width="match_parent"
android:layout_margin="@dimen/padding_5dp"
app:cardCornerRadius="@dimen/dimen_20dp"
android:layout_height="wrap_content">

<androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/main_gradient_bg"
    android:paddingBottom="32dp">

    <TextView
        android:id="@+id/subdomain_label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="@dimen/margin_32dp"
        android:layout_marginLeft="@dimen/margin_32dp"
        android:layout_marginTop="@dimen/margin_50dp"
        android:fontFamily="@font/nunito_sans"
        android:text="@string/enter_subdomain"
        android:textColor="@color/white"
        android:textSize="@dimen/size_18sp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent" />


    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="@dimen/dimen_45dp"
        app:layout_constraintLeft_toRightOf="@id/subdomain_label"
        app:layout_constraintTop_toTopOf="parent"
        app:srcCompat="@drawable/ic_baseline_info_24" />

    <EditText
        android:id="@+id/subdomain_edit_text_bottom_sheet"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginStart="@dimen/dimen_20dp"
        android:layout_marginLeft="@dimen/dimen_20dp"
        android:layout_marginEnd="@dimen/dimen_20dp"
        android:layout_marginRight="@dimen/dimen_20dp"
        android:textColor="@color/white"
        android:theme="@style/EditTextTheme"
        app:layout_constraintTop_toBottomOf="@id/subdomain_label" />

    <Button
        android:id="@+id/proceed_btn"
        android:layout_width="@dimen/dimen_150dp"
        android:layout_height="@dimen/margin_50dp"
        android:layout_marginTop="@dimen/margin_30dp"
        android:background="@drawable/primary_btn_bg"
        android:text="@string/proceed"
        android:textAllCaps="false"
        android:textColor="@color/white"
        android:textSize="@dimen/size_18sp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="@id/subdomain_edit_text_bottom_sheet" />
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.cardview.widget.CardView>

After that, i called it in Kotlin as follows :-

    val builder = AlertDialog.Builder(mContext)
    val viewGroup: ViewGroup = findViewById(android.R.id.content)
    val dialogView: View = 
    LayoutInflater.from(mContext).inflate(R.layout.subdomain_bottom_sheet, 
    viewGroup, false)
    val alertDialog: AlertDialog = builder.create()
    alertDialog.setView(dialogView,0,0,0,0)
    alertDialog.show()
    val windowParam = WindowManager.LayoutParams()
    windowParam.copyFrom(alertDialog.window!!.attributes)
    windowParam.width = AppConstant.getDisplayMetricsWidth(mContext) - 100
    windowParam.height = WindowManager.LayoutParams.WRAP_CONTENT
    windowParam.gravity = Gravity.CENTER
    alertDialog.window!!.attributes = windowParam
    
   
    alertDialog.window!!.setBackgroundDrawable
    (ColorDrawable(Color.TRANSPARENT))

Where last line is very important. Missing that would cause a color(mostly white) to show behind the corners.

Here is a Basic Solution:

 <style name="Style_Dialog_Rounded_Corner" parent="Theme.AppCompat.Light.Dialog.Alert">
        <item name="android:windowBackground">@drawable/dialog_rounded_corner</item>
        <item name="android:windowMinWidthMinor">85%</item>
    </style>

in Drawable create shape:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FFFFFF" />
    <corners android:radius="12dp" />
</shape>

Pass style in Builder Constructor

AlertDialog alert = new AlertDialog.Builder(MainActivity.this,R.style.Style_Dialog_Rounded_Corner).create();
