Binary XML file line#0: error inflating class android.widget.imageview

Question

after searching for a solution for 3 hours without finding a solution I decided to fo for Ask Question. So I am using BaseAdapter to populate gridview with images and the error is on the line where I inflate the layout in getView() method of BaseAdapter

adapter.java

public class adapter extends BaseAdapter {
Context context;
int images[];
LayoutInflater inflater;
public adapter(final Context applicationcontext, final int[] images)
{
    this.context=applicationcontext;
    this.images=images;
    inflater=(LayoutInflater.from(applicationcontext));
}

@Override
public int getCount() {
    return images.length;
}

@Override
public Object getItem(int position) {
    return null;
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(int position, View view, ViewGroup parent) {
    try{
        view =inflater.inflate(R.layout.images_list, null);// error line
        ImageView imageView=(ImageView) view.findViewById(R.id.icon);
        imageView.setImageResource(images[position]);

    }
    catch (Exception ex)
    {
        ex.printStackTrace();
    }
    return view;
}

}

here is my xml

images_list.xml

<?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"
    android:padding="1dp"
    android:orientation="vertical">
    <ImageView
        android:id="@+id/icon"
        android:layout_width="match_parent"
        android:layout_height="120dp"
        android:scaleType="fitXY"
        android:layout_gravity="center_horizontal"
        android:src="@drawable/ic_launcher_foreground" />

</LinearLayout>

*its exception causes to crash app.* then post it whole ... I bet that: you made type and ImageView is written like imageview ... as you have `Binary XML file line#0: error inflating class android.widget.imageview` in the title and class `android.widget.imageview` doersn't exists — Selvin, Jan 15 '18 at 12:26
**this stacktrave is useles ... the real error is before this** ... inflate throws some exception and view is null thats why you have this NPE — Selvin, Jan 15 '18 at 14:03

Replace below line

view =inflater.inflate(R.layout.images_list, null);

with

view =inflater.inflate(R.layout.images_list, parent, false);

what error this would fix and how? there is method `LayoutInflater.inflate(int, android.view.ViewGroup)` ... while using `inflate(int resource, ViewGroup root, boolean attachToRoot)` is better that will not fix "error" (unless he has only warning - but in the questrion is **error**) – Selvin Jan 15 '18 at 12:20
@Selvin The parent is provided so you can inflate your view into that for proper layout parameters. The parent parameter of the getView() method gives a reference to the parent layout which has the listView – Poras Bhardwaj Jan 15 '18 at 12:23
I know what it does but how this will fix **an error** which he is asked about ... – Selvin Jan 15 '18 at 12:24
He is passing null instead of parent view while inflating the view. He should pass rootView/parent – Poras Bhardwaj Jan 15 '18 at 12:27
*He is passing null instead of parent view while inflating the view. He should pass rootView/parent* **This not causing an error ... it is only bad for performance!** ... again, yes, it is good to use `inflate(int resource, ViewGroup root, boolean attachToRoot)` but **it will not fix his error** – Selvin Jan 15 '18 at 12:28
replacing the code did not work as you suggested – Zain Arshad Jan 15 '18 at 12:32
@Selvin So, please let us know the cause of error & help Zain Arshad out. – Poras Bhardwaj Jan 15 '18 at 12:34
