Question

I wanna create a customized ListView like this:

TextView+ImageView in ListView

I think that I have to use BaseAdapter but I have no idea about it.

You have to use ViewHolder for performance...check this http://stackoverflow.com/questions/19469073/how-do-you-efficiently-load-bitmaps-from-drawable-folder-into-a-listview/19469076#19469076 — Vrajesh, Jul 31 '14 at 08:43
@ShaktisinhJadeja the layout inflater comes from the activity class since the adapter was implemented inside of it. Try - LayoutInflater.from(context) if it's a stand alone class. — Lin, Jul 26 '16 at 12:58

public class ListElementAdapter extends BaseAdapter{

    String[] data;
    Context context;
    LayoutInflater layoutInflater;


    public ListElementAdapter(String[] data, Context context) {
        super();
        this.data = data;
        this.context = context;
        layoutInflater = LayoutInflater.from(context);
    }

    @Override

        return data.length;
    }

    @Override

    @Override

    @Override

        convertView= layoutInflater.inflate(R.layout.item, null);

        TextView txt=(TextView)convertView.findViewById(R.id.text);

        txt.setText(data[position]);



        return convertView;
    }
}

Just call ListElementAdapter in your Main Activity and set Adapter to ListView.

how can I use it ? ListElementAdapter adapter = new ListElementAdapter(array, this); will not work as it extends BaseAdapter and BaseAdapter is an abstract class — eawedat, Feb 02 '18 at 19:45
As the answer is too old and ListView is deprecated in Android. I would suggest you - Use Recycler View instead. Thanks — Ganesh Katikar, Feb 05 '18 at 10:08

Create your own BaseAdapter class and use it as following.

 public class NotificationScreen extends Activity
{

@Override
protected void onCreate_Impl(Bundle savedInstanceState)
{
    setContentView(R.layout.notification_screen);

    ListView notificationList = (ListView) findViewById(R.id.notification_list);
    NotiFicationListAdapter notiFicationListAdapter = new NotiFicationListAdapter();
    notificationList.setAdapter(notiFicationListAdapter);

    homeButton = (Button) findViewById(R.id.home_button);

}

}

Make your own BaseAdapter class and its separate xml file.

public class NotiFicationListAdapter  extends BaseAdapter
{
private ArrayList<HashMap<String, String>> data;
private LayoutInflater inflater=null;


public NotiFicationListAdapter(ArrayList data)
{
this.data=data;        
    inflater =(LayoutInflater)baseActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}



public int getCount() 
{
 return data.size();
}



public Object getItem(int position) 
{
 return position;
}



public long getItemId(int position) 
{
    return position;
}



public View getView(int position, View convertView, ViewGroup parent) 
{
View vi=convertView;
    if(convertView==null)

    vi = inflater.inflate(R.layout.notification_list_item, null);

    ImageView compleatImageView=(ImageView)vi.findViewById(R.id.complet_image);
    TextView name = (TextView)vi.findViewById(R.id.game_name); // name
    TextView email_id = (TextView)vi.findViewById(R.id.e_mail_id); // email ID
    TextView notification_message = (TextView)vi.findViewById(R.id.notification_message); // notification message



    compleatImageView.setBackgroundResource(R.id.address_book);
    name.setText(data.getIndex(position));
    email_id.setText(data.getIndex(position));
    notification_message.setTextdata.getIndex(position));

    return vi;
}

  }

BaseAdapter xml file.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/inner_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"
android:layout_marginLeft="10dp"
android:layout_weight="4"
android:background="@drawable/list_view_frame"
android:gravity="center_vertical"
android:padding="5dp" >

<TextView
    android:id="@+id/game_name"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Game name"
    android:textColor="#FFFFFF"
    android:textSize="15dip"
    android:textStyle="bold"
    android:typeface="sans" />

<TextView
    android:id="@+id/e_mail_id"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/game_name"
    android:layout_marginTop="1dip"
    android:text="E-Mail Id"
    android:textColor="#FFFFFF"
    android:textSize="10dip" />

<TextView
    android:id="@+id/notification_message"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/game_name"
    android:layout_toRightOf="@id/e_mail_id"
    android:paddingLeft="5dp"
    android:text="Notification message"
    android:textColor="#FFFFFF"
    android:textSize="10dip" />



<ImageView
    android:id="@+id/complet_image"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:layout_marginBottom="30dp"
    android:layout_marginRight="10dp"
    android:src="@drawable/complete_tag"
    android:visibility="invisible" />

</RelativeLayout>

Change it accordingly and use.

I suggest using a custom Adapter, first create a Xml-file, for example layout/customlistview.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" >
    <ImageView
        android:id="@+id/image"
        android:layout_alignParentRight="true"
        android:paddingRight="4dp" />
    <TextView
        android:id="@+id/title"
        android:layout_toLeftOf="@id/image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="23sp"
        android:maxLines="1" />
    <TextView
        android:id="@+id/subtitle"
        android:layout_toLeftOf="@id/image" android:layout_below="@id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" /> 
</RelativeLayout>

Assuming you have a custom class like this

public class CustomClass {

    private long id;
    private String title, subtitle, picture;

    public CustomClass () {
    }

    public CustomClass (long id, String title, String subtitle, String picture) {
        this.id = id;
        this.title= title;
        this.subtitle= subtitle;
        this.picture= picture;
    }
    //add getters and setters
}

And a CustomAdapter.java uses the xml-layout

public class CustomAdapter extends ArrayAdapter {

private Context context;
private int resource;
private LayoutInflater inflater;

public CustomAdapter (Context context, List<CustomClass> values) { // or String[][] or whatever

    super(context, R.layout.customlistviewitem, values);

    this.context = context;
    this.resource = R.layout.customlistview;
    this.inflater = LayoutInflater.from(context);
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    convertView = (RelativeLayout) inflater.inflate(resource, null);

    CustomClass item = (CustomClass) getItem(position);

    TextView textviewTitle = (TextView) convertView.findViewById(R.id.title);
    TextView textviewSubtitle = (TextView) convertView.findViewById(R.id.subtitle);
    ImageView imageview = (ImageView) convertView.findViewById(R.id.image);

    //fill the textviews and imageview with the values
    textviewTitle = item.getTtile();
    textviewSubtitle = item.getSubtitle();

    if (item.getAfbeelding() != null) {
        int imageResource = context.getResources().getIdentifier("drawable/" + item.getImage(), null, context.getPackageName());
        Drawable image = context.getResources().getDrawable(imageResource);
    }
    imageview.setImageDrawable(image);

    return convertView;
    }
}

Did you manage to do it? Feel free to ask if you want more info on something :)

EDIT: Changed the adapter to suit a List instead of just a List

Excuse me; please explain that how can i use this class in my activity containing a listview named "lv" ,and what is purpose of "toerismelistviewitem" in this line: "super(context, R.layout.toerismelistviewitem, values);" — Mohsen Bahman, May 02 '13 at 09:30
Hi there, just fill in the name of your Xml-file, so in your case it will be super(context, R.layout.lv, values) - I forgot to rename it :) and I just got a List values but probably want your strings in a list with 2 dimensions because you have a title and subtitle, you can change it in whatever you want, remember that. — T_D, May 02 '13 at 09:49
I used a List instead of List so it will give both Strings and an url for the image. See my edit, I hope it's clear now... — T_D, May 02 '13 at 10:18
