    Hi,

    I am new in Android. I am trying an example for which I am trying to write custom layout file row.xml other then default main.xml.

    Below is main.xml which is default generated.
    Code (Text):
    1. <?xml version="1.0" encoding="utf-8"?>
    2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    3.     android:orientation="horizontal"
    4.     android:layout_width="fill_parent"
    5.     android:layout_height="wrap_content"
    6.     >
    7. <ImageView
    8. android:id="@+id/icon"
    9. android:layout_width="22px"
    10. android:paddingLeft="2px"
    11. android:paddingRight="2px"
    12. android:paddingTop="2px"
    13. android:layout_height="wrap_content"
    14. android:src="@drawable/ok"
    15. />
    16.  
    17. <TextView
    18. android:id="@+id/label"
    19. android:layout_width="wrap_content"
    20. android:layout_height="wrap_content"
    21. android:textSize="44sp"
    22. />
    23. </LinearLayout>
    24.  
    StaticDemo.java

    Code (Text):
    1. import android.app.ListActivity;
    2. import android.os.Bundle;
    3. import android.view.View;
    4. import android.widget.ArrayAdapter;
    5. import android.widget.ListView;
    6. import android.widget.TextView;
    7.  
    8. public class StaticDemo extends ListActivity {
    9.     TextView selection;
    10.     String items[] = {"Kanpur","Lucknow","Agra","Banaras"};
    11.     /** Called when the activity is first created. */
    12.     @Override
    13.     public void onCreate(Bundle savedInstanceState) {
    14.         super.onCreate(savedInstanceState);
    15.         setContentView(R.layout.main);
    16.         setListAdapter(new ArrayAdapter<String>(this,[B]R.layout.row[/B],R.id.label,items));
    17.         selection = (TextView)findViewById(R.id.selection);
    18.     }
    19.     public void onListItemClick(ListView parent,View v,int position,long id){
    20.         selection.setText(items[position]);
    21.     }
    22. }
    In StaticDemo.java R.layout.row is used, So I have to write row.xml inside res/layout where default main.xml stay.

    output will be a list in which every list item contains image followed by text
    [​IMG]

    Please suggest how to write row.xml sothat this code will give output as above!

    row.xml (efforts by me):

    Code (Text):
    1. <?xml version="1.0" encoding="utf-8"?>
    2. <LinearLayout
    3. xmlns:android="http://schemas.android.com/apk/res/android"
    4. android:orientation="vertical"
    5. android:layout_width="fill_parent"
    6. android:layout_height="wrap_content" >
    7. <TextView
    8. android:id="@+id/selection"
    9. android:layout_width="fill_parent"
    10. android:layout_height="wrap_content"/>
    11. <ListView
    12. android:id="@android:id/list"
    13. android:layout_width="fill_parent"
    14. android:layout_height="fill_parent"
    15. android:drawSelectorOnTop="false"
    16. />
    17. </LinearLayout>
    regards

    You might want to try out this link to an Android example which shows the basics of using a list view. Once you have that working, adding an icon is fairly simple. Just add an Imageview to the row.xml.

    Good luck!
