title: Using custom simpleCursorAdapter
body: <p>I am trying to access a list-activity using custom adapter.I have tried it directly without using any custom adapter it was working good but because I want to add more functions in list-view I want to implement a custom adapter.Now I have tried it but I am getting an empty list-view with no data visible.
  List-Activity</p>
  
  <pre><code>public class MainActivity extends ListActivity {
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
  
          String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";
  
           String[] projection = {
                      MediaStore.Audio.Media._ID,
                      MediaStore.Audio.Media.ARTIST,
                      MediaStore.Audio.Media.TITLE,
                      MediaStore.Audio.Media.DATA,
                      MediaStore.Audio.Media.DISPLAY_NAME,
                      MediaStore.Audio.Media.DURATION,
  
              };
              //query 
  
              musiccursor = this.managedQuery(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,projection,selection,null,sortOrder);
              music_column_index = musiccursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
  
  
              int a[]= new int[]{R.id.TitleSong,R.id.Artist};
  
  
              Custom_Adapter adapter = new Custom_Adapter(this,R.layout.music_items, musiccursor, new String[]{MediaStore.Audio.Media.TITLE,MediaStore.Audio.Media.ARTIST} ,a);
  
              this.setAdapter(adapter);
  
              }
      }
