Multiple listviews in one layout android

Question

I want to populate two listviews in one activity. For that i placed two listviews in one layout. My problem is that both listviews are populated but only one listview is visible. Now when i make one layout INVISIBLE, it will display another listview.

Here i am posting my xml file. Is there any problem in my layout ? Please suggest solution.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:paddingTop="10dp"
    android:id="@+id/playlist_lyt"
    >

    <Button 
        android:id="@+id/btnAlbumwise"
        android:text="View Albumwise"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"        
        />

    <RelativeLayout 
        android:id="@+id/layout_songlist"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical"
        android:paddingTop="10dp"
        android:layout_below="@+id/layout_albumlist"  
        >

        <EditText android:id="@+id/inputSearch"

            android:inputType="textVisiblePassword"
            android:cursorVisible="false"
            android:background="@drawable/rounded_edittext" 
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"            
        />

        <ListView
            android:id="@android:id/list"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"

            android:listSelector="@drawable/list_selector"
            android:layout_below="@+id/inputSearch" 
            android:paddingTop="8dp"/>

    </RelativeLayout>

    <RelativeLayout
        android:id="@+id/layout_albumlist"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical"
        android:paddingTop="10dp"
        android:layout_below="@+id/btnAlbumwise"        
        >

         <ListView  
            android:id="@+id/liist"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:divider="#242424"
            android:dividerHeight="1dp"
            android:listSelector="@drawable/list_selector"
        />
    </RelativeLayout>
</RelativeLayout>

Code to populate listview "liist". PlaylistActivity.java

      Cursor cursor1 = managedQuery(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, null,null, null, null);
      if (cursor1 == null) 
      {
          //Query Failed , Handle error.
      }
      else if (!cursor1.moveToFirst()) 
      {
         //No media on the device.
      }
      else
      {   
        //  int albumName = cursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM);
          int id = cursor1.getColumnIndex(MediaStore.Audio.Albums._ID);
          int albumartist = cursor1.getColumnIndex(MediaStore.Audio.Albums.ARTIST);

          for(int i=0;i<cursor1.getCount();i++)
          {
                String Name = cursor1.getString(cursor1.getColumnIndex(MediaStore.Audio.Albums.ALBUM));
                Integer albumid = cursor1.getInt(id);                       
                String artist = cursor1.getString(albumartist);

                Bitmap bitmap = null;
                bitmap = getArtwork(context, albumid);
                    lstImage.add(bitmap);
                    lstName.add(Name);
                    lstArtist.add(artist);

                cursor1.moveToNext();
           }
       }
       cursor1.close();                    

       rowItems = new ArrayList<RowItem>();
        for (int i = 0; i < lstName.size(); i++) {
            RowItem item = new RowItem(lstImage.get(i), lstName.get(i) , lstArtist.get(i));
            rowItems.add(item);
        }          
        CustomListViewAdapter adapter = new CustomListViewAdapter(PlayListActivity.this,
                R.layout.list_item, rowItems);
        lv1.setAdapter(adapter);
        lv1.setOnItemClickListener(new OnItemClickListener() {

            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                // TODO Auto-generated method stub
                RowItem item = rowItems.get(position);
                String title = item.getTitle();
                Intent in = new Intent(PlayListActivity.this,AlbumsongListActivity.class);

                // Sending songIndex to PlayerActivity
                in.putExtra("albumTitle", title);
                in.putExtra("list", 0);
                in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(in);

            }
        });

Now when i click on item it starts another activity Albumsonglistactivity.java

public class AlbumsongListActivity extends ListActivity {
@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
String[] from = { "songTitle", "artist" };
        int[] to = { R.id.album_songTitle, R.id.album_songArtist };
        adapter = new SimpleAdapter(this, getAlbumSongList(context),
                R.layout.albumsonglist_item, from, to) 
        {
            public long getItemId(int position) 
            {
                return songsListData.indexOf(getItem(position));
            }
        };

        setListAdapter(adapter);
        ListView lv = getListView();
        lv.setOnItemClickListener(new OnItemClickListener() 
        {
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) 
            {
                // getting listitem index
                int songIndex = (int) id;

                // Starting new intent
                Intent in = new Intent(getApplicationContext(),MusicPlayertemp.class);
                in.putExtra("songIndex", songIndex);
                in.putExtra("albumtitle", albumName);
                in.putExtra("listFlag", 3);
                startActivity(in);              
            }
        });
    }

    public ArrayList<HashMap<String, String>> getAlbumSongList(Context c) 
    {
        String whereClause = MediaStore.Audio.Media.ALBUM + " = ? ";
        String s[] = new String[] { albumName };
        Cursor cursor = c.getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, null, whereClause,s, MediaStore.Audio.Media.TITLE);
        if (cursor == null) 
        {
            // Query Failed , Handle error.
        } 
        else if (!cursor.moveToFirst()) 
        {
            // No media on the device.
        } 
        else 
        {
            int titleColumn = cursor.getColumnIndex(android.provider.MediaStore.Audio.Media.TITLE);
            int idColumn = cursor.getColumnIndexOrThrow(android.provider.MediaStore.Audio.Media.DATA);
            int artistcolumn = cursor.getColumnIndex(android.provider.MediaStore.Audio.Media.ARTIST);
            albumid = cursor.getInt(cursor.getColumnIndex(android.provider.MediaStore.Audio.Media.ALBUM_ID));
            int id = cursor.getColumnIndex(android.provider.MediaStore.Audio.Media._ID);
            for (int i = 0; i < cursor.getCount(); i++) 
            {
                String thisTitle = cursor.getString(titleColumn);
                String path = cursor.getString(idColumn);
                String artist = cursor.getString(artistcolumn);         
                String ID = cursor.getString(id);
                HashMap<String, String> song = new HashMap<String, String>();
                song.put("songTitle", thisTitle);
                song.put("songPath", path);
                song.put("artist", artist);
                song.put("id", ID);
                // Adding each song to SongList
                songsList.add(song);
                cursor.moveToNext();
            }
        }
        // looping through playlist
        for (int i = 0; i < songsList.size(); i++) 
        {
            // creating new HashMap
            HashMap<String, String> song = songsList.get(i);
            // adding HashList to ArrayList
            songsListData.add(song);
        }
        return songsListData;
    }

In albumsonglistActivity, if i click on item it doesn't invoked..

Answer 1

This is the problem because you are setting another layout below the first one and first one takes height to fill_parent.

You should use Linear Layout and put both listview inside that and use layout_weight property to make both listview same height.

For example you can follow below hierarchy. Its not original code but it just a structure which you can use to develop your layout

<LinearLayout orientation="verical">
   <ListView layout_weight=1></ListView>   
   <ListView layout_weight=1></ListView>
</LinearLayout>

Answer 2

you have given android:layout_height="fill_parent" to both Relative layout. this is why you are unable to show both listviews.

use linear layout and By using weight you can divide the screen for displaying both listviews
