Ok so im making a media player app for android. everything was ok until now. so far i have a list view that shows all .mp3 files on ur sdcard(internal and external) and when playing show a music visualizer. but i cant for the life of me alphabetize the list. everything is dynamic so xml doesnt work here.
public class MusicPlayerActivity extends Activity {
ListView musiclist;
Cursor musiccursor;
int music_column_index;
int count;
private Intent aIntent;
public static String filename;
private RelativeLayout mRelativeLayout;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
init_phone_music_grid();
mRelativeLayout = new RelativeLayout(this);
setContentView(mRelativeLayout);
mRelativeLayout.addView(musiclist);
}
public void init_phone_music_grid() {
System.gc();
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,
MediaStore.Audio.Media.ALBUM
};
Uri allsongsuri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";
musiccursor = managedQuery(allsongsuri, projection , selection, null, null);
count = musiccursor.getCount();
musiclist = (ListView) findViewById(R.id.PhoneMusicList);
musiclist.setAdapter(new EfficientAdapter(getApplicationContext()));
musiclist.setOnItemClickListener(musicgridlistener);
}
private OnItemClickListener musicgridlistener = new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position,long id) {
System.gc();
music_column_index = musiccursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
musiccursor.moveToPosition(position);
filename = musiccursor.getString(music_column_index);
aIntent = new Intent(v.getContext(), AudioFX.class);
aIntent.getStringExtra(filename);
startActivity(aIntent);
}
};
class EfficientAdapter extends BaseAdapter {
private Context mContext;
public EfficientAdapter(Context c) {
mContext = c;
}
public int getCount() {
return count;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
System.gc();
String id = null;
TextView tv;
if (convertView == null) {
tv = new TextView(mContext.getApplicationContext());
} else{
tv = (TextView) convertView;
}
musiccursor.moveToPosition(position);
music_column_index = musiccursor
.getColumnIndexOrThrow(MediaStore.Audio.Media.TITLE);
id = musiccursor.getString(music_column_index);
tv.setText(id);
tv.setTextSize(20);
return tv;
}}}
You just need to use DEFAULT_SORT_ORDER, like this:
String sortOrder = MediaStore.Audio.Media.DEFAULT_SORT_ORDER;
musiccursor = managedQuery(allsongsuri, projection , selection, null, sortOrder);
Showing the title inside the getView method won't get a alphabetized list.
Inorder to alphabetize the list get all the music titles into a String array or an ArrayList
Alphabetize them manually and pass that String array to EfficientAdapters Constructor and store it locally and use them according to the lists position.
like
class EfficientAdapter extends BaseAdapter {
private Context mContext;
private String values[];
public EfficientAdapter(Context c, String[] a) {
mContext = c;
values = a;
}
public int getCount() {
return count;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
System.gc();
String id = null;
TextView tv;
if (convertView == null) {
tv = new TextView(mContext.getApplicationContext());
} else{
tv = (TextView) convertView;
}
id = values[position];
tv.setText(id);
tv.setTextSize(20);
return tv;
}}}
Hope this helps.....

I tried to make a list of videos, everything was right, the list is shown and you can see in videoview. but.
1) How can I add bitmap image in the list of videos?
2) How can I change the ListView, with Gridview?
Thank you

Use following code to display audio file in ListView and clicking on any one of it, plays that song
public class AudioListActivity extends Activity {

musiccursor = managedQuery(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,proj, null, null, null);
count = musiccursor.getCount();

if (mMediaPlayer.isPlaying()) {
mMediaPlayer.reset();

mMediaPlayer.start();
} catch (Exception e) {
}
}
};

For NPE, seems there's no textView1 view in R.layout.city_row_item.
Regarding showing list of music files and playing them, You could refer to this exemple.
Also, I believe You need to refer to this video from 2010 IO for creation of better adapters for ListViews (because in your code You don't use convertView item).
Use sound pool to load the sounds into the memory first. This is how I'm doing it in my app Beat Shaker:
// Sound pool new instance
spool = new SoundPool(3, AudioManager.STREAM_MUSIC, 0);
// Sound pool on load complete listener
spool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
#Override
public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
Log.i("OnLoadCompleteListener","Sound "+sampleId+" loaded.");
loaded = true;
}
});
// Load the sample IDs
soundId = new int[3];
soundId[0] = spool.load(this, R.raw.clave, 1);
soundId[1] = spool.load(this, R.raw.maracas, 1);
soundId[2] = spool.load(this, R.raw.crash, 1);
Then you can call a thread from the corresponding list selection listener that runs a function similar to this:
public void Sound1(){
AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
float volume = (float) audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
int streamID = -1;
do{
streamID = spool.play(soundId[0], volume, volume, 1, 0, 1f);
} while(streamID==0);
};
I am creating one application which record voice and store it in SD card. then i open
this file and want to play or some other option by clicking on that respective file.
But when i click on that list item it'd not playing. I don't understand where is the problem. Here is my code.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listofaudiorecord);
init_phone_music_grid();
}
private void init_phone_music_grid() {
System.gc();
String[] proj = { MediaStore.Audio.Media._ID,
MediaStore.Audio.Media.DATA,
MediaStore.Audio.Media.DISPLAY_NAME,
MediaStore.Video.Media.SIZE };
musiccursor = managedQuery(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
proj, null, null, null);
count = musiccursor.getCount();
musiclist = (ListView) findViewById(R.id.PhoneMusicList);
musiclist.setAdapter(new MusicAdapter(getApplicationContext()));
musiclist.setOnItemClickListener(musicgridlistener);
mMediaPlayer = new MediaPlayer();
}
private OnItemClickListener musicgridlistener = new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position,
long id) {
System.gc();
music_column_index = musiccursor
.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
musiccursor.moveToPosition(position);
String filename = musiccursor.getString(music_column_index);
try {
if (mMediaPlayer.isPlaying()) {
mMediaPlayer.reset();
}
mMediaPlayer.setDataSource(filename);
mMediaPlayer.prepare();
mMediaPlayer.start();
} catch (Exception e) {
}
}
};
public class MusicAdapter extends BaseAdapter {
private Context mContext;
public MusicAdapter(Context c) {
mContext = c;
}
public int getCount() {
return count;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
System.gc();
TextView tv = new TextView(mContext.getApplicationContext());
String id = null;
if (convertView == null) {
music_column_index = musiccursor
.getColumnIndexOrThrow(MediaStore.Audio.Media.DISPLAY_NAME);
musiccursor.moveToPosition(position);
id = musiccursor.getString(music_column_index);
music_column_index = musiccursor
.getColumnIndexOrThrow(MediaStore.Audio.Media.SIZE);
musiccursor.moveToPosition(position);
id += " Size(KB):" + musiccursor.getString(music_column_index);
tv.setText(id);
} else
tv = (TextView) convertView;
return tv;
}
}
}
Please give me any hint.
Thanks in Advance..
How about you switch the two
musiclist.setOnItemClickListener(musicgridlistener);
mMediaPlayer = new MediaPlayer();
to this
mMediaPlayer = new MediaPlayer();
musiclist.setOnItemClickListener(musicgridlistener);
or put the MediaPlayer reference inside the onItemClick()
i am able to show all videos from sdcard into ListView but how to show only specified videos from sdcard into Listview in android.Can anybody help please?
-I am showing all videos in Listview.
-show particular video file.
This is my Code.

I am using other way to get the names of the files from sdcard.
I am using files concept to do this as in How to display files on the SD card in a ListView?
