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

I want to show all videos from a specific folder in android activity. so when user click on it, video will play maybe on android internal video player or etc. Please help me to achieve my tasks. I am also posting a picture of my desired output. I want list videos just like in the picture.this is picture of MX-player, i want same functionality in my application
Try the piece of code given below:
videocursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
proj, null, null, null);
count = videocursor.getCount();
videolist = (ListView) findViewById(R.id.listview);
videolist.setAdapter(new VideoAdapter(getApplicationContext()));
videolist.setOnItemClickListener(videogridlistener);
}
private OnItemClickListener videogridlistener = new OnItemClickListener() {
public void onItemClick(AdapterView<?>parent, View v, int position,
long id) {
System.gc();
video_column_index = videocursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
videocursor.moveToPosition(position);
String filename = videocursor.getString(video_column_index);
Intent intent = new Intent(VideoActivity.this, ViewVideo.class);
intent.putExtra("videofilename", filename);
startActivity(intent);
}
};
public class VideoAdapter extends BaseAdapter {
private Context vContext;
public VideoAdapter(Context c) {
vContext = 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(vContext.getApplicationContext());
String id = null;
if (convertView == null) {
video_column_index = videocursor.getColumnIndexOrThrow(MediaStore.Video.Media.TITLE);
videocursor.moveToPosition(position);
id = videocursor.getString(video_column_index);
tv.setText(id);
}
else
{
tv = (TextView) convertView;
return tv;
}
Let me know if you are facing any issue with this, I'll be happy to help you.
I'm listing video from device memory with a BaseAdapter and I've noticed that scrolling is not very performing, very slow.
Should I use a different method to do this work or is there a way to improve this one ?

ListView Adapter's getView() method will be called numerous times as you scroll the List. So you should not perform any operation that takes more time or more memory. Otherwise bear with slow performance or crash.
Let's see how you can optimize:
Avoid operations that takes more time or memory
Do not call managedQuery() from your getView which will affect the performance badly. And you are creating thumbnails there. I wouldn't do that if I need more responsive ListView. If you need them so badly, go for AsyncTask.
Reuse the View
The adapters, by default, recycles the views during getView calls to avoid unnecessary object creation. Yikes! Go for it. It's just simple.
View v = convertView;
if(v == null) {
//inflate view
}
// do the rest
Include ViewHolder Patter
The ViewHolder pattern brings the smoothness into the ListView. If you want sleek scroll, read
http://developer.android.com/training/improving-layouts/smooth-scrolling.html
http://www.vogella.com/tutorials/AndroidListView/article.html
PS: The System.gc() call is not the best option to free up memory. Let's see what he Android Doc says,
System.gc() indicates to the VM that it would be a good time to run the garbage collector. Note that this is a hint only. There is no guarantee that the garbage collector will actually be run.
you should not assign every time null to the convertView
convertView = null;
if (convertView == null) {
remove convertView = null. Get rid also of System.gc();

How to get thumbnails from a specific folder in sd card. I am using this tutorial http://gypsynight.wordpress.com/2012/02/17/how-to-show-all-video-file-stored-in-your-sd-card-in-a-listview/
It can be done easily this way:
int videoId = videoCursor.getInt(videoCursor.getColumnIndexOrThrow(MediaStore.Video.Media._ID));
ContentResolver cr = getContentResolver();
BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 1;
Bitmap curThumb = MediaStore.Video.Thumbnails.getThumbnail(cr, videoId, MediaStore.Video.Thumbnails.MICRO_KIND, options);
thumbImage.setImageBitmap(curThumb);
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 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?
