I'm trying to create a custom gallery that allows users to pick from all the photos and videos contained on their Android device. I know how to create a gallery of just photos and just videos, but if I want to combine both, how can I do this?
I think the issue comes down to how I create my cursor. To select all videos, I created the cursor this way:
String[] videoParams = {MediaStore.Video.Media._ID,
MediaStore.Video.Media.DATA,
MediaStore.Video.Media.DATE_TAKEN,
MediaStore.Video.Thumbnails.DATA};
videocursor = getContentResolver().query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, videoParams, null, null, null);
If I want to query all the media files, not just video, what do I do?
This is what I tried, based off of: Custom Gallery with Images and Videos in android to select multiple items
String selectionMimeType = MediaStore.Files.FileColumns.MIME_TYPE + "=?";
String jpg_mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("jpg");
String png_mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("png");
String mp4_mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("mp4");
String[] selectionArgs = new String[]{jpg_mimeType, png_mimeType, mp4_mimeType};
mediaCursor = getContentResolver().query(MediaStore.Files.getContentUri("internal"), null, selectionMimeType, selectionArgs, MediaStore.Files.FileColumns.DATE_ADDED);
This gives me the error java.lang.IllegalArgumentException: Cannot bind argument at index 3 because the index is out of range. The statement has 1 parameters at android.database.DatabaseUtils.readExceptionFromParcel(DatabaseUtils.java:167)
Perhaps my approach is completely wrong, but I can't find any examples of custom android galleries using both images and videos, which is bizarre to me as this seems like it would be a common thing to create.
Here's all of my code, in case it's helpful:
public class GridViewCompatActivity extends Activity {
GridViewCompat gridView;
private static final String TAG = "GridViewCompatActivity";
Cursor videocursor;
Cursor mediaCursor;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_grid_view_compat);
gridView = (GridViewCompat) findViewById(R.id.gridView1);
// NOTE: We are using setChoiceMode, as I said, its a drop-in replacement
gridView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
gridView.setAdapter(new ImageAdapter(getApplicationContext()));
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> view, View arg1, int pos, long id) {
// We need to invalidate all views on 4.x versions
GridViewCompat gridView = (GridViewCompat) view;
gridView.invalidateViews();
}
});
findViewById(R.id.button1).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
SparseBooleanArray checkArray;
checkArray = gridView.getCheckedItemPositions();
String selectedPos = "Selected positions: ";
int count = checkArray.size();
for (int i = 0; i < count; i++) {
if (checkArray.valueAt(i))
selectedPos += checkArray.keyAt(i) + ",";
}
Intent intent = new Intent();
intent.putExtra("result", selectedPos);
setResult(Activity.RESULT_OK, intent);
finish();
}
});
}
public class ImageAdapter extends BaseAdapter {
private Context mContext;
public ImageAdapter(Context c) {
mContext = c;
}
public int getCount() {
Log.d(TAG, "number of media: " + Integer.toString(MediaStore.Files.FileColumns.DATA.length()));
int mediaParams = MediaStore.MediaColumns.DATA.length();
return mediaParams;
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
// create a new grid view item for each item referenced by the Adapter
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
CheckBox checkBox;
if (convertView == null) {
LayoutInflater layoutInflater = LayoutInflater.from(mContext);

}

if (checkArray != null) {

}
}
}
// imageView.setImageResource(mThumbIds[position]);
Bitmap bmThumbnail;
Log.d(TAG, "position: " + position);
mediaCursor = getContentResolver().query(MediaStore.Files.getContentUri("internal"), null, selectionMimeType, selectionArgs, MediaStore.Files.FileColumns.DATE_ADDED);
Log.d(TAG, Integer.toString(mediaCursor.getCount()));
for (int i = 0; i < mediaCursor.getCount(); i++){
mediaCursor.moveToPosition(i);
Boolean isVideo = mediaCursor.getString(mediaCursor.getColumnIndex(MediaStore.Video.Thumbnails.DATA)).length() > 0;
Log.d(TAG, "isVideo: " + isVideo);
String mediaPath = "";
if(isVideo){
mediaPath = mediaCursor.getString(mediaCursor.getColumnIndex(MediaStore.Video.Thumbnails.DATA));
video_paths.add(mediaPath);
}else{
mediaPath = mediaCursor.getString(mediaCursor.getColumnIndex(MediaStore.Images.Media.DATA));
video_paths.add(mediaPath);
}
Log.d(TAG, "mediaPath: " +mediaPath);
}
mediaCursor.moveToPosition(position);
String video_path = mediaCursor.getString(mediaCursor.getColumnIndex(MediaStore.Video.Thumbnails.DATA));
Log.d(TAG, "video_path: " + video_path);
imageView.setImageBitmap(ThumbnailUtils.createVideoThumbnail(video_path, Thumbnails.MICRO_KIND));
return convertView;
}
ArrayList<String> video_paths = new ArrayList<String>();
String selectionMimeType = MediaStore.Files.FileColumns.MIME_TYPE + "=?";
String jpg_mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("jpg");
String png_mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("png");
String mp4_mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("mp4");
String[] selectionArgs = new String[]{jpg_mimeType, png_mimeType, mp4_mimeType};
// String[] videoParams = {MediaStore.Video.Media._ID,
// MediaStore.Video.Media.DATA,
// MediaStore.Video.Media.DATE_TAKEN,
// MediaStore.Video.Thumbnails.DATA};
// }
}
}
