问题
i want to create a custom gallery to display all images and videos(along with duration) in sdcard. i am using the following code to build a custom gallery
Code:
final String[] columns = { MediaStore.Images.Media.DATA ,MediaStore.Images.Media._ID};
final String orderBy = MediaStore.Images.Media.DATE_TAKEN;
Cursor imagecursor = getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null,
null, orderBy + " DESC");
this.imageUrls = new ArrayList<String>();
for (int i = 0; i < imagecursor.getCount(); i++) {
imagecursor.moveToPosition(i);
int dataColumnIndex = imagecursor.getColumnIndex(MediaStore.Images.Media.DATA);
imageUrls.add(imagecursor.getString(dataColumnIndex));
}
String[] parameters = { MediaStore.Video.Media._ID,
MediaStore.Video.Media.DATA,
MediaStore.Video.Media.DISPLAY_NAME,
MediaStore.Video.Media.SIZE, MediaStore.Video.Media.DURATION,
MediaStore.Video.Media.DATE_TAKEN,MediaStore.Video.Thumbnails.DATA};
Cursor videocursor = getContentResolver().query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
parameters, null, null, null);
for (int i = 0; i < videocursor.getCount(); i++) {
videocursor.moveToPosition(i);
imageUrls.add(videocursor.getString(videocursor.getColumnIndex(MediaStore.Video.Thumbnails.DATA)));
}
options = new DisplayImageOptions.Builder()
.showStubImage(R.drawable.stub_image)
.showImageForEmptyUri(R.drawable.image_for_empty_url)
.cacheInMemory()
.cacheOnDisc()
.build();
imageAdapter = new ImageAdapter(this, imageUrls);
from the above code i am able to get the path of the video, how can i get the video thumbnail along with video duration. and represent it in the gallery
if there are any buit in projects for custom gallery with videos and images please post the links i actually want to create a custom gallery to select multiple image and video files. i searched a lot in google i am finding the custom image gallery but not with videos please help me in solving this problem.
回答1:
You can take idea from Custom GridView with multiple option selection option. There is an open source project in Github.
https://github.com/paramvir-b/AndroidGridViewCompatLib

in this example you need to change
imageView.setImageResource(mThumbIds[position]);
to
imageView.setImageURI(uri);// URI of Image from SD Card
or
imageView.setImageBitmap(bitmap);
For Video:-
Video Thumbnail is in the form of Bitmap so you can show in ImageView.
private Bitmap bmThumbnail;
private ImageView videoview = null;
bmThumbnail = ThumbnailUtils.createVideoThumbnail(PATH_OF_THE_VIDEO,Thumbnails.MICRO_KIND);
videoview.setImageBitmap(bmThumbnail);
for getting Duration:-
String[] proj = { MediaStore.Video.Media.DATA ,MediaStore.Video.Media.DURATION};
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
if (cursor == null)
return null;
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
int column_index_duration = cursor
.getColumnIndexOrThrow(MediaStore.Video.Media.DURATION);
cursor.moveToFirst();
long duration= cursor.getInt(column_index_duration);
String videoPath= cursor.getString(column_index);

Getting Video Thumbnails and duration:
for(int ii = 0; ii < videocursor.getCount(); ii ++){
videocursor.moveToPosition(ii);
int id_v = videocursor.getInt(video_column_index);
int datacolumn_v = videocursor.getColumnIndex(MediaStore.Video.Media.DATA);
long duration = videocursor.getInt(video_column_duration); // getting duration of the every videos
String hms = String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(duration),
TimeUnit.MILLISECONDS.toMinutes(duration) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(duration)),
TimeUnit.MILLISECONDS.toSeconds(duration) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(duration)));
durationcount.add(hms);
bitList.add(MediaStore.Video.Thumbnails.getThumbnail(getContentResolver(), id_v,
MediaStore.Video.Thumbnails.MICRO_KIND, null));
arrPathList.add(videocursor.getString(datacolumn_v));
}

回答4:
int column_index_thumb_data = videoCursor.getColumnIndex(MediaStore.Video.Thumbnails.DATA);
String thumbnail = videoCursor.getString(column_index_thumb_data);
