如何使用sdcard中的FilePath获取媒体信息,如视频的标题和艺术家?
ACTIVITY A
public void onListItemClick(ListView l, View v, int position, long id) {
// MOVE TO CLICK POSITION
if (videoCursor.moveToPosition(position)); {
videoPathColumnIndex = videoCursor
.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
String path = videoCursor.getString(videoPathColumnIndex);
videoIntent = new Intent(this, Play.class);
videoIntent.putExtra("keykey", path);
videoIntent.putExtra("bmpbmp", bmp);
startActivity(videoIntent);
}
}
ACTIVITY B
private void getMediaInfo() {
videoIntent = getIntent();
extras = videoIntent.getExtras();
String path = extras.getString("keykey");
Bitmap = (Bitmap) videoIntent.getParcelableExtra("bmp");
MediaStore.Video.Media.
}
如何使用视频路径列出使用路径的视频标题,艺术家或持续时间? 如何正确传递不会影响性能问题的img?
