Question

使用Gallery中的图片成功执行此技术但我想为音频和视频实现相同的功能。代码是

public void video(View v)
{
    Intent i = new Intent(Intent.ACTION_PICK,
            android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI);
    RESULT_LOAD_VIDEO = 1;
    startActivityForResult(i, RESULT_LOAD_VIDEO);
}   
public void audio(View v)
{
    Intent i = new Intent(Intent.ACTION_PICK,
            android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
    RESULT_LOAD_AUDIO = 1;
    startActivityForResult(i, RESULT_LOAD_AUDIO);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);



      if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK &&null != data)
      {
          Uri selectedImage = data.getData(); String[]
      filePathColumn = { MediaStore.Images.Media.DATA };

      Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
      cursor.moveToFirst();

      int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
      String picturePath = cursor.getString(columnIndex); cursor.close();

      // String picturePath contains the path of selected Image

      NewPoll.flag++;
      Path.patha= picturePath;
      Intent ints=new  Intent(getApplicationContext(),NewPoll.class);
      ints.putExtra("address",picturePath);
      ints.putExtra("option",comingData);
      startActivity(ints); 
      }


      if (requestCode == RESULT_LOAD_VIDEO && resultCode == RESULT_OK &&null != data)
      {
          Uri selectedVideo= data.getData(); String[]
      filePathColumn = { MediaStore.Video.Media.DATA };

      Cursor cursor = getContentResolver().query(selectedVideo,filePathColumn, null, null, null);
      cursor.moveToFirst();

      int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
      String videoPath = cursor.getString(columnIndex); cursor.close();

      // String picturePath contains the path of selected Image

      NewPoll.flag++;
      Path.patha= videoPath;
      Intent ints=new  Intent(getApplicationContext(),NewPoll.class);
      ints.putExtra("address",videoPath);
      ints.putExtra("option",comingData);
      startActivity(ints); 
      }




      if (requestCode == RESULT_LOAD_AUDIO && resultCode == RESULT_OK &&null != data)
      {
          Uri selectedAudio= data.getData(); String[]
      filePathColumn = { MediaStore.Audio.Media.DATA };

      Cursor cursor = getContentResolver().query(selectedAudio,filePathColumn, null, null, null);
      cursor.moveToFirst();

      int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
      String audioPath = cursor.getString(columnIndex); cursor.close();

      // String picturePath contains the path of selected Image

      NewPoll.flag++;
      Path.patha= audioPath;
      Intent ints=new  Intent(getApplicationContext(),NewPoll.class);
      ints.putExtra("address",audioPath);
      ints.putExtra("option",comingData);
      startActivity(ints); 
      }

}

我在照片库方面取得了成功但却不知道如何使用视频和音频库来自你方的代码是适当的！感谢

//from this u get all audio 
    private void getallaudio()
    {

        String[] STAR = { "*" };


        Cursor audioCursor = ((Activity) cntx).managedQuery(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, STAR, null, null, null);
        if (audioCursor != null) 
        {
            if (audioCursor.moveToFirst()) 
            {
                do 
                {

                    String path = audioCursor.getString(audioCursor.getColumnIndex(MediaStore.Audio.Media.DATA));
                    controller.audioWrapper.add(new MediaWrapper(new File(path).getName(), path, "Audio",false,color_string));
//                    Log.i("Audio Path",path);
                }while (audioCursor.moveToNext());

            }
//            audioCursor.close();
        }
    }

    //from this u get all video
    private void getallvideo()
    {
         String[] STAR = { "*" };


        controller.videoWrapper.clear();
        Cursor videoCursor = ((Activity) cntx).managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, STAR, null, null, null);
        if (videoCursor != null) 
        {
            if (videoCursor.moveToFirst()) 
            {
                do 
                {


                    String path = videoCursor.getString(videoCursor.getColumnIndex(MediaStore.Images.Media.DATA));
                    controller.videoWrapper.add(new MediaWrapper(new File(path).getName(), path, "Video",false,color_string));
//                    Log.i("Video Path",path);
                }while (videoCursor.moveToNext());

            }
//            videoCursor.close();
        }
    }

如何从图库中选择视频并将所选视频图标设置为ImageView
