Android 如何从gallery中选择视频并将所选视频图标设置为ImageView

使用Gallery中的图片成功地执行了此技术 但我想在音频和视频中实现同样的功能。 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); 
      }

}

我的照片库很成功，但不知道如何使用视频和音频库 收到你方的代码！

谢谢

什么是控制器？？忽略它实际上它是我保存数据的类名，你可以将数据保存到任何地方确定！我试过你的代码，它没有错误，我试过调试，你的代码正在执行，但没有输出，它甚至没有打开图库…都德，它只给你所有的图像细节，如名称路径等，然后你只需要让一个适配器获取网格视图，并利用我的数据进行设置：）它的自定义都德

//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
