für mich Dieser Code funktioniert Bitte versuchen Sie es

public void btnMyPicsClick(View v) { 
    thredFlag = 1; 
    outLineImage.setVisibility(View.INVISIBLE); 
    saveImageAdapter = new SaveImageAdapter(DrawAppActivity.this); 
    LayoutInflater inflater = (LayoutInflater) DrawAppActivity.this 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    DisplayMetrics displayMetrics = new DisplayMetrics(); 
    getWindowManager().getDefaultDisplay().getMetrics(displayMetrics); 
    final PopupWindow popupWindow = new PopupWindow(inflater.inflate(
      R.layout.mypicturesgrid, null, false), 1230, 250, true); 
    popupWindow.showAtLocation(findViewById(R.id.relativeLayoutBottom), 
      Gravity.LEFT, 30, -240); 
    View myPoppyView = popupWindow.getContentView(); 
    Button btnClose = (Button) myPoppyView.findViewById(R.id.btnColorClose); 
    GridView gvOutLine = (GridView) myPoppyView 
      .findViewById(R.id.gvOutline); 
    gvOutLine.setAdapter(saveImageAdapter); 
    gvOutLine.setOnItemClickListener(new OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> arg0, View v, int position, 
       long id) { 
      // TODO Auto-generated method stub 
      String path = saveImageAdapter.fileName[position] 
        .getAbsolutePath(); 
      File file = new File(path); 
      Uri uri = Uri.fromFile(file); 
      myPicImageUri = Uri.fromFile(file); 
      DisplayMetrics metrics = getApplicationContext().getResources() 
        .getDisplayMetrics(); 
      int w = metrics.widthPixels; 
      int h = metrics.heightPixels; 
      Bitmap bmp; 
      try { 
       bmp = BitmapFactory.decodeStream(getContentResolver() 
         .openInputStream(uri)); 
       Bitmap scaledBitmap = Bitmap.createScaledBitmap(bmp, w, h, 
         true); 
       drawingSurface.setBitmap(scaledBitmap); 
       drawingSurface.clear(); 
       popupWindow.dismiss(); 
      } catch (FileNotFoundException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
     } 
    }); 
    btnClose.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 
      popupWindow.dismiss(); 
     } 
    }); 
}
