Question

我尝试从图库中选择图像并在FRAGMENT中的图像视图中设置。但我完全得到了图片路径的值，但我无法获得值位图（它给出了空值）。注意：主要问题是位图给出空值而不是Nullpointer异常。

Intent i = new Intent(
                Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);      

startActivityForResult(i, RESULT_LOAD_IMAGE);

public void onActivityResult(int requestCode, int resultCode, Intent data) {
       Uri selectedImage = data.getData();
       String[] filePathColumn = { MediaStore.Images.Media.DATA };

      Cursor cursor = getActivity().getContentResolver().query(selectedImage,
                        filePathColumn, null, null, null);
      cursor.moveToFirst();         int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                String picturePath = cursor.getString(columnIndex);

       cursor.close();
       Bitmap b= BitmapFactory.decodeFile(picturePath);

这是我的logcat：

> bitmap null

位图在Android片段中给出null值
