这是我的onActivityResult方法：-

         if (requestCode == 1)
         {
             if (intent != null && resultcode == RESULT_OK)
             {             

                 Uri selectedImage = intent.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 filePath = cursor.getString(columnIndex);
                   Log.v("log","filePath is : "+filePath);

Answer 1

另一种做法是这样的。

1. 在按钮上单击（您想要打开的）打开另一个活动。
2. 在另一个活动的onCreate（）上打开该意图。
3. OnActivityResult设置上一个活动和调用finish（）上的静态数据。
4. 这样就不会有人知道您打开了这样的活动，您将获得您的数据。
