//根据一些建议，我在我的项目中编写了这段代码，但仍面临同样的问题

@Override

    public void onActivityResult(int requestCode, int resultCode, Intent data) 
    {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if(requestCode == PICK_IMAGE/PICK_Camera_IMAGE && resultCode == Activity.RESULT_OK)
        {
               Fragment yourFragment = getSupportFragmentManager().findFragmentById(R.id.frame_container); // same tag while adding fragment for the first time.
               if (yourFragment != null) 
        {

                   yourFragment.onActivityResult(requestCode, resultCode, data); //calling method that should be defined in your fragment.

         }
         }
    }

//此代码来自MainActivity.java类.. //我应该将以上活动结果代码写入我的Mainfragment类吗？

                    intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
                    intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
                    startActivityForResult(intent, PICK_Camera_IMAGE);
        }
        });

// This is the code belongs to my Profile Fragment class..
// I stuck over here didn't get any kind of solution 
// I'm using fragment viewpager

Answer 1

如果这样做，你就错了 ** PICK_IMAGE / PICK_Camera_IMAGE ** 它将划分您的请求代码，结果代码将不同

 if(requestCode == PICK_IMAGE/PICK_Camera_IMAGE && resultCode ==Activity.RESULT_OK)
  {
     //...
  }

使用此代码代替旧版

if(requestCode == PICK_IMAGE && resultCode == Activity.RESULT_OK)
 {
         //...
}else if(requestCode == PICK_Camera_IMAGE && resultCode ==Activity.RESULT_OK)
{
         //...
}

Answer 2

要在片段中获得结果，请务必致电

startActivityForResult(intent, PICK_Camera_IMAGE);

而不是

getActivity().startActivityForResult(intent, PICK_Camera_IMAGE);

在你的片段里面

。

Answer 3

由于所有片段都被调用到一个活动中，因此必须将结果从您正在执行的活动的onActivityResult转移到片段中。

您必须在片段中创建自己的onActivityResult方法，并使用相同的签名来更新片段UI。

Answer 4

删除此

super.onActivityResult(requestCode, resultCode, data);

片段问题它不支持活动结果
