Question

我在使用Fragment中的相机意图时遇到问题。我有一个包含片段的Activity，我有四个片段。在我的第三个片段中，我调用了相机Intent。拍照后，应用程序不会仅在第3个片段上恢复，但它也会出现第1个片段。你可以看到图片和代码。

感谢任何解决方案。

代码：

public class CreateAttachment extends Fragment{

private RelativeLayout btnBack, btnNext;
private LinearLayout btnAttachment, btnCapture;

private static final int CAMERA_REQUEST_CODE = 100;
public static final int MEDIA_TYPE_IMAGE = 1;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.create_property_attachment, container, false);

    btnBack = (RelativeLayout) view.findViewById(R.id.attachment_btnBack);
    btnBack.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            getFragmentManager().popBackStack();
        }
    });

    btnNext = (RelativeLayout) view.findViewById(R.id.attachment_btnNext);
    btnNext.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            nextFragment();
        }
    });

    btnAttachment = (LinearLayout) view.findViewById(R.id.btnAttachment);
    btnAttachment.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) { 
            Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            intent.putExtra("return-data", true);
            startActivityForResult(Intent.createChooser(intent, "Complete action using"), MEDIA_TYPE_IMAGE);
        }
    });

    btnCapture = (LinearLayout) view.findViewById(R.id.btnCameraAccess);
    btnCapture.setOnClickListener(new View.OnClickListener(){

        @Override
        public void onClick(View v) {
            Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, CAMERA_REQUEST_CODE);
        }
    });

    return view;
}


@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if(resultCode == Activity.RESULT_OK && requestCode == MEDIA_TYPE_IMAGE){

        Toast.makeText(getActivity(),"Photo is Chosen",Toast.LENGTH_SHORT).show();
    }
    else if (requestCode == CAMERA_REQUEST_CODE && resultCode == Activity.RESULT_OK) {

        Toast.makeText(getActivity(),"Photo is Captured",Toast.LENGTH_SHORT).show();
    }
  }
}

图片： Here is my screenshot for 1st fragment, 3rd fragment, and the issue after take a picture by Camera Intent in the 3rd fragment.

Answer 1

试试这个

  Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent,
                        CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

在OnActivityResult中

删除super.onActivityResult(requestCode, resultCode, data);

  @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {



    }

Answer 2

您的问题可能出在您的添加/替换片段代码中。你的第一和第三个片段是重叠的，因为你可能没有隐藏（片段化）你的片段用第三个片段替换第一个片段。

Answer 3

感谢您的所有答案。无论如何，我并不确切地知道错误是什么，但解决这个问题的方法是覆盖我的第3个片段上的Activity的这两个函数。

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Toast.makeText(getActivity(), "Work on onCreate when return into Fragment.", Toast.LENGTH_SHORT).show();
}


@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
}
