Question

我有1帧和2片段用于backstack但我遇到了问题。如果我将片段2添加到帧并添加到Backstack。我可以点击fragment2上的同一个地方，但效果是在片段1上。我怎么能解决这个问题？非常感谢！

Fragment1.java

public class Fragment1 extends Fragment {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_1,container,false);
    Button b = (Button)view.findViewById(R.id.btn1);
    b.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getActivity(),"FR1",Toast.LENGTH_SHORT).show();
        }
    });
    return view;
}

} BackstackActivity

public class BackstackActivity extends AppCompatActivity {
private Button btnFrag;
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_backstack);
    btnFrag = (Button) findViewById(R.id.btn_replace_fragment);

    btnFrag.setOnClickListener(new View.OnClickListener() {

        @Override

        public void onClick(View view) {

            addFragment(new Fragment2());
            Log.e("Replaced fragment", "2");
        }

    });
    replaceFragmentContent(new Fragment1());
}
protected void replaceFragmentContent(Fragment fragment) {

    if (fragment != null) {

        FragmentManager fmgr = getSupportFragmentManager();

        FragmentTransaction ft = fmgr.beginTransaction();

        ft.replace(R.id.container_body, fragment);

        ft.commit();

    }

}
protected void addFragment(Fragment fragment) {

    FragmentManager fmgr = getSupportFragmentManager();

    FragmentTransaction ft = fmgr.beginTransaction();

    ft.add(R.id.container_body, fragment);

    ft.addToBackStack(fragment.getClass().getSimpleName());

    ft.commit();

}

}

在fragment2布局xml文件中，将根布局设置为clickable="true"

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:clickable="true"
    android:background="#ffffff"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

1帧中的2个片段
