将片段放在absoluteLayout中

Question

I have list of fragment containing buttons and one fragment, that shows up, after slide gesture is made ( similar to menu navigation drawer ). Problem is, that the buttonFragments always stay on top of my menuFragment.

Illustration:

I tried to use View.bringToFront() method, but it didnt work. Am I doing it wrong, or should I do it in different way?

Activity EditKeyboard.java:

public class EditKeyboard extends AppCompatActivity{

        ArrayList<Fragment> keyFragments; // buttons
        Fragment bMenu; // menu

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_edit_keyboard);

            createButtons();
            createBMenu();
        }


        public void createBMenu(){
            bMenu = ButtonMenuFragment.newInstance("a", "a");
            getFragmentManager().beginTransaction().add(R.id.edit_keyboard_layout,
                    bMenu, "bMenu").commit();
            View v = bMenu.getView();
            v.bringToFront(); // TODO bring menu to top
            ((View) v.getParent()).requestLayout();
            ((View) v.getParent()).invalidate();
            getFragmentManager().popBackStackImmediate("TAG", FragmentManager.POP_BACK_STACK_INCLUSIVE);
        }
    }

So what am I doing wrong?

Or should I use different layout (Relative or Frame one?)

Answer 1

I would use relativelayout.

<RelativeLayout>
     ...
     <fragment 
         android:name= "packagename.button_fragment"
         ...width, height, id, postion... />

     <fragment 
         android:name= "packagename.bMenu"
         ...width, height, id, postion... />

Here because bMenu is placed after button_fragment, it will be on top of button_fragment. So button_fragment is inflated first while rendering followed by bMenu putting it on top of it (subject of positioning being such).

我已经通过将每个按钮包装到FrameLayout中解决了它。
