FrameLayout n'apparaît pas dans la vue texte

Question

J'essaie de créer un RelativeLayout dynamiquement mais pour une raison quelconque, la vue personnalisée est dessinée en haut de la vue de texte. Est-ce que quelqu'un sait ce qui ne va pas et comment placer la vue du texte au-dessus du dessin?

public class MyRLayout extends android.support.v4.app.Fragment { 

    public MyRLayout() {} 

    @Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 

     return inflater.inflate(R.layout.my_relativelayout, container, false); 
    } 

    @Override 
    public void onActivityCreated(@Nullable Bundle savedInstanceState) { 
     View v = getView(); 
     assert v != null; 

     RelativeLayout relativelayout = v.findViewById(RelativeLayout_custom); 

     RelativeLayout.LayoutParams rlp1 = new RelativeLayout.LayoutParams(GridLayout.LayoutParams.MATCH_PARENT, GridLayout.LayoutParams.WRAP_CONTENT); 
     RelativeLayout.LayoutParams paramsP1 = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.WRAP_CONTENT); 

     // add text view 
     TextView tv1 = new TextView(getActivity()); 
     tv1.setText("Hello World"); 
     TextViewCompat.setTextAppearance(tv1, android.R.style.TextAppearance_Medium); 
     tv1.setTextColor(Color.WHITE); 
     tv1.setGravity(Gravity.CENTER); 

     // set view for drawing1 
     FrameLayout frameLayoutP1 = new FrameLayout(getActivity()); 
     paramsP1.height = fortyDp; 
     Drawing1 cvDrawing1 = new Drawing1(getActivity()); 
     cvDrawing1.setLayoutParams(paramsP1); 
     frameLayoutP1.addView(cvDrawing1); 

     // generate IDs for views 
     tv1.setId(View.generateViewId()); 
     frameLayoutP1.setId(View.generateViewId()); 

     // set RelativeLayout rules for views 
     paramsP1.addRule(RelativeLayout.BELOW, tv1.getId()); 

     // setLayoutParams for views 
     tv1.setLayoutParams(rlp1); 

     // add views to RelativeLayout 
     relativelayout.addView(tv1); 
     relativelayout.addView(frameLayoutP1); 

     super.onActivityCreated(savedInstanceState); 
    } 
} 

Answer 1

tv1.setLayoutParams(rlp1); 

devrait être

tv1.setLayoutParams(paramsP1); 

(celui que vous avez ajouté la règle ci-dessous pour)

vous configurez les mauvaises LayoutParams.
