Comment faire pour placer la gravité en haut dans la barre d'outils pliable

Question

Je suis confronté à un problème dans une barre d'outils pliable après l'effondrement, barre d'outils se superpose avec tablayout.Si je ne défile pas, il fonctionne bien mais si je défile, ils se chevauchent Je modifie dynamiquement le mode de réduction de la barre d'outils en fragments.

Code:

private void setToolbarPin(Toolbar toolbar) 
    { 

     ViewGroup.LayoutParams params = toolbar.getLayoutParams(); 
     CollapsingToolbarLayout.LayoutParams newParams; 
     if (params instanceof CollapsingToolbarLayout.LayoutParams) { 
      newParams = (CollapsingToolbarLayout.LayoutParams)params; 
     } else { 
      newParams = new CollapsingToolbarLayout.LayoutParams(params); 
     } 

     newParams.setCollapseMode(CollapsingToolbarLayout.LayoutParams.COLLAPSE_MODE_OFF); 
     newParams.gravity = Gravity.TOP; 
     toolbar.setLayoutParams(newParams); 






     // toolbar.requestLayout(); 

    } 
}
