Wie man Schwerkraftoberseite in zusammenklappbarem Werkzeugleistenlayout einstellt

Question

Ich stehe vor einem Problem in einer zusammenklappbaren Werkzeugleiste nach dem Zusammenklappen, Werkzeugleiste überlagert mit tablayout.Wenn ich nicht blättern, funktioniert es gut, aber wenn ich scrolle, sie beide überlappen, Ich ändere Toolbar-Kollapsmodus dynamisch in Fragmenten.

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(); 

    } 
}
