如何設置可摺疊工具欄佈局中的重力頂部

Question

我面臨摺疊後的可摺疊工具欄中的一個問題，工具欄與tablayout重疊。如果我不滾動它工作正常，但如果我向上滾動它們都重疊，我正在動態改變片段中的工具欄摺疊模式。

代碼：

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(); 

    } 
}

試試這個代碼：

<android.support.design.widget.CoordinatorLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:fitsSystemWindows="true"> 
<android.support.design.widget.AppBarLayout 
    android:id="@+id/appbar" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    app:expanded="true" 
    android:fitsSystemWindows="true" 
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> 
    <android.support.v7.widget.Toolbar 
     android:id="@+id/toolbar" 
     android:layout_width="match_parent" 
     android:layout_height="?attr/actionBarSize" 
     app:popupTheme="@style/ThemeOverlay.AppCompat.Light" 
     app:layout_scrollFlags="scroll|enterAlways"> 
    </android.support.v7.widget.Toolbar> 
    <android.support.design.widget.TabLayout 
     android:id="@+id/tabs" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     app:tabTextColor="@android:color/white" 
     app:tabGravity="fill" 
     app:tabMode="scrollable" /> 
</android.support.design.widget.AppBarLayout>
