设置工具栏的重力（RelativeLayout）

Question

i need to set Gravity programmatically to Bottom. It's loks like the default value is Top.The attributes in the Comment specifically for the Toolbar on this Fragment. My Idea is to add the chances on onCreateView and remove onDetach.

private Toolbar toolbar;
private ViewGroup.LayoutParams params;

 RelativeLayout.LayoutParams newParams = new
 RelativeLayout.LayoutParams(toolbar.getLayoutParams());
 params = new RelativeLayout.LayoutParams(toolbar.getLayoutParams());
 newParams.height = dpToPx(128);
 //need to set gravity
 toolbar.setPadding(0, 0, 0, dpToPx(28));

 toolbar.setLayoutParams(newParams);

 /*android:layout_height="128dp"
   android:gravity="bottom""
   android:paddingBottom="28dp"*/

Thanks

Answer 1

To move one of the toolbar controls to the bottom of the toolbar, don't set the layout parameters on the toolbar itself. You need to set the gravity of the view you are trying to move:

control.setGravity(Gravity.BOTTOM);

Answer 2

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/primary"
    android:minHeight="?attr/actionBarSize"
    android:gravity="bottom"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>

First with android:gravity="bottom"
