Also habe ich im Symbolleistenlayout eine Werkzeugleiste, die oben hängt. Es sollte eine Symbolleiste geben, unter der sich ein Pager befindet. Ich bin nicht in der Lage, herauszufinden, warum. Wenn es ein dummer Fehler ist, verzeih mir. Ich bin neu bei Android.

My Activity XML-Datei //////////////////////////////////// ///////////////////////

<android.support.design.widget.AppBarLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:theme="@style/AppTheme.AppBarOverlay"> 
<android.support.v7.widget.Toolbar 
    android:id="@+id/toolbar" 
    android:layout_width="match_parent" 
    android:layout_height="65dp" 
    android:background="?attr/colorPrimary" 
    app:popupTheme="@style/AppTheme.PopupOverlay" /> 

</android.support.design.widget.AppBarLayout> 

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/frame_replace" 
    android:layout_below="@+id/toolbar"> 

</FrameLayout> 
    </android.support.design.widget.CoordinatorLayout> 

////////////////// ////////////////////////////////////////////////// Ich ersetze die Rahmenlayout mit Fragment. Die Symbolleiste in meiner Aktivität wird nach dem Zurückdrücken des Fragments durch die Fragmentsymbolleiste ersetzt. Ich hoffe, dass dies hilft, mein Problem klarer zu erklären.

android: fitsSystemWindows = "true" fügen Sie diese Zeile in Ihrer Stammansicht hinzu.
