如何使用 CoordinatorLayout 将 admob 横幅放在屏幕底部 [英] How to put admob banner to bottom of the screen using CoordinatorLayout

问题描述

I use CoordinatorLayout to make sliding tabs in activity_main.xml file. I want to put admob banner to bottom of the screen. But I have a problem, When I try to code below(activity_main.xml) Admob banner is shown of the top of the screen not bottom of the screen. In fact, I think this admob is shown bottom of the Toolbar(Seen in the picture). But I want to show bottom of the whole screen

       <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"
        xmlns:ads="http://schemas.android.com/tools"
        >

解决方案

try below mechanism.Put your viewpager and AdView inside RelativeLayout.

here is the sample layout file.

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <android.support.v7.widget.Toolbar
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

    </android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingTop="?actionBarSize">

    <android.support.v4.view.ViewPager
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/view_pager"
       >

    </android.support.v4.view.ViewPager>

    <com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true">

    </com.google.android.gms.ads.AdView>
</RelativeLayout>
