android - AdView doesn't show ads at the bottom of the linear layout layout -Why So?

问题描述

I'm trying to show admob adview at the bottom of the screen but it doesn't work. It shows ad below the text if the text is short (doesn't need to scroll) , but if the text is long (need to scroll) the adview doesn't show at all. I want to show the adview at the bottom of my screen no matter how long or short the text is. I have been at this for hours but couldn't figure out to make it work.

Here is my Activity.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

        android:background="@color/backgroundColor">

        <TextView

            android:contentDescription="@string/text_to_speech"

解决方案

添加一个新属性android:layout_weight="1" 并修改滚动视图的高度，如下所示。

    android:layout_height="0dp"
    android:layout_weight="1"

所以滚动视图的最终属性集看起来像，

<ScrollView
    android:id="@+id/scrollView"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1">
