Question

我正在尝试显示自己网站的webview，admob横幅和进度条。

在下面的代码，webview和进度栏中，admob横幅显示一切正常。但是，admob横幅显示在底部。

如何在屏幕顶部显示admob标语？我试图将adview移到底部，但显示空白屏幕。

Answer 2

内部

com.google.android.gms.ads.AdView

添加android:layout_alignParentTop="true"并将其删除-android:layout_alignParentBottom="true"

Answer 3

在Webview中，根据您的广告浏览高度设置底边距

   android:layout_marginBottom="50dp"

在AdView中添加

android:layout_alignParentBottom="true"

Answer 4

将您的父母RelativeLayout更改为LinearLayout并将其添加到内部LinearLayout

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

这将迫使您的布局向下扩展到底部，同时占用adView剩下的剩余屏幕

Answer 5

如果要在屏幕顶部显示广告横幅，则应使用

android:layout_alignParentTop="true"

代替

android:layout_alignParentBottom="true"

Answer 6

使用约束布局

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"

    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.myapp.MainActivity">

    <com.google.android.gms.ads.AdView xmlns:ads="http://schemas.android.com/apk/res-auto"
        android:id="@+id/adView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        ads:adSize="SMART_BANNER"
        ads:adUnitId="ca-app-pub-3940256099942544/6300978111"/>

    <WebView
        android:id="@+id/activity_main_webview"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintTop_toBottomOf="@id/adView"
        app:layout_constraintBottom_toBottomOf="parent"/>

    <ProgressBar
        android:id="@+id/progress1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toBottomOf="@id/adView"
