如何在屏幕顶部显示 admob?

How to show admob at the top of screen?

我正在尝试显示我自己网站的网页视图、admob 横幅和进度条。

在下面的代码中,webview 和进度条、admob 横幅一切正常。但是,admob 横幅显示在底部。

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

里面

com.google.android.gms.ads.AdView

添加 android:layout_alignParentTop="true" 并删除此 - android:layout_alignParentBottom="true"

在 Webview 中根据您的广告视图高度设置下边距

   android:layout_marginBottom="50dp"

在 AdView 中添加

android:layout_alignParentBottom="true"

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

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

这将强制您的布局向下延伸至底部,同时占用 adView 留下的剩余屏幕

      <ProgressBar
                    android:id="@+id/progress1" style="?

                    android:layout_alignParentBottom="true"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content" />

        </RelativeLayout>
    </LinearLayout>
</RelativeLayout>

使用约束布局
