Android 显示AdMob横幅时调整布局

我正在我的

活动中集成AdMob横幅广告

。布局由

GridView

和

AdView

组成

我想要的：-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:weightSum="10"
    android:id="@+id/ll_gridmain"
    tools:context="mohits.app.picreddit.itemgrid">

<GridView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/gridview"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="9"
    android:divider="@null"
    android:numColumns="2"
    android:background="#454545" >
    </GridView>

<LinearLayout android:id="@+id/banner_view"
    android:orientation="horizontal"
    android:layout_height="0dp"
    android:layout_width="match_parent"
    android:layout_weight="1"
    android:layout_centerHorizontal="true"
    android:layout_alignParentBottom="true"
    android:gravity="bottom"
    android:visibility="gone">
<com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        ads:adSize="BANNER"
        ads:adUnitId="@string/ad_banner"
        android:visibility="gone">
    </com.google.android.gms.ads.AdView>

</LinearLayout>

</LinearLayout>

mAdView = (AdView) findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder()
        .addTestDevice("xxx")
        .build();
        mAdView.setAdListener(new AdListener() {
        @Override
        public void onAdLoaded() {
            super.onAdLoaded();
            mAdView.setVisibility(View.VISIBLE);
            bannerView.setVisibility(View.VISIBLE);
        }
    });

当广告未显示时，即开始或下载广告时，我希望

GridView

具有所有屏幕。但当广告被显示时，它应该覆盖下面所需的空间，但不要重叠任何内容

我的布局：-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:weightSum="10"
    android:id="@+id/ll_gridmain"
    tools:context="mohits.app.picreddit.itemgrid">

<GridView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/gridview"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="9"
    android:divider="@null"
    android:numColumns="2"
    android:background="#454545" >
    </GridView>

<LinearLayout android:id="@+id/banner_view"
    android:orientation="horizontal"
    android:layout_height="0dp"
    android:layout_width="match_parent"
    android:layout_weight="1"
    android:layout_centerHorizontal="true"
    android:layout_alignParentBottom="true"
    android:gravity="bottom"
    android:visibility="gone">
<com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        ads:adSize="BANNER"
        ads:adUnitId="@string/ad_banner"
        android:visibility="gone">
    </com.google.android.gms.ads.AdView>

</LinearLayout>

</LinearLayout>

mAdView = (AdView) findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder()
        .addTestDevice("xxx")
        .build();
        mAdView.setAdListener(new AdListener() {
        @Override
        public void onAdLoaded() {
            super.onAdLoaded();
            mAdView.setVisibility(View.VISIBLE);
            bannerView.setVisibility(View.VISIBLE);
        }
    });

我得到了什么：-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:weightSum="10"
    android:id="@+id/ll_gridmain"
    tools:context="mohits.app.picreddit.itemgrid">

<GridView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/gridview"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="9"
    android:divider="@null"
    android:numColumns="2"
    android:background="#454545" >
    </GridView>

<LinearLayout android:id="@+id/banner_view"
    android:orientation="horizontal"
    android:layout_height="0dp"
    android:layout_width="match_parent"
    android:layout_weight="1"
    android:layout_centerHorizontal="true"
    android:layout_alignParentBottom="true"
    android:gravity="bottom"
    android:visibility="gone">
<com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        ads:adSize="BANNER"
        ads:adUnitId="@string/ad_banner"
        android:visibility="gone">
    </com.google.android.gms.ads.AdView>

</LinearLayout>

</LinearLayout>

mAdView = (AdView) findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder()
        .addTestDevice("xxx")
        .build();
        mAdView.setAdListener(new AdListener() {
        @Override
        public void onAdLoaded() {
            super.onAdLoaded();
            mAdView.setVisibility(View.VISIBLE);
            bannerView.setVisibility(View.VISIBLE);
        }
    });

banner\u视图

布局始终显示，即使我将其设置为

GONE

。只有在显示广告时，此选项才可见

谢谢。

问题是，即使您删除了横幅，

GridView

的权重仍然是

9

，布局的

weightSum

是

10

，因此

GridView

不会填充整个

线性布局

从布局中删除以下行应该有效：

android:weightSum="10"

此外，设置
AdView
的可见性也是多余的

设置
视图组的可见性也会影响其子对象

您可以从
AdView
中删除以下属性：

android:visibility="gone"

之后，设置
横幅视图的可见性就足够了：

@Override
public void onAdLoaded() {
    super.onAdLoaded();
    bannerView.setVisibility(View.VISIBLE);
}
