Question

我有一个RecyclerView，上面还有一个AdView。滚动RecyclerView时，我想将Adview保持在固定位置。我该怎么办？

这是我打开应用程序时的RecyclerView。

滚动RecyclerView

后

我正在使用FrameLayout，方法是单击以下打开的片段菜单：

frg = (Fragment)
ContainerFragment.newInstance(getString(R.string.DefaultGaleria), getString(R.string.DefaultFrase), getString(R.string.DefaultGif));

FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.popBackStackImmediate(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.replace(R.id.container, frg);
transaction.commit();

这是布局。

Answer 1

您可以使用RelativeLayout轻松地完成此操作，如下所示。

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

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clipToPadding="false"
        android:paddingTop="50dp" />

    <com.google.android.gms.ads.AdView
        android:id="@+id/adViewMob"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:background="@color/transparent"
        ads:adSize="SMART_BANNER"
        ads:adUnitId="@string/ad_unit_id" />
</RelativeLayout>

这应该达到您的目的。

Answer 2

将此代码放入您的xml文件中。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.google.android.gms.ads.AdView
        android:id="@+id/adViewMob"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/transparent"
        ads:adSize="SMART_BANNER"
        ads:adUnitId="@string/ad_unit_id" />

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_below="@+id/adViewMob"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>


</RelativeLayout>

滚动RecyclerView时，将AdView固定在顶部
