Оставьте AdView закрепленным в верхней части при прокрутке RecyclerView

Question

У меня есть RecyclerView и выше этого, есть AdView.При прокрутке RecyclerView я бы хотел оставить Adview в фиксированном положении.Как я могу это сделать?

Вот мой RecyclerView при открытии приложения.

После прокрутки RecyclerView

Я использую FrameLayout, щелкая открытое меню фрагмента, как показано ниже:

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();

Вот макет.

Answer 1

вставьте этот код в ваш XML-файл ..

<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>

Answer 2

Вы можете сделать это легко, используя RelativeLayout, как показано ниже.

<?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>

Это должно служить вашей цели.
