I set ViewPager's height wrap_content but it doesn't work. I tried answers in other similar questions but they didn't solve my problem. my activity_main code is this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#C49A1544"
tools:context=".MainActivity">
<include layout="@layout/toolbar"
android:id="@+id/main_toolbar"/>
<androidx.viewpager.widget.ViewPager
android:id="@+id/viewpager"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="@dimen/standard_margin_x2"
android:layout_below="@id/main_toolbar"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true" />
</RelativeLayout>
