に変更できません.MapViewの高さを変更することはできません。 私が話していること：MapViewの高さを
fragment_map_view.xmlはmain_activity.xml viewpagerであるfragment_main_view.xmlです。
fragment_map_view.xml：
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent">
<com.google.android.gms.maps.MapView
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</ScrollView>
fragment_main_view.xml：
