Answer 1

将高度设置为match_parent并添加android:fillViewport元素

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="10dp"
    android:fillViewport="true"/>
    ...
    ...
</android.support.v4.widget.NestedScrollView>

Answer 2

添加

android:windowSoftInputTypeMode="adjustResize|stateAlwaysHidden"    to activity in your manifest, then make your nestedtscrollview height match parent and fillviewport true in the xml

Answer 3

尝试将android:minHeight 添加到您的CollapsingToolbarLayout
