Android垂直ScrollView根本不起作用

Question

我一直坚持这个问题调整android:layout_height/width很多，但我似乎无法理解为什么它不起作用。我查了更多类似我的问题，但那些似乎对我不起作用。

Answer 1

您可能想在添加名称空间xmlns后尝试：android =＆＃34; http：//schemas.android.com/apk/res/android"到ScrollView。

Answer 2

尝试实施TextViews或其他任何内容：

<android.support.v4.widget.NestedScrollView
        android:id="@+id/scroll"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:clipToPadding="false"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"

       <!-- your content -->

</android.support.v4.widget.NestedScrollView>

或使用您的代码，类似这样的内容：

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
