java - .IllegalStateException: ScrollView 只能承载一个直接子级

问题描述

我非常努力地理解 ScrollView 和 Linearlayout 并不断尝试在我的活动中使用，但我遇到了这个错误。我在滚动视图中已经只有一个 Linearlyout 并且其他孩子被包裹在高度和宽度的包裹内容中但是应用程序仍然崩溃..请帮助

解决方案

你需要像这样在 ScrollView 中只有一个孩子。

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<LinearLayout
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <ImageView ... />
    <TextView ... />
    <TextView ... />
    <TextView ... />

</LinearLayout>
</ScrollView>
