不，你在LinearLayout中有一个ScrollView。您的ScrollView中只有一堆文本视图。把它改成这个：

<LinearLayout

        tools:context=".Blood">

    <TextView

你需要像ScrollView一样只有一个孩子。

<?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>
