Android Xml 布局问题导致 textView 下移

Question

我不知道为什么布局设计在模拟器上看起来是正确的。 请检查屏幕截图和代码。几乎就像有东西在其他东西上面一样，导致工具栏和文本视图向下移动一点。我尝试一遍又一遍地更改或删除这些元素，但没有运气。任何帮助将不胜感激

谢谢你。

考虑将

android:fitsSystemWindows="true"

添加到根布局。或到你的根

theme

<androidx.constraintlayout.widget.ConstraintLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:background="@color/BackGround"
tools:context=".ReportError">

适合系统Windows

它设置视图的填充以确保内容不会重叠 系统窗口。
