我正在制作应用程序，并将数据放入mysql。当我的同学在她的笔记本电脑上运行该项目时，这没关系。但这在我的笔记本电脑中不起作用。我正在尝试解决问题，但是该应用程序仍然停止。我不知道为什么
这是代码和日志

你可以去你MainActivity，向下滚动到的setContentView说，部分解决这个问题（R.layout。your_layout_name）; 并在按住Ctrl（Windows）或Cmd（Mac）的同时单击your_layout_name。这将带您到布局文件。在这里，您应该在开始处看到一个ScrollView开头标签，在结尾处看到一个结束标签。只需将其更改为以下形式：
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:text="This is your first item"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<TextView
android:text="This is your second item"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<TextView
android:text="This is your third item"
android:layout_width="match_parent"
