我正在使用Hello Android第3版作为指南创建我的第一个应用程序。第二章是关于制作数独应用程序的教程。当我从书中运行相同的代码时，它给出错误“Application Sudoku意外停止”。请帮忙。

确保您的layout文件main.xml中有一个标识为"continue_button"
View continueButton = findViewById(R.id.continue_button);
答案 1 :(得分：0)
你必须这样使用。
Button continueButton = (Button)findViewById(R.id.continue_button);
continueButton.setOnClickListener(this);
Button newButton = (Button)findViewById(R.id.new_button);
newButton.setOnClickListener(this);
Button aboutButton = (Button)findViewById(R.id.about_button);
aboutButton.setOnClickListener(this);
Button exitButton = (Button)findViewById(R.id.exit_button);
exitButton.setOnClickListener(this);
更改main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/background"
android:orientation="horizontal"
android:padding="30dip" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="vertical" >
将旧版LinearLayout更改为此版本。

在java文件中将continue_button替换为continue_label
编辑：在java文件中设置一个名为“main”的布局文件，但实际上它叫做“activity_main”
