我正在使用 Hello Android 3rd edition 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。当我运行书中相同的代码时，它会给出错误“应用程序数独已意外停止”。请帮助。

确保layout文件main.xml中有一个具有 id的按钮"continue_button"

View continueButton = findViewById(R.id.continue_button);

你必须使用这种方式。

          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);

改变你的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" >

用你的旧换LinearLayout这个。

用 java 文件中的 continue_label 替换 continue_button

编辑：在 java 文件中，您设置了一个名为“main”的布局文件，但实际上它被称为“activity_main”
