我删除了.TwoBase并将其替换为.Tutorial_1但是，当我点击主菜单上的第一个按钮（对于.Tutorial_1）时应用程序崩溃了，我仍然记录了这个日志来自Android Monitor：

此处打开.MainMenu
.Tutorial_1
public class MainMenu extends Activity {
Button button;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addListenerOnButton();
}
public void addListenerOnButton() {
final Context context = this;
button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, Tutorial_1.class);
startActivity(intent);
}
});
button = (Button) findViewById(R.id.button3);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, MainActivity.class);
startActivity(intent);
}
});
button = (Button) findViewById(R.id.button4);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, About.class);
startActivity(intent);
}
});
}
这是我替换为.Tutorial_1的{{1}}活动：
.TwoBase最后，这里是android清单：
public class Tutorial_1 extends Activity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.twobase_activity);
}
}
