我刚开始使用 android，我有我的 MainActivity 类，其中有一个 void 'addItem'，每次我删除应用程序强制关闭的 void 时我想移动到不同的类
如何在不干扰应用程序运行的情况下消除空白？我已经搜索了项目的路径，但找不到任何对它的引用，所以我不知道为什么它不起作用。
如果有帮助，我在 Windows 7 上使用 IntelliJ
*更新*
更详细一点，目前应用程序中没有太多内容；这是ActivityMain：
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
public class ActivityMain extends Activity {
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_main, menu);
return true;
}
public void addItem(MenuItem menuItem) {
}
我创建了另一个类，其中将有 addItem void，但是当我从这里删除它并尝试运行应用程序时它会停止
这是logcat错误
