我试图调试我的菜单活动,但它似乎无法显示输出。屏幕上的错误消息显示 Savings Guider(我的应用程序名称)已停止工作。如果我从 android 菜单中手动单击我的应用程序,它会说我的应用程序没有安装。但是,我的代码中没有错误。任何人都可以帮助我吗?
我的菜单活动代码:
public class SavingsGuiderMenuActivity extends SavingsActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
ListView menuList = (ListView) findViewById(R.id.ListView_Menu);
String[] items = { getResources().getString(R.string.start),
getResources().getString(R.string.about),
getResources().getString(R.string.help) };
ArrayAdapter<String> adapt = new ArrayAdapter<String>(this, R.layout.menu_item, items);
menuList.setAdapter(adapt);
menuList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View itemClicked, int position, long id) {
// Note: if the list was built "by hand" the id could be used.
// As-is, though, each item has the same id
TextView textView = (TextView) itemClicked;
String strText = textView.getText().toString();
if (strText.equalsIgnoreCase(getResources().getString(R.string.start))) {
// Launch the app Activity
startActivity(new Intent(SavingsGuiderMenuActivity.this, SavingsGuiderAppActivity.class));
} else if (strText.equalsIgnoreCase(getResources().getString(R.string.help))) {
// Launch the Help Activity
startActivity(new Intent(SavingsGuiderMenuActivity.this, SavingsGuiderHelpActivity.class));
} else if (strText.equalsIgnoreCase(getResources().getString(R.string.about))) {
// Launch the about Activity
startActivity(new Intent(SavingsGuiderMenuActivity.this, SavingsGuiderAboutActivity.class));
}
}
});
}
}
我的清单:
