在菜单中重复
关于重复菜单，请帮助我。
头等舱：
public class A extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.settings:
Intent intent = new Intent(this, ShowSettings.class);
startActivity(intent);
break;
case R.id.services:
Intent intent2 = new Intent(this, Test.class);
startActivity(intent2);
break;
case R.id.Quit:
finish();
break;
default:
break;
}
return true;
}
}
第二课
public class Test extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
over here i will be fetching the list from the server
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.settings:
Intent intent = new Intent(this, ShowSettings.class);
startActivity(intent);
break;
case R.id.services:
Intent intent2 = new Intent(this, Test.class);
startActivity(intent2);
break;
case R.id.Quit:
finish();
break;
default:
break;
}
return true;
}
}
我已经尝试了in this way但它没有用。

而不是模拟器当我试图在Android上运行时我得到了以下logcat 
1 个答案:
答案 0 :(得分：0)
我只尝试了您提到的link中提供的代码的onCreateOptionsMenu方法，但它确实有效。
从代码（仍然来自链接，MenuHandler.java）
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.settings:
Intent intent = new Intent(this, ShowSettings.class);
startActivity(intent);
break;
case R.id.services:
Intent intent2 = new Intent(this, Test.class);
startActivity(intent2);
break;
case R.id.Quit:
确保将新活动称为
Intent intent = new Intent(activity, ShowSettings.class);
activity.startActivity(intent);
case R.id.services
