============ Problem Description ============
According to the tutorial, it generated a framework of its own problems!!! It's so ... Ask the great God to answer!
The code is as follows: (Mainactivity.java)
Package com.example.hello1;
Import android.support.v7.app.ActionBarActivity;
Import Android.os.Bundle;
Import Android.view.Menu;
Import Android.view.MenuItem;
public class Mainactivity extends Actionbaractivity {
@Override
protected void OnCreate (Bundle savedinstancestate) {
Super.oncreate (savedinstancestate);
Setcontentview (R.layout.activity_main);
}
@Override
public boolean Oncreateoptionsmenu (Menu menu) {
Inflate the menu; This adds items to the action bar if it is present.
Getmenuinflater (). Inflate (R.menu.main, menu);
return true;
}
@Override
public boolean onoptionsitemselected (MenuItem item) {
Handle Action Bar Item clicks here. The Action Bar would
Automatically handle clicks on the Home/up button, so long
As you specify a the parent activity in Androidmanifest.xml.
int id = item.getitemid ();
if (id = = r.id.action_settings) {
return true;
}
return super.onoptionsitemselected (item);
}
}
Logcat error is as follows:
