使用导航抽屉在主活动中使用按钮切换活动

Question

我查了很多关于导航抽屉和按钮的问题，其中很多都是针对导航抽屉本身的按钮。我的问题是，我无法从具有导航抽屉的主活动中获取按钮移动到下一个活动。它会创建按钮但是点击器不会移动到以下活动，也不会举杯祝词让我知道点击器正在工作。

我使用了eclipse在您创建新导航抽屉时提供的模板。

public class UserMain extends Activity implements NavigationDrawerFragment.NavigationDrawerCallbacks {

Button one;

private NavigationDrawerFragment mNavigationDrawerFragment;

private CharSequence mTitle;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_user_main);

    one = (Button) findViewById(R.id.button1);
    System.out.println("Button1");
    one.setOnClickListener(new View.OnClickListener() {

        //There is a problem here!!!

        @Override
        public void onClick(View v) {

            System.out.println(v.toString());

            System.out.println("Button 1 pressed!");
            // TODO Auto-generated method stub

            Context context = getApplicationContext();
            CharSequence text = "ONE";
            int duration = Toast.LENGTH_SHORT;

            Toast passwordToast = Toast.makeText(context, text, duration);
            passwordToast.show();
        }
    });

    mNavigationDrawerFragment = (NavigationDrawerFragment) getFragmentManager()
            .findFragmentById(R.id.navigation_drawer);
    mTitle = getTitle();

    // Set up the drawer.
    mNavigationDrawerFragment.setUp(R.id.navigation_drawer,
            (DrawerLayout) findViewById(R.id.drawer_layout));
}

}
