Question

我有一个活动，我设置了一个工具栏。

MainActivity.class

@ContentView(R.layout.activity_main)
public class MainActivity extends RoboActionBarActivity {

    @InjectView(R.id.tool_bar)
    Toolbar toolbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setToolBar();

        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .add(R.id.container, new SplashFragment())
                    .commit();
        } else {
            getSupportFragmentManager().beginTransaction()
                    .replace(R.id.container, new HomeFragment())
                    .commit();
        }
    }

    private void setToolBar() {
        setSupportActionBar(toolbar);
    }
 }

activity_main.xml中

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

</android.support.v7.widget.Toolbar>

当我去 HomeFragment.class 时一切正常。现在，当我从 HomeFragment.class 转移到 InfoFragment.class 时，我想更改我的工具栏。

InfoFragmnet.class

public class InfoFragment extends RoboFragment {


    @InjectView(R.id.menuItemStores)
    LinearLayout menuItemStores;
    @InjectView(R.id.menuItemInsurance)
    LinearLayout menuItemInsurance;
@InjectView(R.id.menuItemWishlist)
LinearLayout menuItemWishlist;
@InjectView(R.id.menuItemAccount)
LinearLayout menuItemAccount;


public InfoFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_info, container, false);
    return rootView;
}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
        setupUIElements();
    }
}

这里我被阻止了，并没有找到如何更改工具栏并覆盖工具栏中项目的点击事件。

Answer 1

如果您想更改工具栏的标题，只需致电toolbar.setTitle(xxx) 如果要更改选项菜单，请更新选项菜单资源并调用invalidateOptionsMenu();

希望这会对你有所帮助。
