如何在FragmentActivity上设置工具栏？

Question

我想在我的活动上设置工具栏,扩展FragmentActivity.我知道使用setSuppoertActionBar(toolbar)方法,我们扩展AppCompatActivity代替FragmentActivity,但我重写onMenuItemSelected(int featureId, MenuItem item)这是最后的方法AppCompatActivity和最终方法不能覆盖.所以我被限制延伸FragmentActivity.

这是我的代码:

public class MainActivity extends FragmentActivity
{
    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);   -> error is here
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) 
    {
       // Inflate the menu
       getMenuInflater().inflate(R.menu.menu_main, menu);
       return true;
    }

    @Override
    public boolean onMenuItemSelected(int featureId, MenuItem item) {
        switch(item.getItemId()){
            case R.id.action_search:
                onSearchRequested();
                break;
        }
        return super.onMenuItemSelected(featureId, item);
    }

我看到了许多与该问题相关的答案,但每个人都说延伸AppCompatActivity而不是FragmentActivity但我想设置工具栏以及覆盖onMenuItemSelected(int featureId, MenuItem item)方法.

我该怎么办,请帮忙.

当你使用时,这个东西很好NavigationDrawer 用: -

 toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayShowTitleEnabled(false);

然后根据不同标题设置工具栏标题onNavigationItemSelected: -

@Override
    public boolean onNavigationItemSelected(MenuItem item) {
        // Handle navigation view item clicks here.

        sfm = getSupportFragmentManager();
        Fragment fragment = new Fragment();
        int id = item.getItemId();

        if (id == R.id.nav_id) {
            fragment = new YourFragment();
            toolbar.setTitle("SET TOOLBAR NAME");
        }else if (id == R.id.nav_id2) {
            fragment = new YourFragment();
            toolbar.setTitle("SET TOOLBAR NAME");
        } 

对于单个片段,首先要自定义style.xml如下: -

<style name="YourStyleName" parent="Theme.AppCompat.Light.DarkActionBar">
// ToDo as you want to do or as per your requirement

</style>

然后申请到您的自定义toolbar: -

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    app:popupTheme="@style/YourStyleName" >

  // ...........


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