如何在FragmentActivity上设置工具栏?

问题描述

我想在扩展 FragmentActivity 的活动上设置工具栏.我知道，对于使用setSuppoertActionBar(toolbar)方法，我们扩展了AppCompatActivity而不是FragmentActivity，但是我覆盖了onMenuItemSelected(int featureId, MenuItem item)方法，该方法在AppCompatActivity中是最终的，并且final方法无法覆盖.所以我只能扩展FragmentActivity.

I want to set toolbar on my activity which extends FragmentActivity. I know that for use setSuppoertActionBar(toolbar) method we extends AppCompatActivity instead of FragmentActivity but I override the onMenuItemSelected(int featureId, MenuItem item) method which is final in AppCompatActivity and final method cannot override. so I'm restricted to extends 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);
    }

我看到了很多与此问题相关的答案，但每个人都说扩展了AppCompatActivity而不是FragmentActivity，但是我想设置工具栏以及覆盖onMenuItemSelected(int featureId, MenuItem item)方法.

I saw many answers related to that question but everyone says extends AppCompatActivity instead of FragmentActivity but I want to set toolbar as well as override onMenuItemSelected(int featureId, MenuItem item) method.

我该怎么办，请帮忙.

推荐答案

当您使用NavigationDrawer 时，这东西很好使用此:-

This thing is good when you are using NavigationDraweruse this:-

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

然后根据onNavigationItemSelected 中的具有不同标题的不同片段设置工具栏标题:-

then set Toolbar Title according to different fragment with different Titles in 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，首先像这样自定义style.xml:-

For single fragment, first customize your style.xml like this :-

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

</style>

然后将其应用于您的自定义toolbar:-

then apply into your custom 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>
