我想在导航栏中设置标题。在我的应用程序中我创建了一个导航抽屉它正在工作但是当我试图设置标题时标题名称没有显示在标题栏中不知道为什么？
我尝试了很多教程，但没有人正在工作，不知道错误在哪里。
我在其他活动中尝试过这种方式，如： -
getActivity().setTitle("Home");
但没有工作..在这里我发布我的完整代码： -
public class MainActivity extends AppCompatActivity {
DrawerLayout mDrawerLayout;
NavigationView mNavigationView;
FragmentManager mFragmentManager;
FragmentTransaction mFragmentTransaction;
SessionManager session;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);//will hide the title not the title bar
setContentView(R.layout.activity_main);
session = new SessionManager(getApplicationContext());
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mNavigationView = (NavigationView) findViewById(R.id.shitstuff);
//*//**
// * Lets inflate the very first fragment
// * Here , we are inflating the TabFragment as the first Fragment
// *//*
//Intent intent = new Intent(getApplicationContext(),MainActivity.class);
//startActivity(intent);
mFragmentManager = getSupportFragmentManager();
mFragmentTransaction = mFragmentManager.beginTransaction();
mFragmentTransaction.replace(R.id.containerView, new TabFragment()).commit();
// * Setup click events on the Navigation View Items.
//*
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
mDrawerLayout.closeDrawers();
if (menuItem.getItemId() == R.id.nav_home) {
FragmentTransaction fragmentTransaction = mFragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.containerView, new TabFragment()).commit();
}
return false;
}
});
//Setup Drawer Toggle of the Toolbar
android.support.v7.widget.Toolbar toolbar = (android.support.v7.widget.Toolbar) findViewById(R.id.toolbar);
ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.app_name,
R.string.app_name);
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();
}
}

这里我发布了导航抽屉的完整代码，请告诉我如何在标题栏上设置标题名称。
答案 0 :(得分：3)
尝试以下代码，希望它可以解决您的问题：
1 - 在您的xml文件中，输入此代码
<android.support.v7.widget.Toolbar xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:layout_below="@+id/main_header"
android:background="@color/white"
android:contentInsetLeft="0dp"
android:contentInsetStart="0dp"
android:title=""
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:navigationIcon="@mipmap/menu_icon"
app:title=""/>
2 - 在您的代码中，放在代码
下面public static Toolbar mToolbar;
mToolbar = (Toolbar) findViewById(R.id.main_toolbar);
3 - 现在当您从navigationDrawer打开任何片段时，在工具栏中设置标题如下
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
//Checking if the item is in checked state or not, if not make it in checked state
if (menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);
//Closing drawer on item click
drawerLayout.closeDrawers();
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId()) {
case R.id.drawer_new_sale:
mToolbar.setTitle(getString(R.string.dashboard_new_sale));
return true;
case R.id.drawer_recent_sales:
mToolbar.setTitle(getString(R.string.dashboard_recent_sales));
return true;
}
}

Try this code in your activity class
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("Home");
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
