问题描述
我有一个xml文件,用于很多带有片段文件的活动,但是我的问题是我无法在工具栏中显示我想要的文本,我以这种方式使用该xml文件,因为我有一个导航抽屉,我需要处理某些事情,所以我必须那样做.
I have an xml that I use with so many activities with fragments file but my problem is that I can't display the text I want in the toolbar, I use that xml that way because I have a navigation drawer and I needed to handle somethings so I had to do it that way.
我的xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".StatusActivity"
android:orientation="vertical" >
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
style="@style/ToolBarStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="@dimen/abc_action_bar_default_height_material" />
</RelativeLayout>
我的活动之一:
public class GroupChatActivity extends ActionBarActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_base_layout);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
ActionBar actionBar = getSupportActionBar();
actionBar.setTitle("Groups history");
Aniways.init(this);
if(savedInstanceState == null)
{
FragmentManager manager = getSupportFragmentManager();
Fragment fragment = GroupChatFragment.newInstance(getIntent().getIntExtra("uid", 0));
manager.beginTransaction().add(R.id.frame_container, fragment).commit();
}
}
}
如您所见,我尝试将标题设置为操作栏,但这不起作用.
as you can see I try to set title to the action bar but it doesn't work.
推荐答案
getSupportActionBar().setDisplayShowTitleEnabled(true);
