ActionBar - setTitle seems to not to be called. All other things I'm doing with ActionBar (like HomeIsUp and so on) are going well, but setTitle - not.
Here is the code of a simple activity:
public class GuidelineDetails extends Activity implements OnClickListener {
String guideline_name;
String guideline_attachment;
public static TextView tv_title;
public static TextView tv_intro;
public static TextView tv_test;
public static WebView webview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.guideline_detail);
getActionBar().setTitle("Privet");
getActionBar().setHomeButtonEnabled(true);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setDisplayShowTitleEnabled(false);
getActionBar().setIcon(R.drawable.listbullet);
///// some code
}
}
Why does it not set the title?
in manifest:
<activity
android:name=".GuidelineDetails"
android:configChanges="orientation"
android:label="Guideline"
android:screenOrientation="portrait"
android:theme="@android:style/Theme.Holo.Light" >
</activity>
in layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout

<TextView

</TableRow>

android:layout_width="match_parent"

</TableRow>

To generate ActionBar icons, be sure to use the Asset Studio in Android Studio. To create a new Android icon set, right click on a res/drawable folder and invoke New -> Image Asset.
To add actions to the action bar, create a new XML file in your project's res/menu/ directory. The app:showAsAction attribute specifies whether the action should be shown as a button on the app bar.
The app bar, also known as the action bar, is one of the most important design elements in your app's activities, because it provides a visual structure and interactive elements that are familiar to users.
because of
getActionBar().setDisplayShowTitleEnabled(false);
change it to
getActionBar().setDisplayShowTitleEnabled(true);
