I'm new at Android programming so I don't know all the features. As I understood, all generated activities has a title bar which contains app_name string resource. I managed to change title of sole activity but I don't understand how to change alignment of the text of the title. I mean, the're generated like this:
but I need it to be like this:
If you are using support toolbar , the approach will be easy. just add a text view inside it and make it centered :
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar_top"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="@color/action_bar_bkgnd"
app:theme="@style/ToolBarTheme" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Toolbar Title"
android:layout_gravity="center"
android:id="@+id/toolbar_title" />
</android.support.v7.widget.Toolbar>
in your activity you can access the title like so:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_top);
TextView Title = (TextView) toolbar.findViewById(R.id.toolbar_title);
To have a centered title in ABS (if you want to have this in the default ActionBar, just remove the "support" in the method names), you could just do this:
In your Activity, in your onCreate()
method:
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(R.layout.abs_layout);
xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="my Title"
android:textColor="#ffffff"
android:id="@+id/mytext"
android:textSize="18sp" />
</LinearLayout>
Now you should have an Actionbar with just a title. If you want to set a custom background, set it in the Layout above (but then don't forget to set android:layout_height="match_parent").
