Here inside Toolbar inserted a textview with gravity = "center"
and disable default title by java.
Try with below code :
<android.support.design.widget.AppBarLayout
app:elevation="0dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<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/AppTheme.PopupOverlay" >
<TextView>
android:layout_width="wrap_content"
android:textSize="18dp"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="Title Here"
android:textColor="@color/white" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
java code disable your title :
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
solved How can I center the title of navigation drawer application?
