Android - Center the title of the Toolbar [duplicate]

Question

i have a Toolbar in my app like that:

<?xml version="1.0" encoding="utf-8"?> <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" xmlns:local="http://schemas.android.com/apk/res-auto" android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:minHeight="?attr/actionBarSize" android:background="#263355" local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" local:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

And i add the title as that:

getSupportActionBar().setTitle(title);

I've read that Android toolbar center title and custom font

But if i change the xml of the toolbar, i don't know how to change the value of the TextView. Someone can help me ?

Use that other answer, and use findViewById to get the TextView — Knossos

Do not use getSupportActionBar().setTitle(title); to set the title, if you have a custom Toolbar layout.

Instead, assuming your XML layout looks like this:

 <!-- Toolbar --> <android.support.v7.widget.Toolbar android:id="@+id/main_toolbar" android:layout_width="match_parent" android:layout_height="wrap_content"> <LinearLayout android:id="@+id/main_toolbar_layout" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:orientation="vertical"> <TextView android:id="@+id/main_toolbar_title" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> </android.support.v7.widget.Toolbar>

You need to call, somewhere in your MainActivity's onCreate() probably:

((TextView) findViewById(R.id.main_toolbar_title)).setText("Title!");
