java - How to set the ActionBar title in middle instead of the default left aligned position?

Question

Trying to set the ActionBar title in middle instead of the default left aligned position. To do so, based on other answers this is what I've done:

    Toolbar myToolbar = (Toolbar) findViewById(R.id.toolbarDownloads);
    setSupportActionBar(myToolbar);
    if(getSupportActionBar()!=null)
    {
        getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
        getSupportActionBar().setCustomView(R.layout.actionbar_layout);
    }

actionbar_layout.xml

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout 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:text="Downloads"
        android:layout_centerInParent="true"
        android:textColor="#000000"
        android:id="@+id/mytext"
        android:textSize="18sp" />

</RelativeLayout>

However, this does not produce the intended result (ie this renders the text however still is left aligned), what's wrong with this approach and how to fix this?

Answer 1

try this use custom Toolbar

<android.support.v7.widget.Toolbar
    android:id="@+id/ar_toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    app:layout_scrollFlags="exitUntilCollapsed"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light">


    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="Center"
        android:orientation="vertical">

        <TextView
             android:id="@+id/toolbar_title"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center" />
    </LinearLayout>

</android.support.v7.widget.Toolbar>

now in java file

private Toolbar toolbar;
toolbar = (Toolbar) findViewById(R.id.ar_toolbar);
TextView mTitle = (TextView) toolbar.findViewById(R.id.toolbar_title);
 mTitle.setText("Nilesh Rathod");
setSupportActionBar(toolbar);
