How to RelativeLayout Align Center android

<?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="match_parent"
android:orientation="vertical" >


    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="78dp"
        android:layout_marginTop="199dp"
        android:text="test" />

     <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView1"
        android:text="I want to align Center" />

</RelativeLayout>

Here is my xml code.

I want to use layout_alignCenter="@+id/textView1" in TextView2.

But there is no alignCenter.

I think layout_centerVertical or centerinParent also useless.

You could wrap a the RelativeLayout in a LinearLayout and use Space elements:

<LinearLayout layout_width="0dp" layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
    <Space
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"/>

    <RelativeLayout 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >


        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true"
            android:layout_marginLeft="78dp"
            android:layout_marginTop="199dp"
            android:text="test" />

         <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/textView1"
            android:text="I want to align Center" />

    </RelativeLayout>
    <Space
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"/>
</LinearLayout>

The Space element will distribute empty space relatively between all Space elements, based on the layout weights.

You wanted to show text view exact center of the screen....then use below modified code.

<?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="match_parent"
android:orientation="vertical" >

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:layout_centerInParent="true"
    android:text="test" />

 <TextView
    android:id="@+id/textView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/textView1"
    android:text="I want to align Center" 
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:layout_centerInParent="true"/>

</RelativeLayout>

This will definitely work for you. If there is any other requirement then explain in detail.
