How to center a Custom View on Android?

Question

I am trying to center the view for different resolutions using the layout, and gravity properties, but it's not working. Is there a way to make the custom view center horizontally across different resolutions?

Do I need to do something on the onMeasure method ?

Here is one of the things I am trying right now, the view is to the left of the center..

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <RelativeLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="50dp"
        android:gravity="center_horizontal">

        <com.application.app.ui.CustomView
            android:id="@+id/ivCoinAnimation"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"/>


    </RelativeLayout>


</FrameLayout>

Assuming you have a View inside a layout like FrameLayout, you would set View's layout_gravity to center. Don't mix it up with gravity!

Also, it may indeed be necessary to override onMeasure(). Read it's documentation to decide if you need to override it. If you do, be aware that the parameters are encoded with View.MeasureSpec.
