Can you center a Button in RelativeLayout?

Question

I\'m trying to center a button in relative layout, is this possible? I\'ve tried the Gravity and Orientation functions but they don\'t do anything.

Answer 1

Try

android:layout_centerHorizontal="true"

Exactly like this, it works for me:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:background="#ff0000">

    <Button
        android:id="@+id/btn_mybutton"
        android:layout_height="wrap_content"
        android:layout_width="124dip"
        android:layout_marginTop="5dip"
        android:layout_centerHorizontal="true"/>

</RelativeLayout>

Answer 2

Removing any alignment like android:layout_alignParentStart="true" and adding centerInParent worked for me. If the "align" stays in, the centerInParent doesn't work

Answer 3

It's really easy. Try the code below,

<RelativeLayout
    android:id="@+id/second_RL"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/first_RL"
    android:background="@android:color/holo_blue_bright"
    android:gravity="center">

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button" />

</RelativeLayout>

Answer 4

Its easy, dont Align it to anything

<Button
        android:id="@+id/the_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" 
        android:layout_centerInParent="true"
        android:text="Centered Button"/>

Answer 5

You can use CENTER_IN_PARENT for relative layout.

Add android:layout_centerInParent="true" to element which you want to center in the RelativeLayout

Answer 6

To center align in one of the direction use android:layout_centerHorizontal="true" or android:layout_centerVertical="true" in the child layout
