Remove margin from Android buttons

Question

How can I remove the default margin Android buttons are using? I want the buttons to have full width (no space at all between the edge of the screen and the button) and no space between them. I am not setting any padding but they seem to have one.

I am using "Theme.AppCompat.Light.NoActionBar" as my app theme parent.

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">
    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

Tried them but they do not work as I wanted them. I ended using a custom ripple effect as background from here: http://stackoverflow.com/a/26349261/2456568 — netcyrax, Jul 13 '16 at 20:50

I had the same problem. The default button comes with margins. Set a button property like this:

android:layout_marginTop="-3dp"

Do the same for the left, right, and bottom margins. Or define a new drawable with these parameters:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    android:padding="10dp"
    >
    <solid android:color="@color/colorButtonGray"/>
    <corners
        android:bottomRightRadius="2dp"
        android:bottomLeftRadius="2dp"
        android:topLeftRadius="2dp"
        android:topRightRadius="2dp"/>
</shape>

The custom shape will not have any built in margins.

Use as below in the button xml, then change the other features this changes to how you want them displayed.

style="?android:attr/buttonBarButtonStyle"

That is used to remove padding, not margin. – LEE Sep 03 '17 at 05:18
