android - Remove space between bounds and button border

Question

How do I remove those space between Button border and view bounds tried setting padding to 0dp but with no results.
These is material button with default style.

Answer 1

The MaterialButton has a default style with these insets:

 <style name="Widget.MaterialComponents.Button"..>
    <item name="android:insetLeft">0dp</item>
    <item name="android:insetRight">0dp</item>
    <item name="android:insetTop">@dimen/mtrl_btn_inset</item>
    <item name="android:insetBottom">@dimen/mtrl_btn_inset</item>
    ...
 </style>

The value of @dimen/mtrl_btn_inset is 6dp.

Just use:

  <com.google.android.material.button.MaterialButton
      android:insetTop="0dp"
      android:insetBottom="0dp"
      ../>
