android - I want to change actionbar icon size

Question

I tried to use this code

<item
        android:id="@+id/male_button"
        android:layout_width="46dp"
        android:layout_height="56dp"
        android:layout_gravity="right"
        android:icon="@drawable/icon_male"
        android:showAsAction="always"
        android:title="i"/>
    <item
        android:id="@+id/female_button"
        android:layout_width="46dp"
        android:layout_height="56dp"
        android:layout_gravity="right"
        android:icon="@drawable/icon_female"
        android:showAsAction="always"
        android:title="i"/>

and I changed android:layout_width="46dp" to android:layout_width="30dp" but I still have the same size the desired image is

and I now have this

How can I change the icons to be as the first picture ?

Answer 1

To reduce the space between actions icons, in your styles.xml you need to create a actionButtonStyle and referencing it your main theme (ex: "AppTheme").

1st step (put the two sentences):

<style name="AppTheme" parent="Theme.AppCompat.Light">
  ...
  <item name="android:actionButtonStyle">@style/myActionButtonStyle</item>
  <item name="actionButtonStyle">@style/myActionButtonStyle</item>
  ...
</style>

2nd step (the parameter "android:width" is the great secret):

<style name="myActionButtonStyle" parent="Widget.AppCompat.ActionButton">
    <item name="android:minWidth">30dp</item>
    <item name="android:maxWidth">48dp</item>
    <item name="android:width">38dp</item>
</style>
