Have you noticed that the Material guidelines specify that touch targets should sometimes be larger than the actual views?
Check out this dialog’s buttons, for example:
Since TouchDelegate is a bit clunky to use, ExtendedTouchView abstracts
it away and you can use plain ol’ XML to set those targets to any size, like
this:
<com.lnikkila.extendedtouchview.ExtendedTouchView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:touchHeight="48dp">
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button" />
</com.lnikkila.extendedtouchview.ExtendedTouchView>And that’s it!
You can get the compiled library on JCenter.
Throw this in your build.gradle:
compile 'com.lnikkila:extendedtouchview:0.1.0'ISC License (ISC)
