Draw a frame around tap zone on the widget

I have a widget and I want to draw an orange frame around a tap zone on the widget. The frame should appear when a user tapped on the tap zone and disapper when the user releases his/her finger.

At this time I'm using separate layouts for each tap zone. Them works fine except the frame. I guess, I need to set

android:click开发者_JAVA技巧able="true"
android:focuseable="true"

for each layout. Also, I prepared a transparent shape drawable with orange border. But I can't find out what should I do next. How to draw the shape on the tap zone only while it's tapped?

I found the answer on my question here. I have no enough reputation to vote for abscondment's answer. So, could someone please to vote at his post? As about this question,

android:clickable="true"
android:focuseable="true"

attributes are not needed. I simple created a drawable:

<?xml version="1.0" encoding="UTF-8"?>
<selector
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:constantSize="true">
  <item android:state_pressed="true">
    <shape android:shape="rectangle">
      <corners android:radius="4dp" />
      <solid android:color="@android:color/transparent" />
      <stroke
        android:width="2dp"
        android:color="#eeffd700"
      />
    </shape>
  </item>
</selector>

and set the drawable as a background to my tap zones, like this:

<LinearLayout
  android:background="@drawable/selection_rectangle"
/>
