Why selector drawable doesn't work?

[vivekgupta4Git]

In sample app, we have state list drawable my_selector (In example MySelectorDecorator using this selector )

Inside of which, we have defined states when user select a date , it will decorate the drawable on selected date and remaining will be transparent but what if I want show drawable for rest but when selected make it transparent or different color?

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"
    android:exitFadeDuration="@android:integer/config_shortAnimTime">

  <item android:drawable="@drawable/ic_my_selector" android:state_checked="false"/>

  <item android:drawable="@drawable/ic_my_selector" android:state_pressed="false"/>

  <item android:drawable="@android:color/transparent" android:state_checked="true"/>

</selector>

the result is unexpected, it shows all dates are decorated and when we press on a date ,if it is transparent nothing will change but if we have used some different color says orange , it will blink orange for a milli sec and goes away. Why states aren't maintained? Am I missing something? How can I achieve the expected behavior?
