ImageRadioButton.java

/**
 * 
 * Android radio button that draws (state list) drawable to immediate left of its text. 
 * RadioButton has an attribute drawableLeft or drawableStart, however those 
 * draw the drawable to the left of the component and does not center align 
 * with the text itself.
 * 
 * This ui component also supports statelistdrawables and state changes on 
 * the drawable.
 * 
 * It is possible to create a custom layout for such cases, but then it becomes 
 * cumbersome to use RadioGroup since it has instance checks for RadioButton 
 * 
 * <com.github.siyamed.gist.ImageRadioButton
 *   android:layout_width="match_parent"
 *   android:layout_height="wrap_content"
 *   android:gravity="center"
 *   android:button="@null"
 *   android:text="RadioText"
 *   app:radioTextImage="@drawable/radio_selector"/>
 * 
 * where radio_selector is a regular state drawable: 
 * 
 * <selector xmlns:android="http://schemas.android.com/apk/res/android">
 *    <item android:state_checked="true" android:drawable="@drawable/my_drawable_selected" />
 *    <item android:state_pressed="true" android:drawable="@drawable/my_drawable_selected" />
 *    <item android:drawable="@drawable/my_drawable" />
