Ripple Efftect for Custom View

If you want to add ripple effect for your custom view.

1. Create a RippleManager object in your custom view.

   RippleManager mRippleManager = new RippleManager();

2. Call onCreate() method of RippleManager in view's constructor.

   mRippleManager.onCreate(this, context, attrs, defStyleAttr, defStyleRes);

3. Override setOnClickEvent() and onTouchEvent().

   @Override
   public void setOnClickListener(OnClickListener l) {
       if(l == mRippleManager)
           super.setOnClickListener(l);
        else{
           mRippleManager.setOnClickListener(l);
           setOnClickListener(mRippleManager);
       }	
   }
   
   @Override
   public boolean onTouchEvent(@NonNull MotionEvent event) {
       boolean result = super.onTouchEvent(event);

##State XML To define states for LineMorphingDrawable, you need to create a XML file with format:

<state-list>
    
    <state>			    <!-- the first state !-->
        <points>                    <!-- all value are fraction !-->
        	<item>0.5</item>    <!-- the x value of start point of first line segment !-->
        	<item>0</item>      <!-- the y value of start point of first line segment !-->
        	<item>0.5</item>    <!-- the x value of end point of first line segment !-->
        	<item>1</item>      <!-- the y value of end point of first line segment !-->
        	
        	<item>0</item>      <!-- the x value of start point of second line segment !-->
        	<item>0.5</item>    <!-- the y value of start point of second line segment !-->
        	<item>1</item>      <!-- the x value of end point of second line segment !-->
        	<item>0.5</item>    <!-- the y value of end point of second line segment !-->
            ...
        </points>     

        <links>               <!-- Each pair of values define the index of 2 line segment that are linked !-->
        	<item>0</item> 	
        	<item>1</item>
        </links>    
  
    </state>
