            @Override
            public void onClick( View view ){
                Toast.makeText( MainActivity.this, "PUSH DOWN !!", Toast.LENGTH_SHORT ).show();
            }
        } )
        .setOnLongClickListener( new View.OnLongClickListener(){
            @Override
            public boolean onLongClick( View view ){
  Toast.makeText( MainActivity.this, "LONG PUSH DOWN !!", Toast.LENGTH_SHORT ).show();
                return true; // true: not effect to single click
            }
        } )
        .setOnTouchEvent( new View.OnTouchListener(){
            @Override
            public boolean onTouch( View view, MotionEvent motionEvent ){
                return false;
            }
        } );

Default values

Default mode: MODE_SCALE
Default scale: 0.97f
Default push duration: 50 millisecond
Default release duration: 125 millisecond
Default interpolator push/release: AccelerateDecelerateInterpolator()

「 MODE 」

1. MODE_SCALE: use range scale 0.00 - 1.00 to push down view.

EXAMPLE: This case 8dp ≈ 0.89 scale

PushDownAnim.setPushDownAnimTo( button )
 .setScale( MODE_SCALE, 0.89f  ) 
        ...;

2. MODE_STATIC_DP: use static dp unit to push down view.

EXAMPLE: 8dp static scale

PushDownAnim.setPushDownAnimTo( button )
 .setScale( MODE_STATIC_DP, 8  ) 
        ...;

「 Long Click 」

setOnClickListener(...)

@Override
public boolean onLongClick( View view ){
    ...
    return true; // true: not effect to single click
}

NOTE: If you do not want to trigger a normal click return true

「 Disable Click Programmatically 」

If your project has logic that want to disable click programmatically. You must use setEnabled(...) (do not use setClickable(...) it is not effective.)

button.setEnabled( false );
