Android MotionEvent中getX()和getRawX()的区别实例详解

实例代码：

publicclassResextendsActivityimplementsView.OnTouchListener { 
   
  Button btn =null; 
  intx =0; 
  inty =0; 
  intrawx =0; 
  intrawy =0; 
   
     
  @Override 
  publicvoidonCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    btn = (Button) findViewById(R.id.button); 
    btn.setOnTouchListener(this); 
  } 
   
  publicbooleanonTouch(View view, MotionEvent event) { 
    inteventaction = event.getAction(); 
    switch(eventaction) { 
    caseMotionEvent.ACTION_DOWN: 
      break; 
    caseMotionEvent.ACTION_MOVE: 
      x = (int) event.getX(); 
      y = (int) event.getY(); 
      rawx = (int) event.getRawX(); 
      rawy = (int) event.getRawY(); 
      Log.d("DEBUG","getX="+ x +"getY="+ y +"n"+"getRawX="+ rawx 
          +"getRawY="+ rawy +"n"); 
      break; 
   
    caseMotionEvent.ACTION_UP: 
   
      break; 
    } 
    returnfalse; 
  }
