Android MotionEvent中getX()和getRawX()的区别

RawX,RawY 相对于屏幕位置坐标
X,Y 相对于容器的位置坐标

测试代码:

public class Res extends Activity implements View.OnTouchListener {
Button btn = null;
int x = 0;
int y = 0;
int rawx = 0;
int rawy = 0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btn = (Button) findViewById(R.id.button);
btn.setOnTouchListener(this);
}
public boolean onTouch(View view, MotionEvent event) {
int eventaction = event.getAction();
switch (eventaction) {
case MotionEvent.ACTION_DOWN:
break;
case MotionEvent.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;
case MotionEvent.ACTION_UP:
break;
}
return false;
}
}

总结:

getX()是表示Widget相对于自身左上角的x坐标

而getRawX()是表示相对于屏幕左上角的x坐标值(注意:这个屏幕左上角是手机屏幕左上角,不管activity是否有titleBar或是否全屏幕),getY(),getRawY()一样的道理
