滑轮控件研究三、GestureDetector的中手势事件的测试

public class GestureTestActivity extends Activity {
private GestureDetector gestureDetector;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
gestureDetector=new GestureDetector(this, new GestureListener());
gestureDetector.setIsLongpressEnabled(false);
Log.i("test", ((new GestureListener()) instanceof OnDoubleTapListener)+"");
}

@Override
public boolean onTouchEvent(MotionEvent event) {
//经过测试，Android的多点触摸最多支持两点的触摸。
//将该Activity的touch事件交给GestureDetector处理
Log.i("count", event.getPointerCount()+"");
float x1=event.getX(0);
float y1=event.getY(0);
float x2=event.getX(1);
float y2=event.getY(1);
float x3=event.getX(2);
float y3=event.getY(2);
Log.i("test", "start the test!!!");
Log.i("test", x1+"");
Log.i("test", y1+"");
Log.i("test", "-------------------------------");
Log.i("test", x2+"");
Log.i("test", y2+"");
Log.i("test", "-------------------------------");
Log.i("test", x3+"");
Log.i("test", y3+"");
Log.i("test", "the next test!!!");
return gestureDetector.onTouchEvent(event);
}

//继承于SimpleOnGestureListener，实现所有事件监听方法
private class GestureListener extends SimpleOnGestureListener{
@Override
public boolean onDoubleTap(MotionEvent e) {
Log.i("test", "onDoubleTap");
return super.onDoubleTap(e);
}

@Override
public boolean onDoubleTapEvent(MotionEvent e) {
Log.i("test", "onDoubleTapEvent");
return super.onDoubleTapEvent(e);
}

@Override
public boolean onDown(MotionEvent e) {
Log.i("test", "onDown");
return super.onDown(e);
}

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
Log.i("test", "onFling");
return super.onFling(e1, e2, velocityX, velocityY);
}
@Override
public void onLongPress(MotionEvent e) {
Log.i("test", "onLongPress");
super.onLongPress(e);
}
@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
Log.i("test", "onScroll");
return super.onScroll(e1, e2, distanceX, distanceY);
}
@Override
public void onShowPress(MotionEvent e) {
Log.i("test", "onShowPress");
super.onShowPress(e);
}
@Override
public boolean onSingleTapConfirmed(MotionEvent e) {
Log.i("test", "onSingleTapConfirmed");
return super.onSingleTapConfirmed(e);
}
@Override
public boolean onSingleTapUp(MotionEvent e) {
Log.i("test", "onSingleTapUp");
return super.onSingleTapUp(e);
}

}
