滑轮控件研究三、GestureDetector的中手势事件的测试

直接代码，很简单

[java] view
plaincopy

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);

}

}

}
