class ZoomGesture extends GestureDetector.SimpleOnGestureListener {

-
@Override
-
public boolean onDoubleTap(MotionEvent e) {
-
System.out.println("--onDoubleTap---");
-
return true;
-

@Override
-
public boolean onScale(ScaleGestureDetector detector) {
-
detector.getCurrentSpan();
-
detector.getCurrentSpanX();
-

-

-
detector.getFocusY();
-

-
detector.getEventTime();

创建手势探测器
-
private GestureDetector gestureDetector;
-
private ScaleGestureDetector scaleGestureDetector;
-
...
-
gestureDetector = new GestureDetector(context, new ZoomGesture());
-
scaleGestureDetector = new ScaleGestureDetector(context, new ScaleGesture());
-
-
public boolean onTouchEvent(MotionEvent event) {
-
-
gestureDetector.onTouchEvent(event);
-
-
scaleGestureDetector.onTouchEvent(event);
-
return true;
-
}
