我在看ScaleGestureDetector類。 http://developer.android.com/reference/android/view/ScaleGestureDetector.htmlAndroid Touchevent - 捏手勢
我有兩種方法，Zoom-In and ZoomOut。我應該採用哪種方法來調用這兩種方法。
private class ScaleListener extends ScaleGestureDetector.SimpleOnScaleGestureListener {@
Override
public boolean onScale(ScaleGestureDetector detector) {
return true;
}
Override
public boolean onScaleBegin(ScaleGestureDetector detector) {
return true;
}
Override
public boolean onScaleEnd(ScaleGestureDetector detector) {
}
}
讓我做一個捏起來的走，我想打電話給Zoom-In和捏下來，我想打電話給Zoom-out。
