StrokeDescription的continueStroke这个方法根本就用不了啊，想用MyAccessibilityService模拟手势

[hellengoodd]

我用onTouch() 记录了所有手势点击的点, 然后用MyAccessibilityService里的dispatchGesture.模拟我记录的手势，但是StrokeDescription里的duration这个参数貌似会把这些点的距离根据时间平均掉. duaration时间越短，得到的手势路径就越不符合我记录的， 根本就不是我记录的那些点，中间好多点都被自动删除了，而且我记录的路径点跟点的时间都不一样，但是StrokeDescription里只能传入整个手势的总时间，不能插入路径中两个点之间的时间，后来我就发现了continueStroke 这个方法，发现这个方法根本就不工作，下面是我用来测试这个方法的代码，各位大佬麻烦帮看看，我google了下几乎没人用这个方法，我都怀疑android api的开发人员把这个方法遗忘了。。。

@RequiresApi(api = Build.VERSION_CODES.O)
    static public GestureDescription CreateGestureDescription(){
        Path dragRightPath = new Path();
        dragRightPath.moveTo(200, 200);
        dragRightPath.lineTo(400, 200);
        long dragRightDuration = 500L; // 0.5 second

        Path dragDownPath = new Path();
        dragDownPath.moveTo(400, 200);
        dragDownPath.lineTo(400, 400);
        long dragDownDuration = 500L;
        GestureDescription.StrokeDescription rightThenDownDrag =
                new GestureDescription.StrokeDescription(dragRightPath, 0L,
                        dragRightDuration, true);
        rightThenDownDrag.continueStroke(dragDownPath, dragRightDuration,
                dragDownDuration, false);
        GestureDescription.Builder clickBuilder = new GestureDescription.Builder();
        return clickBuilder.addStroke(rightThenDownDrag).build();
    }

而且，我发现我在slackoverflow问的好几个问题从来都没人回答过，不知道是啥原因。。。

谢谢各位大佬，老外不爱我希望国人爱我~~

这个貌似是无解的，谷歌应该限制了每秒只能发送多少个点，所以时间越短手势越不对。 还有那个continueStroke你用错了，如下

Path path = new Path();
path.moveTo(200, 200);
path.lineTo(400, 200);
final GestureDescription.StrokeDescription sd = new GestureDescription.StrokeDescription(path, 0, 500, true);
Path path2 = new Path();
path2.moveTo(400, 200);
path2.lineTo(400, 400);
final GestureDescription.StrokeDescription sd2 = sd.continueStroke(path2, 0, 500, false);
HongBaoService.mService.dispatchGesture(new GestureDescription.Builder().addStroke(sd).build(), new AccessibilityService.GestureResultCallback() {
    @Override
    public void onCompleted(GestureDescription gestureDescription) {
        super.onCompleted(gestureDescription);
        HongBaoService.mService.dispatchGesture(new GestureDescription.Builder().addStroke(sd2).build(), null, null);
    }

    @Override
    public void onCancelled(GestureDescription gestureDescription) {
        super.onCancelled(gestureDescription);
    }
}, null);

你说的是对的，太感谢了！！还以为没人理我了
