Spen触摸监听器不工作后更新到棒棒糖

Question

我使用SPenEventLibrary来识别触摸是通过手指还是Spen完成的。在我升级到Android l之前，它一直在工作。

设备:Galaxy Note 3。

spenlib是最新的:libspen23.jar, pen-v3.1.8.jar

Android版本:5.0

代码很简单:

mSPenEventLibrary.setSPenTouchListener(this, new SPenTouchListener(){
        @Override
        public boolean onTouchFinger(View view, MotionEvent event) {
            if (ApplicationPreferences.get(mContext).getSPENWristGaurdOnOff() == false) {
                return handleEvent(event);
            } else {
                return true;
            }
        }
        @Override
        public boolean onTouchPen(View view, MotionEvent event) {
            return handleEvent(event);
        }
        @Override
        public void onTouchButtonDown(View arg0, MotionEvent arg1) {
        }
        @Override
        public void onTouchButtonUp(View arg0, MotionEvent arg1) {
        }
        @Override
        public boolean onTouchPenEraser(View arg0, MotionEvent arg1) {
        }
    });

当我用Spen触摸屏幕时，调用onTouchFinger()而不是onTouchPen()。在旧的Android版本中onTouchPen()被调用

这是来自三星开发者论坛的回答:

公共布尔onTouch(视图视图，MotionEvent事件){

boolean done = false;
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
    if (event.getMetaState() == 0) {
        //Finger
        // Do whatever you need to do here
        done = true;
    }
    else if(event.getMetaState() == 512) {
        //Pen
        // Do whatever you need to do here
        done = true;
    }
}
else {
    if (event.getToolType(0) == MotionEvent.TOOL_TYPE_FINGER) {
        //Finger
        // Do whatever you need to do here
        done = true;
    }
    else if(event.getToolType(0) == MotionEvent.TOOL_TYPE_STYLUS) {
        //Pen
        // Do whatever you need to do here and then
        done = true;
    }
}
if (done)
    return true;
return super.onTouch(view, event);

}
