直播平臺搭建Android 6.0禁止狀態欄下拉

描述：只需要在PhoneStatusBarView的onTouchEvent攔截事件傳遞即可
 
 
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        boolean barConsumedEvent = mBar.interceptTouchEvent(event);
 
        if (DEBUG_GESTURES) {
            if (event.getActionMasked() != MotionEvent.ACTION_MOVE) {
                EventLog.writeEvent(EventLogTags.SYSUI_PANELBAR_TOUCH,
                        event.getActionMasked(), (int) event.getX(), (int) event.getY(),
                        barConsumedEvent ? 1 : 0);
            }
        }
 
//        return barConsumedEvent || super.onTouchEvent(event);
        return false;
    }
