今天手机系统更新到android8.0 发现项目的WindowManager弹出框出错了，于是找了许久发现是android8.0的WindowManager属性type类型变更了
于是就做以8.0的SDK分界做了下判断就好了

 private WindowManager wm;
    private View windowFriendLocLayout;
    private WindowManager.LayoutParams lp;
    private boolean isShow = false;

    //弹出框 没有添加经纬度就提示添加经纬度
    private void showWindow() {
        if (wm == null) {
            wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
            lp = new WindowManager.LayoutParams();
            //窗口类型
            if (Build.VERSION.SDK_INT > 25) {
                lp.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
            } else {
                lp.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
            }
            lp.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
                    | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
            lp.gravity = Gravity.CENTER;
            // 设置图片格式，效果为背景透明
            lp.format = PixelFormat.RGBA_8888;
            lp.width = WindowManager.LayoutParams.MATCH_PARENT;
            lp.height = WindowManager.LayoutParams.MATCH_PARENT;
            windowFriendLocLayout = LayoutInflater.from(context).inflate(R.layout.window_getlat, null);
            //设置监听

            windowFriendLocLayout.findViewById(R.id.text_cancel).setOnClickListener(myOnClickListener);
            windowFriendLocLayout.findViewById(R.id.text_submit).setOnClickListener(myOnClickListener);
            TextView textView = (TextView) windowFriendLocLayout.findViewById(R.id.title);
            textView.setText("温馨提示");
            TextView textView1 = (TextView) windowFriendLocLayout.findViewById(R.id.content);
            textView1.setText("暂未通过认证，不可操作，去认证医生资质？");
        }
        if (!isShow) {
            wm.addView(windowFriendLocLayout, lp);
            isShow = true;
        }
    }

关键代码

  //窗口类型
            if (Build.VERSION.SDK_INT > 25) {
                lp.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
            } else {
                lp.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
            }
