Question

SYSTEM_ALERT_WINDOW

有几个问题

设备进入休眠状态（屏幕锁定或屏幕关闭）后，看不到我的系统警报窗口
有时无法点击按钮closeWindow（）但不明白为什么。也许有人可以解释一下？
Android 6不再显示此窗口？来自Android设备的任何反应。

我的代码示例

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        mContext = this.getApplicationContext();
        String phone = intent.getStringExtra("phone").replace("+", "");
        Log.d(LOG_TAG, "WindowService::showWindow()");

    try {
        Map<String, String> map = new HashMap<>();

        FCINetwork fciNetwork = new FCINetwork(mContext);
        if (fciNetwork.isNetworkAvailable()) {
            ArrayList<String> obj = new RequestTask(mContext).execute(phone).get();

            if (obj.get(0).indexOf("0") != -1) {
                map.put("phone_number", phone);
                map.put("personal_data", mContext.getString(R.string.unknown_caller));
                map.put("company", "");
                map.put("position", "");
            } else {
                map.put("phone_number", phone);
                map.put("personal_data", obj.get(1) + " " + obj.get(2));
                map.put("company", obj.get(3));
                map.put("position", "");
                showWindow(mContext, map);
            }
        }
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (ExecutionException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }

    return super.onStartCommand(intent, flags, startId);
}

@Override
public void onCreate() {
    super.onCreate();
    Log.d(LOG_TAG, "Service start");
}


@Override
public void onDestroy() {
    super.onDestroy();

    Log.d(LOG_TAG, "Service stop");
    Log.d(LOG_TAG, "WindowsService::closeWindow()");
    closeWindow();
}

private void showWindow(Context context, Map<String, String> data) {
    windowManager = (WindowManager) context.getSystemService(context.WINDOW_SERVICE);
    LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);

    WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.MATCH_PARENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
            PixelFormat.TRANSLUCENT
    );

    params.gravity = Gravity.TOP;

    viewGroup = (ViewGroup) layoutInflater.inflate(R.layout.info, null);

    TextView phoneNumber = (TextView) viewGroup.findViewById(R.id.phone_number);
    phoneNumber.setText(data.get("phone_number"));
    TextView personalData = (TextView) viewGroup.findViewById(R.id.personal_data);
    personalData.setText(data.get("personal_data"));
    TextView company = (TextView) viewGroup.findViewById(R.id.company);
    company.setText(data.get("company"));
    TextView position = (TextView) viewGroup.findViewById(R.id.position);
    position.setText(data.get("position"));

    Button buttonClose = (Button) viewGroup.findViewById(R.id.button_close);
    buttonClose.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            closeWindow();

        }
    });
    windowManager.addView(viewGroup, params);
    Log.d("SERVICE", "WORKING");
}

private void closeWindow() {
    if (viewGroup != null && windowManager != null) {
        windowManager.removeView(viewGroup);
        viewGroup = null;
    }
}

感谢您的帮助

我认为会解决1个屏幕锁定问题

WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.MATCH_PARENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
               WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
                WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                        | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
                        | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
                ,
                PixelFormat.TRANSLUCENT
        );

在默认来电者屏幕前显示系统弹出窗口
