隐藏状态栏辅助功能问题，Android浮动窗口 [英] Android floating window with hidden statusbar Accessibility problems

问题描述

我的工作是Android 4.4.2建设有无障碍服务创建的系统覆盖/浮动窗口的应用程序。

编辑：我希望能够在全球范围内隐藏状态栏（在任何应用程序）（由下面的code成为可能），然而，当显示叠加我停止接收来自acessibilityEvents监听器和软件/硬件后退按钮
当浮视图注入到窗口管理器：

1. AccessibilityEvent监听器没有收到更新


2. 软/硬件返回键不登记（家庭/ [近期所做的）

为了隐藏状态栏都 FLAG_FULLSCREEN | FLAG_NOT_TOUCH_MODAL的需要让触摸屏幕的其余部分和的View.SYSTEM_UI_FLAG_FULLSCREEN的可让

辅助服务（在连接方式）：

  @覆盖
    公共无效onServiceConnected（）{
        serviceInstance =这一点;
        窗口管理=（窗口管理器）getSystemService（WINDOW_SERVICE）;        FloatingView =新的视图（本）;        WindowManager.LayoutParams PARAMS =新WindowManager.LayoutParams（
                0，0，
                0，0，
                TYPE_PRIORITY_PHONE，
                FLAG_FULLSCREEN | FLAG_NOT_TOUCH_MODAL，PixelFormat.OPAQUE）;
        params.gravity = Gravity.CENTER_HORIZONTAL | Gravity.BOTTOM;
        params.windowAnimations = android.R.style.Animation_Toast;
        params.gravity = Gravity.BOTTOM | Gravity.RIGHT;            windowManager.addView（FloatingView，则params）; INT uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
  FloatingView.setSystemUiVisibility（uiOptions）;        }
 

辅助服务（在连接方式）：

  @覆盖
公共无效onAccessibilityEvent（AccessibilityEvent accessibilityEvent）{
    Log.i（，只需登录我一些垃圾）;}
 

我的AccessibilitySetup.xml：

 ＆LT;辅助服务的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
    机器人：accessibilityEventTypes =typeAllMask
    机器人：accessibilityFeedbackType =feedbackAllMask
    机器人：notificationTimeout =0
    机器人：accessibilityFlags =flagDefault
    机器人：canRetrieveWindowContent =真
    机器人：说明=@字符串/ notification_description
    /＆GT;
 

解决方案

长小时后和研究一个星期，我发现孤单没办法这两个做由于安全限制。我将在我的应用程序的根目录模式implmenet这些功能。

我现在用的解决方法是一个简单的按钮复兴的系统UI，并删除阻塞的辅助输入视图

I am working on android 4.4.2 building an application with a system overlay/floating window created by an accessibility service.

Edit:I want to be able to hide the status bar GLOBALLY (in any app) (made possible by the code below) however when the overlay is shown i stop receiving acessibilityEvents from the listener and the software/hardware back button When the floating view is injected into windowmanager:

1. AccessibilityEvent listener does not receive updates
2. Soft/hardware back key does not register (home/recents does)

in order to hide the status bar both 'FLAG_FULLSCREEN | FLAG_NOT_TOUCH_MODAL' are needed to allow touching the rest of the screen and 'View.SYSTEM_UI_FLAG_FULLSCREEN' allows

Accessibility Service (on connected method) :

  @Override
    public void onServiceConnected() {
        serviceInstance = this;
        windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

        FloatingView = new View(this);

        WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                0, 0,
                0, 0,
                TYPE_PRIORITY_PHONE,
                FLAG_FULLSCREEN | FLAG_NOT_TOUCH_MODAL, PixelFormat.OPAQUE);
        params.gravity = Gravity.CENTER_HORIZONTAL | Gravity.BOTTOM;
        params.windowAnimations = android.R.style.Animation_Toast;
        params.gravity = Gravity.BOTTOM | Gravity.RIGHT;

            windowManager.addView(FloatingView, params);

 int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
  FloatingView.setSystemUiVisibility(uiOptions);

        }

Accessibility Service (on connected method) :

@Override
public void onAccessibilityEvent(AccessibilityEvent accessibilityEvent) {
    Log.i("","Just log me some rubbish");

}

My AccessibilitySetup.xml:

<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeAllMask"
    android:accessibilityFeedbackType="feedbackAllMask"
    android:notificationTimeout="0"
    android:accessibilityFlags="flagDefault"
    android:canRetrieveWindowContent="true"
    android:description="@string/notification_description"
    />

解决方案

After long hours and a week of research i found theres is no way to do both of these due to security restrictions. i will implmenet these features in the root mode of my app.

the workaround i am using is a simple button that revives the system ui and removes the view that is blocking the accessibility input
