Android浮动窗口隐藏状态栏辅助功能问题

我正在开发 android 4.4.2 构建一个应用程序，该应用程序具有由辅助服务创建的系统覆盖/浮动窗口。

Edit:我希望能够全局隐藏状态栏（在任何应用程序中）（通过下面的代码实现）但是，当显示叠加层时，我停止从侦听器和软件/硬件后退按钮接收可访问性事件 当浮动视图注入windowmanager时：

1. AccessibilityEvent 侦听器未接收更新
2. 软/硬件后退键未注册（主页/最近的键已注册）

为了隐藏状态栏'FLAG_FULLSCREEN | FLAG_NOT_TOUCH_MODAL'需要允许触摸屏幕的其余部分并且'查看.SYSTEM_UI_FLAG_FULLSCREEN' allows

  @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);

        }

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

}

我的 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"
    />

嘿，我想这会起作用！

您只需要正确设置 WindowManager.LayoutParams height width 属性即可。 这样您就可以从侦听器和软件/硬件后退按钮接收可访问性事件。

Try this

WindowManager manager = ((WindowManager) context.getApplicationContext()
            .getSystemService(Context.WINDOW_SERVICE));
    WindowManager.LayoutParams localLayoutParams = new WindowManager.LayoutParams();
    localLayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
    localLayoutParams.gravity = Gravity.TOP;
    localLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
            // this is to enable the notification to receive touch events
            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
            // Draws over status bar
            WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
    localLayoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
    localLayoutParams.height = retrieveStatusBarHeight(context);
    localLayoutParams.format = PixelFormat.TRANSPARENT;
    StatusBarOverlayView view = new StatusBarOverlayView(context);
    manager.addView(view, localLayoutParams);

public static int retrieveStatusBarHeight(Context context) {
    int result = 0;
    int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0) {
        result = context.getResources().getDimensionPixelSize(resourceId);
    }
    return result;
}
