Question

我正在使用android 4.4.2构建一个带有由辅助功能服务创建的系统覆盖/浮动窗口的应用程序。

编辑：我希望能够隐藏状态栏GLOBALLY（在任何应用中）（通过下面的代码实现）但是当显示叠加时我停止从收听者接收acessibilityEvents软件/硬件后退按钮当浮动视图注入windowmanager时：

AccessibilityEvent侦听器未收到更新
软件/硬件返回键未注册（主页/近期确实）

为了隐藏状态栏 ＆＃39; FLAG_FULLSCREEN |需要FLAG_NOT_TOUCH_MODAL＆＃39; 才能触及屏幕的其余部分并且 ＆＃39; View.SYSTEM_UI_FLAG_FULLSCREEN＆＃39; 允许

辅助功能服务（关于连接方法）：

  @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);

        }

辅助功能服务（关于连接方法）：

@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"
    />

Answer 1

经过长时间和一周的研究后，我发现由于安全限制，无法做到这两点。我将在我的应用程序的根模式下实现这些功能。

我正在使用的解决方法是一个简单的按钮，用于恢复系统ui并删除阻止可访问性输入的视图

嘿，我认为这会起作用!!!!

您只需要正确设置WindowManager.LayoutParams height width属性即可。通过这种方式，您可以从侦听器和软件/硬件后退按钮接收acessibilityEvents。

试试这个

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;
}
