如何显示全屏窗口TYPE_SYSTEM_ALERT？ [英] How to display a fullscreen TYPE_SYSTEM_ALERT window?

问题描述

我目前有一个困难时期显示在全屏模式下的TYPE_SYSTEM_ALERT窗口。我想，才能有重叠角度，从服务创建这样做，在状态栏的顶部，但没有隐藏它。

I'm currently having a hard time displaying a TYPE_SYSTEM_ALERT window in fullscreen mode. I'd like to do so in order to have an overlay view, created from a service, on top of the status bar but without hiding it.

不过，把FLAG_FULLSCREEN国旗在我创建了窗口的布局PARAMS似乎并没有工作。我发现STATUS_BAR和EXPAND_STATUS_BAR权限，但我找不到如何使用它们。

However, putting the FLAG_FULLSCREEN flag in the layout params of the window I'm creating doesn't seem to work. I found the STATUS_BAR and EXPAND_STATUS_BAR permissions but I couldn't find how to make use of them.

下面是的LayoutParams：

Here are the LayoutParams :

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

    params.gravity = Gravity.RIGHT | Gravity.TOP;

    mWindowManager.addView(mOverlayView, params);

任何想法？

感谢您

推荐答案

我找到了解决办法，同时试图做别的事情！

I found the solution while trying to do something else!

为了让每一个其他窗口的顶部，并在状态栏必须添加FLAG_LAYOUT_IN_SCREEN标志，而不是FLAG_LAYOUT_FULLSCREEN标志的顶部TYPE_SYSTEM_ALERT窗口：

In order to have a TYPE_SYSTEM_ALERT window on top of every other window AND on top of the status bar you must add the FLAG_LAYOUT_IN_SCREEN flag and not the FLAG_LAYOUT_FULLSCREEN flag :

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

mWindowManager.addView(mOverlayView, params);
