Honeycomb - AlertDialog 期间隐藏状态栏

发布于 2025-01-02 18:52:03 字数 375 浏览 2 评论 0原文

我在显示 AlertDialog 时遇到了 Honeycomb (3.2) 中状态栏可见性的问题。在我的 HomeActivity 中，我通过以下代码将状态栏可见性设置为隐藏：

View v = findViewById(R.id.toplevelview);
v.setSystemUiVisibility(View.STATUS_BAR_HIDDEN);

到目前为止，这效果很好，并且应该在我的整个应用程序中保持如此。但是，当我通过 AlertDialogBuilder 创建新的 AlertDialog 并显示它时，状态栏可见性不再隐藏。我是否必须再次明确设置状态栏可见性或其他什么？我尝试了一些东西，但没有任何主题可以工作。

谢谢你帮助我！

I have a problem with the status bar visibility in Honeycomb (3.2) while showing an AlertDialog. In my HomeActivity I set the status bar visibility to hidden by the following code:

View v = findViewById(R.id.toplevelview);
v.setSystemUiVisibility(View.STATUS_BAR_HIDDEN);

So far this works great and should stay so in my whole application. But when I create a new AlertDialog via the AlertDialogBuilder and show it the status bar visibility isn't hidden any more. Do I have to set the status bar visibility explicitly again or something? I have tried a few things, but nothing themes to work.

Thanks for helping me!

是的，我认为每个活动和对话框都需要设置它。

这可以工作，有点：

protected void onPrepareDialog (int id, Dialog dialog) {
    View main_layout = dialog.findViewById(android.R.id.content).getRootView();
    main_layout.setSystemUiVisibility(View.STATUS_BAR_HIDDEN);
}

问题是，至少在我正在开发的 Honeycomb ROM 中（Flashback 10.3），当对话框显示时，你仍然会看到状态栏的短暂闪烁，或者看起来是这样。我是菜鸟，所以我可能会做错对话。

实际上，我知道我做的对话框是错误的，因为“onPrepareDialog”已被弃用（链接）。接下来我将弄清楚片段和片段管理器。

我仍然无法隐藏状态栏的唯一一次是弹出微调器的选项时。看来这应该是应用程序级别的设置......

Yep, I think each activity and dialog needs to set it.

This works, sort of:

protected void onPrepareDialog (int id, Dialog dialog) {
    View main_layout = dialog.findViewById(android.R.id.content).getRootView();
    main_layout.setSystemUiVisibility(View.STATUS_BAR_HIDDEN);
}

The problem is, at least in the Honeycomb ROM I'm developing with (Flashback 10.3), you still get a brief flash of the status bar as the dialog is shown, or so it seems. I'm a noob, so I might be doing dialogs wrong.

Actually, I KNOW I'm doing dialogs wrong because "onPrepareDialog" is deprecated (linky). I'll be figuring out fragments and the fragment manager next.

The only other time I still can't hide the status bar is when the choices pop-up for a spinner. Seems like this should be an app level setting...
