安卓：显示/隐藏状态栏/力量吧 [英] Android: show/hide status bar/power bar

问题描述

我想创建一个按钮，在那里我可以隐藏或显示在我的平板电脑的状态栏。

I am trying to create a button where I can hide or show the status bar on my tablet.

我已经把在OnCreate

I've put in the onCreate

getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

和在按钮 显示：

WindowManager.LayoutParams attrs = getWindow().getAttributes();
attrs.flags &= ~WindowManager.LayoutParams.FLAG_FULLSCREEN;
getWindow().setAttributes(attrs);

隐藏：

WindowManager.LayoutParams attrs = getWindow().getAttributes();
attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
getWindow().setAttributes(attrs);

任何提示/的窍门？

Any hints/tipps?

//修改

我已经看了这个提示在这里： http://android.serverbox.ch/?p=306 并改变了我的code是这样的：

I've looked at this hint here: http://android.serverbox.ch/?p=306 and changed my code like this:

private void hideStatusBar() throws IOException, InterruptedException {
    Process proc = Runtime.getRuntime().exec(new String[]{"su","-c","service call activity 79 s16 com.android.systemui"});
    proc.waitFor();
}

private void showStatusBar() throws IOException, InterruptedException {
    Process proc = Runtime.getRuntime().exec(new String[]{"am","startservice","-n","com.android.systemui/.SystemUIService"});
    proc.waitFor();
}

所以，如果我点击我的按钮的调用方法我可以看到某些事情正在发生，因为应用程序在等待几秒钟。 我也看了成LockCat，看到某些事情正在发生。

So if I click on my buttons an the methods are called I can see that something is happening because the app is waiting some seconds. I also looked into LockCat and see that something is happening.

推荐答案

你有全屏主题在清单中设置？

Do you have the fullscreen theme set in the manifest?

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

我不认为你可以去全屏没有这个。

I don't think you'll be able to go fullscreen without this.

我会用下面的添加和删除全屏标志：

I would use the following to add and remove the fullscreen flag:

// Hide status bar
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
// Show status bar
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
