Android平板电脑导航栏不会隐藏

I'm trying to hide the navigation bar, using methods I've found described on the internet.

我试图隐藏导航栏，使用我在互联网上找到的方法。

I have a simple layout which shows a WebView:

我有一个简单的布局，显示WebView：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal"
    android:id="@+id/layout" >

    <WebView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/webview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

</RelativeLayout>

The code that I'm using at app startup is:

我在app启动时使用的代码是：

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
    web.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
    layout.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

But this doesn't hide the navigation bar.

但这并不隐藏导航栏。

I've added...

我已经添加...

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

... to my activity too.

......也参加我的活动。

How can I achieve this?

我怎样才能做到这一点？

3 个解决方案

#1

You cannot permanently hide the system bar on a tablet.

您无法永久隐藏平板电脑上的系统栏。

SYSTEM_UI_FLAG_HIDE_NAVIGATION on Android 4.1 and higher will hide the system bar, but it will reappear as soon as the user does anything.

Android 4.1及更高版本上的SYSTEM_UI_FLAG_HIDE_NAVIGATION将隐藏系统栏，但只要用户执行任何操作，它就会重新出现。

#2

you can hide the navigationbar,try this

你可以隐藏导航栏，试试这个

public void FullScreencall() {
    if(Build.VERSION.SDK_INT < 19) //19 or above api
        View v = this.getWindow().getDecorView();
        v.setSystemUiVisibility(View.GONE);
    } else {
            //for lower api versions.
        View decorView = getWindow().getDecorView(); 
        int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
        decorView.setSystemUiVisibility(uiOptions);
    }
}

#3

You can not hide the navigation bar within the given framework. However, there is a work around if rooting the device is an option for you:

您无法隐藏给定框架内的导航栏。但是，如果根设备是您的选项，则可以解决此问题：

Root device

根设备
Install and run Busybox

安装并运行Busybox
Install HideBar

安装HideBar

In HideBar there is an option to run in 'Kiosk' mode, in which there is no way to re-display the navigation bar. Needless to say, you really need to be careful with this.

在HideBar中，有一个选项可以在“Kiosk”模式下运行，在该模式下无法重新显示导航栏。不用说，你真的需要小心这一点。
