android - Android如何隐藏默认主页，时间显示栏在android中

Question

嗨，任何人都知道如何隐藏默认主页，返回时间显示系统栏由 android？

Answer 1

I suggest you want to make it fullscreen, therefore you can use this:

You can hide the default system bar by using the following code for an activity in the AndroidManifest.xml file:

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

Here an example of a splash screen:

<activity
        android:name=".SplashScreen"
        android:label="@string/app_name"
        android:noHistory="true"
        android:screenOrientation="landscape"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

You should put it in every activity that must be fullscreen. Using this line of code in the <application> tag is not going to work.

Answer 2

在 Android 4.0 及更高版本上，您可以使用SYSTEM_UI_FLAG_HIDE_NAVIGATION

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

但是，您似乎在谈论 Android 3.0，因为它通常会在导航旁边显示电池电量等。无法使用 Android SDK 隐藏此栏，但有一些替代方法，如本问题所述。
