and to dim the bar i used

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

Answer 1

Use the following in your Manifest

<activity
        android:name=".abc"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >

This however will only work on phones, Tablets do not support hiding of status bar.

Answer 2

在onCreate方法上尝试使用它。

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

Answer 3

1. add a style and extend Theme.AppCompat.NoActionBar , and add two item.

like this

 <style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowContentOverlay">@null</item>
    </style

2. setup your application with this theme.

like this

<application
    ...
    android:theme="@style/AppTheme"
    ...>
</application>

Answer 4

In your AndroidManifest just add it to android:theme . Either of the following lines should work for you:

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

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

You need to specify Fullscreen otherwise your status bar will be kept and only your Title bar will disappear.

Answer 5

View.SYSTEM_UI_FLAG_HIDE_NAVIGATION doesn't hide the status bar. It hides the navigation bar. If you want to hide the status bar you should use:

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

or

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
