AndroidManifest.xml
<activity ...
android:theme="@style/FullScreenTheme"

</activity>
I.你的主应用的主题是theme . appcompat . light . darkactionbar
隐藏ActionBar / StatusBar style.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
...
</style>
<style name="FullScreenTheme" parent="AppTheme">
<!--this property will help hide the ActionBar-->
<item name="windowNoTitle">true</item>
<!--currently, I don't know why we need this property since use windowNoTitle only already help hide actionbar. I use it because it is used inside Theme.AppCompat.Light.NoActionBar (you can check Theme.AppCompat.Light.NoActionBar code). I think there are some missing case that I don't know-->
<item name="windowActionBar">false</item>
<!--this property is used for hiding StatusBar-->
<item name="android:windowFullscreen">true</item>
</style>
隐藏系统导航栏
public class MainActivity extends AppCompatActivity {
protected void onCreate(Bundle savedInstanceState) {
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
setContentView(R.layout.activity_main)
...
}
}

奇巧有一种叫做沉浸式全屏模式的技术。
例子
小心
requestWindowFeature(Window.FEATURE_NO_TITLE);
如果您正在使用任何方法设置操作栏如下:
getSupportActionBar().setHomeButtonEnabled(true);
它将导致一个空指针异常。
https://developer.android.com/training/system-ui/immersive.html
活动:
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus) {
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
}
安卓清单:
<activity android:name=".LoginActivity"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="@string/title_activity_login"
android:theme="@style/FullscreenTheme"
></activity>
AndroidManifest.xml
<activity ...
android:theme="@style/FullScreenTheme"
>
</activity>
