删除顶栏在Android上xamarin形式

Question

我想包括一些解决方案：

<item name="android:actionBarSize">0dp</item> 

或

var activity = (Activity)Forms.Context; 
this.Window.AddFlags(WindowManagerFlags.Fullscreen); 

或

RequestWindowFeature(WindowFeatures.NoTitle); 

或活动串

Theme = "@style/MainTheme.FullScreen" 

但我找不到任何可行的解决方案，或者更确切地说，将歌词，电池时间等消除，但我仍然是顶级酒吧，我怎样才能完全删除它？

iOS上我已经添加：

UIApplication.SharedApplication.SetStatusBarHidden(true, true); 

和作品......但是Android，他是让我该死:) 解决方案？

我用xamarin形式PCL

我styles.xaml

<?xml version="1.0" encoding="utf-8" ?> 
<resources> 
    <style name="MainTheme" parent="MainTheme.Base"> 
    </style> 
    <!-- Base theme applied no matter what API --> 
    <style name="MainTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar"> 
    <!--If you are using revision 22.1 please use just windowNoTitle. Without android:--> 
    <item name="windowNoTitle">true</item> 
    <!--We will be using the toolbar so no need to show ActionBar--> 
    <item name="windowActionBar">false</item> 
    <!-- Set theme colors from http://www.google.com/design/spec/style/color.html#color-color-palette --> 
    <!-- colorPrimary is used for the default action bar background --> 
    <item name="colorPrimary">#2196F3</item> 
    <!-- colorPrimaryDark is used for the status bar --> 
    <!--<item name="colorPrimaryDark">#0084CA</item>--> 
    <!-- colorAccent is used as the default value for colorControlActivated 
     which is used to tint widgets --> 
    <item name="colorAccent">#2196F3</item> 
    <!-- You can also set colorControlNormal, colorControlActivated 
     colorControlHighlight and colorSwitchThumbNormal. --> 
    <item name="windowActionModeOverlay">true</item> 
    <!-- default --> 
    <item name="android:buttonStyle">@style/NoShadowButton</item> 

    <item name="android:datePickerDialogTheme">@style/AppCompatDialogStyle</item> 
    <item name="android:windowNoTitle">true</item> 
    <item name="android:windowFullscreen">true</item> 
    </style> 

    <style name="AppCompatDialogStyle" parent="Theme.AppCompat.Light.Dialog"> 
    <item name="colorAccent">#2196F3</item> 
    </style> 
    <style name="NoShadowButton" parent="android:style/Widget.Button"> 
    <item name="android:stateListAnimator">@null</item> 
    </style> 
</resources> 

Answer 1

public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity 
{ 
    protected override void OnCreate(Bundle bundle) 
    { 

    this.Window.AddFlags(WindowManagerFlags.Fullscreen | WindowManagerFlags.TurnScreenOn); 
     if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop) 
     { 
      var stBarHeight = typeof(FormsAppCompatActivity).GetField("statusBarHeight", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic); 
      if (stBarHeight == null) 
      { 
       stBarHeight = typeof(FormsAppCompatActivity).GetField("_statusBarHeight", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic); 
      } 
      stBarHeight?.SetValue(this, 0); 
     } 
     base.OnCreate(bundle); 


     global::Xamarin.Forms.Forms.Init(this, bundle); 

     LoadApplication(new App()); 
    } 
}

我的回答是Xamarin论坛这个类似的问题：

这两个项目添加到您的主题为你定活动：

<item name="android:windowNoTitle">true</item> 
<item name="android:windowFullscreen">true</item>

Answer 3

if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop) 
{ 
    Window.AddFlags(WindowManagerFlags.TranslucentStatus); 

    return; 
} 

仅凭这一点不会将状态栏下方视图，而是摆脱的状态栏下方的黑色空间（高度为20px左右）。
