[android] 롤리팝 : 투명하게 설정된 색상으로 statusBar 뒤에 그리기

Cody Toombs의 솔루션은 거의 나를 위해 속임수를 사용했습니다. 이것이 Xamarin 과 관련 이 있는지 확실 하지 않지만 이제 수용 가능한 해결책이 있습니다.

이것은 내 설정입니다.

Android.Support v4 및 v7 패키지를 참조한 Android 프로젝트가 있습니다. 두 가지 스타일이 정의되어 있습니다.

values ​​/ styles.xml :

<?xml version="1.0" encoding="UTF-8" ?>
<resources>
    <style name="MyStyle" parent="@style/Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowTranslucentStatus">true</item>
    </style>
</resources>

values-v21 / styles.xml :

<?xml version="1.0" encoding="UTF-8" ?>
<resources>
    <style name="MyStyle" parent="@style/Theme.AppCompat.Light.NoActionBar">
        <item name="android:statusBarColor">@android:color/transparent</item>
    </style>
</resources>

AndroidManifest는 “MyStyle”을 대상으로합니다.

AndroidManifest.xml :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="com.agn.test.test">
    <uses-sdk android:minSdkVersion="10" />
    <application android:allowBackup="true" android:icon="@mipmap/icon" android:label="@string/app_name" android:theme="@style/MyStyle">
    </application>
</manifest>

그리고 마지막으로 주요 활동의 코드 :

[Activity (Label = "Test", MainLauncher = true, Icon = "@mipmap/icon")]
public class MainActivity : Activity
{
    protected override void OnCreate (Bundle savedInstanceState)
    {
        base.OnCreate (savedInstanceState);

        SetContentView (Resource.Layout.Main);
        //Resource.Layout.Main is just a regular layout, no additional flags. Make sure there is something in there like an imageView, so that you can see the overlay.

        var uiOptions = (int)Window.DecorView.SystemUiVisibility;
        uiOptions ^= (int)SystemUiFlags.LayoutStable;
        uiOptions ^= (int)SystemUiFlags.LayoutFullscreen;
        Window.DecorView.SystemUiVisibility = (StatusBarVisibility)uiOptions;

        Window.AddFlags (WindowManagerFlags.DrawsSystemBarBackgrounds);
    }
}

DrawsSystemBarBackgrounds 플래그를 설정하면 모든 차이가 발생합니다.

Window.AddFlags (WindowManagerFlags.DrawsSystemBarBackgrounds); 

사실 너무 많은 시간을 제대로 보냈습니다. 이 답변이 같은 일을 달성하려는 사람에게 도움이 되길 바랍니다.
