在网络视图中使用暗模式

问题描述

我似乎无法获得android网络视图以使用深色主题或使用

I can't seem to be able to get android web view to use dark theme or use

@media (prefers-color-scheme: dark)

我正在使用具有DayNight主题的AndroidX

I am using AndroidX with DayNight theme

有人在api 29之前有向后兼容的解决方案吗?

Does anyone has a solution that is backward compatible before api 29?

推荐答案

添加到应用程序的build.grade:

Add to your app's build.grade:

implementation "androidx.webkit:webkit:1.2.0"

您可以在此处查看要使用的最新版本:

You can check the latest version to use here:

https://developer.android.com/jetpack/androidx/releases/webkit

如果您具有扩展WebView的类，则将其添加到扩展类的构造函数中:

If you have a class that extends WebView, then add this in your extending class' constructor:

  public MyWebView(Context context, AttributeSet attrs) {
       super(context, attrs);

       ...

      if (WebViewFeature.isFeatureSupported(WebViewFeature.FORCE_DARK)) {
          WebSettingsCompat.setForceDark(getSettings(), WebSettingsCompat.FORCE_DARK_ON);
      }

      ...
  }

如果您有一个实例化Web视图的活动，请将其添加到活动的onCreate方法:

If you have an activity that that instantiates a webview, add this to the activity's onCreate method:

    myWebView = getViewById(R.id.web_content);
    if (WebViewFeature.isFeatureSupported(WebViewFeature.FORCE_DARK)) {
        WebSettingsCompat.setForceDark(myWebView.getSettings(),
                                       WebSettingsCompat.FORCE_DARK_ON);
    }

当然，您可能需要决定要使用的力量策略:

Of course, you might want to decide which force strategy you want:

WebSettingsCompat.FORCE_DARK_ON
WebSettingsCompat.FORCE_DARK_OFF
WebSettingsCompat.FORCE_DARK_AUTO
