javascript - Monodroid JavaScript 接口(interface)

Question

Monodroid 还不支持 WebView 的 JavaScriptInterface。

我正在寻找可用于此解决方法的示例 .java 文件。

IntPtr JavaScriptInterface_Class = JNIEnv.FindClass ("the/package/for/JavaScriptInterface");
IntPtr JavaScriptInterface_ctor = JNIEnv.GetMethodID (JavaScriptInterface_Class, "<init>", "()V");
IntPtr instance = JNIEnv.NewObject (JavaScriptInterface_Class, JavaScriptInterface_ctor);

appView.AddJavascriptInterface (new Java.Lang.Object (instance), "Android");

Answer 1

您可以使用自定义的 .java，例如:

// TODO: use an actually valid package name. :-)
package the.package.for;

public class JavaScriptInterface {
    // The JNI in the original question uses a default constructor.
    // Either provide one explicitly or use the implicit one...
    public JavaScriptInterface ()
    {
    }

    // TODO: add any methods you want invokable from JavaScript here.
}

不要忘记将 .java 文件的构建操作设置为 AndroidJavaSource。
