在Codename中访问和使用一个原生Android类 [英] Access and use in Codename One native Android classes

问题描述

我知道Codename One和Android是完全不同的框架。但是问题是，如何从本地Android中访问Codename One类？

I know that Codename One and Android are completely different frameworks. But the question is, How can I access in Codename One classes from native Android?

例如：我想创建一个名为 onCreat（）的方法看起来像这样：

eg: I want to create a method called onCreat() that looks like this:

public void onCreate(Bundle savedInstanceState){}

在Android中，您必须导入软件包 import android.os.Bundle;

In Android you have to import the package import android.os.Bundle;

如何集成此程序包（用于 onCreat（））和其他Android程序包中的代号One ？

How can I integrate this package (for onCreat()) and other packages from Android in codenamed One?

我应该在Code Name One中设置什么才能访问这些类。

What should I set in Code Name One that I can access these classes. Is this possible?

编辑：

另一个示例：

  import android.net.Uri;
  public void startWeb(View v) {
       Uri uri = Uri.parse("http://www.google.com");
       Intent intent = new Intent(Intent.ACTION_VIEW, uri);
       startActivity(intent);    
    }

我该如何在Codename One中转换此Android代码，使其看起来像这样并且，如果我单击按钮，则可以正常工作：

How can i convert this Android code in Codename One so that it looks like this and, if i click on the Button, works:

 protected void onMain_Button6Action(Component c, ActionEvent event) {
       Uri uri = Uri.parse("http://www.google.com");
       Intent intent = new Intent(Intent.ACTION_VIEW, uri);
       startActivity(intent);    
    }

重点是我想了解如何制作代号的Android代码一种功能。

The point is that I want to understand how I make the Android code for Codename One functional.

谢谢。

推荐答案

您需要使用< a href = http://www.codenameone.com/how-do-i---access-native-device-functionality-invoke-native-interfaces.html rel = nofollow>原生接口访问android原生功能。但是，onCreate调用是一种特殊情况，因为它是Android应用程序生命周期中的回调，将被调用以启动Codename One的start / init方法，并且不会调用您的代码。

You need to use native interfaces to access the android native functionality. However, the onCreate call is a special case since its a callback from the lifecycle of the Android application and will be invoked to launch the Codename One start/init methods and will not invoke your code.

要收听这些生命周期调用，可以使用AndroidNativeUtil类，该类具有一个生命周期侦听器，可让您从本机接口访问这些功能。

To listen to those lifecycle calls you can use the AndroidNativeUtil class which has a lifecycle listener that allows you to access those features from the native interfaces.
