推荐答案

任何Java本地code调用被调用，而无需使用任何插件如下。

Any Java Native code call be called without using any plugin as following.

按照以下步骤。

1. 更​​换以下code与您现有的DroidGap活动。

1. Replace the following code with your existing DroidGap Activity.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    super.init(); // Calling this is necessary to make this work
    appView.addJavascriptInterface(this, "MainActivity");

    /* "this" points the to the object of the current activity. "MainActivity" is used to refer "this" object in JavaScript as in Step 3. */

    super.loadUrl("file:///android_asset/www/index.html");
}

在当前（本）活动添加自定义函数如下。

Add the custom function in current (this) activity as following.

public void customFunctionCalled() {
    Log.e("Custom Function Called", "Custom Function Called");
}

现在从你的HTML / JavaScript的code调用这个函数如下。

Now call this function from your HTML/JavaScript code as following.

<script type="text/javascript">
    function callNewActivity() {
        window.MainActivity.customFunctionCalled();
    }
</script>

这将调用 customFunctionCalled（）在 MainActivity 。
