如何在android平台上使用js直接调用Java方法

Answer 1

例如，在下面的例子中我们会调用一个Java方法，它弹出一个android的Alert对话框。
//给我们熟悉的AppActivity类稍微加点东西
public class AppActivity extends Cocos2dxActivity {

private static AppActivity app = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
app = this;
}

public static void showAlertDialog(final String title,final String message) {

//这里一定要使用runOnUiThread
app.runOnUiThread(new Runnable() {
@Override
public void run() {
AlertDialog alertDialog = new AlertDialog.Builder(app).create();
alertDialog.setTitle(title);
alertDialog.setMessage(message);
alertDialog.setIcon(R.drawable.icon);
alertDialog.show();
}
});
}
}

然后我们在js中调用
jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "showAlertDialog", "(Ljava/lang/String;Ljava/lang/String;)V", "title", "hahahahha");
