android - 如何通过 Facebook Android SDK 向好友发送应用请求

Question

目前我正在使用 Facebook SDK 开发一个 Android 应用程序。它可以很好地向墙上发布消息等，但是通过这个 SDK 我无法向其他人发送应用程序请求。

谁能帮帮我？

这是我的代码 fragment :

Bundle params = new Bundle();
params.putString("message", getString(R.string.request_message));
Utility.mFacebook.dialog(Hackbook.this, "apprequests", params, new AppRequestsListener());

和AppRequestsListener:

public class AppRequestsListener extends BaseDialogListener {
    @Override
    public void onComplete(Bundle values) {
        Toast toast = Toast.makeText(getApplicationContext(), "App request sent", Toast.LENGTH_SHORT);
        toast.show();
    }

    @Override
    public void onFacebookError(FacebookError error) {
        Toast.makeText(getApplicationContext(), "Facebook Error: " + error.getMessage(), Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onCancel() {
        Toast toast = Toast.makeText(getApplicationContext(), "App request cancelled", Toast.LENGTH_SHORT);
        toast.show();
    }
}

从 SDK 3.0 版开始，您可以使用 WebDialog。下面是一个示例，说明如何使用提供的构建器创建一个使用所有可用参数的构建器:

private void sendRequestDialog() {
    Bundle params = new Bundle();
    params.putString("title", "Send a Request");
    params.putString("message", "Learn how to make your Android apps social");
    params.putString("to", "12343543,32423534");  // comma seperated list of facebook IDs to preset the recipients. If left out, it will show a Friend Picker.
    params.putString("data",
        "{\"badge_of_awesomeness\":\"1\"," +
        "\"social_karma\":\"5\"}");  // any additional data

    WebDialog requestsDialog = (
        new WebDialog.RequestsDialogBuilder(getActivity(), Session.getActiveSession(), params))
            .setOnCompleteListener(new OnCompleteListener() {

                @Override
                public void onComplete(Bundle values, FacebookException error) {
                    // do something, e.g. show toast message
                }   
            })
            .build();
    requestsDialog.show();
}
