我正在使用 JAVA Android SDK 开发 Deezer 应用程序。我已经设法使用 Deezer 方法登录（出现一个允许用户使用他的 deezer 或 facebook 帐户登录的弹出窗口）。

但现在我想访问用户数据（姓名/身份证...）以备将来使用。我目前正在使用

DeezerRequest request_name = new DeezerRequest("/user/me");

但是应用程序抛出异常，要求获取 access_token。我有它，但我不知道如何将它提供给请求（并且 deezer 开发网站并没有真正的帮助，因为他认为你知道如何处理它）

如果有帮助，我可以发布更多代码。谢谢你的帮助。

正确登录后，这是我使用的代码（取自您的 sdk zip 文件中的示例 Deezer 应用程序）

在您的活动中：

private RequestListener userRequestListenerHandler = new UserRequestHandler();

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

....

searchUser();
}

public void searchUser(){

    AsyncDeezerTask searchAsyncUser = new AsyncDeezerTaskWithDialog(this,  deezerConnect, userRequestListenerHandler);
        DeezerRequest request = new DeezerRequest("user/me");
        searchAsyncUser.execute(request);

}

public void searchUserFinish(User user) {
        // TODO Auto-generated method stub
        String name = user.getFirstname();
        Sring lastname = user.getLastname();
        //... other user data
        }


private class UserRequestHandler implements RequestListener{

        @Override
        public void onComplete(String response, Object arg1) {
            // TODO Auto-generated method stub

            try{


                User user = new DeezerDataReader<User>(User.class).read(response);

                searchUserFinish(user);

            }catch (IllegalStateException e){
                handleError(e);
                e.printStackTrace();
            }

        }

        @Override
        public void onDeezerError(DeezerError e, Object arg1) {
            // TODO Auto-generated method stub
            handleError(e);
        }

        @Override
        public void onIOException(IOException e, Object arg1) {
            // TODO Auto-generated method stub
            handleError(e);
        }

        @Override
        public void onMalformedURLException(MalformedURLException e,
                Object arg1) {
            // TODO Auto-generated method stub
            handleError(e);

        }

        @Override
        public void onOAuthException(OAuthException e, Object arg1) {
            // TODO Auto-generated method stub
            handleError(e);
        }

    }

public void handleError(Error e){
Toast.maketext(this,e,Toast.Length_Short).show();
}

ASYNC DEEZER 任务

public class AsyncDeezerTaskWithDialog extends AsyncDeezerTask {
    /** Progress dialog to show user that the request is beeing processed. */
    private ProgressDialog progressDialog;

    /**
     * Simply creates an Deezer task with a dialog.

    public AsyncDeezerTaskWithDialog(Context context, DeezerConnect deezerConnect,
            RequestListener listener ) {
        super(deezerConnect, listener );
        progressDialog = new ProgressDialog( context );
        progressDialog.setCancelable( true );
        progressDialog.setOnCancelListener( new OnCancelHandler() );

DEEZER 数据阅读器类

public class DeezerDataReader<T extends Object> {

    /** Class to pass to the Gson parser to create POJOs. */
    private Class<T> clazz = null;

    /** Creates a reader.

太好了，有人帮我将访问令牌链接到 deezerConnect ：

/** DeezerConnect object used for auhtentification or request. */
private DeezerConnect deezerConnect = new DeezerConnectImpl(APP_ID);
//----
deezerConnect.setAccessToken(getApplicationContext(), access_token);

获得访问令牌的原因是

deezerConnect.authorize(MainActivity.this, PERMISSIONS,
            new LoginDialogHandler());

//----
private class LoginDialogHandler implements DialogListener {
    @Override
    public void onComplete(final Bundle values) {

        MainActivity.access_token = values.getString("access_token");
    }
//----
}
