Question

我使用此脚本在doInbackground AsyncTask中获取注册ID，但注册ID仍为空。没有错误或强制关闭，但注册ID为空。

public class RegisterTask extends AsyncTask<String, Void, Integer> {

public RegisterTask(RegisterActivity activity, ProgressDialog progressDialog) {
    this.activity = activity;
    this.progressDialog = progressDialog;
}

@Override
protected void onPreExecute() {
    progressDialog.show();
}

@Override
protected Integer doInBackground(String... arg0) {
    inputFullName = (EditText) activity.findViewById(R.id.registerName);
    inputEmail = (EditText) activity.findViewById(R.id.registerEmail);
    inputPassword = (EditText) activity.findViewById(R.id.registerPassword);
    String name = inputFullName.getText().toString();
    String email = inputEmail.getText().toString();
    String password = inputPassword.getText().toString();
    Log.v(email, password);
    UserFunctions userFunction = new UserFunctions();

    // Make sure the device has the proper dependencies.
    GCMRegistrar.checkDevice(activity);

    // Make sure the manifest was properly set - comment out this line
    // while developing the app, then uncomment it when it's ready.
    GCMRegistrar.checkManifest(activity);

    // lblMessage = (TextView) findViewById(R.id.lblMessage);

    activity.registerReceiver(activity.mHandleMessageReceiver,
            new IntentFilter(DISPLAY_MESSAGE_ACTION));
    // Get GCM registration id
    regId = GCMRegistrar.getRegistrationId(activity);

    JSONObject json = userFunction.registerUser(name, email, password,
            regId);
    // check for login response
    try {
        if (json.getString(KEY_SUCCESS) != null) {
            // registerErrorMsg.setText("");
            String res = json.getString(KEY_SUCCESS);
            if (Integer.parseInt(res) == 1) {
                // user successfully registred
                // Store user details in SQLite Database
                DatabaseHandler db = new DatabaseHandler(
                        activity.getApplicationContext());
                JSONObject json_user = json.getJSONObject("user");

                // Clear all previous data in database
                userFunction.logoutUser(activity.getApplicationContext());
                db.addUser(json_user.getString(KEY_ID_USER),
                        json_user.getString(KEY_NAMA),
                        json_user.getString(KEY_EMAIL),
                        json_user.getString(KEY_REGID),
                        json_user.getString(KEY_JKEL),
                        json_user.getString(KEY_TLAHIR),
                        json_user.getString(KEY_INSTANSI),
                        json_user.getString(KEY_JABATAN),
                        json_user.getString(KEY_DIBUAT_AT),
                        json_user.getString(kEY_AVATAR),
                        json_user.getString(kEY_STATUS));
                // successful registration
                responseCode = 1;
            } else {
                // Error in registration
                responseCode = 0;
            }
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }

    return responseCode;
}

@Override
protected void onPostExecute(Integer responseCode) {
    EditText userName = (EditText) activity
            .findViewById(R.id.registerEmail);
    EditText passwordEdit = (EditText) activity
            .findViewById(R.id.registerPassword);
    String s = userName.getText().toString();

    if (responseCode == 1) {
        progressDialog.dismiss();
        activity.registerReport(responseCode);
        userName.setText("");
        passwordEdit.setText("");
    }
    if (responseCode == 0) {
        progressDialog.dismiss();
        activity.registerReport(responseCode);
    }
}
}

请帮助

您必须使用GCMRegistrar.register（mContext）发出获取id的请求。您必须在清单文件中声明接收器以启用接收注册和消息意图。现在要实际收到消息，您必须实现自己的服务，这将扩展GCMBaseIntentService。 Here您可以找到GCM的教程。

使用asynctask获取GCM注册ID
