使用Robotium .getString（）方法从R.string返回错误

Question

I try to get Android settings from R.string using Robotium

String loginButton = solo.getString(test_project_package.R.string.login_button);

string.xml file contain (located in the test project):

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="login_button">Sign In to App.</string>
</resources>

Problem is in the returning value. Instead of "Sign In to App." , Java return "res/layout/bottom.xml" . It seems that it is a path from source code of app. that is in the same workspace).

I tried not to use solo:

Resources resources = getInstrumentation().getTargetContext().getResources();
String loginButton = res.getString(test_project_package.R.string.login_button);

Same problem.

What is wrong? Why Java returns an incorrect value?

Answer 1

Partially solved this problem :)

Add the following import in the test project:

import project_package.R;

After that it is possible to use settings from source code. Java returns right parameters.

solo.clickOnButton(solo.getString(R.string.add_account_button));

But! If you want to get parameters from test project and set import like this:

import project_package.test.R;

or just without import Java will return wrong parameter. Don't know why

I found this tip in article Android Testing with the Android Test framework, Robotium, Monkey and Robolectric

Answer 2

I think solo.getString() is not to fetch the strings from String.xml It is to get the strings associated with the views in current activity.

To get the strings from String.xml use the following :

solo.getContext().getString( resId );

in your case -

solo.getContext().getString( R.string.login_button );

should work fine.
