Answer 1

Simple..

Considering signupText, loginText as object.

1. Store sign up text in preference. I have used a separate class for preference. For more how to write preference in separate class and use it means, please refer here for preference..

store signupText in preference.

mPreferenceData.storeInPreference("signup",     
signupText.getText().toString().trim()));

in login page

String signUpText = mPreferenceData.getStoreInPreference("signup");
//now you will have data in signupText
button.setOnClickListener(new View.OnClickListener(){        
    if(loginText.getText().toString().trim().equalsIgnoreCase(signUpText)){
        // now loginText whatever data that matches with signUpText will make to login successful
    } else{
        //failure
    }

});
