Answer 1

Try This, It's work on my application

//validation controls
public boolean Validatioin() {
    if (first_name.getText().toString().length() <= 0) {
        first_name.setError(getString(R.string.valid_first_name));
        return false;
    } else if (lest_name.getText().toString().length() <= 0) {
        lest_name.setError(getString(R.string.valid_first_name));
        return false;
    } else {
            strFirstName = first_name.getText().toString();
            strLastName = lest_name.getText().toString();
            return true;
        }
    }
}

// interface

public interface user_details {
    void userDetails(String firstName,String 
    Lastname);
}

// in Adapter class

userDetails.userDetails(strFirstName,strLastName);

// constructor

private userDetails userDetails;
public adapterName(Context context,userDetails userDetails)
{
    this.userDetails = userDetails;
}
