package net.sytm.liaoningmobile.controller;

import android.widget.RadioGroup;

import net.sytm.liaoningmobile.R;
import net.sytm.liaoningmobile.base.BaseActivity;

/**

public class LoginController implements RadioGroup.OnCheckedChangeListener {

private BaseActivity activity;

public LoginController(BaseActivity activity) {
this.activity = activity;
initView();
}

private void initView() {
RadioGroup radioGroup = (RadioGroup) activity.findViewById(R.id.switch_btn_id);
radioGroup.setOnCheckedChangeListener(this);
}

@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
