package com.example.androidtest;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.RadioGroup;

public class MainActivity extends Activity {

	Restaurant r = new Restaurant();
	
	public void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		Button save = (Button)findViewById(R.id.save);
		save.setOnClickListener(onSave);
	}
	
	private View.OnClickListener onSave = new View.OnClickListener() {
		
		@Override
		public void onClick(View v) {
			// TODO Auto-generated method stub
			EditText name = (EditText)findViewById(R.id.name);
			EditText address = (EditText)findViewById(R.id.addr);
			
			r.setName(name.getText().toString());
			r.setAddress(address.getText().toString());
			RadioGroup types = (RadioGroup)findViewById(R.id.types);
			switch(types.getCheckedRadioButtonId()) {
			case R.id.sit_down:
				r.setType("sit_down");
				break;
			case R.id.take_out:
				r.setType("take_out");
				break;
			case R.id.delivery:
				r.setType("delivery");
				break;
			}
		}
	};
	
}


class Restaurant
{
	private String name = "";
	private String address = "";
	private String type = "";
	
	public String getName()
	{
		return name;
	}
	
	public void setName(String name)
	{
		this.name = name;
	}
	
	public String getAddress()
	{
		return address;
	}
	
	public void setAddress(String address)
	{
		this.address = address;
	}
	
	public String getType()
	{
		return type;
	}
	
	public void setType(String type)
	{
		this.type = type;
