package com.example.sharedpreferences;



import java.util.Map;



import com.eboy.service.PreferencesService;



import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.view.View;

import android.widget.EditText;

import android.widget.Toast;



public class MainActivity extends Activity {

    private EditText edtName;

    private EditText edtAge;

    private PreferencesService service = null;

    

    

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        edtName = (EditText)findViewById(R.id.name);

        edtAge = (EditText)findViewById(R.id.age);

        service = new PreferencesService(getApplicationContext());

        //软件启动时加载保存的参数

        Map<String, String> params = service.getPreferences();

        edtName.setText(params.get("name"));

        edtAge.setText(params.get("age"));

    }



    @Override

    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.activity_main, menu);

        return true;

    }

    

    /**

     * 保存参数,OnClick配置在xml文件中

     * @param v

     */

    public void save(View v){

        String name = edtName.getText().toString();

        String age = edtAge.getText().toString();        

        service.save(name, Integer.valueOf(age));

        Toast.makeText(getApplicationContext(), "成功".toString(), Toast.LENGTH_SHORT).show();

    }
