使用 SharedPreferences 读写数据

public class SharedPreManager {private Context mContext;public SharedPreManager(Context context){mContext = context;}/** * 写数据 */public void writeData(String name,int age){SharedPreferences preferences = mContext.getSharedPreferences("xmlname",Context.MODE_PRIVATE );Editor editor = preferences.edit();editor.putString("name",name);editor.putInt("age",age);editor.commit();}/** * 读数据 */public Map<String,String> readData(){Map<String,String> params = new HashMap<String,String>();SharedPreferences preferences = mContext.getSharedPreferences("xmlname",Context.MODE_PRIVATE );params.put("name", preferences.getString("name", ""));params.put("age", String.valueOf(preferences.getInt("age", 0)));return params;}}
