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;
}

}
