在任意位置获取应用程序Context

1.

    private static MyApplication instance;    public static MyApplication getInstance() {        return instance;    }    @Override    public void onCreate() {        // TODO Auto-generated method stub        super.onCreate();        instance = this;    }}

2.在manifest中<application>中加入name="mypackage.MyApplication"

3.在任意类中使用MyApplication.getInstance()来获取应用程序Context了。
