记录一下我的Android项目里的基类的的基本设计
来源：互联网 发布：淘宝虚假广告怎么投诉 编辑：程序博客网 时间：2024/06/02 06:54
BaseActivity基类里面的UI设计通常有以下一个部分：1.title的控制 2.加载的控制 3.主体内容的显示 4.没网或是没数据时的异常显示
另外还有Activity跳转的控制。
先看看我的基类的xml布局：

所以在BaseActivity里面重写了onBackPressed:
@Override public void onBackPressed() { ActivityAnim.finshActivity(this); }阅读全文
