申请开始

01-07 17:30:55.178: E/ASE(11253): RouteListActivity.onCreate

01-07 17:30:55.208: E/ASE(11253): RouteListActivity.onResume

开始第二次活动 

Intent intent = new Intent(getBaseContext(), PointListActivity.class);
startActivity(intent);

01-07 17:30:57.948: E/ASE(11253): RouteListActivity.onPause

01-07 17:30:57.948: E/ASE(11253): PointListActivity.onCreate

01-07 17:30:57.958: E/ASE(11253): PointListActivity.onResume

开始第三个活动 

Intent intent = new Intent(getBaseContext(), PointActivity.class);
startActivity(intent);

01-07 17:30:59.258: E/ASE(11253): PointListActivity.onPause

01-07 17:30:59.268: E/ASE(11253): PointActivity.onCreate

01-07 17:30:59.278: E/ASE(11253): PointActivity.onResume

按回

01-07 17:31:00.858: E/ASE(11253): PointActivity.onPause

如果以前是 PointListActivity 为什么要恢复 RouteListActivity

01-07 17:31:00.868: E/ASE(11253): RouteListActivity.onResume

按回

01-07 17:35:42.858: E/ASE(11253): RouteListActivity.onPause

为什么现在 PointListActivity 恢复

01-07 17:35:42.858: E/ASE(11253): PointListActivity.onResume
