App->activity->custom Dialog Example using Activity to implement a custom dialog boxThe class customdialogactivity itself is nothing special. The key point is its definition in Androidmanifest.xml: android:label=" @string/activity_custom_dialog " Android:theme = "@style/theme.customdialog"> Customdialogactivity uses a custom Customdialog style (Theme). Android apps can use a custom interface style (Theme), Theme as a set of related style definitio

An Android app can contain multiple activity, and an activity can initiate another activity.The activity is managed with a stack structure, and the newly opened activity is stacked on top of the current activity, and the current activity stops running.When an activity stops running, the Android system retains its pre-stop state, and when the user presses the "Back" button, the top activity of the stack is rolled out of the stack and the previous activity moves to the top of the stack and is disp

the service is re-created when Onstartcommand is called, the last intent is not passed in as a parameter, that is, intent=null. Start_redeliver_intent will pass in the last intent that was not processed before being killed.This service is not used as a bind service, so it is implemented by an empty implementation:@Override Public ibinder onbind (Intent Intent) { returnnull;}Finally, to see how to start/stop this service, controller is implemented as the control class for this service, provide

The Reorder activities example has four related activitives:reorderonlaunch, Reordertwo,reorderthree, Reorderfour. Where Reorderonlaunch is the main activity,reorderonlaunch start Reordertwo, Reordertwo starts reorderthree,reorderthree. At this time, the "Back stack" of the activity has the following status:Reorderfour want to start reordertwo again, at this time with two implementation methods, one is to start a new reordertwo above the Recordfour, which is the default behavior of StartActivity
