跳过两者之间的活动并达到android中的特定活动

Question

I have following app structure

• MainFragmentActivity
  • Notification Fragment
  • MainFragment
  • ChatFragment
  • So on etc.

I also have set a broadcast on all "Activities" That will show a popup if any Push notification is arrived.

The popup has two options, View or Ok.

Now let's say i am on ChatFragment , from there i go to Chat Contacts List ( Activity) Then on a ChatScreen(Activity) then on ProfileScreen(Activity) of User

The Stack of Activities will be like

MainFragmentActvity -> ChatContactsList -> ChatScreen -> ProfileScreen

What i want is, when i click on "View" on ProfileScreen it should remove all stack activities and take back to MainFragmentActivity and replace its Current Fragment with NotificationFragment.

I can do finishAffinity() Restart the app and put MainFragment but i want to support 16- APIS to.

Flag Clear Top will remove MainActivity and i do not want to restart it because then it has to call a lot of apis

I do not want to put NO History FLAG because i need to put All other activities in History. What can i do here .

Also i do not want to put startActivityForResult it would be so complex. Any ideas would be appreciated

Answer 1

What I understood from your explaination is, you want to create wizard like scenario to control the activities flow at run time. (Wizard means, for example, installation window(wizard) of application on microsoft windows)

1. For that, there is already developed library by Nimrod Dayan , called WizarDroid .

   Here is the link for home page of the same, WizarDroid

   Try it out, its good.

or

2. You can use view pager (WizarDroid is also built on view pager)
