FragmentOperator

A library to make managing Android fragment backstack easier!

Usage

Add to your project build.gradle file:

dependencies {
  implementation 'com.tubitv:fragmentoperator:1.1'
}

Single Activity Backstack Usage

Your Activity for Fragment operation has to extend from FoActivity. All your fragments have to extend from FoFragment.

When your Activity is ready, you need register current active Activity.

  FragmentOperator.INSTANCE.setCurrentActivity(CURRENT_ACTIVITY)

When you need to show a Fragment, use APIs in FragmentOperator:

  FragmentOperator.INSTANCE.showFragment

• clearStack: Flag for clearing all previous backstack
• skipOnPop: Mark new fragment to be skipped when pop backstack
• containerId: Res ID for where the fragment should be loaded to

When you need to set a Fragment class to be single instance in backstack, just add annotation SingleInstanceFragment to your Fragment class.

  @SingleInstanceFragment
  public class CategoryFragment {}

Tabs Navigation Usage (Fragment child backstack)

FragmentOperator also supports another level of backstack navigation along with Activity backstack. It fully supports iOS tabs style navigation, which means it keeps and maintains multiple child Fragment backstacks.

Same here, to use FragmentOperator, you need make sure your Activity extend from FoActivity and Fragment extend from FoFragment.

You need build a Fragment to host all tabs and implement TabsNavigator.

Then for any fragments you want to display on a specific tab, you just add annotation TabChildFragment and put tab index. When you show fragment instance with

  FragmentOperator.INSTANCE.showFragment

FragmentOperator will automatically switch to correct tab and display Fragment instance on that tab.

FragmentOperator also supports popping all the way back to root child fragment, just like iOS.

Please refer demo project for how to use tabs navigation.
