SimpleFragmentManager

Simplified handling of fragments in android application by using wrapper class around FragmentManager and simple tag stack.

Detailed explanation is in this blog post

Installation

Gradle

implementation 'com.bajicdusko:fragment-manager:1.0.4'

or

implementation 'com.bajicdusko:kotlin-fragment-manager:1.0.4'

Usage example

To simplify the setup, few super classes are created: SFMActivity, SFMFragment and FragmentChannel. By extending these three classes you should be ready in no time.

Create new communication interface by extending FragmentChannel

interface ExampleFragmentChannel : FragmentChannel {
    fun openSecondFragment()
}

Each new fragment handled by SimpleFragmentManager should extend SFMFragment<>

class FirstFragment : SFMFragment<ExampleFragmentChannel>() { 

    ...
    
    fun onButtonClick(){
        fragmentChannel?.openSecondFragment()
    }
}

By creating new activity, just extend SFMActivity

class HomeActivity : SFMActivity(), ExampleFragmentChannel {

    override fun getFrameLayoutContainerId(): Int = R.id.activity_home_fragment_container

    override fun onCreate(savedInstanceState: android.os.Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_home)
        simpleFragmentManager.enableLogs(true)
        simpleFragmentManager.addFragment(FirstFragment.newInstance())
    }
    
    override fun openSecondFragment(){
        simpleFragmentManager.replaceFragment(SecondFragment.newInstance())
    }
}

This is what happens in the background
