Okay. So this is a very old question and has great answers from that time. But a lot has changed since then.

Now, in 2020, if you are working with Kotlin and want to change the fragment then you can do the following.

1. Add Kotlin extension for Fragments to your project.

In your app level build.gradle file add the following,

dependencies {
    def fragment_version = "1.2.5"

    // Kotlin
    implementation "androidx.fragment:fragment-ktx:$fragment_version"
    // Testing Fragments in Isolation
    debugImplementation "androidx.fragment:fragment-testing:$fragment_version"
}

2. Then simple code to replace the fragment,

In your activity

supportFragmentManager.commit {
    replace(R.id.frame_layout, YourFragment.newInstance(), "Your_TAG")
    addToBackStack(null)
}
