Answer 1

You can use nested fragment. For example in your General fragment you can load ChildFragment1 at the beginning, then when after the button click replace it with ChildFragment2.

fragment_general.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             android:layout_width="match_parent"
             android:layout_height="match_parent"
             android:orientation="vertical">

    <View
        android:id="@+id/view_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</FrameLayout>

GneralFragment.java

//Call this at the beginning
private void loadChildFragment1(){
    getChildFragmentManager()
                    .beginTransaction()
                    .replace(R.id.view_container,
                            new ChildFragment1()
                    .commit();
}

//Call this after the click
private void loadChildFragment2(){
    getChildFragmentManager()
                    .beginTransaction()
                    .replace(R.id.view_container,
                            new ChildFragment2()
                    .commit();
}
