Replace Fragments In FrameLayout - Best Practice

In this tutorial, you will learn how to replace fragments in the FrameLayout layout in Android.

You should always add, remove, and replace your fragments problematically. As such I suggest you replace your “TitleFragment” fragments with containers such as FrameLayout. I had to use android.support.v4.app.Fragment; instead of android.app.Fragment;. This is the code I got it to work with:


<FrameLayout
        android:id="@+id/fragment_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/view"
        android:layout_marginTop="@dimen/medium_margin">
</FrameLayout>

<FrameLayout

android:id="@+id/fragment_container"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:layout_below="@+id/view"

android:layout_marginTop="@dimen/medium_margin">

</FrameLayout>

setFragment method called from displayView method,


protected void setFragment(Fragment fragment) {
    android.support.v4.app.FragmentTransaction trans = getSupportFragmentManager().beginTransaction();
    trans.replace(R.id.fragment_container, fragment);
    trans.commit();
}
