I have some Fragment classes in which I have added some buttons to go from one Fragmen to another Fragmen.
I have commented that for the transitions between Fragment we use FragmentTransaction and instead of getFragmentManager or getSupportFragmentManager that is used getChildFragmentManager
I do not know if I'm doing it right, but it's not working for me, this is the code that does not work for me:
botonSF.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
SegundoF fragment = new SegundoF();
FragmentTransaction ftSF = getChildFragmentManager().beginTransaction();
ftSF.replace(R.id.frame_container, fragment);
ftSF.addToBackStack(null);
ftSF.commit();
}
});
On the other hand, using this other code if I can move from one Fragment to another Fragment, I do not know if in the future it could give any problem by not using FragmentTransaction
botonSF.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
getActivity().getSupportFragmentManager()
.beginTransaction()
.replace(android.R.id.content, new SegundoF())
.addToBackStack(null)
.commit();
}
});
I really do not know why it works, because if you look, in the first code to replace the fragment I use R.id.frame_container instead it's the second code I use android.R. id.content ;
in activity_main.xml
<FrameLayout
android:id="@+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</FrameLayout>
How does this second code work if in the activity_main.xml I have "@ + id / frame_container"? And why does not the first code work?
Then when I show the content of the second Fragment, it stays on top of the menu, it is superimposed on the TabLayout Because the Fragment is shown above the menu, how could I put it below so that it does not cover the menu?
This example video shows what I have said and the problem with the Fragment link
Another problem that I encountered on another occasion is that the fragment is shown one on top of the other, as you can see in this example video.
link
This case is not superimposed on the menu, but the two fragments are shown, as I can avoid that the two fragments are not shown.
