I have an android app with an activity and one fragment. Two fragments are created and overlap when the activity restore after configuration change but I don't know why. Can anybody give me a clue? I'm not using ViewPager. I've seen this Overlapping Fragments when resuming Activity is like my problem but don't understand the solution Thanks in advance
This is the activity where DetalleProductoFragment fragment is created. It has more code but I've left important
public class ContinuarInformeActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mBinding = DataBindingUtil.setContentView(this, R.layout.activity_continuar_informe);
// get fragment manager
myChildToolbar =
findViewById(R.id.toolbarinf);
setSupportActionBar(myChildToolbar);
// Get a support ActionBar corresponding to this toolbar
ActionBar ab = getSupportActionBar();
// Enable the Up button
ab.setDisplayHomeAsUpEnabled(true);
// add
nviewModel =
new ViewModelProvider(this).get(NuevoinformeViewModel.class);
loadData(savedInstanceState);
//reviso si es edicion y ya tengo info en temp
ultimares=dViewModel.getUltimoTemp();
if(ultimares!=null) //is edition
{
preguntaAct=dViewModel.inftempToReac(ultimares);
if(preguntaAct.getTabla().equals(ultimares.getTabla())){
//si es la misma
