I am making a list with editable options, everything marks well when I navigate down but, when I return to upload all my information is deleted, will it be that I am updated on my information model or how could I avoid this case?

try to make the code as understandable as possible,
I had never worked with a daptor that was editable, this logic always worked for me when I only had to show info, should it be done in some other way?
in your code, i don't see that you would update the adapter after changing the data for example call such methods notifyDataSetChanged(), notifyItemChanged(item_position) etc, so after scroll ListView the adapter will have old data. For example this code
Correct version
about these fields
their display should depend on the value that is in the model, so when you added
listaObjetos.get(i).setPresente(true);and callnotifyItemChanged(i)will be calledgetView()method and these fields will change depending on this conditionalso instead of
BaseAdapterit is better to useRecyclerViewwithRecyclerView.Adapter. About saving information from fields, you useaddTextChangedListeneri think this is bad, because every time after tap you need to update the model.It's better to add handling to press DONE button on keyboard, so you need to update the model and adapter once.
