Return button to previous activity with BaseAdapter

I currently have two activities doing HTTP requests.
The first activity contains a CustomList class extends BaseAdapter.
On the second, there is a previous button allowing me to return to the first activity.
Returning to the first activity, I would like to be able to recover the state in which I left it. That is to say to be able to find the information which also come from an HTTP request. I would like to find the data "infos_user" which is in the first activity and all the data in the BaseAdapter.
My architecture is as follows: Activity 0 (HTTP request) -> Activity 1 (with BaseAdapter and HTTP request) -> Activity 2 (HTTP request)
I put all the code because I really don't know how can I do this :/
First activity:
public class GetChildrenList extends AppCompatActivity implements View.OnClickListener {
private ArrayList<Child> childrenImeList = new ArrayList<Child>();
private Button btn_previous;
private ListView itemsListView;

#Override

Intent intent = new Intent(GetChildrenList.this , GetLearningGoalsList.class);

btn_previous = (Button) findViewById(R.id.btn_previous);

tv_signin_success = (TextView) findViewById(R.id.tv_signin_success);
tv_signin_success.setText("Bonjour " + infos_user + "!");
itemsListView = (ListView)findViewById(R.id.list_view_children);
new GetChildrenAsync().execute();
}
class GetChildrenAsync extends AsyncTask<String, Void, ArrayList<Child>> {

#Override

}
#Override

Second Activity:

}
}
}
}
Thanks for your help.

if you want to maintain GetChildrenList state as it is then just call finish() rather than new intent on previous button click as follow
replace in GetLearningGoalsList
#Override
public void onClick(View v) {
Intent myIntent = new Intent(GetLearningGoalsList.this, GetChildrenList.class);
myIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(myIntent);
return;
}
with
#Override
public void onClick(View v) {
finish();
}

Why OnItemClickLIstener Is Not Work for PullToRefreshLIstView?

I am Using following code:-

I have define OnItemClickLIstener inside setAllContrill method but it is not working.listView is unclickable anyone suggest me .I am using github pulltorefresh code .I unable to find out what is issue because in other places it is working..

Try: `
objlistview.getRefreshableView().setOnItemClickListener(new OnItemClickListener...)

getRefreshableView() won't help, because setOnItemClickListener() in PullToRefreshListView is just a pass-through method:
public void setOnItemClickListener(OnItemClickListener listener) {
mRefreshableView.setOnItemClickListener(listener);
}
I had the same problem, and it turned out that I had clickable element in item layout. After making this element non-clickable it began to work.
