Android getting unchecked checkbox in checklist after search in edittext

Android getting unchecked checkbox in checklist after search in edittext - android

I have checklist with search functionality(used edittext). When I use it to search it shows filtered items so that I can make the selection that I want, it works properly. However, the checked items become unchecked when the search functionality reloads the list. I want the items selected before the search to remain selected. How can I fix this?
Here is my code:
public class Lab extends Fragment {
Button mViewBtn,msaveBtn;

ListView recycles the views every time its associated edit text's value is changed. That's why the Check-boxes does not retain their states.
To accomplish your task:
Store the checked items in an array.
When you click any checkbox in the listview, change the value of that particular item in the array.
Inside your getView method, check or uncheck the Check-boxes by reading the values from the array.
That way your checkboxes will retain their states. I hope this is clear.

I understand your problem. Let's make a small change in your adapter.
public class MyCustomAdapter extends ArrayAdapter<States> {
public ArrayList<States> stateList;
public MyCustomAdapter(Context context, int textViewResourceId, ArrayList<States> stateList)
{
super(context, textViewResourceId, stateList);
this.stateList = new ArrayList<States>();
this.stateList.addAll(stateList);
this.getSelectedList();
}
private void getSelectedList()
{
pref = context.getSharedPreferences("MYPref", Context.MODE_PRIVATE);
String text = pref.getString("key","");
List<String> selectedList = Arrays.asList(text.split(","));
for (State state: this.stateList) {
if (selectedList.contains(state.getName())) {
state.setSelected(true);
}
}
}
...
}

for (int i = 0; i < stateList.size(); i++) {
States state = stateList.get(i);
if (list.contains(state.getName()))
state.setSelected(true);
}
Delete these lines
if (sb.length() > 0 ) {
str = sb.substring(0, sb.length()-1);
}
in checkButtonClick.
str = sb.toString();
pref.edit().putString("key", str).apply();

Listview having ediitext

I have a sectioned Listview having some edittexts. If I click on that edittext for the first time, the softkeyboard works fine.

02-12 14:51:04.164: I/Editor(18219): setup window support handles

have you tried setting this property in your listview
android:descendantFocusability="beforeDescendants"

I will suggest you to listen activity onfocusChange rather then listening every editbox this might remove flicker (rather executing all editbox onfcoucs change methods its been capture once.)
#Override
public void onFocusChange(View v, boolean hasFocus) {
switch(v.getId()){
case r.id.editText_id:
break;
}
}
