Get the position of selected checkbox and store it in arraylist and then compare the position with the selected position list in getView method. If the list is having that position set the checkbox checked else make it uncheck.

I think removing if(view==null) will do the job.Try it , like in the code below:
#Override
public View getView(int position, View view, ViewGroup parent) {
LayoutInflater inflater =(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view=inflater.inflate(R.layout.grid_parent_cat_individual_items, null);
TextView textView = (TextView) view.findViewById(R.id.textView);
textView.setText(strName[position]);
TextView textView1 = (TextView) view.findViewById(R.id.textView1);
textView1.setText(strName1[position]);
TextView textView2 = (TextView) view.findViewById(R.id.textView2);
textView2.setText(strName2[position]);
TextView textView3 = (TextView) view.findViewById(R.id.textView3);
textView3.setText(strName3[position]);
TextView textView4 = (TextView) view.findViewById(R.id.textView4);
textView4.setText(strName4[position]);
TextView textView5 = (TextView) view.findViewById(R.id.textView5);
textView5.setText(strName5[position]);
TextView textView6 = (TextView) view.findViewById(R.id.textView6);
textView6.setText(strName6[position]);
return view;

How to refresh list view by calling notifyOnDatasetChanged with in base adapter

I am having the list view with buttons in my fragment class which was populated using the custom adapter.When the button which was present inside the list view was pressed i want to remove that item.Here i used the notifyDataSetChanged when ever the button clicks from my adapter class but it does not reflect any result.can any one tell me how to update the list view from adapter class
this is the code i had written inside my adapter class after clicking button
remove.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
notifyDataSetChanged();
}
});

I didn't find the code that changes the "List objects" content.
You can try this:

objects.addAll(query(......));
mAdapter.notifyDataSetChanged();

NotifyDataSetChanged on gridview not working - Android

I am working with GridView. I want to update GridView on some basis. But notifyDataSetChanged() method is not working.
I am selecting tables on basis of section name. When I select section name very first time than I got tables of that section. But when I go to sections fragment again and select diff. section than I get previously selected tables only. That means notifyDataSetChanged() is not working.
What I have tried is like below.

At last I got the solution.
I have done like below...
I was maintaining a FLAG called getTableStatus to get the tables of particular section. If the value of getTableStatus is FALSE than only TableStatusAsync is called. At first selection of section, tables are coming from web service and those tables are being inserted in DB.
On second time, selecting of SECTION, tables are coming from DB not from web service. And tables are coming from DB are of previously selected SECTION. So, there is nothing to do with notifyDataSetChanged().
I have just change the FLAG value to FALSE by calling pref.setTableStatus(false); on selection of SECTION. Now, TableStatusAsync is called every time when you change your selection of SECTION.
Modified Code...
TableScreenSectionwiseActivity.java
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
pref.setSectionId(view.getTag().toString());
pref.setTableStatus(false);
pref.setTableServiceStatus(false);
Fragment fragment = new TableScreenActivity();
ReplaceFragment.getReplaceFragment(getActivity(), fragment, "");
}

It is display nothing because you do not fill up the dataset you want to display. You create the Adapter in onCreate but at the time the dataset is empty. Imo you should change the Adapter constructor from
public CountryAdapter(Context paramContext, ArrayList<String> paramArrayList) {
to
public CountryAdapter(Context paramContext, ArrayList<HashMap<String, String>> paramArrayList) {
and when onPostExecuted is called, you create a new CountryAdapter and submit it to the ListView. Of course you have to adjust your Adapter in order to reflect the changes of the Adapter's constructor
