Question

I was using AsyncTask class… My objective is to have a list and when search button is clicked make “Searching…” string appear in the list while searching… For that I tried to instansiate an adapter inside onPreExecute()

private class SearchTask extends AsyncTask<Void, Void, Void>{

        protected void onPreExecute() {
            String[] strings = new String[] { "Searching" };
            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, strings);


            mSearchButton.setEnabled(false);
        }
                //rest of methods
}

The compiler gives me an error in new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, strings);

And it says:The constructor ArrayAdapter<String>(SearchActivity.SearchTask, int, ArrayList<String>) is undefined

Any way to solve this?

Incorrect parameters. Take a look at documentation.

ArrayAdapter<String> adapter = new ArrayAdapter<String>(YourActivity.this,      
                   android.R.layout.simple_list_item_1, strings);
