How to set ArrayAdapter properly in Android

I'm trying to make a ListView in Android with a dynamic field. First, I tried to set it up using static field which is shown below (String[] chars)

String[] chars = {"TEST"};
setListAdapter(new ArrayAdapter<String>(this,R.layout.resultlist,chars));

it gives me error The constructor ArrayAdapter<String>(ViewTranslationsList.GrabURL, int, int) is undefined. Where's the problem?

I want to add items to the chars array before I set up ArrayAdapter in for cycle.

Thanks

im not about your problem, but if you dont now about standard layout in android.

  l.setListAdapter(new ArrayAdapter<String>(SomeActivity.this,android.R.layout.simple_list_item_1,chars));

or

l.setListAdapter(new ArrayAdapter<String>(SomeActivity.this,android.R.layout.simple_list_activated,chars));

or 

l.setListAdapter(new ArrayAdapter<String> (SomeActivity.this,android.R.layout.simple_list_item_multiple_choice,chars));
l.setOnChoise(LISTVIEW.SET_MULTICHOISE_MODE);

read about standard layout. http://developer.android.com/reference/android/R.layout.html

here this is ViewTranslationsList.GrabURL

ListView l = (ListView)findViewById(R.id.some)
l.setListAdapter(new ArrayAdapter<String>(SomeActivity.this,R.layout.resultlist,chars));

you have to pass Context, ViewTranslationsList.GrabURL is not Context

It looks like you are not inside your Activities context when you are calling your ArrayAdapter constructor. Try to change it like this:

setListAdapter(new ArrayAdapter<String>(yourActivityName.this,R.layout.resultlist,chars));

Though that may not be your only problem because based on the error it seems to think that chars is an int for some reason.

It looks like you're doing this inside an inner class (since the error is mentioning ViewTranslationsList.GrabURL. If that is truly the case, try doing this:

setListAdapter(new ArrayAdapter<String>(ViewTranslationsList.this,R.layout.resultlist,chars));
