ArrayList into ArrayAdapter

I'm trying to put an arraylist method into an arrayadapter but i am unable to do so. I am getting The constructor ArrayAdapter<String>(new Runnable(){}, int, ArrayList<RetrieveInternet>) is undefined

ArrayAdapter

            ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, getPackages());

Arraylist method:

private ArrayList<RetrieveInternet> getPackages() {
    ArrayList<RetrieveInternet> apps = getPermissions(true); /* false = no system packages */
    final int max = apps.size();
    for (int i=0; i<max; i++) {
        apps.get(i);
        Log.e("TAG", apps.get(i).toString());
    }
    return apps;
}

First parameter of ArrayAdapter constructor should be Context not Runnable. You are probably setting your adapter from within some Runnable so you cannot use this reference because it pointing at that Runnable instance. You should change this line:

ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, getPackages());

into this:

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

The main difference is first parameter - YourActivity.this which is reference to your activity in which you are setting your adapter.

Obviously you are creating your adapter in a Runnable (in run() method), that's why this refers to the Runnable, not to a Context. Try to use YourActivity.this instead of this.
