Question

I have a Activity that pulls an Array from the previous Activity. I can use this code below which gets the Array from the previous Activity and puts it into a TextView.

Update using initWheel(R.id.passw_1, names.toArray(new String[names.size()])); fixed the problem

ArrayList<String> names = intent.getStringArrayListExtra("KEY");

    TextView et2 = (TextView) findViewById(R.id.editText2);
    et2.setText("");
    if (names.size() > 0) {
        for (String str : names) {
            et2.append(str + "    ");
        }
    }

This works fine but is not what I need exactly. Instead of it populating a TextView I need it to fill a String which is like this

initWheel(R.id.passw_1, "ArrayList Here");

I have another which will be set by default in the code that looks like this and I need the array to populate the one above in the same format:

initWheel(R.id.passw_2, new String[] { "Foo", "Bar" });

I think you are asking about getting string array from arraylist, if so please use following method:

String[] strArr = list.toArray();
