Trying to take an Array position(toString) and pass that to a new activity, then use that string to select which array to open in the new activity.

Intent launchingIntent = getIntent();
String content = launchingIntent.getData().toString();
setListAdapter(ArrayAdapter.createFromResource(getApplicationContext(), R.array.????, R.layout.main)); `

the R.array.???? needs to be the string that is passed (string content), because that is the name of my array to follow up with.

I can’t find a way to pass the string variable to the name of the array to use.

EDIT: Im trying to get one listView to open up another Listview in the same actvity, closing the prior one.

    the R.array.???? needs to be the string that is passed (string
    content), because that is the name of my array to follow up with.

    Use the getIdentifier() method:

    Intent launchingIntent = getIntent();
String content = launchingIntent.getData().toString(); // this returns the Uri, are you sure you didn't want to get the text from an extra field set in the Intent
int id = getResources().getIdentifier(content, "array", getPackageName());
setListAdapter(ArrayAdapter.createFromResource(getApplicationContext(), id, R.layout.main));

    Im trying to get one listView to open up another Listview in the same
    actvity, closing the prior one.

    I would advise against this because you lose the back button functionality(which may confuse the user). Instead use different activities passing relevant data with Intents or use fragments(especially ListFragments).
