Question

What I’m doing is building an Android app that receives a string using a php script which I can do, but what I can’t do is then split that string up using the “\n” and then use that to create an AlertDialog.

I’m recieving this string;

    String list = "test 1\ntest 2\ntest 3";

I’m then trying to then pipe that into an array using the below. I know I’m miles off but can’t seem to find anything about it, could someone point me in the right direction?

    String[] tokens = test.split("\n"); 

    final CharSequence[] items = {tokens};

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Pick a color");
    builder.setItems(items, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int item) {
            Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show();
        }
    });
    AlertDialog alert = builder.create();

    alert.show();

Answer 1

Why are you creating a new array for the CharSequence? You can just set the tokens array as items:

final String[] tokens = test.split("\n"); 
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Pick a color");
    builder.setItems(tokens, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int item) {
            Toast.makeText(getApplicationContext(), tokens[item], Toast.LENGTH_SHORT).show();
        }
    });
    AlertDialog alert = builder.create();
