Question

I have this code:

        tvData1 = (TextView)findViewById(R.id.tvData1);
    tvData2 = (TextView)findViewById(R.id.tvData2);
    tvData3 = (TextView)findViewById(R.id.tvData3);
    GetData data= new GetData();
    try {
        SharedPreferences getName = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
        String name = getName.getString("name", "");
        String returned = data.getData(name); //Gets data from internet
        String[] dataSplit = returned.split(",");
        for(int i = 0; i < dataSplit.length; i++){
            String stringData1 = dataSplit[0];
            String stringData2 = dataSplit[1];
            String stringData3 = dataSplit[2];

            tvData1.setText(stringData1);
            tvData2.setText(stringData2);
            tvData3.setText(stringData3);
        }

well, the string gotten from the internet is like this:

"1,2,3 4,5,6"

and where that space is between 3 and 4 actually shows in a new line like:

1,2,3
4,5,6

but basically the result i want is

stringData1 = 1
stringData2 = 2
stringData3 = 3
stringData4 = 4
etc...

instead of:

stringData1 = 1
stringData2 = 2
stringData3 = 3 4

which is what it’s doing now.

also another irrelevant problem I seem to be having is tvData2 will not setText no matter what, even if i do tvData2.setText(“Some Text”);

Answer 1

String‘s split() method takes a regular expression. So possibly you could have a character class in the expression that would split on both commas and new-line characters. Perhaps the following would work. (Edit: Just tested it and it does work for me.)

String[] dataSplit = returned.split("[,\n]");

Another option could be to use the shortcut for white space, to split on all whitespace characters: \s. (Note that you need to escape the \ character:

String[] dataSplit = returned.split("[,\\s]");

Tested and this also works, on the string "1,2,3\n4,5,6".
