How to count symbol in string and split accordingly and set in Textview?

Question

I have an app in which i have a string in which i have to count symbol and split that string accordingly and set it in textview.

code:-

int commas = 0;
String data = "Note:MRP shown , rates.The tariff plans are subject to change .Plans have been provided for information purposes only.";
for (int i=0; i < data.length(); i++) {
    if (data.charAt(i) == ".") {
        commas++;
    }
}

Here is a one-liner you could use:

int commas = data.split("\\.").length - 1;

If you actually need to parse your text into separate sentences, you could do something similar:

String[] parts = data.split("\\.");
StringBuilder text = new StringBuilder("");
for (int i=0; i < parts.length; ++i) {
    if (i > 0) text.append("\n");
    text.append(" * " + part[i] + ".");
}

TextView yourTextView = (TextView) findViewById(R.id.tv_id);
yourTextView.setSingleLine(false);
yourTextView.setText(text.toString());

Note here that I am using HTML inside the TextView to get newlines after each sentence.

but how to set it in Textview – Niraj Sep 01 '17 at 04:12
But how to set it in textview because i have to set textview based on index at runtime – Niraj Sep 01 '17 at 04:13
Because i dont know the index may be it may increase at runtime – Niraj Sep 01 '17 at 04:14
Also i want to add * before every line of textview – Niraj Sep 01 '17 at 04:20
It is working but it always set "Plans have been provided for information purposes only" in Textview – Niraj Sep 01 '17 at 04:24
Sorry, let me edit this. I could not test anything. One minute. – Tim Biegeleisen Sep 01 '17 at 04:25
sure take your time – Niraj Sep 01 '17 at 04:25
I made another update, give it a try and leave feedback if necessary. – Tim Biegeleisen Sep 01 '17 at 04:32
No, that shouldn't be happening. What is the value of `text` in your code right before we add that the to the `TextView`? Is it a string? – Tim Biegeleisen Sep 01 '17 at 04:36
Another typo, use this instead: `text.append(" * " + part[i] + ".");` ... by the way, I'm not setup right now to easily test my code – Tim Biegeleisen Sep 01 '17 at 04:43
