How to continuously update textView with a different delay parameter

I'm pretty new to Java and Android, and now I'm coding some application, which takes a text from ACTION.SEND and display it word by word in a TextView.

I have a method, which returns Spanned text, and I want to continuously update it in my TextView and implement some actions, such as pause or resume. I've already implemented the activity using this guide, but when I simply iterate over the list of words like this: 

for (int i = 0; i < listSize; ++i){
   ((TextView) layout.findViewById(R.id.textView).setText(someText);
   Thread.sleep(1000 * coefficient);
}

the application shows only the last element of the array(when the cycle is finished). Could you advise some technique to implement this properly?

The Problem is that you'er blocking the UI-Thread with your sleep method. Try using a Handler (link to doc) and its method postDelayed (here).
