Question

I have a String[] that contains number of strings, what I’m trying to do is set a ProgressBar’s progress according to which string is used.

For example, I have already determined number of strings and set max progress of progress bar accordingly; here is the list:

 "zero one two three four five six seven eight nine...."

..

 String[] cpu0freqslist = cpu0freqs.split("\\s");
 countcpu0 = cpu0freqslist.length;

..

 ProgressBar cpu0progbar = (ProgressBar)findViewById(R.id.progressBar1);
 cpu0progbar.setMax(countcpu0);

But now I need to set the progress of progressbar according to the item that is used, and I don’t know how to get item position.

So if I want to set a progress bar to the position of item five (in this case it would be 6) how can I do that – how can I get the position of item five?

Answer 1

essentially what you’re looking for is a indexOf(…) …

since arrays don’t have it, you’ll have to search thru it to find the desired string. so something like this (feel free to optimize)

 public int indexOfString(String searchString, String[] domain)
 {
     for(int i = 0; i < domain.length; i++)
        if(searchString.equals(domain[i]))
           return i;

     return -1;
 }

Then again, if you dynamically fetch your String[] data, it would be wiser to use an ArrayList and just invoke list.indexOf(myString);
