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?
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);
You can use the Arrays
utility class:
List<String> list = Arrays.asList(new String[] {"First", "Second", "Third"});
int index = list.indexOf("Second"); // 1
cpu0freqslist[5]
这对你有帮助吗?
Ok let me break your query into parts...
String[] arr = {"First","Second","Third"}; // String array with 3 elements
for(int i=0 ; i<arr.length ; i++){
int j = i ; // Position of the element
String s = a[i] ; // Element Itself
System.out.println("The "+i+" element is "+s);
}
