Android Xml检查Web服务是否返回true或false

Question

I am working on determining if a stream is live or not. I have a preexisiting file that does that ( http://www.calvaryccm.com/ServiceTimes.asmx/IsServiceTime ). This is what it returns when the stream is inactive:

<boolean xmlns="http://tempuri.org/">false</boolean>

When the stream is active it returns this:

<boolean xmlns="http://tempuri.org/">true</boolean>

I need help creating a xml reader to check if the webservice returns true or false. Thank you for your help.

I recently did the same thing on iOS and this is how I checked the XML.

NSError * error = nil;
NSString * responseString = [NSString stringWithContentsOfURL:[NSURL        URLWithString:@"http://www.calvaryccm.com/ServiceTimes.asmx/IsServiceTime"] encoding:NSUTF8StringEncoding error:&error];    

NSRange range = [responseString rangeOfString : @"true"];

if (range.location != NSNotFound) {
    NSLog(@"%@", responseString); 
    /// Handle active content.
   hiddenVideo.hidden = FALSE;
    hiddenAudio.hidden = FALSE;
    noService.hidden = TRUE;
    }
    else {
        NSLog(@"%@", responseString);
        // Inform user that the content is unavailable
       hiddenVideo.hidden = TRUE;
        hiddenAudio.hidden = TRUE;
        noService.hidden = FALSE;
        // Inform user that the content is unavailable
       UIAlertView *alert = [[UIAlertView alloc]
                              initWithTitle: @"Live Service"
                             message: @"There is no service going on at this time"
                             delegate: nil
                             cancelButtonTitle:@"OK"
                             otherButtonTitles:nil];
        [alert show];
        [alert release];
        HasShownAlert = TRUE; //let the other event know that the alert has already been shown.
   } 

Is there a way to do something similar in Android?

Answer 1

You have to parse your xml. After parsing your xml you can get Boolean value true or flase. After that you can use that value in application as per your use.

For parse the XML in android XML PULL parser is best way. Using that you can parse your xml.

The javax.xml.* packages are available on android devices.
