我的Android应用程序出现此问题
我现在已经挣扎了一段时间,并经历了很多类似的线程,但从未真正解决过它。我没有设法重建我自己的崩溃,但我得到其他用户的崩溃报告
以下是崩溃报告:
java.lang.NumberFormatException: -
at org.apache.harmony.luni.util.FloatingPointParser.initialParse(FloatingPointParser.java:149)
at org.apache.harmony.luni.util.FloatingPointParser.parseDouble(FloatingPointParser.java:281)
at java.lang.Double.parseDouble(Double.java:318)
at polis.koll.HelloMapView.loadallmarkers(HelloMapView.java:665)
at polis.koll.HelloMapView.access$10(HelloMapView.java:611)
at polis.koll.HelloMapView$6.run(HelloMapView.java:587)
at java.lang.Thread.run(Thread.java:1027)
这是我的代码,最后一行似乎是一个产生错误
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
/** Send URL to parse XML Tags */
URL sourceUrl = new URL(
"http://www.mysite.com/xml.php");
/** Create handler to handle XML Tags ( extends DefaultHandler ) */
MyXMLHandler myXMLHandler = new MyXMLHandler();
xr.setContentHandler(myXMLHandler);
xr.parse(new InputSource(sourceUrl.openStream()));
} catch (Exception e) {
//System.out.println("XML Pasing Excpetion = " + e);
}
sitesList = MyXMLHandler.sitesList;
gotsnr = "";
gotmarkers = 0;
LocationOverlay locationOverlay = new LocationOverlay(mapView, getResources().getDrawable(R.drawable.polis), mContext);
if (sitesList !=null){
for (int i = 0; i < sitesList.getSnr().size(); i++) {
gotsnr = sitesList.getSnr().get(i);
gotmarkers = (i);
//if (gotsnr !=""){
if (sitesList.getLat().get(i).equalsIgnoreCase("")||sitesList.getLat().get(i).equalsIgnoreCase(null)){
// Empty, do nothing
} else{
GeoPoint point = new GeoPoint( new Double(Double.parseDouble(sitesList.getLat().get(i)) * 1e6).intValue() , new Double(Double.parseDouble(sitesList.getLng().get(i)) * 1e6).intValue());
* 在下面编辑回复@kcoppock
这可以解决这个问题吗?
double dlat = 0;
double dlng = 0;
if (sitesList.getLat().get(i) !=null && !"".equals(sitesList.getLat().get(i)) ){
try {
dlat = Double.parseDouble(sitesList.getLat().get(i));
} catch (NumberFormatException e) {
//System.out.println(e.getMessage());
}
}
if (sitesList.getLng().get(i) !=null && !"".equals(sitesList.getLng().get(i)) ){
try {
dlng = Double.parseDouble(sitesList.getLng().get(i));
} catch (NumberFormatException e) {
//System.out.println(e.getMessage());
}
}
if (dlat !=0 && dlng !=0){
GeoPoint point = new GeoPoint( new Double(dlat * 1e6).intValue() , new Double(dlng * 1e6).intValue());
答案 0 :(得分:2)
你首先没有处理NumberFormatException
,即使你没有崩溃,这也是不好的做法。将该行拆分,首先解析双打,并确保捕获NumberFormatException
并适当处理它(例如,抛出警告对话框,放置默认值等),以防出于某种原因{{1}中的值1}}或getLat()
不可解析,这在这些情况下显然正在发生。
getLon()
