IllegalArgumentException：解析错误java.util.Date

Question

I'm getting low rating on the app I published recently. The app crashes sometimes and users report this type of error:

I'm getting reported this same error pretty frequently:

Parse error: Mon, 09 M

Parse error: Sat,

Parse error: Fri, 06 

Parse error: Thu,

Parse error: Tue, 03 May 2016 11

I really don't know how to handle this problem. I'm trying to display the time a news article was published.

NestedListView :

public class NestedListView extends ListView implements View.OnTouchListener, AbsListView.OnScrollListener {

private int listViewTouchAction;
private static final int MAXIMUM_LIST_ITEMS_VIEWABLE = 99;

public NestedListView(Context context, AttributeSet attrs) {
    super(context, attrs);
    listViewTouchAction = -1;
    setOnScrollListener(this);
    setOnTouchListener(this);
}

@Override
public void onScroll(AbsListView view, int firstVisibleItem,
                     int visibleItemCount, int totalItemCount) {
    if (getAdapter() != null && getAdapter().getCount() > MAXIMUM_LIST_ITEMS_VIEWABLE) {
        if (listViewTouchAction == MotionEvent.ACTION_MOVE) {
            scrollBy(0, -1);
        }
    }
}

@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}

@SuppressLint("DrawAllocation")
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);

    int newHeight = 0;
    final int heightMode = MeasureSpec.getMode(heightMeasureSpec);
    int heightSize = MeasureSpec.getSize(heightMeasureSpec);
    if (heightMode != MeasureSpec.EXACTLY) {
        ListAdapter listAdapter = getAdapter();
        if (listAdapter != null && !listAdapter.isEmpty()) {
            int listPosition;
            for (listPosition = 0; listPosition < listAdapter.getCount()
                    && listPosition < MAXIMUM_LIST_ITEMS_VIEWABLE; listPosition++) {
                View listItem = listAdapter.getView(listPosition, null, this);
                //now it will not throw a NPE if listItem is a ViewGroup instance
                if (listItem instanceof ViewGroup) {
                    listItem.setLayoutParams(new LayoutParams(
                            LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
                }
                listItem.measure(widthMeasureSpec, heightMeasureSpec);
                newHeight += listItem.getMeasuredHeight();
            }
            newHeight += getDividerHeight() * listPosition;
        }
        if ((heightMode == View.MeasureSpec.AT_MOST) && (newHeight > heightSize)) {
            if (newHeight > heightSize) {
                newHeight = heightSize;
            }
        }
    } else {
        newHeight = getMeasuredHeight();
    }
    setMeasuredDimension(getMeasuredWidth(), newHeight);
}

@Override
public boolean onTouch(View v, MotionEvent event) {
    if (getAdapter() != null && getAdapter().getCount() > MAXIMUM_LIST_ITEMS_VIEWABLE) {
        if (listViewTouchAction == MotionEvent.ACTION_MOVE) {
            scrollBy(0, 1);
        }
    }
    return false;
}

This line is indicated in the log: View listItem = listAdapter.getView(listPosition, null, this); (line 53)

I'm doing this way because, in my opinion, the app would look more beautiful if there is a "Yesterday" instead of "Thu, 12 May 2016 15:43:00 +0200"; or "2 days ago", ... and so on.

    CustomList.context = context;
    this.web = web;

Answer 1

What is the returned type of getPubdate() method? Is it long or String?

Check if it's not a null and is long.

Update:

Since the returned date from web.get(position).getPubdate() is in a String format, you have to parse it to a Date object via SimpleDateFormat, ie:

SimpleDateFormat sdf = new SimpleDateFormat("EEE, dd MMM yyyy h:mm:ss Z");
Date date = sdf.parse(web.get(position).getPubdate());

Answer 2

You are calling the new Date(String s) constructor. Quoting javadoc:

Deprecated. As of JDK version 1.1 , replaced by DateFormat.parse(String s) .

Allocates a Date object and initializes it so that it represents the date and time indicated by the string s , which is interpreted as if by the parse(java.lang.String) method.

You are using a method that have been deprecated since 1997 . Deprecated means "that programmers are discouraged from using it, typically because it is dangerous, or because a better alternative exists ".

The error message says that getPubdate() returned the string Mon, 09 May . This definitely not a value that any Java parser can handle without an explicit format string. This includes the new Date(String s) call that you shouldn't be using anyway.

What kind of date value is that even supposed to be? There is no year!

Answer 3

Looking at the top of the stacktrace it looks like an incomplete string is being passed to the Date constructor, ie, there is no year and it's possibly illformed.

Try capturing what web.get(position).getPubdate() returns before calling the Date constructor.
