Android/Java: onProgressUpdate() not being called?
提问by qwerty
I've read similar threads on here, even googled but no solution.
我在这里读过类似的帖子,甚至用谷歌搜索过但没有解决方案。
onProgressUpdate() is just not being called.
onProgressUpdate() 只是没有被调用。
Here's the code:
这是代码:
public class DoHardWork extends AsyncTask {
@Override
protected Object doInBackground(Object... params) {
publishProgress("Requesting XML data");
this.requestData();
publishProgress("Returning results");
this.returnResults();
return null;
}
protected void onProgressUpdate(String text) {
super.onProgressUpdate(text);
MainActivity.setLog(text);
}
}
I tried setting a breakpoint in onProgressUpdate() and it's never called. It's like the code is just ignored.
我尝试在 onProgressUpdate() 中设置断点,但从未调用过。就像代码被忽略了一样。
Someone had a similar problem and it turned out to be just eclipse just messing with him but i tried restarting it with no success.
有人遇到了类似的问题,结果只是 eclipse 惹恼了他,但我尝试重新启动它但没有成功。
Any ideas?
有任何想法吗?

I think that you missed somethings on your code. Try with this one:
我认为您错过了代码中的某些内容。试试这个:
private class DoHardWork extends AsyncTask<Void, String, Long> {
protected Long doInBackground(Void... urls) {
publishProgress("Requesting XML data");
this.requestData();
publishProgress("Returning results");
this.returnResults();
return null;
}
protected void onProgressUpdate(String... progress) {
super.onProgressUpdate(progress);
MainActivity.setLog(progress[0]);
}
}
