Hi
I've got an app that spawns of a seperate thread. Parses JSON data into a
structure. And passes it back to the main thread through a handler. Each
part of data is sent through the handler individually. That worked fairly
well with my previous XML parser, as XML parses data while it downloads. But
JSON doesn't (atleast I haven't found a way to get that working). In either
way the JSON data is much smaller and much faster to parse.
I've recently added a feature that requires me to load several sources of
json in parallel, parse in the background, and pass all the data back again
using a Handler. This is a bit slower than I was hoping.
Would it be faster (and possible) for me to do this:
BackgroundThread extends Thread {
onCreate (Parent) {
this.parent = parent;
}
onData {
parent.addParsedData(x);
}
}
Parent extends ListActivity {
ListAdapter list;
onCreate {
setListAdapter(list);
new BackgroundThread(this);
}
public synchronized addParsedData(data) {
list.add(data)
}
}
I'm thinking this won't be thread safe, as ListAdapter is in the parent
thread. Am I right?
Should I instead inside the listadapter (which puts data in an array) have
synchronized access to it's items?
