Hi,
Android docs(1) suggest using threads and a handler to send messages
(to avoid ANR).
Fine. I've always done that but then porting some code to Android
noticed that it's not necessary.
Passing the Activity (i.e. Context) works fine.
public class WorkerThread extends Thread {
private Activity mActivity;
public WorkerThread(Activity mActivity) {
super();
this.mActivity = mActivity;
}
@Override
public void run() {
mActivity.showToast("WorkerThread thread says hello"); //
displays a message
//setting a TextView works fine too
...
}
I understand the potential for memory leaks (2), but if I control the
WorkerThread lifecycle (it dies when the the Activity pauses), then
really there is no need to use a handler, is there? Or do I
misunderstand?
