Hello Mystique,
When this code starts the thread, it then goes straight back to
execute DoSomeTask() while the thread is running, and so most of the
time the dialog will be shown after DoSomeTask.
Maybe you meant to do something like this:
ProgressDialog dialog;
final Runnable runInUIThread = new Runnable() {
public void run() {
dialog.dismiss();
}
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog = new ProgressDialog(CloseVault.this);
dialog.setMessage("Please wait...");
dialog.show();
Thread myTask = new Thread() {
@Override
public void run() {
DoSomeTask();
handler.post(closeLoadingDialog);
}
};
myTask.start();
}
You are right, though, ASyncTask is a nicer way of doing it.
