Hi!
I have a problem. I am developing an app where I get some message
(html text) and display it in TextView. Comunication is based on JADE
and JADE-Android, but problem is not here. I can send and recieve
messages OK.
I need my TextView to disapear after some time (let say 10s) if there
is no new messages recieved. I tried Thread.sleep() but that stops the
whole thing and I don't want that. I also tried Handler.postDelayed()
and it works to some extent. Problem is, it hides TextView in any
case, even if new message is recieved before 10s is over. I need it to
hide only if there is no new message. How can I accomplish this?
Thanks for any help!
Here is the part of the code that is relevant.
In my main Activity, I create method updateText(String) -
public void updateText(String text) {
t = (TextView) findViewById(R.id.textView1);
t.setVisibility(0);
t.setText(Html.fromHtml(text));
// textViewHandler.removeCallbacksAndMessages(textViewHandler);
textViewHandler.postDelayed(new Runnable() {
public void run() {
t.setText("Handler");
t.setVisibility(4);
}
}, 10000);
}
In another class I call this method, when new message is recieved -
public void onMessageReceived(ACLMessage msg) {
// TODO Auto-generated method stub
MyUpdater up = new MyUpdater(act, msg);
handl.post(up);
}
private class MyUpdater implements Runnable {
ACLMessage msg;
CaptureActivity act;
public MyUpdater(CaptureActivity sm, ACLMessage msg) {
this.msg = msg;
this.act = sm;
}
public void run() {
act.updateText("<b>**Sporočilo agenta "
+ msg.getSender().getLocalName() +
":**</b><br/><br/>"
+ msg.getContent());
}
}
