I have a process in a button (large process). I want to update the TextView with diferents values. Like:
- Connecting…
- Receiving Files…
- Complete…
etc..
I’m using setText(); void, but I’m getting only the last value of setText();, in that case:
estatEdit.setText(“Tareas completadas!”);
Here is my code…
public class sincroGeneral extends Activity implements OnClickListener {
private static final String CATEGORIA = "libro";

Internet connection is a blocking action, i.e. it blocks the UI until the action is complete (this is why only the last update is seen). You have to move it to a Thread (or even better to an AsyncTask). But then you get another problem, you cannot update UI from outside the main Thread. So, you have to use a Handler to update the UI.
