Handler and Progress

[Pratik Goswami]

Hello Friends,

I am having trouble with Progress Dialog and Handler. The scenario is something like this - I have am having one function that set Handler to call after 2 seconds (postDelayed). I need to start Progress dialog when handler start to perform runnable function. I am able to display Progress Dialog but it is not animating all.

Any help guise?

Thanks

Maybe your code is still running on the main thread and therefore the Animation is not not smooth. Can you post some code? That way people will have better view of your problem.

Thanks Monu,

Here is the code snippet -

    
btnSelectViewItemPrev = (ViewImgButton) findViewById(R.id.btnSelectViewItemPrev);
btnSelectViewItemPrev.SetButtonIcon(R.drawable.btnprev, -1);
btnSelectViewItemPrev.setOnClickListener(new View.OnClickListener() {
	public void onClick(View v) {
		CurrentAgendaView.SetPrevViewItem();
		RefreshAgendaAfterViewItemChange(0);
	}
});

public void RefreshAgendaAfterViewItemChange(int isToday) {
	btnSelectViewItemToday.setText("...");
	// filter data
	dataViewAppt.FilterData(CurrentAgendaView.GetViewStartDate(),CurrentAgendaView.GetViewType());

		// rebuild view
	if(iCurrentAgendaViewType != AgendaView.viewMode.MONTH)
		CurrentAgendaView.RebuildViewAppointments(dataViewAppt);
		
	UpdateCurrentViewItemDate();
	scrollViewAgenda.scrollTo(0, 0);		
	mHandler.removeCallbacks(startDrawing);     // Remove all previous callbacks 
	mHandler.postDelayed(startDrawing, 2000);   // Set 2 second time interval
}

public Runnable startDrawing = new Runnable() {
	@Override
	public void run() {	
		showDialog(mDialogProgress);
		startDelayedDataa.run();
	}
};

public Thread startDelayedDataa = new Thread() {
	@Override
	public void run() {
		if(iCurrentAgendaViewType == AgendaView.viewMode.MONTH)
				CurrentAgendaView.RebuildViewAppointments(dataViewAppt);			
		else {
			CurrentAgendaView.getBusinessTime();
			CurrentAgendaView.Rebuild();
		}
	dismissDialog(mDialogProgress);
	}
};

Thanks
