Question

I’m making an Android application and it has to load some data though Internet (only some data– not all). So when the data is loading, and the Internet connection is slow, I want to show a “Loading…” icon to the user.

So how can I do this? Show a “Loading…” icon while the data is being loaded in the background, and when its completely loaded, hide the icon?

Thanks in advance!

use Async Task for your status.

new SomeTask(0).execute();

/** Inner class for implementing progress bar before fetching data **/
private class SomeTask extends AsyncTask<Void, Void, Integer> 
{
    private ProgressDialog Dialog = new ProgressDialog(yourActivityClass.this);

    @Override
    protected void onPreExecute()
    {
        Dialog.setMessage("Doing something...");
        Dialog.show();
    }

    @Override
    protected Integer doInBackground(Void... params) 
    {
        //Task for doing something 

        return 0;
    }

    @Override
    protected void onPostExecute(Integer result)
    {

        if(result==0)
        {
             //do some thing
        }
        // after completed finished the progressbar
        Dialog.dismiss();
    }
}
