FirstPageActivity
SecondPageActivity

The App call the SecondPageActivity by the FirstPageActivity... and the App send HttpRequest In the SecondPageActivity.

So I want to show Progress Dialog in the FirstPageActivity and After the SecondPageActivity Finish downloading the data, it Dismiss the Progress and then Appear.Is that Possible ?

Actually The Customer doesn't want to show the progress in the second Activity Because it will be empty for a while, and that not so good :( – Abroach 4/5, 2014 at 15:56

No.

You can't handle one Activity's UI functionality or any functionality from another `Activity.

If you start a ProggressDailog in FirstPageActivity then you must be dismiss it in onPause() before proceeding to other Activity as you said SecondPageActivity.

You can start a new ProggressDailog in SecondPageActivity from onCreate() or onResume() method.

Update: From the document of ProggressDailog you can see, to initialize a ProggressDialog its need to pass the current Activity context.

ProgressDialog(Context context)
ProgressDialog(Context context, int theme)

So if I want to do that, I should Download the data in the FirstPageActivity and then send it to SecondPageActivity... – Abroach 4/5, 2014 at 15:52

Yeah, that will be a good way. Can I know what is the purpose of SecondPageActivity? If say the purpose then I can help you in more specific way. – Aggiornamento 4/5, 2014 at 15:55

yes, it will show the downloaded data from the http request, Actually I want to show the progress in the firstActivity because I don't want to show the progress bar on an empty activity until it finish download the data – Abroach 4/5, 2014 at 16:0

are you downloading data in FirstPageActivity or in SecondPageActivity? – Aggiornamento 4/5, 2014 at 16:7

I will explain my problem again : I want the behind view of the progress dialog to be the firstPageActivity, and when the second Activity ready to appear "that mean that has been downloaded the data" so I will dismiss the progress and show the second Activity. now I think this impossible if I download the data in the second Activity , and the only solution is to downloaded in the first Activity !!!! that's right ??? – Abroach 4/5, 2014 at 16:14

and the App send HttpRequest In the SecondPageActivity.

As you say SecondPageActivity send HttpRequest , then best way is to show the ProgressDialog in SecondPageActivity.

In onCreate of SecondPageActivity show the ProgressDialog and dismiss it when HttpRequest complete

Yes I agree with you,but Actually the Customer want to show the progress in the firstPageActivity, Instead of showing progress in the SecondActivity, because SecondActivity will be empty for a while :( – Abroach 4/5, 2014 at 15:55

You can still show the ProgressDialog in FirstActivity and dismiss it after SecondPageActivity is started – Cubism 4/5, 2014 at 15:57

yes but then the second activity will be empty for a while, until it download the data ,,, yes ? – Abroach 4/5, 2014 at 16:1

No. As I said show the dialog in onCreate of secondActivity – Cubism 4/5, 2014 at 16:3

ok, but then the first activity will be disappeared and the background of the progress will be an empty activity because the data didn't download !!!! – Abroach 4/5, 2014 at 16:10

You said the secondActivity is the one downloading the data, so I believe it will start download only after it is invoked by FirstActivity. When you start the Activity, immediately it will be on top of the stack – Cubism 4/5, 2014 at 16:15

Yes, an Activity should be in Foreground to start a download request. It is better to do it in FirstActivity and then start the SecondActivity. – Cubism 4/5, 2014 at 16:42
