I'm creating an application in which I've to display a dialog box. This dialog box having an edittext and a button. I want to display this dialog box before activity starts. please help me.
Create an instance of dialog in onCreate(); and show it in onResume();
you can use a dialog fragment:

this is an example of how to use it:
check out this tutorial
there are some ways where what you can do is you can have a activity which is registered as
<activity android:theme="#android:style/Theme.Dialog" />
at manifest and show the activity before yours activity that it will be an appearance of dialog beside this

Since I read showing Alert Dialog on Service may damage on other program , I want to know is there difference between showing Alert Dialog directly like this:
AlertDialog alertDialog = builder.create();
alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
alertDialog.show();
And showing through specific activity?
I want something like communication application's popup (e.g. Line Messenger,..)
which of ways do you recommend?
You can start a Transparent activity from your service which shows the dialog within itself.
First create the "transparent" activity and set its theme like this in the Manifest
<activity android:name=".MyPopUpActivity" android:theme="#android:style/Theme.Translucent.NoTitleBar.Fullscreen"/>
Set the background of this activity to a transparent colour of your choice.
From your service, start this activity. Make sure to pass whatever data needed to show the Dialog.
Once the activity is launched, use a DialogFragment to show the dialog. Using DialogFragment is the recommended way to display dialogs in android.
I haven't tested this approach myself but I am pretty sure it will do the trick for you.
Let me know if it works for you
How to display calculator inside dialog box in android? I saw some examples but they add only view inside dialog box, but I want to add whole activity inside dialog.

I have a ListActivity act as dialog. It's fine. when i select item click show another listactivity as dialog. But i want to show second listactivity as pop up window based activity.

Already have this question in stackoverflow. I know some code are missed. what are the steps. pls help me. Advanced thanks,
Android activity can create as dialog and. activity can run single screen only. multiple activity run on fragment only. you can't make popup window as a activity.
Set below property in manifest for the activity which you want to be open as dialog:
<activity android:theme="#android:style/Theme.Dialog" />
My appliation do the following:
Start a alarm
after 10 second
open a Activity (ThemeDialog)
The output is as follows
I would like to do the following:
Just show the dialog without showing the main activity
But the current situation is that the main activity is opened when I open my dialog activity.
How to hide it (when the alarm timesup, i just want to display a dialog)? Just like the following screen shot:

You just also finish activity and than open new activity. New Activity' s style to android:theme="#style/Theme.Translucent" in your manifest file. And than set a view maybe empty textview, open dialog.
you can acheive this by using custom dialog
.in this give background color to black it will hide back activity
or you can acheive this by launching activity as dialog
Start activity as dialog i used this
<activity android:theme="#android:style/Theme.Dialog" />
now when i startActivity(in) it displays like dialog.
instead of showing dialog in activity you can directly use dialog theme in manifest file for activity.and use that activity as a dialog box.
I'm using an AlertDialog with 2 buttons (one positive, one negative).
I've set a handler for those buttons which doesn't mention dismiss. Indeed after clicking, I don't want the dialog to close. However, it seems that as soon as we click on a positive/negative button on an AlertDialog, it always get closed.
Is there a way to prevent the dialog from closing after clicking on any button ?
Thanks,
Vincent
Use custom layout for Dialog and you will be happy!
Use a custom dialog, not an AlertDialog.
You can also create a new Activity and assign it the theme dialog in your manifest with
<activity android:name="MyDialogActivity" android:theme="#android:style/Theme.Dialog" />
