I have an Activity named whereActity which has child dialogs as well. Now, I want to display this activity as a dialog for another activity.
How can I do that?

Alert Dialog shows the Alert message and gives the answer in the form of yes or no. Alert Dialog displays the message to warn you and then according to your response the next step is processed. Android Alert Dialog is built with the use of three fields: Title, Message area, Action Button.
Dialog has an isShowing() method that should return if the dialog is currently visible. So you can use that to see if a dialog is showing and hide it with dismissDialog(). You just have to keep a reference to the Dialogs you create in onCreateDialog().
when a dialog is shown or it's window comes visible on top of an existing activity, then it overrides partial the activity window so existing activity will move to partially invisible state and you will get call to onPause() from ActivityThread. but to be sure we also need to consider here a one think...
To start activity as dialog I defined it like this in AndroidManifest.xml:
<activity android:theme="@android:style/Theme.Dialog" /> Use this property inside your activity tag to avoid that your Dialog appears in the recently used apps list
android:excludeFromRecents="true" If you want to stop your dialog / activity from being destroyed when the user clicks outside of the dialog:
After setContentView() in your Activity use:
this.setFinishOnTouchOutside(false);
Now when I call startActivity() it displays as a dialog, with the previous activity shown when the user presses the back button.
Note that if you are using ActionBarActivity (or AppCompat theme), you'll need to use @style/Theme.AppCompat.Dialog instead.

Use this code so that the dialog activity won't be closed when the user touches outside the dialog box:
this.setFinishOnTouchOutside(false); requires API level 11
