Menu
I'm writing an Android application and I would like to place a dialog or view over the home screen so that a user can enter text without jumping into my full application. I can't seem to get this to work. If I present a dialog (even in a transparent activity), my application launches.
If you don't know what I'm talking about, take a look at the Facebook widget. I want to replicate a similar behavior to the clicking on the "What's on your mind?" box.
Thanks for any help in advance!

Showing the DialogFragment It is not necessary to manually create a FragmentTransaction to display your DialogFragment . Instead, use the show() method to display your dialog. You can pass a reference to a FragmentManager and a String to use as a FragmentTransaction tag.
Displaying the dialog-as-an-Activity will cause the new Activity to be on the top of the stack, pausing what previously was there. There are two more such scenarios when onPause() will get called.
A dialog is a small window that prompts the user to make a decision or enter additional information. A dialog does not fill the screen and is normally used for modal events that require users to take an action before they can proceed. Dialog Design.
You can override activity method onWindowFocusChanged(boolean hasFocus) and track the state of your activity. Normally, if some alert dialog is shown above your activity, the activity does not get onPause() and onResume() events.
My problem was that the application always launched to display the dialog.
To solve this, I set the activity lauch mode to singleInstance in the manifest. Now it shows the dialog over the home screen!
