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.

dialog.setContentView(R.layout.Yourlayout);

create an layout as you like to have as a dialogue and create an activity using that layout.
in the manifest declare that activity and add android:theme="#android:style/Theme.Dialog in that activity stub.

How To Get A Pop Up Layout?

How can I have a pop-up window, with a new layout, but with the old layout in the background?
Also I'd like to have a button on the first layout call the second layout based on an if-statement, using something like this
"if Button has a background, button open new layout, if not null"

You could use a Dialog to create the pop-up. For example, in your activity onCreate() method set up a new dialog and specify the layout using XML like normal.
Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.--);
then simply call dialog.show() when you want to show the pop-up.
