Question

I have an activity whose only purpose is to launch an AlertDialog. My issue is that I cannot figure out what to have the activity extend so that the dialog opens on top of whatever the user has open. Currently, it opens a blank layout behind it with extends Activity. Everything else I try fills the activity with errors. Do any of you wonderful internet people know what I can do to make it so that only the alertDialog opens when the activity is triggered?

Try adding an own style. Create (if you don’t yet have it) a file styles.xml in res\values\, and add this:

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="Dialog.NoTitleBar" parent="@android:style/Theme.Dialog">
        <item name="android:windowNoTitle">true</item>
    </style>
</resources>

Then, in your AndroidManifest.xml, set this style as the android:theme:

<activity
        android:name="MyActivity"
        android:theme="@style/Dialog.NoTitleBar" />
