title: DialogFragment in Android with theme
body: <p>I'm building my first app in android. I've made a dialogFragment, but it doesn't look nice enough.For having a style and a theme I used this <code>setStyle(DialogFragment.STYLE_NORMAL,0)</code>. What I want is that the edge of the fragment to be black like a frame, or have its corners round. I think I must write my own style in xml and put it in styles, but I'm not sure. Can someone point me to the right direction? Thank you for your time.</p>
