Answer 1

Use Activity Context

     final Dialog dialog= new Dialog(ActivityName.this);

To know when to use activity context

When to call activity context OR application context?

From the comments

How to set dialog to show with full screen?

Edit:

From Dianne Hackborn suggestion

Give its constructor a non-dialog theme, such as android.R.style.Theme or android.R.style.Theme_Light.

Look @ the themes

https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/themes.xml.

More info @

https://groups.google.com/forum/#!topic/android-developers/NDFo9pF8sHY

   Dialog dialog=new Dialog(ActivityName.this,android.R.style.Theme);

Answer 2

Use

final Dialog dialog= new Dialog(getApplicationcontext()); OR  final Dialog dialog= new Dialog(YOUR_ACTIVITY.this);

instead of

final Dialog dialog= new Dialog(getBaseContext());

Answer 3

try this

final Dialog dialog= new Dialog(YOUR_ACTIVITY.this);

instead of

final Dialog dialog= new Dialog(getBaseContext());
