Question

My code:

Style:

<style name="theme_sms_receive_dialog" parent="android:style/Theme.Dialog">     <item name="android:windowNoTitle">true</item>     <item name="android:background">@android:color/transparent</item>     <item name="android:windowBackground">@android:color/transparent</item>     <item name="numberPickerStyle">@style/NPWidget.Holo.Light.NumberPicker</item> </style>

You need to get the current Window and set it's LayoutParams like so:

Dialog d=new Dialog(mContext); ......... ......... myDialog.show(); Window window = myDialog.getWindow(); window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT); 

Alternative(if above solution does't works)

In case above code not works well you can use a workaround

styles.xml

<style name="mydialog"></style> 

Java

Dialog d=new Dialog(mContext,R.style.mydialog); ......... ......... myDialog.show(); Window window = myDialog.getWindow(); window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
