Answer 1

try to add style on your res/values/styles.xml

    <resources xmlns:android="http://schemas.android.com/apk/res/android">
       <style name="AlertDialogCustom" parent="@android:style/Theme.Holo.Light.Panel">
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:backgroundDimEnabled">true</item>
       </style>
    </resources>

and apply these style to your dialog like below code:

 final Dialog dialog = new Dialog(HomePage.this, R.style.AlertDialogCustom);
 dialog.setContentView(R.layout.popupaddcustomer);
 dialog.show();

Answer 2

Try to call in your dialog constructor:

getWindow().setBackgroundDrawableResource(android.R.color.transparent);
