Android Borderless Dialog

Question

I have created an AlertDialog using AlertDialog.Builder, but the Dialog border takes up too much space on the screen. How do I remove the border? I have tried using another

Answer 1

Using android.R.style.Theme_Translucent_NoTitleBar works if you want the dialog to be full screen. An alternative is to create your own style, like so:

<style
    name="Theme_Dialog_Translucent"
    parent="android:Theme.Dialog">
    <item
        name="android:windowBackground">@null</item>
</style>

Answer 2

if you have 2 border you need to use a ContextThemeWrapper, which it will show only one border as you would like :)

ContextThemeWrapper wrapper = new ContextThemeWrapper(this, android.R.style.Theme_Holo);
final LayoutInflater inflater = (LayoutInflater) wrapper.getSystemService(LAYOUT_INFLATER_SERVICE);
AlertDialog.Builder builder = new AlertDialog.Builder(wrapper);
