Android transparent image in popup is not transparent

I am trying to display a transparent image as a popup. To do this, I customized popupwindow to suit my needs and fanned the relative layout in that popupwindow initview ().

In this relative layout, I added a transparent image, but when I started the application, it is an oval image inside a rectangular block, so instead of transparency I could see a gray color around this oval image.

I have no option except popupwindow, because I have to use the controls on the background screen.

I tried to set a transparent style for this relative layout, although it doesn't work.

Can anyone tell me how to do this

or

There is an error in the android popup.

Thanks in advance.

We found a solution for this - when setting up the popup, we must set the background to null. setBackgroundDrawable (zero); Then it worked.

Use android themes in your popup. If this action declares it in the manifest.

Android: theme = "@ android: style /Theme.Translucent"

EDIT Set the theme for the dialog box.

mDialogTax = new dialog (mContext, android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);

There is a right solution. The problem is that against the background, popupWindow is defined in the style of the action theme.

Decision:

  • specify your theme for the application or activity displaying PopupWindow.

    • You can choose a different parent theme.

    • configure the entry "android: popupWindowStyle"

      <style name="CustomTheme" parent="@android:style/Theme.NoTitleBar">
    <item name="android:popupWindowStyle">@style/PopupWindow</item> 
</style>

  • define popupWindowStyle. entry "android: popupBacground" define the background for all pop-ups with the specified theme.

    <style name="PopupWindow" parent="@android:style/Widget.PopupWindow">
     <item name="android:popupBackground">@color/transparent</item> 
</style>

  • add CustomTheme theme to action or application

    <application
        ...
        android:theme="@style/CustomTheme" >

A popup will appear with a transparent background.
