无法为 Popup Window Activity 设置透明背景

Question

I am following this particular example to create a popup window activity but when I click on a button to open this activity, the background is not semi-transparent as mentioned in the example. I am new to android kotlin development so I am not able to figure this out on my own. Let me know what I am doing wrong.

EDIT: This link tells a different method but working fine.

Answer 1

You can customize the translucent theme of your activity, in your "AndroidManifest.xml" file.

<activity
        android:name=".ui.PopUpWindow"
        android:theme="@style/AppTheme_translucent" />

and in your "styles.xml" file.

<style name="AppTheme_translucent" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowTranslucentNavigation">true</item>
    <item name="android:windowBackground">@color/transparent</item>
    <item name="android:windowIsTranslucent">true</item>
</style>

Answer 2

I travel the code and did not see setContentView() method for PopupWindow activity. Please set content view for the activity by calling the method inside PopupWindow's onCreate()
