网友答案:

Works better with noTitleBar to create a full transparent activity

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

and remember extends your activity from Activity and not from AppCompactActivity

If you need to use AppCompact then declare a new theme:

<style name="Theme.AppCompat.Translucent" parent="Theme.AppCompat.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:colorBackgroundCacheHint">@null</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowAnimationStyle">@android:style/Animation</item>
</style>
