How can i make the background 50% transparent?
Let's say the background of an AbsoluteLayout so it's dark but you can still see through it?

You could apply a transparent theme to the required activity. Create a new style in /res/values/style.xml
您可以将透明主题应用于所需的活动。在 /res/values/style.xml 中创建新样式
<resources>
<style name="Transparent">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowAnimationStyle">@android:style/Animation.Translucent</item>
<item name ="android:windowBackground">@color/transparent</item>
<item name="android:windowNoTitle">true</item>
<item name="android:colorForeground">#fff</item>
</style>
</resources>
The value of transparent is

<color name="transparent">#00000000</color>
Now in AndroidManifest.xml declare the theme of the activity to the one you just created.
现在在 AndroidManifest.xml 中将活动的主题声明为您刚刚创建的主题。
<activity android:name="MyActivity" android:theme="@style/Transparent"></activity>
