translucency

I wish to have a transluscent background for an activity, so that the previous activity can be seen beneath this activity. Something like a transluscent menu that pops up over a videa being played in the background. Is this possible? Can you tell me how? Note:I cannot use the default transluscent theme from android, since I am using my own customised background and theme for my application. Pls help. Below is my style.xml wherein my_btn and my_list are selectors : <?xml version="1.0" encoding="utf-8"?> <resources> <style name="btnstyle" parent="@android:style/Widget.Button"> <item name=

I'm not sure if this is possible, but is there a way to safely allow popups to be translucent even when the parent container is also translucent? If not, what would be wise alternative to use or extend instead of JPopupMenu ? Note: Translucent refers to a component not 'having a background', similar to the effect of setOpaque(false); . Thanks. From a forum answer by user camickr in 2009: I don't know if transparency painting has changed in 1.6.0_10. Prior to that I believe transparency can only be achieved in lightweight components (ie. Swing does all the painting). JFrame, JWindow and JDialog

Ok, I am not that versed in Java / Swing, and I am running into a problem. My application is throwing this error: "Exception in thread "AWT-EventQueue-0" java.awt.IllegalComponentStateException: The frame is displayable." Google isn't turning up much information on this error, and a quick search of StackOverflow is not showing anything yet. What I am trying to do: just implement translucent windows using the code from the tutorials. That's it. I plan to use this as a general window for displaying notifications, such as "This program has not been run in 30 days" down near the system tray. Are

Here's the example . If you build and run TranslucentWindow in let's say, NetBeans IDE 7.0, which supports jdk7, you'll get the following exception: Exception in thread "AWT-EventQueue-0" java.awt.IllegalComponentStateException: The frame is decorated at java.awt.Frame.setOpacity(Frame.java:960) at main.TranslucentWindow.<init>(TranslucentWindow.java:23) at main.TranslucentWindow$1.run(TranslucentWindow.java:47) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:251) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:705) at java.awt.EventQueue.access$000(EventQueue.java:101

I want the UINavigationBar in my app to be completely transparent and flush with the viewcontroller directly under it. However, the only code I could find makes it translucent but not transparent. I know this can be done in iOS 7 because it is used in the notes app. My question is, what is the code they used to do it?
