android - Setting list item background color loses highlighting -


I have created an inbox activity and I am mirroring some of the default mail applications that come with Android.

In the mail, the background color of a message that has not been read is a slight color compared to the rest of the list. I have reflected it by calling the setBackgroundResource in my adapter's getView method, SetBackgroundColor does nothing. 

  if (! MsgSum.getIsRead ()) {LinearLayout l = (LinearLayout) v.findViewById (R.id.inbox_background); If (l! = Null) {l.setBackgroundResource (R.color.inbox_unread); }} And {LinearLayout l = (LinearLayout) v.findViewById (R.id.inbox_background); If (L! = Null) {l.setBackgroundResource (R.color.inbox_read); }}

The problem is, the items lose the ability to highlight again. What do I mean, usually if you scroll your mouse wheel with the emulator (or if you have some scrolling capabilities in your Android device), the list item will be as yellow as they focus.

Thank you for your help

The reason is that the list item Highlight is created behind you need to prepare a state list for the background of your item which sets the background color transparent in the selected state. If you talk about the list of inventory listed on Google I / O 2010 If so, you'll get an example of how to do this.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
