I am writing an Android application at the moment, no knowledge of java what so ever, except what I have learnt in the last 5 hours. I’ve managed to implement a two screens and a nice looking layout.
I have three questions:
- How do I set the Action Bar on Honeycomb to be transparent like in the Google Maps application? I want to be able to partially see the background graphic through it.
- What code to use to empty five edit texts and a textview on button click? I’ve read something about a viewgroup, but I have no idea how to implement that…
- I have a linearlayout with a tablelayout centred horizontally and vertically inside it, and eleven table rows in that. How do I set a partially transparent black as a sort of fill colour for the tablelayout without ruining the background of the linearlayout? Every time I try to set a fill colour it blacks out the entire background image of the layout surrounding it as well.
Plain english would be preferable because I am so new to this.
Thanks heaps for any replys, have a great day.
Answer to your 1st question: You can implement a theme on the HoneyComb action bar. Check this link for more info. The color would be something like this: #29000000.
The first hex 2-digit(#29) represents alpha channels of color and set opacity. If value is “00” that means 100% transparent. if value is set it will be opaque, it can be any value in 00 to FF.
