问题 I followed the android developer link to install sample package. However, when I expand the package list of Android platform, there is no " Sample for SDK " option (checkbox) available. Why?? I have installed Android from version 2.3.3(API10) to 4.0.3(API 15), none of them contain the option for downloading sample package. Why? Anyone has the same problem? 回答1: //you need to download it there is an option for that. if it show already installed you need to go to the folder called <sdk>/samples

问题 What I'm trying to do will work better with an example image. As you can see below I have a grey background, ontop of that sits a container with some padding containing an image. The container also has a slight dropshadow to it. What I want to know, is if there's so non-painstaking way of doing this in my layout.xml? In a normal HTML document this would've been easy. But since this is for a mobile app and for a number of screen resolutions and so on, it's proving a bit difficult. Any advice?

问题 I followed Android recommendation and set style="?android:attr/buttonBarStyle" to parent layout and style="?android:attr/buttonBarButtonStyle" to buttons.

From looking around, I can't seem to see anything wrong with the xml itself and I can't see what I am doing wrong. I have tried the suggestion to the problem, that is adding a weight to each of the different elements but this still hasnt solved the problem. I have

问题 I'm creating an app that creates buttons through code when an activity starts (the number of buttons depends on the number of values in an array). The colour of each individual button is defined by a corresponding value in an array, the button colour is set when I create the button. Buttons have no text and, due to setting the background colour directly, are not 9 patch images (the colour of the button has to be as close as possible to the value given). The problem that I have is that my
