blocks|key|3479764|text|看看this+answer吧。你可以在Android+github镜像上浏览platform+colors和styles。请注意，对于不同的Android版本，此值可能不同。如果你想使用平台风格，只是不要为控件创建你自己的自定义选择器。希望这能有所帮助。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3479765|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/9947364/1000551|1|https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/colors.xml|2|https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/styles.xml^0|2|B|0|1B|6|1|1I|6|2|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]|$A|T|B|U|1|V]|$A|W|B|X|1|Y]]|C|$]]|$1|D|3|-4|5|6|7|Z|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]|N|$5|G|H|I|C|$J|O]]]]

Take a look at <a href="https://stackoverflow.com/a/9947364/1000551">this answer</a>. You can browse through the platform <a href="https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/colors.xml" rel="nofollow noreferrer">colors</a> and <a href="https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/styles.xml" rel="nofollow noreferrer">styles</a> at the Android github mirror. Please note this values can be different for every version of Android. If you want to use platform styles, just don't create your own custom selectors for the controls. Hope it will help.

blocks|key|444386|text|你可以像Jignesh解释的那样得到list_selector_background可绘制的，然后找到它的平均颜色，如所示(我会在你的初始化代码中这样做，这样你就不必每次都浪费时间处理它们，但是嘿，这还为时过早)。这应该与主题足够一致，以便让您的小部件根据需要进行匹配。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|BOLD|entityRanges|data|444387|您的代码可能如下所示：|444388|public+static+Color+getPlatformSelectionColor(Context+c)+{

You could just get the <code>list_selector_background</code> drawable, as explained by Jignesh, and then find its average color as shown in <a href="https://stackoverflow.com/a/12408627/832776">this answer</a> (I'd do it in your initialization code so you don't have to waste processing them every time, but hey, that's premature optimization). That should be consistent enough with the theme to let your widgets match as needed.

Your code could look like this:

<pre><code>public static Color getPlatformSelectionColor(Context c) {
 Bitmap bitmap = BitmapFactory.decodeResource(c.getResources(),
 android.R.drawable.list_selector_background);
 long redBucket = 0;
 long greenBucket = 0;
 long blueBucket = 0;
 long pixelCount = 0;

 for (int y = 0; y &lt; bitmap.getHeight(); y++)
 {
 for (int x = 0; x &lt; bitmap.getWidth(); x++)
 {
 Color c = bitmap.getPixel(x, y);

 pixelCount++;
 redBucket += Color.red(c);
 greenBucket += Color.green(c);
 blueBucket += Color.blue(c);
 // does alpha matter?
 }
 }

 Color averageColor = Color.rgb(redBucket / pixelCount,
 greenBucket / pixelCount,
 blueBucket / pixelCount);
 return averageColor;
}
</code></pre>

blocks|key|5591651|text|你可以在谷歌自己的设备上轻松实现这一点，但对于其他制造商来说就不是了，因为大多数制造商已经覆盖了几乎所有android版本的默认颜色、布局、背景等，包括果冻豆。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5591652|因此，理想情况下，它不被推荐，也很难遵循每个人的设计指南。|5591653|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

You can achieve easily achieve this for google owned devices but not for other manufacturers as most of the manufacturers have overridden the default colors, layouts, backgrounds, etc for almost all the versions of android including jelly-beans.

So ideally its not recommended and also tough to follow each and everyone's design guidelines.

I need to get the selection color used by Android to draw ListView and EditText selection. I know these controls user selectors to draw their states, but I've written a few widgets that I want to match the selection color of the platform they are running on and the drawables that are defined can't do that because they are using 9 patch images instead of colors.

I've looked all through the Android source and haven't found a color selector or color constant I can use to get the color I'm looking for.

How do you get the selection color in Android?

我需要得到的选择颜色由安卓用来绘制ListView和EditText选择。我知道这些控件是用用户选择器来绘制它们的状态的，但我已经写了一些小部件，我想要匹配它们运行的平台的选择颜色，而定义的绘图无法做到这一点，因为它们使用9个补丁图像而不是颜色。我已经看遍了Android的所有源代码，但还没有找到可以用来获得我正在寻找的颜色的颜色选择器或颜色常量。
