The real answer is to use:

<code>Color.parseColor(myPassedColor)</code> in Android, <code>myPassedColor</code> being the <code>hex</code> value like <code>#000</code> or <code>#000000</code> or <code>#00000000</code>.

However, this function <a href="http://developer.android.com/reference/android/graphics/Color.html#parseColor(java.lang.String)" rel="noreferrer">does not support shorthand hex values</a> such as <code>#000</code>.

blocks|key|604311|text|我也有同样的问题，我在#AAAAAA的表单中发现了一些颜色，我想把它转换成一个安卓可以利用的表单。我发现你可以直接使用0xFFAAAAAA，这样安卓就可以自动辨别颜色了。注意，第一个FF告诉我们alpha的值。希望能有所帮助|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|604312|entityMap^0|B|7|1N|A|2J|2|2P|5|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|G|$]]

I have the same problem that I found some color in form of <code>#AAAAAA</code> and I want to conver that into a form that android could make use of. 
I found that you can just use <code>0xFFAAAAAA</code> so that android could automatically tell the color. Notice the first <code>FF</code> is telling <code>alpha</code> value. 
Hope it helps

blocks|key|604402|text|我也面临着同样的问题。这样我就能解决这个问题了。正如CQM所说，使用Color.parseColor()可以很好地解决这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|604403|下面是我使用的代码：|604404|this.Button_C.setTextColor(Color.parseColor(prefs.getString("color_prefs",+String.valueOf(R.color.green))));|code-block|syntax|javascript|604405|在本例中，我的目标是当我从首选项(color_prefs)中更改颜色选择时，更改按钮的文本颜色(Button_C)。|604406|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

I was facing the same problem. This way I was able to solved it. 
As CQM said, using Color.parseColor() is a good solution to this issue.

Here is the code I used:

<pre><code>this.Button_C.setTextColor(Color.parseColor(prefs.getString("color_prefs", String.valueOf(R.color.green))));
</code></pre>

In this case my target was to change the Button's text color (Button_C) when I change the color selection from my Preferences (color_prefs).

if you can pass the values as static const, you can convert the hex value to an Android (android.graphics.Color) using this online converter and put the color reference in the const, ie: color converter give me this value for this color #EE5670 = 0xFFEE5670.

Try this, create drawable in your resource...

 &lt;solid android:color="@color/white"/&gt;
 &lt;size android:height="20dp"

then use...

<pre><code> Drawable mDrawable = getActivity().getResources().getDrawable(R.drawable.bg_rectangle_multicolor);
mDrawable.setColorFilter(Color.parseColor(color), PorterDuff.Mode.SRC_IN);
mView1.setBackground(mDrawable);

with color... "#FFFFFF"

if the color is transparent use... setAlpha

<code>mView1.setAlpha(x);</code> with x float 0-1 Ej (0.9f)

I am receiving hex color values from a server (in this form, <code>#xxxxxx</code> , example <code>#000000</code> for black)

How do I convert this to an integer value? 

I tried doing <code>Integer.valueOf("0x" + passedColor.substring(1, passedColor.length()))</code> to get an even more hextastic <code>0x000000</code> result, but this isn't intepreted as an <code>int</code> here, any other suggestions?

I receive an error: <code>08-03 21:06:24.673: ERROR/AndroidRuntime(20231): java.lang.NumberFormatException: unable to parse '0x00C8FBFE' as integer</code>

I am using the Android SDK for their <code>setBackgroundColor(int color)</code> function, which takes - as you might have guessed - an integer color value.

This is the OPPOSITE of this question: <a href="https://stackoverflow.com/questions/6539879/how-to-convert-a-color-integer-to-a-hex-string-in-android">How to convert a color integer to a hex String in Android?</a>

我正在从服务器接收十六进制颜色值(在此表单中，#xxxxxx，例如黑色的#000000 )如何将其转换为整数值？我试着做Integer.valueOf("0x" + passedColor.substring(1, passedColor.length()))来得到一个更加十六进制的0x000000结果，但是这里没有解释成int，还有其他的建议吗？我收到一个错误：08-03 21:06:24.67
