在资源字符串中更改单词颜色

Is there anyway to set the color of a string resource in android? I mean, I know I can use some html tags to change string style (or substrings) but have not found any to change color. I have seen other solutions here at * like passing the string to Html.fromHtml(string) before setting the text but I want to do it in the string resource editor. Any possibility?

在android中是否有设置字符串资源的颜色?我的意思是，我知道我可以使用一些html标签来改变字符串风格(或子字符串)，但是我没有发现任何可以改变颜色的标签。我在*上见过其他解决方案，比如在设置文本之前将字符串传递给Html.fromHtml(string)，但我想在字符串资源编辑器中进行。有可能吗?

As far as I know it is not possible. I would use a SpannableString to change the color.

据我所知，这是不可能的。我将使用一个SpannableString来改变颜色。

    int colorBlue = getResources().getColor(R.color.blue);
    String text = getString(R.string.text);
    SpannableString spannable = new SpannableString(text);
    // here we set the color
    spannable.setSpan(new ForegroundColorSpan(colorBlue), 0, text.length(), 0);

Spannable is really nice. You can set thinks like fontseize and stuff there and just attach it to a text view. The advantage is that you can have different colors in one view.

Spannable真的很不错。你可以设置像fontcapture之类的东西把它附加到文本视图。优点是您可以在一个视图中使用不同的颜色。

Edit: Ok, if you only want to set the Color the solution mentioned above me is the way to go.

编辑:好的，如果你只想设置颜色，我上面提到的解决方案就是最好的办法。

It looks like this method is working:

看起来这个方法是有效的:

    <string name="some_text">this is <font fgcolor="#ffff0000">red</font></string>

The strings themselves have no color, but you can change the color of the text in the textView they appear in. See the textview documentation, but there are 2 ways to do it.

字符串本身没有颜色，但是您可以在它们所显示的textView中更改文本的颜色。请参阅textview文档，但是有两种方法。

XML

android:textColor

Code

代码

setTextColor(int)

I have recently made a flexible solution for this problem. It enables me of easily add multiple styles to substrings by using method chaining. It makes use of the SpannableString. When you want to give a certain substring a color, you can use ForegroundColorSpan.

我最近针对这个问题提出了一个灵活的解决方案。通过使用方法链接，可以轻松地向子字符串添加多种样式。它利用了SpannableString。当你想要给某个子字符串一个颜色时，你可以使用前置色距。

public StyledString putColor(String subString, @ColorRes int colorRes){
    if(getStartEnd(subString)){
        int color = ColorUtil.getColor(context, colorRes);
        ForegroundColorSpan foregroundColorSpan = new ForegroundColorSpan(color);
        fullStringBuilder.setSpan(foregroundColorSpan, startingIndex, endingIndex, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    }
    return this;
}
