使用Kotlin和扩展，您可以添加彩色文本非常简单和干净:

创建一个TextViewExtensions文件。Kt和这个含量

fun TextView.append(string: String?, @ColorRes color: Int) {
    if (string == null || string.isEmpty()) {
        return
    }

    val spannable: Spannable = SpannableString(string)
    spannable.setSpan(
        ForegroundColorSpan(ContextCompat.getColor(context, color)),
        0,
        spannable.length,
        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
    )

    append(spannable)
}

现在很容易添加文本的颜色

textView.text = "" // Remove old text
textView.append("Red Text", R.color.colorAccent)
textView.append("White Text", android.R.color.white)

基本上与@Abdul Rizwan的答案相同，但使用Kotlin，扩展，一些验证和在扩展内部获得颜色。

是的，如果你用html的font-color属性格式化字符串，然后把它传递给方法html . fromhtml(你的文本在这里)

String text = "<font color=#cc0029>First Color</font> <font color=#ffcc00>Second Color</font>";
yourtextview.setText(Html.fromHtml(text));

最好使用strings文件中的字符串，如下所示:

    <string name="some_text">
<![CDATA[
normal color <font color=\'#06a7eb\'>special color</font>]]>
    </string>

用法:

textView.text=HtmlCompat.fromHtml(getString(R.string.some_text), HtmlCompat.FROM_HTML_MODE_LEGACY)

使用SpannableStringBuilder

SpannableStringBuilder builder = new SpannableStringBuilder();

SpannableString str1= new SpannableString("Text1");
str1.setSpan(new ForegroundColorSpan(Color.RED), 0, str1.length(), 0);
builder.append(str1);

SpannableString str2= new SpannableString(appMode.toString());
str2.setSpan(new ForegroundColorSpan(Color.GREEN), 0, str2.length(), 0);
builder.append(str2);

TextView tv = (TextView) view.findViewById(android.R.id.text1);
tv.setText( builder, TextView.BufferType.SPANNABLE);

我是这样做的:

通过传递String和Color在文本上设置颜色:

private String getColoredSpanned(String text, String color) {
    String input = "<font color=" + color + ">" + text + "</font>";
    return input;
}

通过调用下面的代码设置TextView / Button / EditText等文本:

TextView:

TextView txtView = (TextView)findViewById(R.id.txtView);

获取彩色字符串:

String name = getColoredSpanned("Hiren", "#800000");
String surName = getColoredSpanned("Patel","#000080");

在TextView上设置两个不同颜色的字符串的文本:

txtView.setText(Html.fromHtml(name+" "+surName));

Done

让普通函数转换你的字符串是可扩展的，像这样。

//pass param textviewid ,start,end,string
//R.color.Red it's your color you can change it as requirement

fun SpannableStringWithColor(view: TextView,start:Int,end:Int, s: String) {
    val wordtoSpan: Spannable =
        SpannableString(s)
    wordtoSpan.setSpan(
        ForegroundColorSpan(ContextCompat.getColor(view.context, R.color.Red)),
        start,
        end,
        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
    )
    view.text = wordtoSpan
    }

像这样的要求我们可以在任何地方使用。

 SpannableStringWithColor(tvMobileNo,0,14,"Mobile Number :   " + "123456789")

 SpannableStringWithColor(tvEmail,0,5,"Email :   " + "abc@gmail.com" "))

 SpannableStringWithColor(tvAddress,0,8,"Address :   " + "Delhi India")
