@Swapnil Kotwal回答的Kotlin版本。

Android Studio 4.0.1, Kotlin 1.3.72

val greenText = SpannableString("This is green,")
greenText.setSpan(ForegroundColorSpan(resources.getColor(R.color.someGreenColor), null), 0, greenText.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
yourTextView.text = greenText

val yellowText = SpannableString("this is yellow, ")
yellowText.setSpan(ForegroundColorSpan(resources.getColor(R.color.someYellowColor), null), 0, yellowText.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
yourTextView.append(yellowText)

val redText = SpannableString("and this is red.")
redText.setSpan(ForegroundColorSpan(resources.getColor(R.color.someRedColor), null), 0, redText.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
yourTextView.append(redText)

你可以使用Spannable应用效果到你的TextView:

这是我的例子，只是一个TextView文本的第一部分上色(同时允许您动态设置颜色，而不是硬编码成字符串与HTML的例子!)

    mTextView.setText("Red text is here", BufferType.SPANNABLE);
    Spannable span = (Spannable) mTextView.getText();
    span.setSpan(new ForegroundColorSpan(0xFFFF0000), 0, "Red".length(),
             Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

在这个例子中，你可以将0xFFFF0000替换为getResources().getColor(R.color.red)

你可以在没有HTML的情况下打印多种颜色的行:

TextView textView = (TextView) findViewById(R.id.mytextview01);
Spannable word = new SpannableString("Your message");        

word.setSpan(new ForegroundColorSpan(Color.BLUE), 0, word.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

textView.setText(word);
Spannable wordTwo = new SpannableString("Your new message");        

wordTwo.setSpan(new ForegroundColorSpan(Color.RED), 0, wordTwo.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.append(wordTwo);

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

试试这个:

mBox = new TextView(context);
mBox.setText(Html.fromHtml("<b>" + title + "</b>" +  "<br />" + 
      "<small>" + description + "</small>" + "<br />" + 
      "<small>" + DateAdded + "</small>"));

我已经这么做了，试试吧:

TextView textView=(TextView)findViewById(R.id.yourTextView);//init

//here I am appending two string into my textView with two diff colors.
//I have done from fragment so I used here getActivity(), 
//If you are trying it from Activity then pass className.this or this; 

textView.append(TextViewUtils.getColoredString(getString(R.string.preString),ContextCompat.getColor(getActivity(),R.color.firstColor)));
textView.append(TextViewUtils.getColoredString(getString(R.string.postString),ContextCompat.getColor(getActivity(),R.color.secondColor)));

在你的TextViewUtils类中添加这个方法:

 /***
 *
 * @param mString this will setup to your textView
 * @param colorId  text will fill with this color.
 * @return string with color, it will append to textView.
 */
public static Spannable getColoredString(String mString, int colorId) {
    Spannable spannable = new SpannableString(mString);
    spannable.setSpan(new ForegroundColorSpan(colorId), 0, spannable.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    Log.d(TAG,spannable.toString());
    return spannable;
}
