试试这个!如果你想将它用于 setText，只需添加 BufferType.SPANANABLE(见下文)

    String redPart = "Hello";
    String bluePart = "World";

    SpannableStringBuilder builder = new SpannableStringBuilder();

    SpannableString redColoredString= new SpannableString(redPart);
    redColoredString.setSpan(new ForegroundColorSpan(Color.RED), 0, redPart.length(), 0);
    builder.append(redColoredString);

    SpannableString blueColoredString= new SpannableString(bluePart);
    blueColoredString.setSpan(new ForegroundColorSpan(Color.BLUE), 0, bluePart.length(), 0);
    builder.append(blueColoredString);


    myEditText.setHint(builder)

    //do following for setText
    myEditText.setText(builder,BufferType.SPANNABLE)
