我只得到＆＃39; HL＆＃39;作为输出。

Answer 1

使用输出

进行检查

  SpannableString text = new SpannableString("RAHUL");
        text.setSpan(new ForegroundColorSpan(Color.WHITE), 0, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        text.setSpan(new ForegroundColorSpan(Color.BLUE), 3, 5, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

        tv.setText(text);

棉花糖上的输出

希望它能帮到你

Answer 2

您的开始和结束参数对于第二个setSpan：

是错误的

SpannableString text = new SpannableString("RAHUL");
text.setSpan(new ForegroundColorSpan(Color.WHITE), 0, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
text.setSpan(new ForegroundColorSpan(Color.BLUE), 3, 5, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
headerHolder.mTextViewLabel.setText(text, TextView.BufferType.SPANNABLE);

Answer 3

试试这个可能对你有所帮助变化

    text.setSpan(new ForegroundColorSpan(white), 0, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    text.setSpan(new ForegroundColorSpan(blue), 3, 5, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

而不是

    text.setSpan(new ForegroundColorSpan(white), 0, 2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    text.setSpan(new ForegroundColorSpan(blue), 3, 4, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

我想在Marshamallow上使用spannable。它给我不正确的输出
