String newMessageInfo = "我正在<font color='red'>" + "紅色內容"

+ "</font>TextView學習顯示不同顏色";

textView.setText(Html.fromHtml(newMessageInfo));

方法二：

textView = (TextView) findViewById(R.id.textview);

SpannableStringBuilder builder = new SpannableStringBuilder(textView.getText().toString());

//ForegroundColorSpan 爲文字前景色，BackgroundColorSpan爲文字背景色

ForegroundColorSpan redSpan = new ForegroundColorSpan(Color.RED);

ForegroundColorSpan whiteSpan = new ForegroundColorSpan(Color.WHITE);

ForegroundColorSpan blueSpan = new ForegroundColorSpan(Color.BLUE);

ForegroundColorSpan greenSpan = new ForegroundColorSpan(Color.GREEN);

ForegroundColorSpan yellowSpan = new ForegroundColorSpan(Color.YELLOW);

builder.setSpan(redSpan, 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

builder.setSpan(whiteSpan, 1, 2, Spannable.SPAN_INCLUSIVE_INCLUSIVE);

builder.setSpan(blueSpan, 2, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

builder.setSpan(greenSpan, 3, 4, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

builder.setSpan(yellowSpan, 4,5, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
