Android 一个TextView中字体设置不同颜色和大小

先看效果图：如下

🔶方式一：

1.

String strMsg = "1.我爱<font color=\"#E01919\">我的祖国</font>";
tv.setText(Html.fromHtml(strMsg));

2.

String str1 = "2.我爱<font color= \"#E01919\"><small>我的祖国</small></font>";
tva.setText(Html.fromHtml(str1));

3.

String str2 = "3.我爱<font color=\"#E01919\"><big>我的祖国</big></font>";
tvb.setText(Html.fromHtml(str2));

4.

String str3 = "4.我爱<font color = \"#E01919\"><small><small>我的祖国</small></small></font>";
tvc.setText(Html.fromHtml(str3));

5.

String str4 = "5.我爱<font color=\"#E01919\"><big><big>我的祖国</big></big></font>";
tvd.setText(Html.fromHtml(str4));

6.

String str5 = "我的祖国";
tve.setText(Html.fromHtml("6.我爱" + "<font color=\"#E01919\">" + str5 + "</font>"));

7.

String str6 = "<font color=\"#673AB7\">7.我爱</font><font color=\"#E01919\">我的祖国</font>";
tvf.setText(Html.fromHtml(str6));

8.

String str7 = "<font color=\"#673AB7\">8.我爱</font><br><font color=\"#E01919\">我的祖国</font>";
tvz.setText(Html.fromHtml(str7));

🔶方式二：

最后一行：

String content = "上官小小明回复欧阳小小红：祖国真伟大";

        SpannableStringBuilder builder = new SpannableStringBuilder(content);

        //ForegroundColorSpan 为文字前景色，BackgroundColorSpan为文字背景色
        ForegroundColorSpan buleSpan = new ForegroundColorSpan(Color.parseColor("#4d8ade"));
        ForegroundColorSpan buleSpan1 = new ForegroundColorSpan(Color.parseColor("#4d8ade"));
        ForegroundColorSpan blackSpan = new ForegroundColorSpan(Color.parseColor("#000000"));

        builder.setSpan(buleSpan1, 0, 5, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        builder.setSpan(blackSpan, 5, 7, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
        builder.setSpan(buleSpan, 7, 12, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        builder.setSpan(blackSpan,12, 17, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

        tvh.setText(builder);
