Html.fromHtmlは、サポートしているタグについてほとんど何の証拠もありません。Html.fromHtml関数の "font"タグで使用できるフォントフェイスはどれですか？
多くのウェブサイト（例えばなど）の "font"タグをサポートしていると書かれていますが、このタグ内に "face"属性を設定するときはどのフォントが使用できるかわかりません。
常に利用可能なフォントはどれですか？特定のAndroidバージョンのみのものはどれですか？それらのリストはどこかにありますか？
編集：答えは "/system/etc/fonts.xml"ファイルにあるはずです。ここでのAndroid 6.0.1へのコンテンツです：
textView.setText(Html.fromHtml("Normal <br/>" +
"<font face='sans-serif'>sans-serif</font> <br/>" +
"<font face='sans-serif-thin'>sans-serif-thin</font> <br/>" +
"<font face='sans-serif-light'>sans-serif-light</font> <br/>" +
"<font face='sans-serif-medium'>sans-serif-medium</font> <br/>" +
"<font face='sans-serif-black'>sans-serif-black</font> <br/>" +
"<font face='sans-serif-condensed'>sans-serif-condensed</font> <br/>" +
"<font face='sans-serif-condensed-light'>sans-serif-condensed-light</font> <br/>" +
"<font face='serif'>serif</font> <br/>" +
"<font face='monospace'>monospace</font> <br/>" +
"<font face='serif-monospace'>serif-monospace</font> <br/>" +
"<font face='casual'>casual</font> <br/>" +
"<font face='cursive'>cursive</font> <br/>" +
"<font face='sans-serif-smallcaps'>sans-serif-smallcaps</font> <br/>" +
"<font face='elegant'>elegant</font> <br/>" +
"<font face='compact'>compact</font> <br/>"
));
そして、ここでの結果である：

'fromHtml（）'は 'command'ではないことを指摘する必要があります。これは 'メソッド'です。 –
解析のために、Android 6.0を介して ''の 'face'属性が' TypefaceSpan'のコンストラクタに直接渡されます。したがって、 'TypefaceSpan'がサポートしているのはあなたが使用できるものです。 'Spanned'からのHTML生成では、' 'への' monospace'マッピングだけをサポートしています。 – CommonsWare
@MarcinOrlowski実際には、クラスのインスタンスのメンバーではないので、静的関数であり、メソッドではありません。私はより一般的なものとして "コマンド"を書いたが、それを "機能"に変更した。 –
