Android 2.1 にはアラビア語フォントがありません。
Android 2.2 にはアラビア語のフォントがありますが、単語が正しく表示されません。
Android 3.x はアラビア語を完全にサポートしています。
Android 2.1の場合、書体Farsi.GetFarsiFont(this)
を設定してから使用する必要がありますFarsi.Convert("سلام")
Android 2.2の場合、フォントを設定する必要はありませんが、Farsi.Convert("سلام")を使用する必要があります。
Android 3.xの場合は、上記の解決策をすべて忘れてください ;)。ただし、3.x のアラビア語フォントが気に入らない場合は、フォントを変更できます。
次の手順を実行します。
1)まずはassetsフォルダに「TAHOMA.TTF」を追加
2) 次のクラスを使用してフォントを取得し、アラビア語またはペルシア語のテキストをアクティビティで表示するのに適した形式に変換します。
