他のすべてのメソッドが存在しているにもかかわらず、別のクラスのメソッドがEclipseによって存在として認識されないという問題があります。なぜこれが起こっているのか私には分かりませんし、それを理解することもできません。The method getData() is undefined for the type TMXReader.TMXHandler

オートコンプリートは、他のすべてのメソッドを使用可能として表示しますが、何らかの理由でgetDataが「存在しません」...
これは経験豊富なJavaプログラマーには明らかだと思いますが、なぜこれが起こっているのかわかりません...だから、誰かが理由を教えてくれたら、私は感謝するでしょう。ありがとう!
