react-native - KeyboardAvoidingView が React Native アプリに表示されないのはなぜですか?

Question

TextInputコンポーネントを備えたReact Nativeアプリがあります。現時点では、ユーザーがTextInputに入力したときに表示されるKeyboardAvoidingViewを実装しようとしていますが、何も起こっていません。KeyboardAvoidingViewが表示されません。動作プロパティを変更し、絶対位置をコンテナーに配置しましたが、KeyboardAvoidingViewはまだ機能しません。誰かが私に理由を説明できますか？
