クラッシュやエラーの場合は、スタックトレースを特定してポストします。詳細はこのSOの回答を参照してください。https://stackoverflow.com/questions/3988788/what-is-a-stack-trace-and-how-can-i-use-it-to-debug-my-application-errors –

アプリがクラッシュした場合は、質問にlogcatを追加してください –

logcatが追加されました。 –

あなたはRadioButtonとしてviewをキャストしているが、それは実際にだそれは本当にあなただけのボタンを押し考える意味がありませんがButton

boolean checked = ((RadioButton) view).isChecked();

だから

boolean checked = ((Button) view).isPressed();

を試してみたが、そのクラッシュを引き起こしているものです。
