"@+id/timeEdit"レイアウトで定義されたUI 要素view_country.xmlは TextView です。android.widget.TimePickerあなたはあなたの活動でそれをキャストしようとしていますViewCountry。

同じ ID ("@+id/timeEdit") を持つ別の UI 要素があります。これは実際には TimePickerですが、アクティビティのレイアウトに配置されていますAddEditCountry。

レイアウトとコードを確認してください。ViewCountryおそらく要素@+id/timeEditは TextView であってはなりません。または、メソッドで TextView にキャストする必要がありますonCreate。
