そしてupgrade_buttonのための画面は、XMLを下回っている：

> <Button android:id="@+id/upgrade_button" 
>   android:layout_width="fill_parent" 
>   android:layout_height="wrap_content" 
>   android:text="@string/button_textbuypremium" 
>   android:onClick="onUpgradeAppButtonClicked" 
>   style="@style/BlackText" 
>   android:background="@color/orange" 
>   
>   android:layout_marginTop="25dip"/> 

その他

ボタンを押して、それが大丈夫ですが、IlegalSateExceptionを発行した "upgrade_button"だけをクリックします。

問題はどこですか？

Answer 1

いくつかの "setwaitscreen"と "void setWaitScreen（boolean set）"を削除/コメントすると、ビューが利用できないため、エラーが消えました。 Mikeに案内されてくれてありがとう。
