Я прочитал эту проблему и до сих пор не могу понять, почему я получаю ту же ошибку.
У меня есть FrameLayout, который я позже буду использовать для некоторых Fragment, и LinearLayout, который описывает мой левый ящик, оба они обернуты в какой-то другой LinearLayout, который вы можете увидеть ниже в xml.
Я применил предложенные ответы, а именно, настройку для android:gravity="left" для LinearLayout, который описывает ящик, все та же ошибка.
Ошибка, которую я получаю:
Caused by: java.lang.IllegalArgumentException: View android.widget.LinearLayout{77c3762 V.E...... ......I. 0,0-0,0 #7f070059 app:id/drawerPane} is not a sliding drawer
Я также пытался установить ListView android:layout_gravity="left", опять же ошибка.
