Пожалуйста, разместите свой макет деятельности xml – Neil

Возможно, вам нужно изменить тему активности в манифесте или в файле styles.xml ... Можете ли вы добавить оба вопроса на свой вопрос, пожалуйста? –

+1

Либо это, либо 'findViewById (R.id.toolbar);' возвращает null, потому что у вас нет идентификатора панели инструментов в файле макета –

Вы не определили виджет Toolbar в своем текстовом файле Activity. Вам нужно будет добавить что-то вроде этого, чтобы избавиться от NullPointerException.

<android.support.design.widget.AppBarLayout 
     android:id="@+id/appBarLayout" 
     android:layout_width="match_parent" 
     android:layout_height="@dimen/app_bar_height" 
     android:background="@color/transparent" 
     android:theme="@style/AppTheme.AppBarOverlay" 
     app:elevation="0dp"> 

     <android.support.v7.widget.Toolbar 
      android:id="@+id/toolbar" 
      android:layout_width="match_parent" 
      android:layout_height="55dp" 
      android:layout_marginTop="@dimen/app_bar_height" 
      android:background="@color/transparent" 
      app:popupTheme="@style/AppTheme.PopupOverlay" /> 
    </android.support.design.widget.AppBarLayout>

Это еще не конец ваших проблем. Я вижу, что ваш код ищет drawer layouts и другие вещи , которые не определены в вашем xml ... Вам также придется исправить это.

OMG я забыл об этом хахаха, спасибо, ребята решили :) –

+0

Просто примечание: 'AppBarLayout' не требуется, если нет дополнительных макетов для добавления рядом с панелью инструментов –

+0

@ cricket_007 true, вам это не нужно (честно говоря, я просто использовал урезанную, скопирующую версию моего собственного кода). – Neil
