我正在我的应用中实现BottomNavigationView。它在模拟器中工作正常，但当我尝试在真正的移动设备时崩溃应用程序。我也在主要活动中使用viewpager来刷滑动导航物品。我也检查gradle依赖，但仍然崩溃。和Android版本的模拟器和手机都是一样的。

答案 0 :(得分：0)
检查您的应用build.gradle文件并确保appcompat和设计库版本相同，如果版本不同则可能会崩溃
compile 'com.android.support:appcompat-v7:23.1.1' // appcompat library
compile 'com.android.support:design:23.1.1' //design support library
答案 1 :(得分：0)
我唯一看到的可能不正确的是
的结束括号（/＆gt;）<android.support.design.widget.BottomNavigationView.
在某些文本编辑器（例如atom）中，需要使用左括号进行对齐。这也正是你的错误所在，所以试一试是个不错的主意。
或者，在底部通过完全写出来关闭它。例如</android.support.design.widget.BottomNavigationView>。
