【问题描述】：
所以我正在开发一个需要并排显示 2 个片段并且仍然可以选择使用这样的导航抽屉的 Android 应用 Image link can't post images :(
我的问题是，当我尝试将任何片段添加到 xml 文件中时，我收到以下错误

我的 MainActivity 看起来像这样
由于尺寸限制，转为喜欢
past bin link code to version 1 off MainActity moved
我一直在尝试更改活动以扩展 fragmentActivity 而不是关闭活动女巫没有工作:( 我也一直在尝试将 2 个片段移动到不同的 xml 文件中，并将内容设置为新的 xml 不起作用:(也许我犯了一些愚蠢的错误我真的不擅长 android 布局:(
如果我只从 MainActivity 添加片段但不显示第二个片段，我的应用程序可以正常工作...第二个我将片段添加到 xml 代码中，我的应用程序在启动时崩溃
编辑
仍然没有进展:( 我一直在托盘上更改布局，甚至设置一个全新的布局文件，仍然在托盘上保留导航抽屉，但仍然出现相同的崩溃错误:(
有什么想法吗？？
编辑 2 由于大小限制，迫使我从 MainActivity 中删除第一个版本
所以我在重播后搜索了更多内容。 我将所有导入更改为
android.support.v4.app.
witch 没有任何区别，所以我开始运行调试器来查看应用程序在该行失败的 linje 是什么
setContentView(R.layout.drawfragment);
所以这让我认为我可能会将 setcontent 更改为包含相对布局的另一个 xml，并且 2 个片段给出了相同的错误，所以我托盘删除了 2 个片段，女巫给了我一个错误，人托盘创建导航抽屉。
有人有解决这个问题的方法吗？？由于我需要一些不同的方法来创建导航抽屉？
新的 MainActivity 看起来像这样很多偏离主题已经改变，但在主题相关代码中没有太大差异

【问题讨论】：
-
您确定您的
Fragments在com.example.evemanufacturing3.app包中可用吗？ -
java 应用程序文件放在 com.example.evemanufacturing3.app 中，所有 xml 文件都放在 res/layout 中
