单击其中一个抽屉菜单后应用程序停止工作
Application stop working after clicking on one of drawer menus
我正在学习如何使用抽屉更改不同菜单中的片段，但是当我使用脚本单击菜单时，它是 "Unfortunately, DrawerTest2 has stopped"
谁能看看我的代码，看看我做错了什么？

有人知道我做错了什么吗？这是我的第一个应用程序，所以我可能做错了。
谢谢！
您没有用另一个替换您的 content_main 布局。您希望您的 content_main 有一个像这样的片段容器：
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
在您的代码中，您应该使用此代码片段将您的片段放入 FrameLayout：
getSupportFragmentManager().beginTransaction()
.replace(R.id.fragment_container,fragment)
.commit();
在你的情况下，将你的 content_main 布局复制到另一个文件，比如 first_fragmet.xml。为它创建另一个片段并像在 SMSFragment 中那样膨胀它。
在您的 activity 的 onCreate() 方法中，使用上述代码放置第一个片段。例如
fragment = new FirstFragment();
getSupportFragmentManager().beginTransaction()
.replace(R.id.fragment_container,fragment)
.commit();
当您希望用 SMSFragment 替换当前视图时，只需使用上面相同的代码，但使用 fragment 作为您的 SMSFragment 对象。
有关详细信息，请参阅 this tutorial。
我正在学习如何使用抽屉更改不同菜单中的片段，但是当我使用脚本单击菜单时，它是 "Unfortunately, DrawerTest2 has stopped"
谁能看看我的代码，看看我做错了什么？

有人知道我做错了什么吗？这是我的第一个应用程序，所以我可能做错了。
谢谢！
您没有用另一个替换您的 content_main 布局。您希望您的 content_main 有一个像这样的片段容器：
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
在您的代码中，您应该使用此代码片段将您的片段放入 FrameLayout：
getSupportFragmentManager().beginTransaction()
.replace(R.id.fragment_container,fragment)
.commit();
在你的情况下，将你的 content_main 布局复制到另一个文件，比如 first_fragmet.xml。为它创建另一个片段并像在 SMSFragment 中那样膨胀它。
在您的 activity 的 onCreate() 方法中，使用上述代码放置第一个片段。例如
fragment = new FirstFragment();
getSupportFragmentManager().beginTransaction()
.replace(R.id.fragment_container,fragment)
.commit();
当您希望用 SMSFragment 替换当前视图时，只需使用上面相同的代码，但使用 fragment 作为您的 SMSFragment 对象。
