Android java.lang.IllegalArgumentException:找不到的视图

我正在尝试做什么：从主/细节流项目开始，我尝试使用户能够按下ActionMenu中的一个项目，该项目应该显示一个片段，其中可以放入新数据

问题：我尝试启动片段时出错。我做错了什么

粘贴代码后，我想我把它弄得一团糟。仍然需要帮助

错误：

java.lang.IllegalArgumentException:未找到片段AddItem{5b161e7#1 id=0x7f090040}的id 0x7f090040（com.example.androidtest:id/AddItem_fragment）的视图

从文档中，添加方法：

抽象碎片事务添加（int-containerViewId，碎片碎片）

使用空标记调用add（int、Fragment、String）

在代码中：

public void openAddItem() {
    AddItem additem = new AddItem();
    getSupportFragmentManager().beginTransaction().add(R.id.AddItem_fragment, additem).commit();
}

---

此代码将在您的视图中找到一个id为

R.id.AddItem\u frament

的视图，并尝试将与传递的片段关联的视图附加到该视图上。由于在您的布局中没有用作容器的

视图组

，因此它正在启动一个合法的

IllegalArgumentException

，因为id不存在。您需要做的是提供一个容器，您可以在其中添加所有片段并将此id传递给事务的add方法。

您的问题是这一行

public void openAddItem() {
AddItem additem = new AddItem();
getSupportFragmentManager().beginTransaction()
.add(R.id.AddItem_fragment, additem).commit();
}

你已经在这里了

 <fragment 
android:name="com.example.androidtest.AddItem"
android:id="@+id/AddItem_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp" 
/>

---

希望它足够好

你觉得Actionmenu怎么样？你的意思是？你的片段容器在哪里？通过“提供容器”你的意思是像在fragment.xml中创建RelativeLayout一样吗？我的意思是提供一个视图组，可以是任何RelativeLayout、LinearLayout、FrameLayout。。。使用id AddItem_fragmentI，我尝试像您所说的那样删除上面的代码，异常消失了，但当我按下按钮（触发片段的打开）时，什么也没有发生。也许我搞糟了什么？检查我的编辑，先生，如果它帮助了你，别忘了投票，如果它解决了你所有的问题，请接受@riki oh
