[否查看发现ID＆QUOT; - Android的碎片 [英] "No View Found For ID" - Android Fragment

问题描述

所以我工作的一个应用程序的朋友，它总是崩溃，无法到我的设备（一加手机）上运行

So I'm working on an app for a friend and it keeps crashing and is unable to run on my device (OnePlus One).

我一直在这里得到一个错误说不认为找到标识：

I keep getting an error here saying "No view found for id":

我有两个班;一类NavigationDrawer（这是我基本上是我的MainActivity）：

I have two classes; a NavigationDrawer class (which is my essentially my MainActivity):

和一个名为StartingFragment类（我想是当抽屉被关闭/没有激活主视图）。

And a class named StartingFragment (which I want to be the main view when the drawer is closed/not active).

下面是code，其中有一个错误（从NavDrawer.java）：

Here is the code in which there is an error (from NavDrawer.java):

        /** Swaps fragments in the main content view */
        /** Starts an Activity when item is clicked */
        private void selectItem(int position) {
                // Create a new fragment and specify the tea type
                // to show based on position
                Fragment fragment = new StartingFragment();
                Bundle args = new Bundle();
                args.putInt(StartingFragment.TEA_TYPE_POS, position);
                fragment.setArguments(args);

                // Insert the fragment by replacing any existing fragment
                FragmentManager fragManager = getFragmentManager();
                fragManager.beginTransaction().replace(R.id.starting_fragment, fragment)
                                .commit();

                // Highlight the selected item, update the title, and close the drawer
                mDrawerList.setItemChecked(position, true);
                setTitle(navDrawerTitles[position]);
                navDrawerLayout.closeDrawer(mDrawerList);

        }

我看了遍计算器，我看到其他的是如何得到这个错误，但我不能完全肯定为什么我不断收到此错误，或如何解决它。

I've looked all over StackOverflow and I see how other's are getting this error, but I'm not entirely sure of why I keep getting this error, or how to fix it.

我在这里看到了这个问题：
http://stackoverflow.com/a/8158916 以及我看到的 R.id.starting_fragment 应是的孩子的在 R.layout.nav_drawer 的。

I looked at this question here: http://stackoverflow.com/a/8158916 and I see that R.id.starting_fragment should be a child of the R.layout.nav_drawer.

不过，我不知道在我的code调整。我应该删除我的按钮，然后有片段code在我的 nav_drawer.xml ？像这样的：

However, I don't know what to adjust in my code. Should I remove the Buttons I have and then have fragment code in my nav_drawer.xml? Such as this:

<fragment android:name="com.fv4.app.StartingFragment"
              android:id="@+id/starting_fragment"
              android:layout_width="0dp"
              android:layout_height="match_parent" />

还是真的......我应该怎么来替换 R.id.starting_fragment 在我的code？

推荐答案

在你给你的活动XML没有什么用id'starting_fragment因此没有更换，在XML的活动，需要有一个查看/布局/ fragmentContainer用id'starting_fragment。还你有点糊涂了，该标识在.replace（）方法重新presents你要替换片段没有布局的事情

In the xml you gave for your activity there's no nothing with the id 'starting_fragment' therefore nothing to replace, in the xml for the activity there needs to be a view/layout/fragmentContainer with the id 'starting_fragment'. Also you're a bit confused, the Id in the .replace() method represents the thing you're going to replace not the layout of the fragment

简单的修复

在XML的活动创造的FrameLayout，给它的IDfragment_replace

in xml for the Activity create a frameLayout, give it the id 'fragment_replace'

更改.replace（R.id.starting_fragment，片段）以.replace（R.id.fragment_replace，片段）

Change .replace(R.id.starting_fragment,fragment) to .replace(R.id.fragment_replace,fragment)
