我已经检查了所有类似的问题（This 和其他问题），但仍然无法找出错误的原因，它在运行时的某个时间点不断关闭......

CategoryDetailFragment.java

/**
 * A simple {@link Fragment} subclass.

    @BindView(R.id.categoryNameTextView) TextView mCategoryNameTextView;
    @BindView(R.id.addPostButton) Button mAddPostButton;
    private Category mCategory;

    public static CategoryDetailFragment newInstance(Category category) {
        CategoryDetailFragment categoryDetailFragment = new CategoryDetailFragment();
        Bundle args = new Bundle();
        args.putParcelable("category", Parcels.wrap(category));
        categoryDetailFragment.setArguments(args);
        return categoryDetailFragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mCategory = Parcels.unwrap(getArguments().getParcelable("category"));
    }


    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container,

        ButterKnife.bind(this, view);

        mCategoryNameTextView.setText(mCategory.getName());
        return view;

错误似乎来自这一行

View view = inflater.inflate(R.layout.fragment_category_detail, container, false);

我已尽我所能，感谢任何帮助...

【问题讨论】：

堆栈跟踪应该有更多内容，例如带有嵌套异常的“Caused by”行。
请从 Logcat 发布完整错误
您的堆栈跟踪被中断 - 请参阅“I/Process：发送信号。PID：27394 SIG：9 应用程序终止。”。您可能想再试一次，看看是否可以获得完整的堆栈跟踪。
@CommonsWare 应用程序关闭“不幸的是，应用程序已停止”，这是完整的错误，或者我缺少什么，请，？
您可以尝试在您的fragment_category_detail.xml 中将@+id/addPostButton 替换为@id/addPostButton

【解决方案1】：

检查是否将片段的布局文件保存为V-24。如果您的最低 SDK 版本低于 24，这可能会导致视图膨胀问题。据我所知，android 中的视图膨胀错误主要是由于特定于版本的布局或可绘制的。

【解决方案2】：

它正在崩溃，因为它无法使用类找到片段，您应该像下面这样提及片段名称

换一个

<fragment
        class = "com.epicodus.talkaboutit.ui.PostListFragment"
        android:id="@+id/postListFragment"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        tools:layout="@layout/fragment_post_list"
        android:layout_below="@+id/categoryNameTextView"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_marginTop="69dp"
        android:layout_above="@+id/addPostButton" />

到这里

 <fragment
            android:name = "com.epicodus.talkaboutit.ui.PostListFragment"
            android:id="@+id/postListFragment"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            tools:layout="@layout/fragment_post_list"
            android:layout_below="@+id/categoryNameTextView"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_marginTop="69dp"
            android:layout_above="@+id/addPostButton" />
