我检查了所有类似的问题(This和其他问题)，但仍然找不出错误的原因，它在运行时的某个时刻一直关闭.

CategoryDetailFragment.java

/**
 * A simple {@link Fragment} subclass.
 */
public class CategoryDetailFragment extends Fragment implements View.OnClickListener{
    @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,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_category_detail, container, false);
        ButterKnife.bind(this, view);
        mAddPostButton.setOnClickListener(this);

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

fragment_category_detail.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"

这个错误似乎来自于这一行

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

我已经尽我所能了，任何帮助都很感激.

检查是否将片段的布局文件保存为V-24。如果您的最低SDK版本小于24，则可能会导致视图膨胀方面的问题。据我所知，安卓系统中出现的视图通胀错误主要是由于版本特定的布局或可绘制。

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到片段名

换这个

<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" />

到这个

 <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" />
