Android棉花糖上TextInputLayout应用程序崩溃的片段

我发现了以下问题。我在XML布局中使用Material Design'class

android.support.Design.widget.TextInputLayout

当我在碎片中膨胀此布局时，我的应用程序会出现以下错误：

android.view.InflateException: Binary XML file line #563: Error inflating class <unknown>

DocumentActivity.java

public class DocumentEditFragment extends BaseFragment {
...
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        View view = inflater.inflate(R.layout.fragment_document_edit, container, false); // The app falls here on Galaxy S7
...
}

public class DocumentActivity extends AppCompatActivity {
    private DocumentEditFragment docEditFragment;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_document);
        docEditFragment = new DocumentEditFragment();
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        ft.replace(R.id.fragment_document, docEditFragment);
        ft.commit();
    }
}
