当我使用Android数据绑定include在我的xml文件中的非根元素中使用标记时,应用程序崩溃.但是当标记放在根元素中或没有数据绑定时,应用程序运行良好.include

这是我的源代码,任何人都可以帮我弄清楚原因吗？

activity_main.xml中

<layout>

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        tools:context=".MainActivity">


        <TextView
            android:id="@+id/text_view"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/hello_world" />

        <LinearLayout

            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <include layout="@layout/include_layout" />

        </LinearLayout>
    </LinearLayout>
</layout>

MainActivity.java

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
        binding.textView.setText("hello world");
    }
}
