在 Android Studio 的数据绑定库中找不到 setHandler 的符号方法

Can not Find Symbol Method for setHandler in Data Binding Library in Android Studio

我在 android studio 中使用数据绑定库,我创建了处理程序来检测 onlcik() 事件我正在使用以下代码

main_activity.xml

<?xml version="1.0" encoding="utf-8"?>
<layout

    </data>
        <RelativeLayout
            android:orientation="vertical"

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


                <include
                        android:layout_height="wrap_content"
                        layout="@layout/grid_layout_carinfo"
                        app:includedViewGroup="@{1}"
                        bind:handlers="@{handlers}"
                        android:layout_width="wrap_content"/>

    </RelativeLayout>
</layout>

grid_layout_carinfo.xml

            <ImageView

                    android:layout_marginTop="8dp"
                    android:onClick="@{(view)->handlers.onCarPhotoFrontView(view)}"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    tools:ignore="ContentDescription" />


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

MainActivity.java

public class MainActivity extends AppCompatActivity {
 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        MainActivityBinding binding = DataBindingUtil.setContentView(this, R.layout.main_activity);


}

    public class MyHandlers {
        public void onClickItem(View view){

        }
    }

}

当我尝试构建项目时出现错误

Error:(134, 29) error: cannot find symbol method setHandler(MainActivity.MyHandlers)

搜索后我发现 bind:handlers="@{handlers}" 中的名称必须与 data 标记中包含的视图中使用的名称相同,清理并重建项目并且它工作
