Kotlin-Androidの2つのAdapterクラスに貢献し、DataBindingと従来のAdapterを組み合わせます.

開発の過程で、私たちはリストを使用することがよくあります.もちろん、Adapterは自然によく使用されています.そのため、Adapterをパッケージ化する必要があります.そうすれば、開発に適応することができます.具体的にはコード実装を見てみましょう.質問があればQQ 407158004にお問い合わせください.-)
まず、コードには注釈クラスが含まれています.主にビューマッピングに使用されます.以下のようにします.

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * Created by mrper on 17-3-14.
 *   Adapter ItemView    
 */
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface ItemView {

    /**   ID **/
    int value();

}
