适配器：

    this.list=list;
    this.calllog_items=calllog_item;
    list.addOnItemTouchListener(new RecyclerItemClickListener(c, list ,new RecyclerItemClickListener.OnItemClickListener() {

            Button call= (Button) view.findViewById(R.id.call_txt);

Answer 1

您是否尝试将其设置为可引用且可聚焦？

XML

android:focusable="true"
android:clickable="true"

爪哇

button.setClickable("true");
button.setFocusable("true");

如果没有任何变化，请尝试在onClick方法中进行日志调用（可能代码中存在不良内容），或者在OnTouch中。

按钮不会在Recyclerview项目中获得焦点
