Recyclerview 项目仅在单击文本时被选中

Question

我已经实现了带有项目适配器的 RecyclerView，每个项目都有一个包含图像视图和文本视图的抽屉项目布局。
问题是 onClick 函数仅在单击图像或大小不同的 "actual text" 而不是整行时被调用。
有没有办法让整行用 onClick 函数监听？如果您有任何想法，请告诉我。提前致谢。

Answer 1

你可以试试这个在您的情况下为 RecyclerView 的父布局设置一个 id 线性布局并将此布局绑定到视图持有者并将 onclick 设置为此布局它应该工作

Answer 2

在适配器的 onCreateViewHolder() 方法中，按如下方式更改 inflate() 调用。

if(viewType == 1) {
    View itemLayout = layoutInflater.inflate(R.layout.drawer_item_layout, parent, false);
    return new ViewHolder(itemLayout, viewType, context);
}
else if(viewType == 0) {
    View itemHeader = layoutInflater.inflate(R.layout.header_layout, parent, false);
    return new ViewHolder(itemHeader, viewType, context);
}

您的行与 RecyclerView 的宽度不匹配，因为您没有将 parent 传递给 Inflater，所以它换行了宽度。
