Question

我已经使用适配器实现了RecyclerView项目，每个项目都有一个包含imageview和textview的抽屉项目布局。
问题是仅当单击图像或大小不同的“实际文本”而不是整行时才调用onClick函数。
有没有办法用onClick函数进行整行监听？如果您有任何想法，请告诉我。提前谢谢。

Answer 1

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

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，因此它会包裹宽度代替。

Answer 2

你可以试试这个在您的情况下将线性布局设置为RecyclerView的父布局，并在View支架中绑定此布局，并将onclick设置为此布局，它应该可以使用

只有在单击文本时才会选择Recyler视图项
