Recyler视图项仅获取上单击文本选择 [英] Recyler view item gets selected only on clicking the text
本文介绍了Recyler视图项仅获取上单击文本选择的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经实现了RecyclerView与项目适配器和每个项目都有包含的ImageView和一个TextView抽屉的项目布局。结果
问题是，被点击仅当图像或不同的大小的实际文本，而不是整个行的onClick函数。结果，
有没有一种方法，使全行的onClick与功能听呢？请让我知道，如果你有任何想法。
先谢谢了。结果
I have implemented the RecyclerView with an adapter for items and each item has a drawer item layout containing an imageview and a textview.
The problem is that the onClick function is called only when the image or the "actual text" which differs in size is clicked and not the whole row.
Is there a way to make to whole row listen with onClick function? Please let me know if you have any ideas.
Thanks in advance.

推荐答案
在适配器的 onCreateViewHolder（）方法，将膨胀（）调用如下：
In the Adapter's onCreateViewHolder() method, change the inflate() calls as follows.
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);
}
您行不匹配 RecyclerView 的宽度，因为你不及格父来的充气器，所以它的包装纸宽度来代替。
Your rows aren't matching the RecyclerView's width, because you're not passing parent to the Inflater, so it's wrapping the width instead.
