onItemClick不工作的卡片视图 [英] onItemClick not working for Card View
本文介绍了onItemClick不工作的卡片视图的处理方法，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
它采用2.0改造从Web服务获取数据，并将其绑定到卡片视图。当我点击具有图像和textviews卡视图中，点击没有触发，而是一个奇怪的现象是在卡片视图的onclick是触发的最角落边。

解决方案
首先在适配器中创建界面的一个变量：
CustomItemClickListener mListener;
然后像你在你的的OnClick（）方法设置：
如果（mListener！= NULL）{
mListener.onItemClick（ⅴ，getAdapterPosition（））;
}
，你需要在你的适配器修改的最后一件事是创建新的方法，你会在你的活动类再打处理监听器：
公共无效setOnItemClickListener（CustomItemClickListener监听）{
mListener =侦听器;
}
现在，你可以调用此方法在您的活动是这样的：
adapter.setOnItemClickListener（本）; //实现接口 // 要么adapter.setOnItemClickListener（新CustomItemClickListener（））;
It uses retrofit 2.0 to fetch the data from the webservice and bind it to the card view. When I click on the card view having image and textviews, on click is not triggering, rather a strange behaviour is at the very corner edges of the card view onclick is triggering.

CustomerItemClickListner Interface to handle row item on click
package com.innovation.myapp.jwelleryonrent.model.adapter;
import android.view.View;
/**
*
*/
public interface CustomItemClickListner {
public void onItemClick(View v,int position);
}
解决方案
First create one variable of your interface in your adapter:
CustomItemClickListener mListener;
then like you have set in your OnClick() method:
if (mListener != null) {
mListener.onItemClick(v, getAdapterPosition());
}
and the last thing you need to modify in your adapter is creating new method which you will call later in your activity class for handling listener:
public void setOnItemClickListener(CustomItemClickListener listener) {
mListener = listener;
}
now you can call this method in your activity like this:
adapter.setOnItemClickListener(this); // implement interface
// or
adapter.setOnItemClickListener(new CustomItemClickListener());
