我通过我的自定义recyclelerview适配器给我的卡片视图充气。现在，我想知道如何在su，mo，tu，we，th，fr，sa位置上从我的adpater类设置点击监听器。
我想要一个数组，如果用户在cardview的0位置点击su，mo，tu，那么数组应该如下[1,2,3]
并在第一个位置用户点击了我们，然后，我应该得到另一个数组如下[4,5,6]
目前来自我的适配器我已经参考了这些textview并添加了点击监听器，但即使选择不同，我也会获得两个位置相同的数组。
我的适配器类a如下。

你可以得到这样的位置：
@Override
public void onClick(View view) {
int position = getAdapterPosition();
//do something depending on the position
//...
}

考虑到您的浏览器已经拥有与工作日相关的View对象，您可以轻松地向您的adaper添加自定义多选代码。 （可能有更简单的方法来做到这一点，但我正在为你提出的问题提供一个可能的答案）
//decalare this instance variables in your adapter
//better to go for a hash map but I'm just writing an example
int itemPosition=-1;
List<Integer> selectedDays;
//initiate the list in the adapter constructor
selectedDays=new ArrayList<>();
//make this change in your onBindViewHolder()
StudentViewHolder sHOlder=(StudentViewHolder)holder;
List<TextView> dayViews=new ArrayList<>();
dayView.add(sHolder.mSundayButton);
//continue this and fill the list with all the seven buttons
//check the previously created selectedDays list and set the colors for selected text views
if(postion==itemPosition){
for(int i=1;i<8;i++){
TextView tv=dayViews.get(i-1);
if(selectedList.contains(new Integer(i))){
tv.setTextColor(/*your selected color*/);
}else{
tv.setTextColor(/*your unselected color*/);
}
}
}else{
for(TextView tv:dayViews){
tv.setTextColor(/* your unselectedColor */);
}
}
//now implement onclicks for the days;
for(int i=0;i<dayViews.length;i++){
TextView tv=dayViews.get(i);
tv.setOnClickListener(new View.OnCLickListener{
@Override
public void onClick(View v){
//clear the list if the item position has changed
if(position!=itemPosition){
selectedDays.clear();
}
itemPosition=position;
selectedDays.add(i+1);
//notify the adapter
notifyDataSetChanged();
}
});
}
//you can convert the list to an array when you want to take the data
int[] returnArray=new Int[selectedDays.size()];
for(int i=0;i<selectedDays.size;i++){
returnArray[i]=selectedDays.get(i);
}
答案 2 :(得分：0)
结果是一样的，因为您在一个数组列表中为每个项目设置数据（即）mDaysArrayList。
您应该分别为每个项目创建mDaysArrayList。 为项目创建课程是更好的做法。并将所选日期的arrayList放在此类中。

最简单的方法是在viewHolder.itemView.setOnClickListener(listner)内拨打onBindViewHolder，如下所示：
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
holder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
}
