Question

I want to change respective image of clicked item in recycler view. Now whats happening is if i click on item 2 image is changing at random item position in the list

<         


        

Answer 1

in onBindViewHolder add following code:

testImage.setTag(holder);

then, in onClick add this code to change image:

MyRecyclerViewAdapter.DataObjectHolder  yourHolderObj = (MyRecyclerViewAdapter.DataObjectHolder)((ImageView)itemView.findViewById(R.id.logo)).getTag();

yourHolderObj.testImage.setImageResource(R.drawable.video_icon_fill);

Answer 2

try this,

class CRMbean{
   public boolean isImageChanged;
  public boolean isImageChanged() {
        return isImageChanged;
    }

    public void setImageChanged(boolean imageChanged) {
        isImageChanged = imageChanged;
    }
}

On BindHolder do it like,

@Override
public void onBindViewHolder(MyRecyclerViewAdapter.DataObjectHolder holder, int position) {
    holder.name.setText(mDataset.get(position).getName());
    holder.regId.setText(mDataset.get(position).getRegId());
    holder.roomNo.setText(mDataset.get(position).getRoomNo());
if(mDataset.get(position).isImageChanged()){
    holder.testImage.setImageResource(R.drawable.video_icon_fill);
}else{
     holder.testImage.setImageResource("You Default Image");
}
}

on Adapter write this method

public void changeImage(int index) {
 mDataset.get(position).setImageChanged(true);
   notifyItemChanged(index)

}

On Item click Of Recyleview

 (MyRecyclerViewAdapter) mAdapter).setOnItemClickListener
            (new MyRecyclerViewAdapter.MyClickListener() {
                @Override
                public void onItemClick(int position, View v) {
                    Log.i(LOG_TAG, " Clicked on Item " + position);

               MyRecyclerViewAdapter.changeImage(position);

                }
            });

Answer 3

Change the image value in the object at the clicked position and Call notifyItemChanged(position).Also handle the image change in Bindviewholder(ViewHolder holder,position) method of the Adapter.

Answer 4

Try this:

 @Override 
public void onBindViewHolder(MyRecyclerViewAdapter.DataObjectHolder holder,int position {

holder.name.setText(mDataset.get(position).getName());
holder.regId.setText(mDataset.get(position).getRegId());
holder.roomNo.setText(mDataset.get(position).getRoomNo());
holder.testImage = (ImageView)itemView.findViewById(R.id.log)
holder.testImage.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v) {
         name.setImageResource(Anything you want);
