Fast taps (clicks) on RecyclerView opens multiple Fragments

You can modify it like this.

public class ViewHolder extends RecyclerView.ViewHolder implements
        View.OnClickListener {
    TextView tvTitle, tvDescription;
    private long mLastClickTime = System.currentTimeMillis();
    private static final long CLICK_TIME_INTERVAL = 300;

    public ViewHolder(View itemView) {
        super(itemView);
        itemView.setClickable(true);
        itemView.setOnClickListener(this);

        tvTitle = (TextView) itemView.findViewById(R.id.tv_title);
        tvDescription = (TextView) itemView
                .findViewById(R.id.tv_description);
    }

    @Override
    public void onClick(View v) {
        long now = System.currentTimeMillis();
        if (now - mLastClickTime < CLICK_TIME_INTERVAL) {
            return;
        }
        mLastClickTime = now;
        mListener.onClick(FRAGMENT_VIEW, getAdapterPosition()); // open
                                                                // FRAGMENT_VIEW
    }
}

If you are using Kotlin you can go with this based on Money's answer

class CodeThrottle {
    companion object {
        const val MIN_INTERVAL = 300
    }
    private var lastEventTime = System.currentTimeMillis()

    fun throttle(code: () -> Unit) {
        val eventTime = System.currentTimeMillis()
        if (eventTime - lastEventTime > MIN_INTERVAL) {
            lastEventTime = eventTime
            code()
        }
    }
}

Create this object in your view holder

    private val codeThrottle = CodeThrottle()

Then do the following in your bind

name.setOnClickListener { codeThrottle.throttle { listener.onCustomerClicked(customer, false) } }

Putting whatever code you need called in place of

listener.onCustomerClicked(customer, false) 

The most straightforward approach here would be using setMotionEventSplittingEnabled(false) in your RecyclerView.

By default, this is set to true in RecyclerView, allowing multiple touches to be processed.

When set to false, this ViewGroup method prevents the RecyclerView children to receive the multiple clicks, only processing the first one.

See more about this here.

This is a very annoying behavior. I have to use an extra flag to prevent this in my work.

public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
TextView tvTitle, tvDescription;
private boolean clicked;

public ViewHolder(View itemView) {
    super(itemView);
    itemView.setClickable(true);
    itemView.setOnClickListener(this);

    tvTitle = (TextView) itemView.findViewById(R.id.tv_title);
    tvDescription = (TextView) itemView.findViewById(R.id.tv_description);
}

@Override
public void onClick(View v) {
    if(clicked){
        return;
    }
    clicked = true;
    v.postDelay(new Runnable(){
          @Override
          public void run(View v){
              clicked = false;
          }
    },500);
    mListener.onClick(FRAGMENT_VIEW, getAdapterPosition()); // open FRAGMENT_VIEW
}
}
