Fast taps (clicks) on RecyclerView opens multiple Fragments

Question

I have implemented onClick listener to my ViewHolder for my RecyclerView

But when I perform very fast double taps or mouse clicks, it performs the task (opens a seperate fragment in this case) twice or three times.

here is my code

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

    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) {
        mListener.onClick(FRAGMENT_VIEW, getAdapterPosition()); // open FRAGMENT_VIEW
    }
}

Any ideas on how to prevent such behaviour?

Answer 1

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
    }
}
