延迟回收者查看每个项目的点击功能

Question

I have a recyclerview . I want to achieve one functionality, but I can't implement it. My RecyclerView item has 2 textView and a button .

public class Task {

private String id;
private String title;

public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}
}

So let me explain a little. The button in my recyclerView item uses stateListDrawable , so it becomes active/inactive on click. When user clicks on a button, and it becomes active, I have to send the item data (title, id) to backend. And when the user clicks on inactive button, I send a delete request to backend for that item. But the problem is that user can click multiple times on the same button and I don't want to send make request every time. Eg I can press the same button 4 times in a second and it becomes active/inactive, so I don't want to make 4-5 requests in a second. What I think, solution is to add a delay on that click events, and eg after 500ms or 1000ms after click send data to backend. I tried to use Handler and actually it worked. Eg when I clicked on 2nd, then 4th and 5th items, after a second of every click, I could send the data to backend. But there is a problem too. When I click on same button multiple times, after a second it sends to backend multiple requests. I've tried to do removeCallbacksAndMessages() on every click before starting the handler, but there is another problem too. Eg When I click multiple times on 2nd item and after that I click on 3rd item, I send only the 3rd item data to backend. But I want to send 2nd and 3rd items data to backend. So can anyone help me to achieve this functionality?

Answer 1

private long mLastClickTime = 0;

...

// inside onCreate or so:

findViewById(R.id.button).setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        // mis-clicking prevention, using threshold of 1000 ms
        if (SystemClock.elapsedRealtime() - mLastClickTime < 1000){
            return;
        }
        mLastClickTime = SystemClock.elapsedRealtime();

        // do your magic here
    }
}
