Android Preventing Double Click On A Button

Question

What is the best way to prevent double clicks on a button in Android?

Answer 1

You can use this method. By using post delay you can take care for double click events.

void debounceEffectForClick(View view) {

    view.setClickable(false);

    view.postDelayed(new Runnable() {
        @Override
        public void run() {
            view.setClickable(true);

        }
    }, 500);
}

Answer 2

We could use the button just synchronized like:

@Override
public void onClick(final View view) {
    synchronized (view) {

        view.setEnabled(false);

        switch (view.getId()) {
            case R.id.id1:
                ...
                break;
            case R.id.id2:
                ...
                break;
                ...
        }

        new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {
                view.setEnabled(true);
            }
        }, 1000);
    }
}

Good Luck)

Setting Clickable to false does not work on the first double click but subsequent double clicks are blocked. It is as though the loading click delegate the first time is slower and the second click is captured before the first completes.

        Button button = contentView.FindViewById<Button>(Resource.Id.buttonIssue);
        button.Clickable = false;
        IssueSelectedItems();
        button.Clickable = true;

Answer 4

saving a last click time when clicking will prevent this problem.

i.e.

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
    }
}

Answer 5

you can also use rx bindings by jake wharton to accomplish this. here is a sample that pads 2 seconds between successive clicks:

RxView.clicks(btnSave)
                .throttleFirst(2000, TimeUnit.MILLISECONDS, AndroidSchedulers.mainThread())
                .subscribe(new Consumer<Object>() {
                    @Override
                    public void accept( Object v) throws Exception {
//handle onclick event here
                });

//note: ignore the Object v in this case and i think always.

setEnabled(false) works perfectly for me.

The idea is I write { setEnabled(true); } in the beginning and just make it false on the first click of the button.
