How do I run a method once a user has confirmed their input?

Question

Im making a program where a user has to search through some of my data.

I've created an edit view for the user to put their text in to, but I want to run a method once the user has confirmed their input.

How do I do this?

Thank you.

Do you have a confirm button? If yes, then use its `onClickListener`... — deHaar, Jul 02 '18 at 10:13
set OnClickListener on confirm-button and editText.getText().toString() once clickListener onClick is called — JacksOnF1re, Jul 02 '18 at 10:13
@deHaar I want to use the confirm button on the users keyboard. — Joshua Best, Jul 02 '18 at 10:14
@AdriaanKoster There isn't any code. This is the start of my activity. — Joshua Best, Jul 02 '18 at 10:15

If you are trying to add a search feature , why not use a search view instead.

there are many options to do this, i am writing 3 options below.

1 - If you have confirm button then use its onclicklistener for you method call.

2 - If you don't have confirm button then add focusChangeListener in edittext and call you method when edittext focus is lost.

3 - You can use a timerTask like when user stopped typing for 2 second (we assume that user input is done) you can call your method

Example:

    edt_search.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // user is typing: reset already started timer (if existing)
            if (timer != null) {
                timer.cancel();
            }
        }
        @Override
        public void afterTextChanged(final Editable s) {
            timer = new Timer();
            timer.schedule(new TimerTask() {
                @Override
                public void run() {

                    // Search Logic
                       if (!s.toString().trim().isEmpty())
                       // Your Function call
                }
            }, 500); // 350ms delay before the timer executes the "run“ method from TimerTask
        }
}
