用户确认输入后,如何运行方法?

如果您试图添加搜索功能,为什么不使用搜索视图。

有很多选择,我在下面写3个选择。

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

例子:

    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
        }
}
