如何在Google Places API请求中添加延迟？

Question

我想通过为每个用户输入增加延迟来减少对Google Places API的请求，但是我不确定如何实现这一点。这通常是我为等待用户输入的EditText添加延迟的方法：

        editTextEmail.addTextChangedListener(new TextWatcher() {
        final Handler handler = new Handler();
        Runnable runnable;

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            isEmailValid = false;
            textInputLayoutEmail.setError(null);
            enableDisableButton();
            handler.removeCallbacks(runnable);
        }

        @Override
        public void afterTextChanged(Editable s) {
            runnable = new Runnable() {
                @Override
                public void run() {
                    callGooglePlacesAPI()
                }
            };
            handler.postDelayed(runnable, 1000);
        }
    });

这是我用来调用Google PLaces API的代码：

    editTextLocation.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus) {
            editTextLocation.setShowSoftInputOnFocus(false);
            searchLocation();
        }
        }
    });


public void searchLocation(){
    try
    {
        editTextLocation.clearFocus();
        //hide soft keyboard
        InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(getView().getWindowToken(), 0);
        Intent intent = new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY)
                .build(getActivity());
        startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);
    }catch (Exception e){
        e.printStackTrace();
    }
}

有没有办法做到这一点？请帮助提供建议。谢谢。
