推荐答案

请问你的code样子？即TextWatcher的正常行为。 例如：

How does your code looks like? that is the normal behaviour of TextWatcher. Example:

myInput.addTextChangedListener(new TextWatcher() {
        boolean mToggle = false;
        public void onTextChanged(CharSequence cs, int s, int b, int c) {
                        }

        public void afterTextChanged(Editable editable) {
                           if (mToggle)  
                              Toast.makeText(getBaseContext(), "HIT KEY", Toast.LENGTH_LONG).show();
                           mToggle = !mToggle;

        }

        public void beforeTextChanged(CharSequence cs, int i, int j, int k) {
        }
    });
