CodePudding user response：

if you want to show it only once when the user starts typing then use a bool to do so

boolean is_show = false;
text_send.addTextChangedListener(new TextWatcher() {
            @Override
            public void afterTextChanged(Editable s) {}

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

             
            }

            @Override
            public void onTextChanged(CharSequence s, int start,
                                      int before, int count) {

                if(s.length() != 0) {


                    if(!is_show){
                        is_show = true;
                        YoYo.with(Techniques.SlideInUp)
                            .duration(300)
                            .repeat(0)
                            .
                                    playOn(btn_send);
                      }




                    btn_send.setImageResource(R.drawable.ic_send);

or you asking something else?
