XML

 <androidx.appcompat.widget.AppCompatAutoCompleteTextView
        android:id="@+id/origin_adrs"
        android:layout_width="match_parent"
        android:layout_height="35dp"
        android:drawableStart="@drawable/ic_baseline_search_24"
        android:layout_marginRight="5dp"
        android:layout_marginLeft="5dp"
        android:paddingLeft="15dp"
        android:paddingRight="15dp"
        android:hint="@string/selectionner_votre_addresse"
        android:fontFamily="@font/nunito_semibold"
        android:textSize="@dimen/standard_text_14"
        android:background="@drawable/backgroud_text_input_adress"
        />

JAVA CODE

Boolean isHere2 = false;
autoCompleteTextView.setOnTouchListener(new View.OnTouchListener() {
        @SuppressLint("ClickableViewAccessibility")
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;
            final int DRAWABLE_TOP = 1;
            final int DRAWABLE_RIGHT = 2;
            final int DRAWABLE_BOTTOM = 3;
            autoCompleteTextView.addTextChangedListener(new TextWatcher() {
                @Override
                public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                    String adress = autoCompleteTextView.getText().toString();
                }

                @Override
                public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                    if(charSequence.length() == 0){
                        autoCompleteTextView.setCompoundDrawablesWithIntrinsicBounds(ContextCompat.getDrawable(getApplicationContext(),R.drawable.ic_baseline_search_24), null, null, null);
                        isHere2 = false;
                    }else{
                        autoCompleteTextView.setCompoundDrawablesWithIntrinsicBounds(ContextCompat.getDrawable(getApplicationContext(),R.drawable.ic_baseline_search_24), null, ContextCompat.getDrawable(getApplicationContext(),R.drawable.ic_baseline_cancel_24), null);
                        isHere2 = true;
                    }
                }

                @Override
                public void afterTextChanged(Editable editable) {

                }
            });

            if(isHere2){
                if (event.getAction() == MotionEvent.ACTION_UP) {
                    if (event.getRawX() >= (autoCompleteTextView.getRight() - autoCompleteTextView.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                        autoCompleteTextView.setText("");
                        isHere2 = false;
                        return true;
                    }
                }
            }
            return false;
        }
    });
