如何从autocompletetextview中删除以前选择的项目

AutoCompleteTextView autoCompleteTextView = findViewById(R.id.autoCompleteTextView);

autoCompleteTextView.addTextChangedListener(new TextWatcher() {
    @Override
    public void afterTextChanged(Editable s) {
        String text = s.toString();
        if (text.isEmpty()) {
            // 执行删除操作，例如清空相关数据
        }
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        // 不需要实现
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        // 不需要实现
    }
});
