Question

我正在创建一个列表，其中每个列表项都有3个小部件，即2个EditText和1个Spinner。我有一个添加按钮，可以在列表中添加新视图。

我创建了两个视图，一个是带有所有带有十字按钮的3个小部件的标题视图，和带有带有添加按钮的所有3个小部件的页脚视图。

最初显示我的页脚视图。当我在该页脚视图的所有3个小部件上输入值时，我想将这些值添加到模型中而不单击它。现在，当我单击“添加”按钮时，它可以正常工作，但是当所有值都填满时，我想添加它而不单击“添加”按钮。

请帮助。

if (holder instanceof FooterViewHolder) {
    final FooterViewHolder footerHolder = (FooterViewHolder) holder;

    unitlist = new ArrayList<>();
   // unitlist.add(0, "Select");
    unitlist.add(0, "unit");
    unitlist.add(1, "gram");

    spinnerAdapter = new ArrayAdapter<String>(activity, R.layout.spinner, unitlist) {

尝试将侦听器添加到每个编辑文本中，并且每当检测到输入更改时，检查所有输入是否都为空，然后添加到列表中

                footerHolder.etAmount.addTextChangedListener(new TextWatcher() {
                    public void afterTextChanged(Editable s) {
                        if (s.toString() != ""){
                            if (footerHolder.etIngredientName.getText().length() != 0) {
                                //Add item to your list
                            }
                        }

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

                        public void onTextChanged(CharSequence s, int start, int before, int count) {}
                    });
                footerHolder.etIngredientName.addTextChangedListener(new TextWatcher() {

                        public void afterTextChanged(Editable s) {
                            if (s.toString() != ""){
                                if (footerHolder.etAmount.getText().length() != 0) {
                                    //Add item to your list
                                }
                            }

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

                            public void onTextChanged(CharSequence s, int start, int before, int count) {}
                        });
