Get EditText in a listview outside of Adapter

Question

I have a listview with an EditText in each row. Each EditText has his validation, so, when I click the MenuItem "Finish", I want to make the validation of each EditText and show errors if there were any.

I know how to access my EditText inside my adapter, but inside my adapter, I can't access MenuItem. Outside my adapter, I can access my MenuItem OnClick, but I can't get my edittext values anymore...

Any solution???

You could set a field in your adapter (like `needValidation`) to `true` when the user click on the "Finish" menu. And then call `notifyDataSetChanged()` on your adapter. So you will have access to your views again. Once the validation is done, set `needValidation` to `false` again. — Gaëtan, Dec 16 '14 at 16:04

You can iterate through your listView and do something like:

View v = myList.getAdapter().getView(i, null, null);
EditText et = (EditText) v.findViewById(nameOfTheView);

By using `null` for the `convertView` and `parent` parameters of the `getView(int, View, ViewGroup)` method, you loose the recycling strategy and may end up with the wrong `LayoutParam` for the current view. – Gaëtan Dec 16 '14 at 16:26
I can access the values with that, but I can't display errors with setErrors. Do you know how to modify the view inside the adapter? – Juliatzin Dec 16 '14 at 18:54

I solved using : ListView item set error Android

The solution was to include an ArrayList of errors in the adapter.

Tx for your help!

One thing you could do is setup a class to hold variables:

public class MyVarHolder {
    public EditText myText;
}

Then you use it into your getView method:

mHolder.myText = (EditText) root.findViewById(R.id.my_edit_text);
convertView.setTag(mHolder);

Last step is get the holder into the onClickListener of your list:

onItemClickListener(AdapterView<?> adapterView, View view, int position, long id) {
    MyVarHolder tag = (MyVarHolder)view.getTag();

   String editText = tag.myText.getText().toString();

   ...Do whatever you want...

This is INSIDE my Adapter, I need to access it OUTSIDE, in the activity – Juliatzin Dec 16 '14 at 16:25
`onItemClickListener` will be outside into your `Activity` or `Fragment` – MineConsulting SRL Dec 16 '14 at 16:26
I need to validate throught the menuItem, not the onItemClickListener, otherwise, I could do it in the adapter – Juliatzin Dec 16 '14 at 16:27
What do you mean for `MenuItem`? – MineConsulting SRL Dec 16 '14 at 16:30
A button in the ActionBar – Juliatzin Dec 16 '14 at 16:31
