从ListView中的EditText获取更新的值

Question

I have a DialogFragment in which there is ListView, each ListItem has three TextViews and one EdiText, EditText allows integer values which can be changed as per the user requirement. So onClick of positive button of dialog I want to send thoes updated Integer value to the server. While fetching EditText's text it fetches the old values not the updated one.

The code I have written

 View v;

    ArrayList<String> edValues = new ArrayList<String>();

    EditText et;

                            for (int i = 0; i < alObj.size(); i++) {
                                v = adapter.getView(i, null, null);
                                et = (EditText) v.findViewById(R.id.user_bill_edit);

//Dialog

public class CaseUserList extends DialogFragment  {


    private Context context;
    private String pipeSeparatedUserLists;
    Boolean isOperationEdit = false;
    String strCaseId = null;
    private UserBillRateAdapter adapter;
    ArrayList<Object> alObj;

    public Dialog onCreateDialog(Bundle savedInstanceState) {

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

        context = getActivity();
        strCaseId = getArguments().getString(CaseConstants.TABLE_CASE_LIST_CASE_ID);
        //isOperationEdit = getArguments().getBoolean("isEdit");

        //Send network request to get the list
        new userBillRateList().executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);

        //Prepare the list layout
        View view = getActivity().getLayoutInflater().inflate(R.layout.layout_case_user_list, null);
        builder .setView(view)
                .setPositiveButton("Update", new Dialog.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int id) {
                        View v;
                        ArrayList<String> edValues = new ArrayList<String>();
                        EditText et;

                        for (int i = 0; i < alObj.size(); i++) {
                            v = adapter.getView(i, null, null);
                            et = (EditText) v.findViewById(R.id.user_bill_edit);
                            edValues.add(et.getText().toString());
                        }
                    }
                })

                .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        CaseUserList.this.getDialog().cancel();
                    }
                });
        return builder.create();
    }

Answer 1

Try to replace adapter.getView(i) with yourListView.getChildAt(i) .
I suppose it will help.

Answer 2

In your adapter add text change listener like

EditText searchTo = (EditText)findViewById(R.id.medittext);
searchTo.addTextChangedListener(new TextWatcher() {

    @Override
    public void afterTextChanged(Editable s) {
        // TODO Auto-generated method stub

    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        // TODO Auto-generated method stub

    }

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

        //store value in your POJO class
        // like getItem(position).setUserEnterValue(s.toString());
    } 

});

on positive button click get value from adapter like

 for (int i = 0; i < alObj.size(); i++) {
   edValues.add(list.getAdapter().getItem(i).getUserEnterValue());
 }
