从Dialog EditText更改TextView

Question

So i have a dialog that shows up in the fragment. i need to change a textview with a dialog. so i created a dialog with an editText, but i am not sure how do i pass the char sequence from dialog to fragment.

rename_dialog_edit is EditText from dialog

GroupName is TextView from fragment

on positive click:

GroupName.setText((CharSequence) rename_dialog_edit);

after positive click my textview gets empty. how do i properly set it?

Update

    protected static TextView GroupName;
protected static EditText rename_dialog_edit;

In the onCreateView i have:

TextView GroupName = (TextView) view.findViewById(R.id.group_details_name); 
EditText rename_dialog_edit = (EditText) view.findViewById(R.id.groupdetails_rename);

here is my onCreateDialog:

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        LayoutInflater inflater = getActivity().getLayoutInflater();
        //int title = getArguments().getInt("title");

        return builder.setView(inflater.inflate(R.layout.group_details_rename_dialog, null))
                //.setIcon(R.drawable.logo)
                //.setTitle(R.string.groupDetails_rename)
                .setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
           @Override
           public void onClick(DialogInterface dialog, int id) {
               doPositiveClick();
           }
                    })
                        .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
                               public void onClick(DialogInterface dialog, int id) {
                                   doNegativeClick();
                               }
                        })
                        .create();
    }

and here is my positive click:

    public static void doPositiveClick() {

    GroupName.setText(rename_dialog_edit.getText().toString());

    //Log.i("FragmentAlertDialog", "Positive click!");
}

Get the Text from the EditText like:

String str= ((EditText)findViewById(R.id.rename_dialog_edit)).getText().toString();

Set it to textView like:

TextView text = (TextView) findViewById(R.id.this_is_the_id_of_your_textview);
text.setText(str);

have you tried something like this?

Update :

Inside the button listener just do:

GroupName.setText(rename_dialog_edit.getText().toString())

Also try to be consistent with of camelCase variable names in Java. It might be a good practice.
