Ich habe ein Code-Snippet für den Zugriff auf Kontakte. Wenn der Benutzer auf die Schaltfläche klickt, wird die Kontaktliste geöffnet, und der Benutzer kann eine Person aus den Kontakten auswählen. Die E-Mail-Adresse der Person sollte in einen Edittext geschrieben werden. Ich kann die E-Mail von den Personen erhalten, die der Benutzer ausgewählt hat. Aber ich kann es nicht auf den Edittext setzen.

static String email = "";


imgbtnaddfromcontacts.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if (v == imgbtnaddfromcontacts) {
                    try 
                    {

                                ContactsContract.Contacts.CONTENT_URI);
                        startActivityForResult(intent, 1);

                    } catch (Exception e) {
