访问联系人并获取电子邮件地址

我有一个用于访问联系人的代码片段。当用户单击该按钮时，联系人列表将打开，用户可以从联系人中选择一个人，并且该人的电子邮件地址应写在编辑文本上。我可以收到用户选择的人发来的电子邮件。但我无法将其设置为编辑文本。

static String email = "";


imgbtnaddfromcontacts.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if (v == imgbtnaddfromcontacts) {
                    try 
                    {
                        Intent intent = new Intent(Intent.ACTION_PICK,
                                ContactsContract.Contacts.CONTENT_URI);
                        startActivityForResult(intent, 1);

                    } catch (Exception e) {
                        e.printStackTrace();
                        Log.e("Error in intent : ", e.toString());
                    }
                }
            }
        });
        kimeTxt.setText(email);
    }

    @Override
    public void onActivityResult(int reqCode, int resultCode, Intent data) {
        super.onActivityResult(reqCode, resultCode, data);

        try {
            if (resultCode == Activity.RESULT_OK) {
                // Get data
                Uri contactData = data.getData();
                // Cursor
                Cursor cur = managedQuery(contactData, null, null, null, null);
                ContentResolver contect_resolver = getContentResolver();

                // List
                if (cur.moveToFirst()) {
                    String id = cur
                            .getString(cur
                                    .getColumnIndexOrThrow(ContactsContract.Contacts._ID));

                    Cursor phoneCur = contect_resolver.query(
                            ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                            null,
                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                                    + " = ?", new String[] { id }, null);

                    Cursor emailCur = contect_resolver.query(
