Answer 1

try this code instead:

....
Dialog alertDialog = new Dialog(SMSServiceListActivity.this);
alertDialog.setContentView(R.layout.customalert);
alertDialog.show();

input = (EditText)alertDialog.findViewById(R.id.txtPhoneNo);
btnVerify = (Button)alertDialog.findViewById(R.id.btnSendSMS);

btnVerify.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(input.getWindowToken(), 0);
        alertDialog.dismiss();
    }
});

....
