我如何在不使用任何按钮的情况下发送消息，当用户在 3 秒消息自动发送到所需号码后完成消息时，假设在此处输入接收者号码是我的代码。

public void onActivityResult(int requestCode, int resultCode, Intent data){
    ArrayList<String> matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
     String topResult = matches.get(0);
     EditText editText = (EditText)findViewById(R.id.editTextmessage);
     EditText editText1 = (EditText)findViewById(R.id.toNumber);
     String phoneNo = null;
     String sms = null;
    switch(requestCode){
    case check1:

            editText1.setText(topResult);
            phoneNo=editText1.getText().toString();
                break;
    case check:

            editText.setText(topResult);
             sms=editText.getText().toString();

       break;
    }


    try {
        SmsManager smsManager = SmsManager.getDefault();
        smsManager.sendTextMessage(phoneNo, null, sms, null, null);
        Toast.makeText(getApplicationContext(), "Your Message Sent Successfully",
                Toast.LENGTH_LONG).show();
    } catch (Exception e) {
        Toast.makeText(getApplicationContext(),
                "Sending fail, Please try again!",
                Toast.LENGTH_LONG).show();
        e.printStackTrace();
    }

    super.onActivityResult(requestCode, resultCode, data);


}

当用户完成输入或关闭键盘时，您可以启动计时器，如果计时器达到三秒，则发送消息，如果用户停止计时器（重新打开键盘或键入比您重置计时器更多的内容）到三秒？
