Question

我的项目是关于将安装应用程序的2部手机之间的通信。通信是SMS通信，每个SMS包含数据，接收设备必须解释它并在指定的ListView中排序该项目包含以下类：发送数据表和显示接收数据的3个ListView类。

我的问题是，我不确定我的短信是否已发送（因为单击发送按钮后没有出现对话框窗口。此外，在第二个模拟器上没有只要有传入的短信，就会显示。

发送数据表：

import android.app.Activity;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

public class AddContactDeatils extends Activity implements OnClickListener {
Button sendToParallel, sendToParallel2;
TextView nameT, idT, phoneT;
EditText nameF, idF, phoneF;
int recipient;




@Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
return super.onCreateOptionsMenu(menu);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.add_contact_form);
sendToParallel=(Button)findViewById(R.id.sendToParallel);
sendToParallel.setOnClickListener(this);
sendToParallel2=(Button)findViewById(R.id.sendToParallel2);
sendToParallel2.setOnClickListener(this);
nameT=(TextView)findViewById(R.id.nameTitle);
idT=(TextView)findViewById(R.id.idTitle);
phoneT=(TextView)findViewById(R.id.phoneTitle);
nameF=(EditText)findViewById(R.id.nameField);
idF=(EditText)findViewById(R.id.idField);
phoneF=(EditText)findViewById(R.id.phoneField);


    }
    protected void sendSms(String phoneNumber, String message) {
// TODO Auto-generated method stub
SmsManager sms=SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, null, null);
    }

    public void checkRecipient(EditText et)
    {
try {
    recipient=Integer.parseInt(et.toString());
} catch (Exception e) {
    // TODO: handle exception
    Toast.makeText(this, "Only numbers are allowed", Toast.LENGTH_LONG).show();
    et.setText("");
}
    }

    @Override
    public void onClick(View v) {
// TODO Auto-generated method stub
int id=v.getId();

 String message = null;
 String name=nameF.toString();
 message+=name+";";
 String idTxt=idF.toString();
 message+=idTxt+";";
 String phone=phoneF.toString();
 message+=phone;

switch(id)
{
case R.id.sendToParallel:
{

    sendSms("5554", message) ; 


    break;
}
case R.id.sendToParallel2:
{
    sendSms("5556", message) ; 
    break;
}
}

    }

        }

添加发送和接收短信的权限

   <uses-permission android:name="android.permission.SEND_SMS" >
</uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS" >
</uses-permission>
<uses-permission android:name="android.permission.READ_SMS" >
</uses-permission>

和Run Two Emulator for Send Sms ..例如5554到5556

无法在2个仿真器之间发送SMS
