如果手机IN_SERVICE产生吐司手机服务，如果它不是那么产生吐司手机不在服务区
 我尝试这个code

 公共类MyphoneStateListener扩展PhoneStateListener
{
公共无效onCallStateChanged（INT状态，弦乐incomingNumber）
{
     开关（州）{
        案例TelephonyManager.CALL_STATE_IDLE：
            打破;
        案例TelephonyManager.CALL_STATE_RINGING：
           发电子邮件（）;
            打破;
        案例TelephonyManager.CALL_STATE_OFFHOOK：
        默认：
            打破;
        }
        super.onCallStateChanged（州，incomingNumber）;
    }
}

telMng.listen（新PhoneStateListener（）{

解决方案

TelephonyManager telMng = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);    
telMng.listen(new PhoneStateListener() {    
    @Override
    public void onServiceStateChanged (ServiceState serviceState) {
        super.onServiceStateChanged(serviceState);
        String phonestate;

        switch(serviceState.getState()) {
            case ServiceState.STATE_EMERGENCY_ONLY: 
                phonestate ="STATE_EMERGENCY_ONLY";
                break;
            case ServiceState.STATE_IN_SERVICE: 
                phonestate ="STATE_IN_SERVICE";
                break;
            case ServiceState.STATE_OUT_OF_SERVICE: 
                phonestate ="STATE_OUT_OF_SERVICE"; 
                break;
            case ServiceState.STATE_POWER_OFF: 
                phonestate ="STATE_POWER_OFF"; 
                break;
            default:
                phonestate = "Unknown";
                break;
        }   
    } 
}, PhoneStateListener.LISTEN_SERVICE_STATE);
