用Java从我的Android手机发送短信，我该怎么做呢？

我使这个应用程序从我的手机发送了一些短信，但是如何将其更改为一次发送一条？

我正在尝试发送一条短信并等待回复代码在发送下一封回复之前回复：

Answer 1

查看this类中的sendSms（）方法。

当您致电sendTextMessage()时，您可以传递“已发送”和“已发送”的意图。将这些意图定位回您自己的应用程序。您可以在发送或发送短信时进行回叫。

如果查看与参考源文件相同的项目中的AndroidManifest.xml文件，可以看到定义了两个注册“sms_sent”（和“sms_received”）意图的接收器。如果你看一下我提到的方法，你可以看到在调用sendTextMessage()之前，它会创建两个意图，其中包含动作“sms_sent”和“sms_delivered”。这是您在发送短信时收到通知的方式。

Answer 2

这是一个让您朝着正确的方向前进的一般提示。当你想要以某种异步方式处理项目队列时，一种方法是使用回调/事件处理程序/ call-it-what-you来触发队列中下一个元素的处理。

设置您的消息队列
有一种方法，例如'sendNextMessage'将最顶层的消息从队列中弹出并发送给它
现在，在你的onReceive方法中，你可以调用你的sendNextMessage来触发发送队列中的下一个

对于这种工作方式，您需要确保无论成功与否，都能保证能够获得某种回调。

Answer 3

首先，首先有四到五个步骤

步骤1打开按钮单击或任何触发器启动短信发送

步骤2创建Pending Intent，使用intent对象和OFCOURSE WITH MULTIPLE PENDING INTENT ...播放多个短信发送功能......

步骤3注册的广播接收器将收到未决意图

步骤4根据结果和收到的INTENT，I REPEAT THE INTENT对象你发送下一条消息......这里是代码

我相信它足够可读......保持真棒

public class SMSDoer extends Activity {
 String SENT = "SMS_SENT";
 String DELIVERED = "SMS_DELIVERED";
 PendingIntent sentPI, deliveredPI;
 BroadcastReceiver smsSentReceiver, smsDeliveredReceiver;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

}

@Override
public void onResume() {
super.onResume();
//---create the BroadcastReceiver when the SMS is sent---
smsSentReceiver = new BroadcastReceiver(){
@Override
public void onReceive(Context arg0, Intent intent) {
switch (getResultCode())
{
 case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), “SMS Gone With the wind”,
//db.query update database for recurrisive message calling 
//using intent object for specific message
sendSMS(“db.phoneNumber", "db.msg");

Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(), “Generic failure”,
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(getBaseContext(), “No service”,
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(), “Null PDU”,
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(), “Radio off”,
Toast.LENGTH_SHORT).show();
break;
}
}
};



//---create the BroadcastReceiver when the SMS is delivered---
smsDeliveredReceiver = new BroadcastReceiver(){
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), “SMS delivered”,
Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(), “SMS not delivered”,
Toast.LENGTH_SHORT).show();
break;
}
}
};
//---register the two BroadcastReceivers---
registerReceiver(smsDeliveredReceiver, new IntentFilter(DELIVERED));
registerReceiver(smsSentReceiver, new IntentFilter(SENT));
}

@Override
public void onPause() {
super.onPause();
//---unregister the two BroadcastReceivers---
unregisterReceiver(smsSentReceiver);
unregisterReceiver(smsDeliveredReceiver);
}
public void SmsMaker(View v) {
//query database
sendSMS(“db.phoneNumber", "db.msg", db.row);
}
//---sends an SMS message to another device---
private void sendSMS(String phoneNumber, String message, int rowId)
{
//create multiple Pending intent
sentPI = PendingIntent.getBroadcast(this,rowId, new Intent(SENT), 0);
deliveredPI = PendingIntent.getBroadcast(this, 0, new Intent(DELIVERED), 0);

SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, "+29170000017", message,  sentPI,deliveredPI);
}
}

用Java从我的Android手机发送短信，我怎么能一次做一个？
