我通过android SmsManager
发送了5封邮件,需要检查投放订单。订单中发送的SMS是否以相同的顺序发送。如果没有,交货的顺序是什么?
我认为我可以通过BroadcastReceiver
来检查交货但是订单怎么样?

在res / layout文件夹中的main.xml文件中,添加以下代码,以便用户可以输入电话号码以及要发送的消息:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Enter the phone number of recipient"
/>
<EditText
android:id="@+id/txtPhoneNo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Message"
/>
<EditText
android:id="@+id/txtMessage"
android:layout_width="fill_parent"
android:layout_height="150px"
android:gravity="top"
/>
<Button
android:id="@+id/btnSendSMS"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Send SMS"
/>
</LinearLayout>
接下来,在SMS活动中,我们连接Button视图,以便当用户点击它时,我们将检查在使用sendSMS发送消息之前是否输入了收件人的电话号码和消息()函数,我们将很快定义:
import android.app.Activity;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.gsm.SmsManager;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class SMS extends Activity
{
Button btnSendSMS;
EditText txtPhoneNo;
EditText txtMessage;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo);
txtMessage = (EditText) findViewById(R.id.txtMessage);
btnSendSMS.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
String phoneNo = txtPhoneNo.getText().toString();
String message = txtMessage.getText().toString();
if (phoneNo.length()>0 && message.length()>0)
sendSMS(phoneNo, message);
else
Toast.makeText(getBaseContext(),
"Please enter both phone number and message.",
Toast.LENGTH_SHORT).show();
}
});
}
}
sendSMS()函数定义如下:
public class SMS extends Activity
{
//...
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
//...
}
//---sends an SMS message to another device---
private void sendSMS(String phoneNumber, String message)
{
PendingIntent pi = PendingIntent.getActivity(this, 0,
new Intent(this, SMS.class), 0);
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, pi, null);
}
}
要发送SMS消息,请使用SmsManager类。与其他类不同,您不直接实例化此类;相反,您将调用getDefault()静态方法来获取SmsManager对象。 sendTextMessage()方法发送带有PendingIntent的SMS消息。 PendingIntent对象用于标识稍后要调用的目标。例如,在发送消息后,您可以使用PendingIntent对象显示另一个活动。在这种情况下,PendingIntent对象(pi)只是指向同一个活动(SMS.java),因此当发送SMS时,不会发生任何事情。
如果您需要监控SMS消息发送过程的状态,您实际上可以使用两个PendingIntent对象和两个BroadcastReceiver对象,例如
//---sends an SMS message to another device---
private void sendSMS(String phoneNumber, String message)
{
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
new Intent(SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
new Intent(DELIVERED), 0);
//---when the SMS has been sent---
registerReceiver(new BroadcastReceiver(){
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS sent",
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;
}
}
}, new IntentFilter(SENT));
//---when the SMS has been delivered---
registerReceiver(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;
}
}
}, new IntentFilter(DELIVERED));
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
}
除了以编程方式发送SMS消息外,您还可以使用BroadcastReceiver对象拦截传入的SMS消息。
要了解如何从Android应用程序中接收SMS消息,请在AndroidManifest.xml文件中添加该元素,以便SmsReceiver类可以拦截传入的SMS消息:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="net.learn2develop.SMSMessaging"
android:versionCode="1"
android:versionName="1.0.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".SMS"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".SmsReceiver">
<intent-filter>
<action android:name=
"android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
<uses-permission android:name="android.permission.SEND_SMS">
</uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS">
</uses-permission>
</manifest>
在SmsReceiver类中,扩展BroadcastReceiver类并覆盖onReceive()方法:
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.gsm.SmsMessage;
import android.widget.Toast;
public class SmsReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
//---get the SMS message passed in---
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String str = "";
if (bundle != null)
{
//---retrieve the SMS message received---
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i=0; i<msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
str += "SMS from " + msgs[i].getOriginatingAddress();
str += " :";
str += msgs[i].getMessageBody().toString();
str += "n";
}
//---display the new SMS message---
Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
}
}
}
