Android发送短信

Question

在我的应用程序中，有包含手机通讯录的列表。当用户点击联系人时，他可以从菜单中选择发送短信给联系人（或电子邮件或其他东西）。

Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 
        while(people.moveToNext()) { 
         int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME); 
         String contact = people.getString(nameFieldColumnIndex); 
         int numberFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER); 
         String number = people.getString(numberFieldColumnIndex); 
         if (contact.equals(myArr2_cs[item])) 
          { 
          Intent int_sms = new Intent(Intent.ACTION_SEND); 
          int_sms.setType("text/plain"); 
          int_sms.putExtra(Intent.EXTRA_EMAIL , new String[]{number}); 
          int_sms.putExtra(Intent.EXTRA_SUBJECT, ""); 
          int_sms.putExtra(Intent.EXTRA_TEXT, ""); 
          try { 
           startActivity(Intent.createChooser(int_sms, "Sending SMS..")); 
          } catch (android.content.ActivityNotFoundException ex) { 
           Toast.makeText(MainActivity.this, "No installed sms clients found", Toast.LENGTH_SHORT).show(); 
          } 

的目的部分是专为发送电子邮件 - 它显示用户清单由客户选择，这是我想要的。 您会看到联系人名称和电话号码有两个变量。 用户点击列表中的名称，然后点击发送短信，弹出列表出现可以选择短信，电子邮件，蓝牙等。我选择从短信列表中选择短信或任何其他安装的短信应用程序，客户端出现字段（to，text）为空。我希望号码出现在短信窗体的短信框中。因此，如果用户点击“汤姆琼斯”，然后点击“发送短信”，汤姆琼斯的号码应该已经填写在客户端。我的代码不这样做。

我也试图与这些线路发送短信，但他们造成了强制关闭：

SmsManager sm = SmsManager.getDefault(); 
String number2 = "6508570720";//this should the number variable 
sm.sendTextMessage(number2, null, "Test SMS Message", null, null); 

OR

Intent sendIntent= new Intent(Intent.ACTION_VIEW); 
sendIntent.putExtra("sms_body", "smsBody"); 
sendIntent.putExtra("address", number); 
sendIntent.setType("vnd.android-dir/mms-sms"); 
startActivity(sendIntent); 

Answer 1

我注意到，使用此代码随机崩溃我的应用程序（唐”知道肯定的原因）

sm.sendTextMessage(number2, null, "Test SMS Message", null, null); 

相反，如果我这样做，它永远不会崩溃：

PendingIntent sent = PendingIntent.getBroadcast(context, 0, new Intent(), 0); 
PendingIntent delivered = PendingIntent.getBroadcast(context, 0, new Intent(), 0); 
sm.sendTextMessage(number2, null, "Test SMS Message", sent, delivered); 

Answer 2

要完成答案，如果文本太长，消息不会消失。您必须考虑编码的最大长度。更多信息此处短信管理器在少于160个字符时发送mutlipart消息。

我，如果你想

//到处使用

SMSUtils.sendSMS(context, phoneNumber, message); 

完全SMSMethod //清单
