Question

在我的应用中，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将短信发送给联系人（或电子邮件或其他内容）。

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();
                            }

意图部分用于发送电子邮件 - 它向用户显示可从客户端中选择的列表，这就是我想要的。您会看到联系人姓名和电话号码有两个变量。用户点击列表名称，然后点击发送短信，弹出列表似乎从短信，电子邮件，蓝牙等选择。我从弹出列表中选择短信或任何其他已安装的短信应用程序，客户端出现与字段（to，text）为空。我希望数字出现在短信表格的短信框中。因此，如果用户点击“Tom Jones”然后点击“发送短信”，Tom Jones的数字应该已经填入客户端。我的代码没有这样做。

我也尝试使用这些行发送短信，但他们导致强制关闭：

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，使用此代码会随机崩溃我的应用程序（不知道原因）

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，如果文字太长，邮件就不会消失。您必须根据编码尊重最大长度。更多信息SMS Manager在少于160个字符时发送mutlipart消息。
