Android 使用 ArrayList 向多个联系人发送短信 [英] Android send SMS to multiple contacts using ArrayList

问题描述

我正在编写一个向多个联系人发送短信的应用.联系人号码存储在 ArrayList(从另一个活动接收)中.我无法使用此 ArrayList 将多个联系人传递给内置的 SMS android 应用程序.这是代码:

Im writing an app that sends an SMS to several contacts. The contacts numbers are stored in an ArrayList (was received from another activity). I am not able to use this ArrayList to pass several contacts to the built-in SMS android app. This is the code:

ArrayList<String> numbersArrayList=getIntent().getExtras().getStringArrayList("phoneNumbers");
String message= "this is a custom message";
Intent smsIntent = new Intent(Intent.ACTION_VIEW);
smsIntent.putExtra("sms_body", message); 
smsIntent.putExtra("address", ??????????);
smsIntent.setType("vnd.android-dir/mms-sms");
startActivity(smsIntent);

我可以通过简单的for each"循环和覆盖 toString 方法迭代这些联系人并将其打印到 LogCat.

I can iterate and print these contacts to the LogCat the simple "for each" loop and overriding toString method.

推荐答案

使用此代码..

String toNumbers = "";
for ( String s : numbersArrayList)  
{  
    toNumbers = toNumbers + s + ";"
}  
toNumbers = toNumbers.subString(0, toNumbers.length - 1);
String message= "this is a custom message";

Uri sendSmsTo = Uri.parse("smsto:" + toNumbers);
                Intent intent = new Intent(
                        android.content.Intent.ACTION_SENDTO, sendSmsTo);
                intent.putExtra("sms_body", message);
                startActivity(intent);
