Android实战教程第四篇之简单实现短信发送器

package com.ydl.smssender; 
 
import java.util.ArrayList; 
 
//省略导包 
 
public class MainActivity extends Activity { 
 
 @Override 
 protected void onCreate(Bundle savedInstanceState) { 
 super.onCreate(savedInstanceState); 
 setContentView(R.layout.activity_main); 
 } 
 
 
 public void send(View v){ 
 //拿到用户输入的号码和内容 
 EditText et_phOne= (EditText) findViewById(R.id.et_phone); 
 EditText et_cOntent= (EditText) findViewById(R.id.et_content); 
  
 String phOne= et_phone.getText().toString(); 
 String cOntent= et_content.getText().toString(); 
  
 //1.获取短信管理器 
 SmsManager sm = SmsManager.getDefault(); 
  
 //2.切割短信，把长短信分成若干个小短信 
 ArrayList smss = sm.divideMessage(content);//an ArrayList of strings that, in order, comprise the original message 
  
 //3.for循环把集合中所有短信全部发出去 
 for (String string : smss) { 
  
  sm.sendTextMessage(phone, null, string, null, null);//Send a text based SMS. 
 } 
 } 
 
}
