5.模拟短信发送

代码实现模拟短信的发送。主要的操作步骤有：

//1.获取短信管理器

SmsManager sm = SmsManager.getDefault();

//2.发送短信

sm.sendTextMessage(phone, null, content, null, null);

模拟的代码如下

public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}public void send(View v){EditText et1 = (EditText) findViewById(R.id.et1);EditText et2 = (EditText) findViewById(R.id.et2);String phOne= et1.getText().toString();String cOntent= et2.getText().toString();//1.获取短信管理器SmsManager sm = SmsManager.getDefault();//2.发送短信//sm.sendTextMessage(phone, null, content, null, null);//短信内容很长的时候分成几个发送ArrayList smss = sm.divideMessage(content);for(String string:smss){sm.sendTextMessage(phone, null, string, null, null);}}
