Android监听短信到来并自动填充到输入框中

基本原理：通过ContentObserver观察者监听sms数据库的改变，当有变化时检测是否是来自指定号码的短信，如果是的话就通过正则表达式获得需要的内容，然后贴代码 (*^__^*) 嘻嘻……：

 1 /**
 2  *
 3 * @ClassName: SmsContent
 4 * @Description: 短信监听类
 5 * @author guoyizhe
 6 * @email [email protected]
 7 * @date 2015-6-9 下午3:30:12

10 public class SmsContent extends ContentObserver {
11
12     public static final String SMS_URI_INBOX = "content://sms/inbox";
13     private Activity activity = null;
14     private String smsContent = "";
15     private EditText verifyText = null;
16     private Handler handler;
17     private int SMS_CONTENT = 1;
18
19     public SmsContent(Activity activity, Handler handler, EditText verifyText) {
20         super(handler);
21         this.activity = activity;
22         this.verifyText = verifyText;
23         this.handler = handler;
24     }
25
26     @Override
27     public void onChange(boolean selfChange) {
28         super.onChange(selfChange);
29         Cursor cursor = null;
30         // 读取收件箱中指定号码的未读短信,一般只监听自己公司使用的短信通道号码，如果有多个，查询语句改为 address in (xxx，xxx)就可以了
31         cursor = activity.getContentResolver().query(Uri.parse(SMS_URI_INBOX), new String[] { "_id", "address", "body", "read" }, "address =？ and read=?",
32                 new String[] { "5554" ,"0" }, "date desc");
33         if (cursor != null) {//有未读短信
34             cursor.moveToFirst();
35             if (cursor.moveToFirst()) {//这里也是针对一条，多条的话使用while循环遍历出即可
36                 String smsbody = cursor.getString(cursor.getColumnIndex("body"));
37                 String regEx = "[^0-9]";
38                 Pattern p = Pattern.compile(regEx);
39                 Matcher m = p.matcher(smsbody.toString());
40                 smsContent = m.replaceAll("").trim().toString();
41                 verifyText.setText(smsContent);
42             }
43             //通过handler可以处理许多其他的事务，这里只是举个栗子
44             handler.obtainMessage(SMS_CONTENT, verifyText.getText().toString()).sendToTarget();
45             cursor.close();
46         }
47     }
48 }

然后是主Activity：

 1 /**
 2  *
 3 * @ClassName: MainActivity
 4 * @Description: 监听到来的短信并自动填充，也可以处理一些事件
 5 * @author guoyizhe
 6 * @email [email protected]
 7 * @date 2015-6-9 下午2:17:56

10 public class MainActivity extends Activity {
11     private Handler handler = new Handler(){
12         public void handleMessage(android.os.Message msg) {
13             switch(msg.what){
14             case 1://处理短信到来后事件
15                 //TODO
16                 break;
17             }
18         };
19     };
20
21     @Override
22     protected void onCreate(Bundle savedInstanceState) {
23         super.onCreate(savedInstanceState);
24         setContentView(R.layout.activity_main);
25         EditText text = (EditText) findViewById(R.id.smsObserver);
26         SmsContent content = new SmsContent(MainActivity.this, handler, text);
27         // 注册短信变化监听
28         this.getContentResolver().registerContentObserver(Uri.parse("content://sms/"), true, content);
29     }
30 }
