随着Android版本的不断更新，在4.0以上使用广播接收器已经监听不到短信了
还是使用ContentObserver来监听
SmsContentObserver:
package observer;import java.util.regex.Matcher;import java.util.regex.Pattern;import android.content.Context;import android.database.ContentObserver;import android.database.Cursor;import android.net.Uri;import android.os.Handler;import android.os.Message;import android.support.v4.content.CursorLoader;import android.util.Log;public class SmsContentObserver extends ContentObserver {/**收到短信时Message的what值*/public static final int MESSAGE_WHAT_SMS_RECEIVED = 0x01;/**SMS收件箱的URI*/public static final String SMS_URI_INBOX = "content://sms/inbox";private Context context = null;private Handler handler;public SmsContentObserver(Context context, Handler handler) {super(handler);this.context = context;this.handler = handler;}@Overridepublic void onChange(boolean selfChange) {super.onChange(selfChange);Cursor cursor = null;// 光标// 读取收件箱中指定号码的短信// cursor = context.managedQuery(Uri.parse(SMS_URI_INBOX), new String[]// {// "_id", "address", "body", "read" }, "address=? and read=?",// new String[] { "10086", "0" }, "date desc");//read=0 未读短信CursorLoader loader = new CursorLoader(context,Uri.parse(SMS_URI_INBOX), new String[] {"_id", "address", "body", "read" }, "read=?",new String[]{"0"}, "date desc");cursor = loader.loadInBackground();if (cursor != null) {// 如果短信为未读模式cursor.moveToFirst();if (cursor.moveToFirst()) {String smsbody = cursor.getString(cursor.getColumnIndex("body"));Log.i("info","短信内容：" + smsbody);String regEx = "[^0-9]";Pattern p = Pattern.compile(regEx);Matcher m = p.matcher(smsbody.toString());String smsContent = m.replaceAll("").trim().toString();Message msg = Message.obtain();msg.obj = smsContent;msg.what = MESSAGE_WHAT_SMS_RECEIVED;handler.sendMessage(msg);}}}}使用方法-在需要的地方添加如下代码：
Handler handler = new Handler(){@Overridepublic void handleMessage(Message msg) {switch (msg.what) {case SmsContentObserver.MESSAGE_WHAT_SMS_RECEIVED:String smsContent = msg.obj.toString();textView.setText(smsContent);break;default:break;}}};SmsContentObserver content = new SmsContentObserver(this, handler);// 注册短信变化监听this.getContentResolver().registerContentObserver(Uri.parse(SmsContentObserver.SMS_URI_INBOX), true, content);更多相关文章
