短信,电话拦截

短信

public class SMSIntercept extends BroadcastReceiver {
 private final String PDUS = "pdus";

 @Override
 public void onReceive(Context context, Intent intent) {
  Bundle bundle = intent.getExtras();
  if (bundle != null) {
   // 获取收到的短息数据
   Object[] objArray = (Object[]) bundle.get(PDUS);
   // 定义封装短信内容的SmsMessage对象的数组
   SmsMessage[] messages = new SmsMessage[objArray.length];
   // 循环处理收到的所有短信内容
   for (int i = 0; i < objArray.length; i++) {
    // 将每条短信数据转化成SmsMessage对象
    messages[i] = SmsMessage.createFromPdu((byte[]) objArray[i]);
    // 获取发送短信的手机号码
    String telPhoneNum = messages[i].getOriginatingAddress();
    // 短信内容
    String displayMessageBody = messages[i].getDisplayMessageBody();
    Hashtable<String, String> messageInterceptHT = DataCache.getInstance().getMessageInterceptHT();
    // messageInterceptHT中含有被屏蔽号码,则停止广播继续传递,进行短信拦截
    if (messageInterceptHT.containsKey(telPhoneNum)) {
