android获取短信并自动填充

package com.velo.quanquan.util;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

import net.iaf.framework.util.Loger;
import android.app.Activity;
import android.database.ContentObserver;

public class SmsContentUtil extends ContentObserver {

  public static final String SMS_URI_INBOX = "content://sms/inbox";

  private Activity activity = null;

  private String smsContent = "";

  private EditText verifyText = null;

  public SmsContentUtil(Handler handler) {
    super(handler);
  }

  public SmsContentUtil(Activity activity, Handler handler, EditText verifyText) {
    super(handler);
    this.activity = activity;
    this.verifyText = verifyText;
  }

  @Override
  public 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 = activity.getContentResolver().query(Uri.parse(SMS_URI_INBOX), new String[] {
      "_id", "address", "body", "read", "date" }, "address=? and read=?",
      new String[] { "15555215554", "0" }, "date desc");

    if (cursor != null) {// 如果短信为未读模式
      cursor.moveToFirst();
      if (cursor.moveToFirst()) {

        String smsbody = cursor
            .getString(cursor.getColumnIndex("body"));
        Loger.e("smsbody:" + smsbody);
        String regEx = "[^0-9]";
        Pattern p = Pattern.compile(regEx);
        Matcher m = p.matcher(smsbody.toString());
        smsContent = m.replaceAll("").trim().toString();
        verifyText.setText(smsContent);
        verifyText.setSelection(verifyText.getText().toString().trim().length());
      }

    }
  }

}

调用该方法的地方的代码：

SmsContentUtil smsContent = new SmsContentUtil(LoginActivity.this, new Handler(), verifyText);

 // 注册短信变化监听
   this.getContentResolver().registerContentObserver(Uri.parse("content://sms/"), true, smsContent );
