使用ContentObserve监听用户发出的短信

import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.app.Activity;
import android.database.ContentObserver;
import android.database.Cursor;
import android.view.Menu;

public class MinitorSms extends Activity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_minitor_sms);
    //为content://sms的数据改变注册监听器
    getContentResolver().registerContentObserver(Uri.parse("content://sms"),
          true, new SmsObserver(new Handler()));
  }
  //提供自定义的ContentObserver监听器类
  private final class SmsObserver extends ContentObserver{

    public SmsObserver(Handler handler) {
      super(handler);
    }
    public void onChange(boolean selfChange){
      //查询发送箱中的短信(处于正在发送状态的短信放在发送箱)
      Cursor cursor = getContentResolver()
          .query(Uri.parse("content://sms/outbox"),
          null, null, null, null);
      //遍历查询得到的结果集,即可获取用户正在发送的短信
      while(cursor.moveToNext()){
        StringBuilder sb = new StringBuilder();
        //获取短信的发送地址
        sb.append("address=").append(cursor.getString(cursor.getColumnIndex("address")));
        //获取短信的标题
        sb.append(";subject=").append(cursor.getString(cursor.getColumnIndex("subject")));
        //获取短信的内容
        sb.append(";body=").append(cursor.getString(cursor.getColumnIndex("body")));
        //获取短信的发送时间
        sb.append(";time=").append(cursor.getLong(cursor.getColumnIndex("date")));
        System.out.println("Has Sent SMS:::"+sb.toString());
      }
    }

  }

}
