Android读取系统短信（短信窃听器）

1、清单文件AndroidManifest.xml需要获取短信的权限

2、MainActivity.java中通过内容解析器（ContentResolver）读取系统短信

package com.t20.sms;

import java.text.SimpleDateFormat;
import java.util.Date;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.ContentResolver;
import android.database.Cursor;
import android.view.View;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
	}
	/**
	 * 获取系统短信
	 * @param v
	 */
	public void sms(View v){
		//获取内容解析器（ContentResolver）
		ContentResolver resolver= getContentResolver();
		//定义一个URI（Uniform Resource Identifier 统一资源标示符）
		//查全部短信
		Uri uri=Uri.parse("content://sms/");
		Cursor cursor=resolver.query(uri, null, null, null, null);
		//输出集合内容
		AlertDialog.Builder dialog=new AlertDialog.Builder(MainActivity.this);
		dialog.setTitle("短信列表：");
		StringBuilder sb=new StringBuilder();
		int i=0;		
		while (cursor.moveToNext()) {
			String address=cursor.getString(cursor.getColumnIndex("address"));
			String body=cursor.getString(cursor.getColumnIndex("body"));
			String dateString=cursor.getString(cursor.getColumnIndex("date"));
			Long dateLong=Long.parseLong(dateString);
			SimpleDateFormat sdf=new SimpleDateFormat("yyy-MM-dd hh:mm:ss");
			Date date=new Date(dateLong);
			String dateShow=sdf.format(date);
			if(i!=0){
				sb.append("\n");
			}
			sb.append("号码："+address+" 内容："+body+" 时间："+dateShow);			
			i++;
		}
		cursor.close();
		dialog.setMessage(sb);
		dialog.show();
	}

}
