Android中 备份短信 还原短信

备份短信

读取手机里的短信，备份成xml文件保存到SD卡上。

xml文件就只有一个button控件，就不再给出xml代码了。

import java.io.File;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import org.xmlpull.v1.XmlSerializer;import android.app.Activity;import android.content.ContentResolver;import android.database.Cursor;import android.net.Uri;import android.os.Bundle;import android.os.Environment;import android.util.Xml;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.Toast;public class MainActivity extends Activity {private Button bt_readsms;/** * 短信备份的文件对象 */private File smsBackUpFile;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        bt_readsms = (Button) findViewById(R.id.bt_readsms);        bt_readsms.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {try {//创建一个存储备份短信的文件对象smsBackUpFile = new File(Environment.getExternalStorageDirectory(),"sms.xml");//创建一个xml文件的生成器。 XmlSerializer serializer = Xml.newSerializer(); //完成序列化器初始化操作。 FileOutputStream os = new FileOutputStream(smsBackUpFile); serializer.setOutput(os, "utf-8");//内容提供者。//获取到一个数据库的内容的解析者ContentResolver resolver = getContentResolver();//游标（结果集）Cursor cursor = resolver.query(Uri.parse("content://sms"),new String[]{"address","date","type","body"}, null, null,null);//生成xml文件的头serializer.startDocument("utf-8", true);serializer.startTag(null, "smss");while(cursor.moveToNext()){serializer.startTag(null, "sms");String address = cursor.getString(0);String date = cursor.getString(1);String type = cursor.getString(2);String body = cursor.getString(3);serializer.startTag(null, "address");System.out.println("短信地址："+address);serializer.text(address);serializer.endTag(null, "address");serializer.startTag(null, "date");System.out.println("短信时间："+date);serializer.text(date);serializer.endTag(null, "date");serializer.startTag(null, "body");System.out.println("短信内容："+body);serializer.text(body);serializer.endTag(null, "body");serializer.startTag(null, "type");System.out.println("短信类型："+type);serializer.text(type);serializer.endTag(null, "type");serializer.endTag(null, "sms");}cursor.close();serializer.endTag(null, "smss");serializer.endDocument();os.close();Toast.makeText(getApplicationContext(), "备份完成", 1).show();} catch (Exception e) {e.printStackTrace();}}});    }   }

还原短信

通过代码程序控制向手机发送短信，10s后手机可以接收到短信

xml文件就只有一个button控件，就不再给出xml代码了。

import android.app.Activity;import android.content.ContentResolver;import android.content.ContentValues;import android.net.Uri;import android.os.Bundle;import android.view.View;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}/** * 还原一条短信 *  * @param view */public void click(View view) {new Thread(){public void run() {try {//等待10秒钟的时间Thread.sleep(10000);} catch (InterruptedException e) {e.printStackTrace();}// 获取到一个数据库的内容的解析者ContentResolver resolver = getContentResolver();ContentValues values = new ContentValues();values.put("address", "95533");//指定短信的发件人values.put("date", System.currentTimeMillis());values.put("body", "尊敬的客户,您的银行卡余额还有300万");values.put("type", "1");resolver.insert(Uri.parse("content://sms"), values);};}.start();}}
