短信操作

一、监听短信的接收

1.注册广播接收器 

        <receiver android:name="SMSReceiver">
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>

 

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;

public class SMSReceiver extends BroadcastReceiver {
    
    public static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
    
    @Override
    public void onReceive(Context context, Intent intent) {
        if (SMS_RECEIVED.equals(intent.getAction())) {
            Bundle bundle = intent.getExtras();
            if (bundle != null) {
                Object[] pdus = (Object[]) bundle.get("pdus");
                final SmsMessage[] messages = new SmsMessage[pdus.length];
                String msg = "";
                for (int i = 0; i < pdus.length; i++) {
                    messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                    msg += messages[i].getMessageBody();
                }
                Toast.makeText(context, msg, Toast.LENGTH_LONG).show();
            }
        }
    }

}

2.添加权限 

<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>

 

 二、读取收件箱中的短信

1.从数据库中读取，URI为"content://sms/inbox" 

import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.widget.TextView;

public class MySMSManager extends Activity {
    
    private TextView textview;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        textview = (TextView) findViewById(R.id.textview);
        readShortMessage();
    }
    
    public void readShortMessage() {
        ContentResolver cr = getContentResolver();
        Cursor cursor = cr.query(Uri.parse("content://sms/inbox"), null, null, null, null);
        String msg = "";
        while(cursor.moveToNext()) {
            int phoneColumn = cursor.getColumnIndex("address");  
            int smsColumn = cursor.getColumnIndex("body");  
            msg += cursor.getString(phoneColumn) + ":" + cursor.getString(smsColumn) + "\n";
        }
        textview.setText(msg);
    }
}

2.添加权限 

<uses-permission android:name="android.permission.READ_SMS"></uses-permission>

 

 附：其它短信的URI和数据库表字段 

String SMS_URI_ALL =  "content://sms/"; 
String SMS_URI_INBOX = "content://sms/inbox";
String SMS_URI_SENT = "content://sms/sent";    
String SMS_URI_DRAFT = "content://sms/draft";     
String SMS_URI_OUTBOX = "content://sms/outbox";    
String SMS_URI_FAILED = "content://sms/failed";     
String SMS_URI_QUEUED = "content://sms/queued";   

 

/*
_id => 短消息序号 如100  
thread_id => 对话的序号 如100  
address => 发件人地址，手机号.如+8613811810000  
person => 发件人，返回一个数字就是联系人列表里的序号，陌生人为null  
date => 日期  long型。如1256539465022  
protocol => 协议 0 SMS_RPOTO, 1 MMS_PROTO   
read => 是否阅读 0未读， 1已读   
status => 状态 -1接收，0 complete, 64 pending, 128 failed   
type => 类型 1是接收到的，2是已发出   
body => 短消息内容   
service_center => 短信服务中心号码编号。如+8613800755500  
*/

 

三、打开发送短信界面

 

        Uri uri = Uri.parse("smsto:13800138000");
        Intent it = new Intent(Intent.ACTION_SENDTO, uri);
        it.putExtra("sms_body", "The SMS text");
        startActivity(it);

 

 

四、发送短信

1.通过SmsManager的sendTextMessage(destinationAddress, scAddress, text, sentIntent, deliveryIntent)方法发送



        String msg ="hello"; 
        String number = "1234565678"; 
        SmsManager sms = SmsManager.getDefault(); 
        PendingIntent pi = PendingIntent.getBroadcast(this,0,new Intent(),0); 
        sms.sendTextMessage(number,null,msg,pi,null);

 

2.添加权限

<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>

 

五、直接向数据库写短信

 

        ContentResolver cr = getContentResolver();
        ContentValues cv = new ContentValues();
        cv.put("address", "13800138000");
        cv.put("body", "hello!");
        cr.insert(Uri.parse("content://sms/inbox"), cv);

 

权限：

<uses-permission android:name="android.permission.WRITE_SMS"></uses-permission>

 

 六、监听短信数据库变化

使用ContentObserver ，观察"content://sms"的变化，调用重写的onChange方法，可以监听到短信记录的变化，这样可以监听发短信，同样也是可以监听收短信的。

import android.database.ContentObserver;
import android.os.Handler;
import android.util.Log;

public class SMSObserver extends ContentObserver {

    public SMSObserver(Handler handler) {
        super(handler);
    }
    
    @Override
    public void onChange(boolean selfChange) {
        Log.i("sms", "sms");
    }

}

 

然后在Acitivty或Service里注册这个观察者

getContentResolver().registerContentObserver(Uri.parse("content://sms"),
                                true, new SMSObserver(new Handler()));
