Android收发短信

效果：点击发送短信开始发送短信

收到短信时将短信的内容显示出来

代码如下：

一、权限声明

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

读写，系统的短信库存在data/data/com.android.providers.telephony/databases/mmssms.db  但真机不可读

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

二、代码实现

我们的短信功能用到了SmsManager和SmsMessage两个主要类。

当收不到短信时候，手动在应用管理中将应用的短信收发权限打开　　

//Java
/**
 * Created by Linda on 16/5/14.
 * 短信的收发
 * 根绝国际标准 每条短信的长度不超过160 个字符
 * 如果短信长度过长，可以调用sendMultipartTextMessage()分隔成多条短信来发送
 */
public class MesaageActivity extends Activity {
    private TextView sender;
    private TextView content;
    private EditText to;//接收短信的手机号码
    private EditText msgInput;//发送信息的内容  

    private Button send;  

    private IntentFilter receiveFilter;//短信接收  

    private MessageReceiver messageReceiver;  

    private IntentFilter sendFilter;//短信发送  

    private SendStatusReceiver sendStatusReceiver;  

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.message);
        sender = (TextView) findViewById(R.id.sender);
        content = (TextView) findViewById(R.id.content);
        to = (EditText) findViewById(R.id.to);
        msgInput = (EditText) findViewById(R.id.msg_input);
        send = (Button) findViewById(R.id.send);
//        注册短信接收的广播
        receiveFilter = new IntentFilter();
        receiveFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
        receiveFilter.setPriority(100);
        messageReceiver = new MessageReceiver();
        registerReceiver(messageReceiver, receiveFilter);
//       注册监听短信发送的广播
        sendFilter = new IntentFilter();
        sendFilter.addAction("SENT_SMS_ACTION");
        sendStatusReceiver = new SendStatusReceiver();
        registerReceiver(sendStatusReceiver, sendFilter);
//       点击按钮发送短信
        send.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                SmsManager smsManager = SmsManager.getDefault();
                Intent sentIntent = new Intent("SENT_SMS_ACTION");
                PendingIntent pi = PendingIntent.getBroadcast(
                        MesaageActivity.this, 0, sentIntent, 0);
                //根据号码和内容发送短信（需要权限）
                smsManager.sendTextMessage(to.getText().toString(), null,
                        msgInput.getText().toString(), pi, null);
            }
        });
    }  

    @Override
    protected void onDestroy() {
        super.onDestroy();
        unregisterReceiver(messageReceiver);
        unregisterReceiver(sendStatusReceiver);
    }
//短信接收的广播
    class MessageReceiver extends BroadcastReceiver {  

        @Override
        public void onReceive(Context context, Intent intent) {
            Bundle bundle = intent.getExtras();
            Object[] pdus = (Object[]) bundle.get("pdus");//获取短信数组
            SmsMessage[] messages = new SmsMessage[pdus.length];
            for (int i = 0; i < messages.length; i++) {
                messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);//将pdu字符数组转换成SmsMessage对象
            }
            String address = messages[0].getOriginatingAddress();//获取短信发送方的号码
            String fullMessage = "";
            for (SmsMessage message : messages) {
                fullMessage += message.getMessageBody();//获取短信的内容
            }
            sender.setText(address);
            content.setText(fullMessage);
            abortBroadcast();
        }  

    }
//监听广播是否发送成功的广播
    class SendStatusReceiver extends BroadcastReceiver {  

        @Override
        public void onReceive(Context context, Intent intent) {
            if (getResultCode() == RESULT_OK) {
                Toast.makeText(context, "Send succeeded", Toast.LENGTH_LONG)
                        .show();
            } else {
                Toast.makeText(context, "Send failed", Toast.LENGTH_LONG)
                        .show();
            }
        }  

    }  

}

Android API>23，需要改写

//接收类另一种写法

public class MessageDemo extends BroadcastReceiver {
    private static final String strACT = "android.provider.Telephony.SMS_RECEIVED";

public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(strACT)) {
StringBuilder sb = new StringBuilder();
Bundle bundle = intent.getExtras();
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
SmsMessage[] msg = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++) {
msg[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
}
for (SmsMessage currMsg : msg) {
sb.append("From:");
sb.append(currMsg.getDisplayOriginatingAddress());
sb.append("\nMessage:");
sb.append(currMsg.getDisplayMessageBody());
}
}
}

}
}

三、模拟短信发送

用Android Emulator模拟发送短信

接下来发短信打电话，设置gps什么的就选择相应的标签设置就好了
