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
