短信SMS的接收

article/2025/9/30 3:45:21

近日，看了《第一行代码》有关短信接收的内容，就总结了一下。

1.手机接收到一条短信时，系统会发出一条android.provider.Telephy.SMS_RECEIVER的广播，这条广播带有短信的所有数据

2.首先定义xml文件

<LinearLayout android:layout_width="match_parent"android:layout_height="50dp"><TextView android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_vertical"android:padding="10dp"android:text="From:"/><TextView android:id="@+id/sender"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_vertical"/></LinearLayout><LinearLayout android:layout_width="match_parent"android:layout_height="50dp"><TextView android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_vertical"android:padding="10dp"android:text="Content:"/><TextView android:id="@+id/content"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_vertical"/>

2.MainActivity

public class MainActivity extends ActionBarActivity {private TextView sender;private TextView content;private IntentFilter receiverFilter;private MessageReceiver messageReceiver;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);sender=(TextView)findViewById(R.id.sender);content=(TextView)findViewById(R.id.content);receiverFilter = new IntentFilter();receiverFilter.addAction("android.provider.Telephony.SMS_RECEIVED");receiverFilter.setPriority(100);messageReceiver=new MessageReceiver();//第一个参数表示将要执行的方法，第二个表示接受的广播
    registerReceiver(messageReceiver, receiverFilter);}@Overrideprotected void onDestroy() {super.onDestroy();//动态注册广播，要在ondestroy（）方法中取消注册
        unregisterReceiver(messageReceiver);}class MessageReceiver extends BroadcastReceiver{@Overridepublic void onReceive(Context context, Intent intent) {Bundle bundle=intent.getExtras();Object[] pdus=(Object[]) bundle.get("pdus");SmsMessage[] messages=new SmsMessage[pdus.length];for(int i=0;i<messages.length;i++){messages[i]=SmsMessage.createFromPdu((byte[]) pdus[i]);}//获取发送方号码String address = messages[0].getOriginatingAddress();String fullMessage="";for(SmsMessage message:messages){fullMessage +=message.getMessageBody(); //获取短信内容
            }sender.setText(address);content.setText(fullMessage);//abortBroadcast();
        }}}
