今天学习了android短信的发送与接收。
首先是MainActivity.java

public class MainActivity extends Activity {    private TextView sender;    private TextView content;    private EditText msgInput;    private Button send;    private EditText to;    private IntentFilter receiveFilter;    private MessageReceiver messageReceiver;    private IntentFilter sendFilter;    private SendStatusReceiver sendStatusReceiver;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        sender = (TextView) findViewById(R.id.sender);        content = (TextView) findViewById(R.id.content);        to = (EditText) findViewById(R.id.to);        send = (Button) findViewById(R.id.send);        msgInput = (EditText) findViewById(R.id.msg_input);        receiveFilter = new IntentFilter();        receiveFilter.addAction("android.provider.Telephony.SMS_RECEIVED");        messageReceiver = new MessageReceiver();        registerReceiver(messageReceiver,receiveFilter);        sendFilter = new IntentFilter();        sendFilter.addAction("SENT_SMS_ACTION");        sendStatusReceiver = new SendStatusReceiver();        registerReceiver(sendStatusReceiver,sendFilter);        send.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                SmsManager smsManager = SmsManager.getDefault();                Intent sendIntent = new Intent("SENT_SMS_ACTION");                PendingIntent pi = PendingIntent.getBroadcast(MainActivity.this,0,sendIntent,0);                smsManager.sendTextMessage(to.getText().toString(),null,msgInput.getText().toString(),pi,null);            }        });    }    @Override    protected void onDestroy(){        super.onDestroy();        unregisterReceiver(messageReceiver);        unregisterReceiver(sendStatusReceiver);    }//    接收短信内部类    class MessageReceiver extends BroadcastReceiver {        public MessageReceiver() {        }        @Override        public void onReceive(Context context, Intent intent) {            Object[] pdus = (Object[])intent.getSerializableExtra("pdus");  //提取短信消息            String format = intent.getStringExtra("format");            SmsMessage[] messages = new SmsMessage[pdus.length];            for (int i = 0; i<messages.length;i++){                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {                    messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i],format);                }            }            String address = messages[0].getOriginatingAddress();  //获取发送方号码            String fullMessage = "";            for (SmsMessage message : messages){                fullMessage +=message.getMessageBody();//获取短信内容            }            sender.setText(address);            content.setText(fullMessage);        }    }//    内部类监听短信发送是否成功    class SendStatusReceiver extends BroadcastReceiver{        @Override        public void onReceive(Context context,Intent intent){            if(getResultCode() == RESULT_OK){   //若发送成功                Toast.makeText(context, "发送成功", Toast.LENGTH_SHORT).show();                to.setText("");                msgInput.setText("");            }else {                Toast.makeText(context, "发送失败", Toast.LENGTH_SHORT).show();            }        }    }}

发送和接收需要声明权限

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

布局文件：activity_main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <LinearLayout        android:layout_width="match_parent"        android:layout_height="50dp"        android:orientation="horizontal">        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_vertical"            android:padding="10dp"            android:text="发送人:"/>        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_vertical"            android:id="@+id/sender"/>    </LinearLayout>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="50dp"        android:orientation="horizontal">        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_vertical"            android:padding="10dp"            android:text="内容:"/>        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_vertical"            android:id="@+id/content"/>    </LinearLayout>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="50dp"        android:orientation="horizontal">        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="接受人:"/>        <EditText            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1"            android:layout_gravity="center_vertical"            android:id="@+id/to"/>    </LinearLayout>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="50dp"        android:orientation="horizontal">        <EditText            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1"            android:layout_gravity="center_vertical"            android:id="@+id/msg_input"/>        <Button            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_vertical"            android:text="发送"            android:id="@+id/send"/>    </LinearLayout></LinearLayout>

接收短信重写内部类：

class MessageReceiver extends BroadcastReceiver {        public MessageReceiver() {        }        @Override        public void onReceive(Context context, Intent intent) {            Object[] pdus = (Object[])intent.getSerializableExtra("pdus");  //提取短信消息            String format = intent.getStringExtra("format");            SmsMessage[] messages = new SmsMessage[pdus.length];            for (int i = 0; i<messages.length;i++){                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {                    messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i],format);                }            }            String address = messages[0].getOriginatingAddress();  //获取发送方号码            String fullMessage = "";            for (SmsMessage message : messages){                fullMessage +=message.getMessageBody();//获取短信内容            }            sender.setText(address);            content.setText(fullMessage);        }    }
