Android开发app实现发送短信功能

程序使用手机发短信的方法

短信收发：

◆发送短信只需要几行代码，如下：

SmsManager sms = SmsManager.getDefault(); PendingIntent pi = PendingIntent.getBroadcast(this, 0, new Intent(), 0); sms.sendTextMessage(phoneNumber, null, MsgStr, pi, null);

其中参数phoneNumber和MsgStr均是String类型，表示接收方的电话号码和短信内容

◆接收短信主要是继承BroadcaseReceiver 类 ,覆盖onReceive 函数：

package com.android.TinySMS;   import android.app.Activity; import android.app.PendingIntent; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.telephony.gsm.SmsManager; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.Toast;   public class TinySMS extends Activity {     public static final String SMS_ACTION = "com.android.TinySMS.RESULT"; // private TextView message;     private Button snd;     private EditText tel;     private EditText txt;     private SentReceiver receiver = new SentReceiver();       private class SentReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) {     if (intent.getAction().equals(SMS_ACTION)) {      int code = getResultCode();      //短消息发送成功      if(code == Activity.RESULT_OK)      Toast.makeText(TinySMS.this, R.string.msg_sent,      Toast.LENGTH_SHORT).show();     } }     };       /** Called when the activity is first created. */     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);      tel = (EditText) findViewById(R.id.EditText01);      tel.setText("5554");  //模拟器之间互发短信      txt = (EditText) findViewById(R.id.EditText02);      txt.setText("我用自己的程序试试发短信。");      snd = (Button) findViewById(R.id.Button01);           snd.setOnClickListener(new View.OnClickListener() {          public void onClick(View arg0) {           String phoneNo = tel.getText().toString();           String message = txt.getText().toString();           if (phoneNo.length()>0 && message.length()>0){           sendSMS(phoneNo, message);           } else {           Toast.makeText(TinySMS.this,           "请重新输入电话号码和短信内容",           Toast.LENGTH_LONG).show();           }          }        });     }       private void sendSMS(String address, String content)     {      SmsManager manager = SmsManager.getDefault();      Intent i = new Intent(SMS_ACTION);      //生成PendingIntent，当消息发送完成，接收到广播      PendingIntent sentIntent = PendingIntent.getBroadcast(     this,     0,     i,     PendingIntent.FLAG_ONE_SHOT);      manager.sendTextMessage(      address,      null,      content,      sentIntent,      null);     } }

如果要收发短信，还需在AndroidManifest.xml中声明权限：

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