要使用手机短信服务,在AndroidManifest.xml中必须添加短信服务权限

AndroidManifest.xml

<?xml version="1.0" encoding="UTF-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
     package="org.me.sendsms">
    <application>
         <activity android:name=".MainActivity" android:label="MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
    <uses-sdk android:minSdkVersion="3"/>
    <uses-permission android:name="android.permission.SEND_SMS"/><!--添加权限-->
</manifest>

MainActivity.java

 

package org.me.sendsms;

import android.app.Activity;
import android.app.PendingIntent;
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;
import java.util.List;

public class MainActivity extends Activity {

    private EditText txtNo;
    private EditText txtContent;
    private Button btnSend;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);
        txtNo = (EditText) findViewById(R.id.txtNo);
        txtContent = (EditText) findViewById(R.id.txtContent);
        btnSend = (Button) findViewById(R.id.btnSend);

        btnSend.setOnClickListener(new View.OnClickListener()  {

            @Override
            public void onClick(View v) {
                String strNo = txtNo.getText().toString();
                String strContent = txtContent.getText().toString();
                SmsManager smsManager = SmsManager.getDefault();
                PendingIntent sentIntent = PendingIntent.getBroadcast(MainActivity.this, 0, new Intent(), 0);
                //如果字数超过70,需拆分成多条短信发送
                if (strContent.length() > 70) {
                    List<String> msgs = smsManager.divideMessage(strContent);
                    for (String msg : msgs) {
                        smsManager.sendTextMessage(strNo, null, msg, sentIntent, null);                        
                    }
                } else {
                    smsManager.sendTextMessage(strNo, null, strContent, sentIntent, null);
                }
                Toast.makeText(MainActivity.this, "短信发送完成", Toast.LENGTH_LONG).show();
            }
        });
    }
}
