Android 发送短信功能

1）关键代码如下

1.MainActivity.java

package com.example.androidtestapp;import android.os.Bundle;import android.app.Activity;import android.app.PendingIntent;import android.content.Intent;import android.telephony.gsm.SmsManager;import android.view.Menu;import android.view.View;import android.widget.Button;public class MainActivity extends Activity {private Button button1=null;private String phoneNumberString="10086";private String msgString="10086";@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);button1=(Button)findViewById(R.id.button1);button1.setText("send "+msgString+" to "+phoneNumberString);button1.setOnClickListener(new Button.OnClickListener() {@Overridepublic void onClick(View arg0) {/*建构一获得default instance的SmsManager对象*/SmsManager smsManager=SmsManager.getDefault();/*收件人电话号码格式与短信字数没有超过70个字符，发送短信*/PendingIntent pendingIntent=PendingIntent.getBroadcast(MainActivity.this, 0, new Intent(), 0);smsManager.sendTextMessage(phoneNumberString, null , msgString, pendingIntent,null);}});}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}}

2.需要添加发送短信的权限

AndroidManifest.xml代码如下

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.androidtestapp"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="17" />    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.example.androidtestapp.MainActivity"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>    </application><!--添加可以发送短信的权限 --><uses-permission android:name="android.permission.SEND_SMS"/></manifest>
