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";
@Override
protected 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() {

@Override
public 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);
}
});
}


@Override
public 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>
