android 短信发送器

简单界面截图如下：

一、要使用发送短信服务，首先要在AndroidManifest.xml清单文件中添加该权限：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.sms"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="8" />

    <!-- 添加短信发送权限 -->
    <uses-permission android:name="android.permission.SEND_SMS" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".SMSActivity"
            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>

</manifest>

二、在strings.xml中增加需要的变量

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="hello">Hello World, SMSActivity!</string>
    <string name="app_name">SMS</string>
    <string name="input_phone_number">请输入手机号：</string>
    <string name="empty_phone_number">手机号码不能为空</string>
    <string name="input_sms_content">请输入短信内容：</string>
    <string name="empty_sms_content">短信内容不能为空</string>
    <string name="send_sms">发送短信</string>
    <string name="send_sms_success">短信发送成功</string>

</resources>

三、编写界面layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/input_phone_number" />

    <EditText
        android:id="@+id/etPhoneNumber"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:ems="10"
        android:inputType="phone" >

        <requestFocus />
    </EditText>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/input_sms_content" />

    <EditText
        android:id="@+id/etSmsContent"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:ems="10"
        android:inputType="textMultiLine" />

    <Button
        android:id="@+id/sendSms"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/send_sms" />

</LinearLayout>

四、编写activity

package com.example.sms;

import java.util.List;

import android.app.Activity;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class SMSActivity extends Activity {
	private EditText mPhoneNumber = null;
	private EditText mSmsContent = null;
	private Button mSendSms = null;

	private SmsManager mSmsManager = SmsManager.getDefault( );

	/** Called when the activity is first created. */
	@Override
	public void onCreate( Bundle savedInstanceState ) {
		super.onCreate( savedInstanceState );
		setContentView( R.layout.main );
		mPhoneNumber = ( EditText ) findViewById( R.id.etPhoneNumber );
		mSmsContent = ( EditText ) findViewById( R.id.etSmsContent );
		mSendSms = ( Button ) findViewById( R.id.sendSms );
		mSendSms.setOnClickListener( new OnClickListener( ) {

			@Override
			public void onClick( View v ) {
				String phoneNumber = mPhoneNumber.getText( ).toString( );
				if ( phoneNumber.equals( "" ) ) {
					Toast.makeText( getApplicationContext( ), R.string.empty_phone_number, Toast.LENGTH_LONG ).show( );
					return;
				}

				String smsContent = mSmsContent.getText( ).toString( );
				if ( smsContent.equals( "" ) ) {
					Toast.makeText( getApplicationContext( ), R.string.empty_sms_content, Toast.LENGTH_LONG ).show( );
					return;
				}

				PendingIntent sentIntent = PendingIntent.getBroadcast( getApplicationContext( ), 0, new Intent( ), 0 );

				if ( smsContent.length( ) > 70 ) {
					List<String> msgList = mSmsManager.divideMessage( smsContent );
					for ( int i = 0, size = msgList.size( ); i < size; i++ ) {
						mSmsManager.sendTextMessage( phoneNumber, null, msgList.get( i ), sentIntent, null );
					}
				} else {
					mSmsManager.sendTextMessage( phoneNumber, null, smsContent, sentIntent, null );
				}
				Toast.makeText( getApplicationContext( ), R.string.send_sms_success, Toast.LENGTH_LONG );
			}
		} );
	}
}
