android-基础知识:smsManager.sendTextMessage() 发送短信息

  利用类 SmsManager 发送信息, smsManager 为 SmsManager 一个默认的实例. SmsManager smsManager = SmsManager.getDefault();

  smsManager.sendTextMessage(destinationAddress, scAddress, text, sentIntent, deliveryIntent)  

  destinationAddress: 收件人号码 

  scAddress: 短信中心服务号码, 这里设置为null 

  text: 发送内容

  sentIntent: 发送短信结果状态信号(是否成功发送),new 一个Intent , 操作系统接收到信号后将广播这个Intent.此过程为异步.

  deliveryIntent: 对方接收状态信号(是否已成功接收).

  由于需要用到系统发送信息功能, 要在AndroidMainfest.xml 加入 <uses-permission android: name="android.permisson.SEND_SMS" />

  

     AndroidMainfest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package
="com.PhoneSMS.melody"
android:versionCode
="1"
android:versionName
="1.0">
<uses-sdk android:minSdkVersion="10"/>

<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".PhoneSMSActivity"
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>
<uses-permission android:name="android.permission.SEND_SMS"/>
</manifest>

 

  1.界面设计 res/layout/main.xml

 

     main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation
="vertical" android:layout_width="fill_parent"
android:layout_height
="fill_parent">
<!-- 编辑接收号码 -->
<TextView android:layout_width="fill_parent"
android:layout_height
="wrap_content" android:text="@string/textSMSTo"/>
<EditText android:layout_width="fill_parent"
android:layout_height
="wrap_content" android:lines="3" android:hint="@string/edtSMSTo"
android:id
="@+id/edtSMSTo"/>
<!-- 编辑发送内容 -->
<TextView android:layout_width="fill_parent"
android:layout_height
="wrap_content" android:text="@string/textContent"/>
<EditText android:layout_width="fill_parent"
android:layout_height
="wrap_content" android:lines="3"
android:hint
="@string/edtContent" android:id="@+id/edtContent"/>
<!-- 发送 -->
<Button android:layout_width="wrap_content"
android:layout_height
="wrap_content" android:text="@string/btnSent"
android:id
="@+id/btnSent"/>

</LinearLayout>

 

  2.字符变量 res/values/strings.xml

 

     strings.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="hello">Hello World, PhoneSMSActivity!</string>
<string name="app_name">PhoneSMS</string>
<string name="textSMSTo">收件人</string>
<string name="edtSMSTo">收件人号码</string>
<string name="textContent">发送内容</string>
<string name="edtContent">输入内容</string>
<string name="btnSent">发送</string>
</resources>


  3.Activity代码编写

  

     PhoneSMSActivity.java
package com.PhoneSMS.melody;

import java.util.List;

import android.app.Activity;
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 PhoneSMSActivity extends Activity implements OnClickListener {
private EditText edtSMSTo = null; // 收件人控件
private EditText edtContent = null; // 发送内容控件
private Button btnSent = null; // 发送btn 控件
private String SMSTo = null; // 收件人号码
private String SMSContent = null; // 发送内容


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

/**
* 获取控件
*/
edtSMSTo = (EditText) this.findViewById(R.id.edtSMSTo);
edtContent = (EditText) this.findViewById(R.id.edtContent);
btnSent = (Button) this.findViewById(R.id.btnSent);

// 获取收件人号码
SMSTo = edtSMSTo.getText().toString();
// 获取发送内容
SMSContent = edtContent.getText().toString();
// 设置监听事件
btnSent.setOnClickListener(this);
}

@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnSent:
/**
* 实现短信发送功能
*/
// 获取默认短信管理对象
SmsManager smsManager = SmsManager.getDefault();
// 判断发送内容字数(一件信息最多70 字)
if(SMSContent.length() <= 70) {
smsManager.sendTextMessage(SMSTo, null, SMSContent, null, null);
}else{
// SmsManger 类中 divideMessage 会将信息按每70 字分割
List<String
> smsDivs = smsManager.divideMessage(SMSContent);
for(String sms : smsDivs) {
smsManager.sendTextMessage(SMSTo, null, sms, null, null);

}
}
Toast.makeText(PhoneSMSActivity.this, "信息已发送", Toast.LENGTH_SHORT);
break;
}
}
}
