Android开发5：短信发送器

1、短信发送，同样使用的是系统的服务，需要加上权限
AndroidManifest.xml代码

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.sendmessage.activity" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".SendMessageActivity" 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-sdk android:minSdkVersion="4" /><uses-permission android:name="android.permission.SEND_SMS" /></manifest>

2、设计界面

main.xml代码

<?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"><TextView android:layout_width="fill_parent"android:layout_height="wrap_content" android:text="@string/phonetext" /><EditText android:id="@+id/phoneNum" android:layout_width="fill_parent"android:layout_height="wrap_content" /><TextView android:layout_width="fill_parent"android:layout_height="wrap_content" android:text="@string/contexttext" /><EditText android:id="@+id/content" android:layout_width="fill_parent"android:layout_height="wrap_content" android:minLines="3" /><Button android:id="@+id/button" android:layout_width="wrap_content"android:layout_height="wrap_content" android:text="@string/buttontext" /></LinearLayout>

strings.xml代码

<?xml version="1.0" encoding="utf-8"?><resources> <string name="hello">Hello World, SendMessageActivity!</string> <string name="app_name">吴版短信发送</string> <string name="phonetext">请输入号码：</string> <string name="contexttext">请输入短信内容</string> <string name="buttontext">发送短信</string> <string name="info">短信发送成功</string></resources>

3、Activity

SendMessageActivity.java代码

package com.sendmessage.activity;import java.util.List;import android.app.Activity;import android.os.Bundle;import android.telephony.SmsManager;import android.view.View;import android.widget.Button;import android.widget.EditText;import android.widget.Toast;public class SendMessageActivity extends Activity {/** Called when the activity is first created. */private EditText phoneText;private EditText contentText;private Button button;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);phoneText = (EditText) this.findViewById(R.id.phoneNum);contentText = (EditText) this.findViewById(R.id.content);button = (Button) this.findViewById(R.id.button);button.setOnClickListener(new View.OnClickListener() {public void onClick(View v) {sendMessage();}});}/** * */private void sendMessage() {// 获取文本框中的内容String phone_num = phoneText.getText().toString();String content = contentText.getText().toString();SmsManager smsMagager = SmsManager.getDefault();if (content.length() > 70) {List<String> sms = smsMagager.divideMessage(content);for (String con : sms) {smsMagager.sendTextMessage(phone_num, null, con, null, null);}} else {smsMagager.sendTextMessage(phone_num, null, content, null, null);}Toast.makeText(this, R.string.info, 1);}}
