发短信

1.在res/layout/activity_main.xml文件中，编辑界面控件代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/container"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.example.sms.MainActivity"    tools:ignore="MergeRootFrame"    android:orientation="vertical" >    <TextView        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/str_input_phone_number"/>    <EditText        android:id="@+id/phone_number_editText"        android:layout_width="fill_parent"        android:layout_height="wrap_content" />    <TextView        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/str_input_sms_content"/>    <EditText       android:id="@+id/sms_content_editText"        android:layout_width="fill_parent"        android:layout_height="wrap_content" />    <Button        android:id="@+id/send_sms_button"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/str_send_sms"  />    </LinearLayout>

2.在res/values/strings.xml中，定义需要用到的字符串

<?xml version="1.0" encoding="utf-8"?><resources>    <string name="app_name">SMS</string>    <string name="action_settings">Settings</string>    <string name="str_input_phone_number">请输入手机号码：</string>    <string name="str_input_sms_content">请输入内容：</string>    <string name="str_send_sms">发送短信</string>    <string name="str_remind_input_phone_number">请输入手机号码：</string>    <string name="str_remind_sms_send_finish">发送完成</string></resources>

3.在MainnActivity.java中，编写发送短信的逻辑代码

package com.example.sms;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 MainActivity extends Activity {private EditText phone_number_editText;private EditText sms_content_editText;private Button send_sms_button;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);phone_number_editText = (EditText) findViewById(R.id.phone_number_editText);sms_content_editText = (EditText) findViewById(R.id.sms_content_editText);send_sms_button = (Button) findViewById(R.id.send_sms_button);send_sms_button.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubString phone_number = phone_number_editText.getText().toString().trim();String sms_content = sms_content_editText.getText().toString().trim();if (phone_number.equals("")) {Toast.makeText(MainActivity.this,R.string.str_remind_input_phone_number,Toast.LENGTH_LONG).show();} else {SmsManager smsManager = SmsManager.getDefault();if (sms_content.length() > 70) {List<String> contents = smsManager.divideMessage(sms_content);for (String sms : contents) {smsManager.sendTextMessage(phone_number, null,sms_content, null, null);}} else {smsManager.sendTextMessage(phone_number, null,sms_content, null, null);}Toast.makeText(MainActivity.this,R.string.str_remind_sms_send_finish,Toast.LENGTH_SHORT).show();}}});}}

4.在AndroidManifest.xml中，声明发短信权限"android.permission.SEND_SMS"

<?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="14"        android:targetSdkVersion="19" />    <uses-permission android:name="android.permission.SEND_SMS" />    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.example.sms.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></manifest>
