android应用程序---短信发送器

（1）先将设计的软件界面中的字符串存储起来
strings.xml是位于values文件夹下面

<?xml version="1.0" encoding="utf-8"?><resources>    <string name="app_name">Message</string>    <string name="action_settings">Settings</string>    <string name="number">请输入电话号码</string>    <string name="content">请输入短信内容</string>    <string name="button">发送</string>    <string name="success">发送完成</string></resources>

（2）在activity_main.xml里面设计软件界面
activity_main.xml是位于layout文件夹下面

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:orientation="vertical"    tools:context="com.dqpi.message.MainActivity" >    <TextView        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/number"         />    <EditText        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/number"         android:id="@+id/number"        />     <TextView        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/content"        />     <EditText        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/content"          android:id="@+id/content"         />      <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/button"         android:id="@+id/button"        /></LinearLayout>

（3）在MainActivity.java中写逻辑代码

package com.dqpi.message;import java.util.ArrayList;import android.app.Activity;import android.os.Bundle;import android.telephony.SmsManager;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.widget.Button;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends Activity {    /**     * 定义全局变量numberText和contentText     */    private EditText numberText;    private EditText contentText;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        //查找number所在的地方        numberText = (EditText)this.findViewById(R.id.number);        //查找content所在的地方        contentText = (EditText)this.findViewById(R.id.content);        //查找button所在的地方        Button button = (Button)this.findViewById(R.id.button);        //对button进行响应事件处理        button.setOnClickListener(new ButtOnClickListener());    }    /**     * 处理button的响应事件     * @author Mr Li     *     */    private final class ButtOnClickListener implements View.OnClickListener{        @Override        public void onClick(View v) {            //获得number的值            String number = numberText.getText().toString();            //获得content的值            String content = contentText.getText().toString();            //创建SmsManager对象            SmsManager manager = SmsManager.getDefault();            //短信内容            ArrayList<String> texts = manager.divideMessage(content);            for(String text:texts){                manager.sendTextMessage(number, null, text, null, null);            }            //短信发送完成的通知            Toast.makeText(MainActivity.this, R.string.success, Toast.LENGTH_LONG).show();        }    }    @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;    }    @Override    public boolean onOptionsItemSelected(MenuItem item) {        // Handle action bar item clicks here. The action bar will        // automatically handle clicks on the Home/Up button, so long        // as you specify a parent activity in AndroidManifest.xml.        int id = item.getItemId();        if (id == R.id.action_settings) {            return true;        }        return super.onOptionsItemSelected(item);    }}

（4）看看R.java文件
R文件是在创建的android application project项目的gen文件夹下面，这个文件不需要自己手动修改。

/* AUTO-GENERATED FILE.  DO NOT MODIFY. * * This class was automatically generated by the * aapt tool from the resource data it found.  It * should not be modified by hand. */package com.dqpi.message;public final class R {    public static final class attr {    }    public static final class dimen {        /**  Default screen margins, per the Android Design guidelines.          Example customization of dimensions originally defined in res/values/dimens.xml         (such as screen margins) for screens with more than 820dp of available width. This         would include 7" and 10" devices in landscape (~960dp and ~1280dp respectively).         */        public static final int activity_horizontal_margin=0x7f040000;        public static final int activity_vertical_margin=0x7f040001;    }    public static final class drawable {        public static final int ic_launcher=0x7f020000;        public static final int msm=0x7f020001;    }    public static final class id {        public static final int action_settings=0x7f080003;        public static final int button=0x7f080002;        public static final int content=0x7f080001;        public static final int number=0x7f080000;    }    public static final class layout {        public static final int activity_main=0x7f030000;    }    public static final class menu {        public static final int main=0x7f070000;    }    public static final class string {        public static final int action_settings=0x7f050001;        public static final int app_name=0x7f050000;        public static final int button=0x7f050004;        public static final int content=0x7f050003;        public static final int number=0x7f050002;        public static final int success=0x7f050005;    }    public static final class style {        /**         Base application theme, dependent on API level. This theme is replaced        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.

Base application theme for API 11+. This theme completely replaces        AppBaseTheme from res/values/styles.xml on API 11+ devices. API 11 theme customizations can go here.         Base application theme for API 14+. This theme completely replaces        AppBaseTheme from BOTH res/values/styles.xml and        res/values-v11/styles.xml on API 14+ devices. API 14 theme customizations can go here.          */        public static final int AppBaseTheme=0x7f060000;        /**  Application theme.  All customizations that are NOT specific to a particular API-level can go here.          */        public static final int AppTheme=0x7f060001;    }}

（5）部署到手机上面，进行功能测试。
