短信发送器

一、界面

1.最终要实现的界面：

2.界面布局实现——activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/mobile" />
    
    <EditText 
        android:id="@+id/editMobile"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />
    
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/sms" />
    
    <EditText 
        android:id="@+id/editSms"
        android:layout_width="match_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/button"/>
</LinearLayout>

string.xml:

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

    <string name="app_name">短信发送器</string>
    <string name="mobile">请输入手机号</string>
    <string name="sms">请输入短信内容</string>
    <string name="button">发送短信</string>
    <string name="success">发送完成</string>
    <string name="hello_world">Hello world!</string>
    <string name="action_settings">Settings</string>

</resources>

二、权限

清单文件中申请权限：

<?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="14"
        android:targetSdkVersion="21" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".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>

    <uses-permission android:name="android.permission.SEND_SMS" />
    
</manifest>

三、代码实现

MainActivity.java:

package com.example.sms;

import java.util.ArrayList;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.gsm.SmsManager;
import android.text.InputFilter.LengthFilter;
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 {
    private EditText editMobile;
    private EditText editSms;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        Button button = (Button)findViewById(R.id.button);
        button.setOnClickListener(new onButtonClickListener());
        
        editMobile= (EditText)findViewById(R.id.editMobile);
        editSms= (EditText)findViewById(R.id.editSms);
    }

    private final class onButtonClickListener implements View.OnClickListener
    {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            String mobileText = editMobile.getText().toString();
            String smsText = editSms.getText().toString();
            SmsManager manager = SmsManager.getDefault();
            ArrayList<String> texts = manager.divideMessage(smsText);
            for(String text : texts)//采用增强for循环
            {
                manager.sendTextMessage(mobileText, null, text, null, null);
            }
            //提示用户短信发送完成,提示有3中方式
            //通知：1.状态栏通知     2.对话框通知：给用户的感觉比较生硬    3.吐司（Toast）：比较柔和
    //        Toast.makeText(getApplicationContext(), R.string.success, 0);//
            Toast.makeText(MainActivity.this, R.string.success,Toast.LENGTH_SHORT).show();
        }
        
    }
}
