實現(xiàn) Android 發(fā)短信功能

ruanjwei2011

和上一篇文章一樣，發(fā)短信在android開發(fā)中也是很常用的功能。

運行效果如圖所示：

首先新建一個android project

在string.xml中定義需要用到的字符串：

1. <?xml version="1.0" encoding="utf-8"?>
   
2. <resources>
   
3.     <string name="hello">Hello World, MainActivity!>
   
4.     <string name="app_name">發(fā)短信程序</string>
   
5.     <string name="str_input_phone_number">請輸入手機(jī)號</string>
   
6.     <string name="str_input_sms_content">請輸入短信內(nèi)容</string>
   
7.     <string name="str_send_sms">發(fā)送短信</string>
   
8.     <string name="str_remind_input_phone_number">請輸入手機(jī)號</string>
   
9.     <string name="str_remind_sms_send_finish">發(fā)送完成</string>
   
10. </resources>

在main.xml中編輯界面控件代碼：

1. <?xml version="1.0" encoding="utf-8"?>
   
2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   
3.     android:orientation="vertical"
   
4.     android:layout_width="fill_parent"
   
5.     android:layout_height="fill_parent"
   
6.     >
   
7.     <TextView
   
8.      android:layout_width="fill_parent"
   
9.      android:layout_height="wrap_content"
   
10.      android:text="@string/str_input_phone_number"
    
11.      />
    
12.     <EditText
    
13.         android:layout_width="fill_parent"
    
14.         android:layout_height="wrap_content"
    
15.         android:id="@+id/phone_number_editText"
    
16.         />
    
17.     <TextView
    
18.         android:layout_width="fill_parent"
    
19.         android:layout_height="wrap_content"
    
20.         android:text="@string/str_input_sms_content"
    
21.         />        
    
22.     <EditText
    
23.         android:layout_width="fill_parent"
    
24.         android:layout_height="wrap_content"
    
25.         android:id="@+id/sms_content_editText"
    
26.         />        
    
27.     <Button
    
28.         android:layout_width="wrap_content"
    
29.         android:layout_height="wrap_content"
    
30.         android:text="@string/str_send_sms"
    
31.         android:id="@+id/send_sms_button"
    
32.         />        
    
33. </LinearLayout>

最后在MainActivity中編寫發(fā)送短信的邏輯代碼：

1. package com.sms.ui;
   
2. 
   
3. import java.util.List;
   
4. 
   
5. import android.app.Activity;
   
6. import android.os.Bundle;
   
7. import android.telephony.SmsManager;
   
8. import android.view.View;
   
9. import android.view.View.OnClickListener;
   
10. import android.widget.Button;
    
11. import android.widget.EditText;
    
12. import android.widget.Toast;
    
13. 
    
14. public class MainActivity extends Activity {
    
15.     /** Called when the activity is first created. */
    
16.     @Override
    
17.     public void onCreate(Bundle savedInstanceState) {
    
18.         super.onCreate(savedInstanceState);
    
19.         setContentView(R.layout.main);
    
20.         
    
21.         phone_number_editText = (EditText) findViewById(R.id.phone_number_editText);
    
22.         sms_content_editText = (EditText) findViewById(R.id.sms_content_editText);
    
23.         send_sms_button = (Button) findViewById(R.id.send_sms_button);
    
24.         
    
25.         send_sms_button.setOnClickListener(new OnClickListener() {
    
26. 
    
27.             @Override
    
28.             public void onClick(View arg0) {
    
29.                 String phone_number = phone_number_editText.getText().toString().trim();
    
30.                 String sms_content = sms_content_editText.getText().toString().trim();
    
31.                 if(phone_number.equals("")) {
    
32.                     Toast.makeText(MainActivity.this, R.string.str_remind_input_phone_number, Toast.LENGTH_LONG).show();
    
33.                 } else {
    
34.                     SmsManager smsManager = SmsManager.getDefault();
    
35.                     if(sms_content.length() > 70) {
    
36.                         List<String> contents = smsManager.divideMessage(sms_content);
    
37.                         for(String sms : contents) {
    
38.                             smsManager.sendTextMessage(phone_number, null, sms, null, null);
    
39.                         }
    
40.                     } else {
    
41.                      smsManager.sendTextMessage(phone_number, null, sms_content, null, null);
    
42.                     }
    
43.                     Toast.makeText(MainActivity.this, R.string.str_remind_sms_send_finish, Toast.LENGTH_SHORT).show();
    
44.                 }
    
45.             }     
    
46.         });
    
47.     }
    
48.     
    
49.     private EditText phone_number_editText;
    
50.     private EditText sms_content_editText;
    
51.     private Button send_sms_button;
    
52. }
