Android之路——第二个Android小程序（Android短信发送）

首先是布局的代码：main.xml

 <?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:text="@string/inputMobile"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content">
 </TextView>
 <EditText
     android:id="@+id/mobile"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content">
 </EditText>
 <TextView
     android:text="@string/inputMessage"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content">
 </TextView>
 <EditText
     android:id="@+id/Message"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content">
 </EditText>
 <Button
     android:text="@string/Submit"
     android:id="@+id/Submit"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content">
 </Button>
 </LinearLayout>

 

接下来是String.xml的代码：

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
     <string name="app_name">短信发送器</string>
     <string name="inputMobile">请输入手机号：</string>
     <string name="inputMessage">请输入短信内容：</string>
     <string name="Submit">发送短信</string>
 </resources>

 

 

上面两个都是位于res里面的。

接下来是src里面的代码MessageActivity：(由于在公司，没空写注释，等等回去补上)

 

 package cn.jason.android;
 import java.util.List;
 import android.app.Activity;
 import android.app.PendingIntent;
 import android.content.Intent;
 import android.os.Bundle;
 import android.telephony.gsm.SmsManager;
 import android.view.View;
 import android.widget.Button;
 import android.widget.EditText;
 import android.widget.Toast;
 public class messageActivity extends Activity {
     /** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);

         final EditText mobileNoEditText = (EditText) findViewById(R.id.mobile);
         final EditText messageEditText = (EditText) findViewById(R.id.Message);
         Button submitButton =  (Button) findViewById(R.id.Submit);

         submitButton.setOnClickListener(new View.OnClickListener() {

             public void onClick(View view) {
                 String moblileString = mobileNoEditText.getText().toString();
                 String messageString = messageEditText.getText().toString();
                 SmsManager smsManager = SmsManager.getDefault();
                 PendingIntent sendingIntent = PendingIntent.getBroadcast(messageActivity.this, 0, new Intent(), 0);
                 List<String> msgsList = smsManager.divideMessage(messageString);
                 for (String msg : msgsList) {
                     smsManager.sendTextMessage(moblileString, null, msg, sendingIntent, null);
                 }
                 Toast.makeText(messageActivity.this, "短信发送成功", Toast.LENGTH_LONG).show();
             }
         });



     }
 }

 

以上你都写了还是不能用的，最关键的一句是这样的：

 <?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
       package="cn.jason.android"
       android:versionCode="1"
       android:versionName="1.0">
     <application android:icon="@drawable/icon" android:label="@string/app_name">
         <activity android:name=".messageActivity"
                   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>

 

上面的最后一句如果没有的话是没法发短信的。这个是权限的设置。短信发送权限的设置。<uses-permission android:name="android.permission.SEND_SMS" />
