语音兰度短信

原理：获取来电短信内容，调用系统的语音朗读功能。

效果图：

具体代码如下：

1，获取短信息：

[html] view plaincopy

1. package com.internal.message;  
2.   
3. import android.content.BroadcastReceiver;  
4. import android.content.Context;  
5. import android.content.Intent;  
6. import android.database.Cursor;  
7. import android.net.Uri;  
8. import android.os.Bundle;  
9. import android.provider.ContactsContract;  
10. import android.telephony.SmsMessage;  
11. import android.test.suitebuilder.annotation.SmallTest;  
12.   
13. public class SmsMessageReceiver extends BroadcastReceiver {  
14.      
15.     @Override  
16.     public void onReceive(Context context, Intent intent) {  
17.         Bundle extras = intent.getExtras();  
18.         if (extras == null)  
19.             return;  
20.   
21.         Object[] pdus = (Object[]) extras.get("pdus");  
22.   
23.             SmsMessage message = SmsMessage.createFromPdu((byte[]) pdus[0]);  
24.             String fromAddress = message.getOriginatingAddress();  
25.             String fromDisplayName = fromAddress;  
26.   
27.             Uri uri;  
28.             String[] projection;  
29.   
30.             uri = Uri.withAppendedPath(  
31.                     ContactsContract.PhoneLookup.CONTENT_FILTER_URI,  
32.                     Uri.encode(fromAddress));  
33.             projection = new String[] { ContactsContract.PhoneLookup.DISPLAY_NAME };  
34.   
35.             // 查找联系人  
36.             Cursor cursor = context.getContentResolver().query(uri, projection, null, null, null);  
37.             if (cursor != null) {  
38.                 if (cursor.moveToFirst())  
39.                     fromDisplayName = cursor.getString(0);  
40.   
41.                 cursor.close();  
42.                 cursor=null;  
43.             }  
44.   
45.             // 启动消息显示器  
46.             Intent di = new Intent();  
47.             di.setClass(context, SmsReceivedDialog.class);  
48.             di.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);  
49.             di.putExtra(MsgAction.SMS_FROM_ADDRESS_EXTRA, fromAddress);  
50.             di.putExtra(MsgAction.SMS_FROM_DISPLAY_NAME_EXTRA, fromDisplayName);  
51.             di.putExtra(MsgAction.SMS_MESSAGE_EXTRA, message.getMessageBody().toString());  
52.             context.startActivity(di);  
53.     
54.     }  
55.       
56. }  

2,注册广播：

[html] view plaincopy

1. <receiver android:name="com.internal.message.SmsMessageReceiver" android:enabled="false">  
2.             <intent-filter>  
3.                 <action android:name="android.provider.Telephony.SMS_RECEIVED" />  
4.             </intent-filter>  
5.         </receiver>  

3，消息显示及朗读功能：

[html] view plaincopy

1. package com.internal.message;  
2.   
3. import java.util.Locale;  
4.   
5. import com.internal.main.R;

35.         mMessage = getIntent().getExtras().getString(MsgAction.SMS_MESSAGE_EXTRA);  
36.   
37.         mFullBodyString = String.format(  
38.                 getResources().getString(R.string.sms_speak_string_format),  
39.                 " "+mFromDisplayName,

47.         if (status == TextToSpeech.SUCCESS) {  
48.             int result = mTts.setLanguage(Locale.US);  
49.             if (result == TextToSpeech.LANG_MISSING_DATA  
50.                     || result == TextToSpeech.LANG_NOT_SUPPORTED) {  
51.                 Log.e(TAG, "TTS language is not available.");  
52.             } else {  
53.                 mTts.speak(mFullBodyString, TextToSpeech.QUEUE_ADD, null);  
54.             }  
55.         } else {  
56.             // Initialization failed.  
57.             Log.e(TAG, "Could not initialize TTS.");  
58.         }  
59.     }  
60.   
61.     @Override

66.                     .setIcon(android.R.drawable.ic_dialog_email)  
67.                     .setTitle("Message Received")  
68.                     .setMessage(mFullBodyString)  
69.                     .setPositiveButton("replay", new DialogInterface.OnClickListener() {  
70.                         public void onClick(DialogInterface dialog, int whichButton) {  
71.                               
72.                             Intent i = new Intent();  
73.                             i.setClass(SmsReceivedDialog.this, SendMsgActivity.class);  
74.                             i.putExtra(MsgAction.SMS_RECIPIENT_EXTRA, mFromAddress);  
75.                             startActivity(i);  
76.   
77.                             dialog.dismiss();  
78.                             finish();  
79.                         }

最后别忘了添加权限，要不不能读取信息呀！
