如何阅读android中即将发布的消息的消息内容？

Question

我想以编程方式在android中读取新传入SMS的消息正文.

我尝试了一些但不会返回任何内容:

Uri uri = Uri.parse("content://sms/inbox");
        ContextWrapper context = null;      
        Cursor c = context.getContentResolver().query(uri, null, null ,null,null);      
        String body = null; 
        String number=null;
        if(c.moveToFirst()) {        
           body = c.getString(c.getColumnIndexOrThrow("body")).toString();
           number = c.getString(c.getColumnIndexOrThrow("address")).toString();
        }
        c.close();

我在班级网站上发布了一些关于此的示例程序.以下是示例阅读短信示例 以下是一段代码.基本上你可以注册广播接收器来收听SMS_Receive并检查以下内容.

Intent intent = getIntent();
    Bundle bundle = intent.getBundleExtra("mySMS");

    if (bundle != null) {
        Object[] pdus = (Object[])bundle.get("pdus");
        SmsMessage sms = SmsMessage.createFromPdu((byte[])pdus[0]);
        Log.i("mobile.cs.fsu.edu", "smsActivity : SMS is <" +  sms.getMessageBody() +">");

        //strip flag
        String message = sms.getMessageBody();
        while (message.contains("FLAG"))
            message = message.replace("FLAG", "");

        TextView tx = (TextView) findViewById(R.id.TextBox);
        tx.setText(message);            
    } else
        Log.i("mobile.cs.fsu.edu", "smsActivity : NULL SMS bundle");

下面是读取传入消息并在列表视图中显示的代码段,不要忘记在清单文件中添加权限:

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

这里的代码:

 listitem=(ListView)findViewById(R.id.ListView);

        Uri mSmsQueryUri = Uri.parse("content://sms/inbox");
        List<String> messages = new ArrayList<String>();

        Cursor cursor = null;
        try {
            cursor = getContentResolver().query(mSmsQueryUri, null, null, null, null);
            if (cursor == null) {
                Log.i(TAG, "cursor is null. uri: " + mSmsQueryUri);

            }
            for (boolean hasData = cursor.moveToFirst(); hasData; hasData = cursor.moveToNext()) {
                final String body = cursor.getString(cursor.getColumnIndexOrThrow("body"));
                messages.add(body);
            }
        } catch (Exception e) {
            Log.e(TAG, e.getMessage());
        } finally {
            cursor.close();
        }

        listitem.setAdapter(new ArrayAdapter<String>(ReadMessage.this, android.R.layout.simple_list_item_1,messages));
