问题描述

点击返回按钮时 broadcast receiver 停止

我创建了一个android sms 应用程序。我使用下面的代码来发送sms。

public void sendSms(final String phoneNumber final String message){    String SENT = ""SMS_SENT"";    String DELIVERED = ""SMS_DELIVERED"";    PendingIntent sentPI = PendingIntent.getBroadcast(this 0        new Intent(SENT) 0);    PendingIntent deliveredPI = PendingIntent.getBroadcast(this 0            new Intent(DELIVERED)0);   //--- When the SMS has been sent --    sendBroadcastReceiver=new BroadcastReceiver() {        @Override        public void onReceive(Context context Intent intent) {            // TODO Auto-generated method stub            switch (getResultCode()) {                case Activity.RESULT_OK:                    Toast.makeText(getBaseContext()SMS sent""                    Toast.LENGTH_SHORT).show();                    ContentValues values = new ContentValues();                    values.put(""address"" phoneNumber);                    values.put(""body"" message);                    getContentResolver().insert(Uri.parse(""content://sms/sent"") values);                    break;                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:                    Toast.makeText(getBaseContext()Generic failure""                    Toast.LENGTH_SHORT).show();                    break;                case SmsManager.RESULT_ERROR_NO_SERVICE:                    Toast.makeText(getBaseContext()No service""                    Toast.LENGTH_SHORT).show();                    ContentValues values1 = new ContentValues();                    values1.put(""address"" phoneNumber);                    values1.put(""body"" message);                    getContentResolver().insert(Uri.parse(""content://sms/queued"") values1);                    break;                case SmsManager.RESULT_ERROR_NULL_PDU:                    Toast.makeText(getBaseContext()Null PDU""                        Toast.LENGTH_SHORT).show();                    break;                case SmsManager.RESULT_ERROR_RADIO_OFF:                    Toast.makeText(getBaseContext()Radio off""                        Toast.LENGTH_SHORT).show();                    break;                default:                    break;            }            context.unregisterReceiver(this);        }    };    SmsManager sms = SmsManager.getDefault();        registerReceiver(sendBroadcastReceiver  new IntentFilter(SENT));        sms.sendTextMessage(phoneNumber null message sentPI deliveredPI);}

当sms发送时屏幕上看都没有问题。根据发送报告sms可以写入content/sms/sent 或者queued中。但是当发送sms时，我点击返回按钮，它可以发送sms但是不能写入content/sms/sent 或者queued中，也不会注销broadcast。
如何处理这个问题呢？

解决方案

你的BroadcastReceiver返回退出界面销毁了吧，总感觉你的写法怪怪的。
