我有一个 android 应用程序，它发送多条消息并调用点击事件。问题是
我有两个点击事件。在第二次点击事件中，代码运行完美，但在第一次点击事件中，相同的代码不起作用（即它不发送任何消息）。这可能看起来很愚蠢，但我无法找出错误。请告诉我如何解决这个问题。
如果需要任何其他信息，请通知我。
我的代码是：

当我使用此代码处理上述错误时（您是否错过了对 unregisterReceiver() 的调用？）使用此代码：
private BroadcastReceiver sendBroadcastReceiver;
private BroadcastReceiver deliveryBroadcastReceiver;
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
sendBroadcastReceiver = new BroadcastReceiver()
{
public void onReceive(Context arg0, Intent arg1)
{
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS Sent", Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(), "Generic failure", Toast.LENGTH_SHORT).show();
break;

break;
case SmsManager.RESULT_ERROR_RADIO_OFF:

}

break;
}
}
};
registerReceiver(deliveryBroadcastReceiver, new IntentFilter(DELIVERED));
registerReceiver(sendBroadcastReceiver , new IntentFilter(SENT));

sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
}
@Override

unregisterReceiver(sendBroadcastReceiver);
unregisterReceiver(deliveryBroadcastReceiver);

错误日志 更改代码后，将 multipleSMS 函数替换为新代码的 sendSMS 函数。
