When using setOnGroupClickListener method report an error “cannot find symbol”，
I try to use setOnGroupClickListener to register sublist click event listener to list control，But an error is reported during compilation
error report:
vendor/proprietary/modem/ModemTestBox/src/com/xiaomi/mtb/activity/MtbNvAutoCheckList1Activity.java:142: error: cannot find symbol

i have a cartactivity and cartadapter, in cartadapter i add increment and decrement for each stuff, and i sum it in total price and total weight and send it to activity ( it worked by passing textview activity from cartactivity to adapteractivity ) and now i want to get seperated quantity for each item to send to database with format Example if item is ( Wallet, Bag, Shoes ) then quanitity that will send to database like this ( 2, 3, 3) 2 represent for wallet and (,) for seperating item quantity, 3 represent bag, and 3 represent shoes. i don't know how to take each quantity and send it in a format like that
have a look on my adapter

to make sum of total prices i used this code
public int totalCart(ArrayList<MadolCart> items, String name){
for(int i = 0 ; i < items.size(); i++) {
totalname = items.get(i).getNamacart();
if (totalname.equals(name)){
totalharga += items.get(i).getHarga();
}
}
return totalharga;
}
i put summing code in a method, and call the method on if button + is clicked
if button - is clicked it will call this method
public int kurangtotalcart(ArrayList<MadolCart> items, String name){
for(int i = 0 ; i < items.size(); i++) {
totalname = items.get(i).getNamacart();
if (totalname.equals(name)){
totalharga -= items.get(i).getHarga();
}
}
return totalharga;
}
and now idk how to get seperated quanitity for each position / item in recycler view then send it to activity as format ( 1, 2, 3) (,) mean a seperator for each item
How to get value seperated quantity from recycler view item position?
SOLVED
public String getSeperatedquantity(List<MadolCart> quantity){
String kus = "";
for (int i = 0; i < quantity.size(); i++){
kus += quantity.get(i).getQuantity() + ", ";
}
return kus;
}
I found the solution by adding this:
public String getSeperatedquantity(List<MadolCart> quantity){
String kus = "";
for (int i = 0; i < quantity.size(); i++){
kus += quantity.get(i).getQuantity() + ", ";
}
return kus;
}
I'm working on an Android Security Lab. One of the tasks is : Get a list of all algorithms supported on the device. The hints are: Get the providers, get the services and then get the list of algorithms.
I have the following code that does that but I don't understand the part that gets the services and the algorithms. I'm actually discovering Java in the same time as Android ...
Can anyone help me to understand how it works please ?

Security is the class that manages the security of the app. It contains array of providers that have all the security services. Within the provider they contains array of algorithm that the system use. In the first part of the provider where
if (k.startsWith("Alg.Alias."))
k = k.substring(10);
it gets the service with keyword "Alg.Alias."
I have some trouble in getting Tcp connection log of all apps. Basically, I just read the log file "/proc/Pid/net/tcp" as used here:
http://code.google.com/p/iptableslog/source/browse/src/com/googlecode/networklog/NetStat.java?r=60cb640ac27f8b4fb06f11d9d81c94591a531862
But all the destination ip address are 0.0.0.0, though some apps are connecting to Internet.
Here is my source code:

And I also added the permission "uses-permission android:name="android.permission.INTERNET".
Could someone kindly point out where I did wrong?
Oh, when I check this log "/proc/Pid/net/tcp6", I found the correct destination ip address. It seems that the connection type is tcp6 instead of tcp.
I'm facing a particular problem while parsing xml so the parser works fine until it encouters <Url/> tag which contains no value, I already made the test il my code :
static final String ImageHotel = "Url";
...
else if (name.equalsIgnoreCase("ImageHotel")){
message.setHotelImage(property.getFirstChild().getNodeValue());
if (!marchand.getImgHtlUrl().equalsIgnoreCase("")){
message.setHotelImageLink(new URL(marchand.getImgHtlUrl() + property.getFirstChild().getNodeValue()));
}else{
message.setHotelImageLink(new URL("http://localhost/noimage.jpg"));
}
}
This keep throwing error even when i tried to bypass by surrounding with try/catch..
any help is welcome
thanks.
Houssem.
I have reference to parse this file try to add your own data and get tag value....

I told you that surrounding with try/catch did not work, so, now it does, because i had to track the NullPointerException instead of simple Exception, like this :
try{
message.setHotelImage(property.getFirstChild().getNodeValue());
}catch(NullPointerException nEx){
marchand.setImgHtlUrl("");
}
thank you guys and sorry for this alert ;)
