I'm new to Java and Android so bear with me.
I have one arrayList of strings that i am filling on the main UI.
I have another thread that is sending one by one the strings of the arrayList through a socket, and after sending each one it erases it from the list.
So basically it's a FIFO , with two different threads accessing the same arrayList.
How can I make this reading and writing on the same list, thread safe? Because I read that I have to, thus preventing future errors.
My first thought was creating a synchronized method to access the arrayList.
This is the method I created to access the ArrayList by both threads.
public synchronized String accessArrayList(boolean add, boolean get, String utt)
{
if(add){
mStrings.add(utt);
return null;
}
else if(get){
return mStrings.get(0);
}
else{
mStringsUttComm.remove(0);
return null;
}
}
The main thread just add's strings to this list.
The second thread does this :
Runnable runner = new Runnable() {
public void run() {
while(!mString.isEmpty()){
//socket sends string
sc.actionPerformed(accessArrayList(false, true, null));
//erase from list
accessArrayList(false, false, null);
}
}
};
Is this correct? Because I am new to eclipse and I can't find a way to confirm that one thread doesn't call accessArrayList if the other one is using it.
Thank you for your time.
