Android: Specify array size?

Question

anyone knows how to specify array size?

public String[] videoNames = {""}

the array above can accomodate only one value. i want to extend how many values this array can accomodate.

Answer 1

You should write it like this.

String[] videoNames = new String[5]; // create videoNames array with length = 5
for(int i=0;i<videoNames.length();i++)
{
   // IMPORTANT : for each videoName, instantiate as new String.
   videoNames[i] = new String(""); 
}

Answer 2

if you want dynamic size then use arraylist. something like:

public ArrayList<String> myList = new ArrayList<String>();

...

myList.add("blah");

...

for(int i = 0, l = myList.size(); i < l; i++) {
  // do stuff with array items
  Log.d("myapp", "item: " + myList.get(i));
}
