How to iterate through SparseArray?

Question

Is there a way to iterate over Java SparseArray (for Android) ? I used sparsearray to easily get values by index. I could not find one.

Answer 1

Seems I found the solution. I hadn't properly noticed the keyAt(index) function.

So I'll go with something like this:

for(int i = 0; i < sparseArray.size(); i++) {    int key = sparseArray.keyAt(i);    // get the object by the key.    Object obj = sparseArray.get(key); } 

Answer 2

If you don't care about the keys, then valueAt(int) can be used to while iterating through the sparse array to access the values directly.

for(int i = 0, nsize = sparseArray.size(); i < nsize; i++) {     Object obj = sparseArray.valueAt(i); }
