This is a nice way of doing it for any two-dimensional array, assuming you want them in the following order:

[[array[0]-elems], [array[1]elems]...]

public <T> List<T> twoDArrayToList(T[][] twoDArray) {
    List<T> list = new ArrayList<T>();

for(int i=0;i<m;i++)
    for(int j=0;j<n;j++)
        yourList.add(foosArray[i][j]);
