Two small comments:

Naming:
The convention for variable names in Java is camelCase. Your animationframe should instead be animationFrame when going by that rule.

Braces:
It's also convention to place all if-blocks in braces, disregarding whether they have to, or not. This is to decrease the possibility of bugs when changing such blocks and forgetting braces.

if(animationFrame == 3){
    animationFrame = 0;
}

Also the Java-Coding-Standard is 4 spaces indentation. It might be, that the markup for SE broke yours, but either way, your first if-statement is too far in.

anispeed can also be written out: animationSpeed. This should make your code even more clear than it is ;)
