Apps Delay function execution and possibility to cancel its execution

[Fr3eZer]

I have a animated loader in my application right now.

public void startLoader() {
Runnable task = new Runnable() {
@Override
public void run() {
lock = true;
loader.setVisibility(View.VISIBLE);
}
};
runOnUiThread(task);
}

public void stopLoader() {
Runnable task = new Runnable() {
@Override
public void run() {
lock = false;
loader.setVisibility(View.GONE);
}
};
runOnUiThread(task);
}
​

Now I want it to work like this:

stopLoader should have an delayed execution of like 1000ms, so it dissapears 1 second after stopLoader is called.
but if the startLoader is called within that 1000ms the stopLoader timer would be cancelled.

What is the best way to implement this?
