How call a Loader from a button click?

Question

I use the Loader to load data from my database...
When my activity start... the loader call the asynctask correctly...
but I don't know how to load data just when I click on a button!

if "onCreateLoader", called automatically when activity start, how avoid that?

Solved:
Using FragmentActivity...
used forceload() because the loadInBackgroung didn't work!
used getSupportLoaderManager() because getLoaderManager() didn't work too
both because supposedly the library gives problems!
but... I don't know... I'm not convinced, but...
for now, it works! :P

public void onClick(View v) {

    switch(v.getId()){

    case R.id.button:           

        if(getSupportLoaderManager().getLoader(0) == null){
            getSupportLoaderManager().initLoader(0, null, this).forceLoad();
        }else{
            getSupportLoaderManager().restartLoader(0, null, this).forceLoad();
        }
        break;

    case R.id.another:
        Toast.makeText(this, "another", Toast.LENGTH_SHORT).show();
        break;

    }

}

simply call restartLoader when clicking button :

button.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        getLoaderManager().restartLoader(YOUR_LOADER_ID, null, mYourLoaderCallbacks);
    }
});
