Fix the position of Toolbar while android verison >= 21

[seasonyuu]

when the android version is Lollipop(or higher),the position of Toolbar in CheeseDetailActivity would be out of the screen....fix this

Change to Build.VERSION.SDK_INT == 21 as this issue is only present at that API level.

@steffandroid I have no other device to test , my mistake

this worked for me

//bug that puts toolbar out of screen
private void fixApi21ToolBarBug(Toolbar toolbar) {
    if(Build.VERSION.SDK_INT!=21) return; //only on api 21
        final int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
        final int result = (resourceId>0) ? getResources().getDimensionPixelSize(resourceId)*2 : 0;
        final CollapsingToolbarLayout.LayoutParams params = 
            (CollapsingToolbarLayout.LayoutParams)toolbar.getLayoutParams();
        params.topMargin -= result;
        toolbar.setLayoutParams(params);
}
