Java – slidingmenu width incorrect

I use jfeinstein1's slidingmenu library. In my project I want to slide the slide menu out to about 3 / 4 of the screen width According to the documentation, this should be available

setBehindWidth()
setBehindOffset()

But for now, the menu slides all the way to the right and covers the entire screen Here is my code:

public void setupMenu() {
    setContentView(R.layout.activity_base);
    menu = new SlidingMenu(this);
    menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
    menu.setBehindWidth(100);
    menu.setBehindOffset(100);
    menu.attachToActivity(this,SlidingMenu.SLIDING_CONTENT);
    menu.setMenu(R.layout.sliding_menu);
}

Thank you in advance

Solution

I have a menu that slides from the right, just call:

getSlidingMenu().setMode(SlidingMenu.RIGHT);
getSlidingMenu().setBehindOffset(100);

Hope to help
