How To Center Linearlayout With 6 Buttons On The Center On Portrait And Landscape Orientation?

What I want to achieve: Center layout with both orientation. Copy

In your onCreate() method first call the method above to get the values and then set the layout params (just a simple example):

getScreenResolution(this); //if you are in a fragment, type getActivity() instead of this
LinearLayout.LayoutParamslayoutParams=newLinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,                             LayoutParams.MATCH_PARENT);
layoutParams.setMargins(width/10, height/15, 0 ,0);   //left, top, right, bottom
yourLinearLayout.setLayoutParams(layoutParams);

Hopefully this helps you to create more general designs in the future :)
