Size and position of GLSurfaceView

Actually I have project in which I'm using GLSurfaceView. At this moment this component is placed as main control on whole screen. In this configuration I'm able proper handling drawing functionality.

In next step I want to change size and position of GLSurfaceView. I want to place it in the center of the screen and set width and hight to exact phicical dimmension for example 20mm x 20mm.

Do you have any advices or hints how should I start to introduce this kind of changes to GLSurfaceView?

You need to set gravity to the parent element like Gravity.CENTER. For example if it's LinearLayout then call linearLayout.setGravity(Gravity.CENTER).

Set width and hight to exact phicical dimmension for example 20mm x 20mm

To calculate size from mm to pixels use:

float mmInPx = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_MM, 20, 
                getResources().getDisplayMetrics());

And to set size for GLSurfaceView use LayoutParams:

ViewGroup.LayoutParams layoutParams=glSurfaceView.getLayoutParams();
layoutParams.width=mmInPx;
layoutParams.height=mmInPx;
glSurfaceView.setLayoutParams(layoutParams);
