Answer 1

to get the width you should do this :

Display display = getWindowManager().getDefaultDisplay();
double deviceWidth;
if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.HONEYCOMB_MR1)
            deviceWidth= display.getWidth();
        else {
            display.getSize(size);
            deviceWidth=size.x;
        }
