Android Programming: Resizing UI elements proportionally

[vibeit]

Hi,

 

I need help to resize UI elements (Spinner and the orange icons) proportionally based on the screen size because the size of the UI elements are the same on both screens. Here's the code for resizing. I attached pictures of the 2 screens. I want the smaller phone to adjust the icons proportionally like the bigger tablet.

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
final int width = size.x;
final int height = size.y;

int icon_dim_width = (int)PX_DP(height/10); //<- does not work

//I need a code here that will adjust the size based on the screen size.
float cheight = (0.75f * height) * 100;
float banner_height = height/5;

icon_bookmark.setMinimumWidth(icon_dim_width);
icon_bookmark.setMinimumWidth(icon_dim_width);
icon_bookmark.setMinimumHeight(icon_dim_width);
icon_bookmark.setMaxHeight(icon_dim_width);

icon_chapters.setMinimumWidth(icon_dim_width);
icon_chapters.setMinimumWidth(icon_dim_width);
icon_chapters.setMinimumHeight(icon_dim_width);
icon_chapters.setMaxHeight(icon_dim_width);

icon_exit.setMinimumWidth(icon_dim_width);
icon_exit.setMinimumWidth(icon_dim_width);
icon_exit.setMinimumHeight(icon_dim_width);
icon_exit.setMaxHeight(icon_dim_width);
