How it looks like : XHDPI PSD on Nexus 4 Screen?

Dear Android Developers,

as far as I know, Android has 4 different types of screen resolution :

now, Google Nexus 4 has screen resolution : 768 x 1280, which I assume this categorised as XHDPI model. *please correct me if I'm wrong.

now take a look at my picture...

enter image description here

so, if I put XHDPI size (red area) on top of Nexus 4 screen (grey area) you'll see what I see.

now, if I have 4 white boxes horizontally and 6 white boxes vertically on red area (PSD design). what it looks like on Nexus 4 screen resolution?

can we programatically add more boxes (blue boxes) to fill the empty space? or Android will automatically stretch that red area until covers all grey area? which means all of white boxes will be stretched too...

that's all I need to know... thanks.

You should watch Roman Nurik's Design Bytes: Density-Independent Pixels video.

First, stop thinking in pixels. Think of devices using density-independent pixels. The buckets that Android uses (ldpi, mdpi, etc.) are not measured in pixels; they are measured in dots-per-inch (DPI).

Those buckets are actually:

  • LDPI: 120 DPI
  • MDPI: 160 DPI
  • HDPI: 240 DPI
  • XHDPI: 320 DPI

The Nexus 4 has a DPI of precisely 320.

Screen size and Screen DPI are different things. Check https://developer.android.com/guide/practices/screens_support.html
