问题
This is my first time making an app with XML layouts. In the past I have always dynamically generated my layouts at runtime, so don't worry, I am NOT an Android newbie. Still, this is my first time with static layouts. So what's this message all about?
[2010-09-22 20:43:23 - Rockport] 'default' is not a best match for any device/locale combination.
[2010-09-22 20:43:23 - Rockport] Displaying it with 'Locale Language ___Region __, Normal Screen, Short screen aspect ratio, Landscape Orientation, No Dock, Day time, Medium Density, Finger-based touchscreen, Soft keyboard, Qwerty keybard, Trackball navigation, Screen resolution 480x320'
It gets printed to my Eclipse console every time I open up one of the layouts in the layout/ folder. If I open the layout from any other folder, such as layout-land/ then I get no message. Is it just the graphical layout editor saying, "Here's how I'm going to display things for you?" Can I safely ignore it?
回答1:
No don't ignore it, it does mean something.
What it is saying is that Eclipse has found a layout which it believes is more accurate and is switching to it.
So for example if you have a default layout and a low density layout, it will switch to the low density layout. Any changes you make to the layout will be in the low density code not in the default code.
I don't know how to switch back, which is getting very annoying, apart from closing the xml and opening up the correct one.
If anyone knows how to switch, and yes I have tried changing the settings at the top of the editor between low density and medium density devices, please tell me. Thanks.

Do not run the project with the file XML selected. Clean build the project, Only click in the project name, after select run, you won't have this error

I had this problem and for me just solved by selecting my projects "MainActivity" from dropdown menu "Associated activity or fragment providing context" in the graphical view of my layout.
