Practical development problem summary (Interface Design) -- how Android applications adapt to mobile phones with multiple resolutions

PrefaceAndroidDiverse mobile phone resolutions,In this way, our applications must be adapted to devices with multiple resolutions..

There are three main considerations for applications:

1)Interface Configuration

 Create mobile phone interface files based on different resolutions

 Example:

 InResCreateLayout-800x480

Layout-480x320

 Create interface files in folders with different resolutions

 

2)Image Configuration

 The aspect ratio of the interface varies with different resolutions. Images of different specifications are required.

 InDrawable-hdpi,Drawable-ldpi,Drawable-mdpiPlace images of different resolutions

 

3) Dynamically implemented interface and style settings

Different resolutions, UI font sizes, fonts, and other styles need to be dynamically generated, and configuration information for different resolutions needs to be saved to the application.

 

For exampleResCreateValues-480x320 values-800x400

In the created folder, createString. xml

<Dimen name = "text_size"> 30px </dimen>

 

InProgramDirectly callingR. dimen. text_size
