Processing of Android Fragmentation

Causes of fragmentation:

1. Screen size small normal large xlarge xxlarge

2. Screen resolution

3. Horizontal vertical screen

4. System version

Resolution of the Fragment:

1, Dp/sp

The system does not provide a unit that can circumvent partial fragmentation

2. For different versions

The system provides a ANDROID-SUPPORT-V4 package that allows the lower version of the system to achieve a higher version of the functionality

Referencing external open-source projects

3. Solve Horizontal vertical screen

Steps:

Create an XML layout file with the same file name and the same ID for the corresponding control

Resource Type--->layout--->next

Note: Other ways to solve the problem of horizontal vertical screen

Phenomenon: When you switch the screen, the system re-invokes the life cycle

Processing:

Set properties for activity, in the manifest file

Android:configchanges= "Orientation|keyboardhidden|screensize"

Set the orientation of the screen

Some specific applications, such as music players, can set the screen orientation to death

To set the activity's properties in the manifest file

android:screenorientation= "Portrait"

Portrait: Vertical Screen

Landscape: Horizontal Screen
