This library provides a version of GridLayout that works across all versions of Android 1.5+. As a side effect, this library also includes the lightweight Space as well.
For an introduction to GridLayout/Space, check out the Android Developers Blog post about the benefits and usage of GridLayout and Space.
Compiling this library requires that the build SDK version be set to 3.0 or above. (It uses some more modern methods if they are available.)
This is a copy of the GridLayout from Android, so its usage is very similar. The only difference is that some attributes you will need to use your project's namespace instead of the android namespace:
<com.gridlayout.GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:gridlayout="http://schemas.android.com/apk/res/com.mycompany.myapp"
android:layout_width="match_parent"
android:layout_height="match_parent"
gridlayout:alignmentMode="alignBounds"
gridlayout:columnCount="4"
gridlayout:columnOrderPreserved="false"
gridlayout:useDefaultMargins="true" >
Due to the inability to detect changes in child visibility in older versions of ViewGroup, it is necessary to call GridLayout.notifyChildVisibilityChanged() whenever you change the visibility of a child View of a GridLayout.
If you never change the visibility of children, you don't have to worry about this.
Possible usage: add this project as a submodule to your project and add something like
<dependency>
<groupId>android.gridlayout</groupId>
<artifactId>library</artifactId>
<version>GIT-SNAPSHOT</version>
<type>apklib</type>
<scope>compile</scope>
</dependency>
to your pom.xml file. Note that the android maven plugin must be at least version 3.3.0 to support apklibs.
Currently, including GridLayout from the android compatibility library in a maven project seems not possible. This provides a possible alternative.
