Library Project including GridLayout.

This can be used by an Android project to provide access to GridLayout on applications running on API 7+

There is technically no source, but the src folder is necessary to ensure that the build system works. The content is actually located in libs/android-support-v7-gridlayout.jar

USAGE:

Make sure you use <android.support.v7.widget.GridLayout> in your layouts instead of . Same for <android.support.v7.widget.Space> instead of .

Additionally, all of GridLayout's attributes should be put in the namespace of the app, as those attributes have been redefined in the library so that it can run on older platforms that don't offer those attributes in their namespace.

To know which attributes need the application namespace, look at the two declare-styleable declared in res/values/attrs.xml

For instance:

<android.support.v7.widget.GridLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" <==== the namespace used for the library project android:layout_width="match_parent" android:layout_height="match_parent" app:columnCount="6" > <===== notice how we're using app:columnCount here, not android:columnCount!

<Button
    android:id="@+id/button1"
    app:layout_column="1"                            <=== again, note the app: namespace
    app:layout_columnSpan="2"
    app:layout_gravity="left"
    app:layout_row="1"
    android:text="Button" />

<CheckBox
    android:id="@+id/checkBox1"
    app:layout_column="4"
    app:layout_gravity="left"
    app:layout_row="2"
    android:text="CheckBox" />

<Button
    android:id="@+id/button2"
    app:layout_column="5"
    app:layout_gravity="left"
    app:layout_row="3"
    android:text="Button" />

<android.support.v7.widget.Space                    <=== space widgets also need the full support package path
    android:layout_width="21dp"                     <=== use the android namespace for width, height etc -- only use app: for the grid layout library's new resources
    android:layout_height="1dp"
    app:layout_column="0"
    app:layout_gravity="fill_horizontal"
    app:layout_row="0" />
