1 Library Project including compatibility GridLayout.
2 
3 This can be used by an Android project to provide
4 access to GridLayout on applications running on API 7+.
5 
6 There is technically no source, but the src folder is necessary
7 to ensure that the build system works.  The content is actually
8 located in libs/android-support-v7-gridlayout.jar.
9 The accompanying resources must also be included in the application.
10 
11 
12 USAGE:
13 
14 Make sure you use <android.support.v7.widget.GridLayout> in your
15 layouts instead of <GridLayout>.
16 Same for <android.support.v7.widget.Space> instead of <Space>.
17 
18 Additionally, all of GridLayout's attributes should be put in the
19 namespace of the app, as those attributes have been redefined in
20 the library so that it can run on older platforms that don't offer
21 those attributes in their namespace.
22 
23 To know which attributes need the application namespace, look at
24 the two declare-styleable declared in res/values/attrs.xml
25 
26 
27 
28 For instance:
29 
30 <?xml version="1.0" encoding="utf-8"?>
31 <android.support.v7.widget.GridLayout
32     xmlns:android="http://schemas.android.com/apk/res/android"
33     xmlns:app="http://schemas.android.com/apk/res-auto"  <==== the namespace used for the library project
34     android:layout_width="match_parent"
35     android:layout_height="match_parent"
36     app:columnCount="6" >                                <===== notice how we're using app:columnCount here, not android:columnCount!
37 
38     <Button
39         android:id="@+id/button1"
40         app:layout_column="1"                            <=== again, note the app: namespace
41         app:layout_columnSpan="2"
42         app:layout_gravity="left"
43         app:layout_row="1"
44         android:text="Button" />
45 
46     <CheckBox
47         android:id="@+id/checkBox1"
48         app:layout_column="4"
49         app:layout_gravity="left"
50         app:layout_row="2"
51         android:text="CheckBox" />
52 
53     <Button
54         android:id="@+id/button2"
55         app:layout_column="5"
56         app:layout_gravity="left"
57         app:layout_row="3"
58         android:text="Button" />
59 
60     <android.support.v7.widget.Space                    <=== space widgets also need the full support package path
61         android:layout_width="21dp"                     <=== use the android namespace for width, height etc -- only use app: for the grid layout library's new resources
62         android:layout_height="1dp"
63         app:layout_column="0"
64         app:layout_gravity="fill_horizontal"
65         app:layout_row="0" />
