1 Library Project including 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

11 USAGE:
12
13 Make sure you use <android.support.v7.widget.GridLayout> in your
14 layouts instead of <GridLayout>.
15 Same for <android.support.v7.widget.Space> instead of <Space>.
16
17 Additionally, all of GridLayout's attributes should be put in the
18 namespace of the app, as those attributes have been redefined in
19 the library so that it can run on older platforms that don't offer
20 those attributes in their namespace.
21
22 To know which attributes need the application namespace, look at
23 the two declare-styleable declared in res/values/attrs.xml

27 For instance:
28
29 <?xml version="1.0" encoding="utf-8"?>
30 <android.support.v7.widget.GridLayout
31 xmlns:android="http://schemas.android.com/apk/res/android"
32 xmlns:app="http://schemas.android.com/apk/res-auto" <==== the namespace used for the library project
33 android:layout_width="match_parent"
34 android:layout_height="match_parent"
35 app:columnCount="6" > <===== notice how we're using app:columnCount here, not android:columnCount!
36
37 <Button
38 android:id="@+id/button1"
39 app:layout_column="1" <=== again, note the app: namespace
40 app:layout_columnSpan="2"
41 app:layout_gravity="left"
42 app:layout_row="1"
43 android:text="Button" />
44
45 <CheckBox
46 android:id="@+id/checkBox1"
47 app:layout_column="4"
48 app:layout_gravity="left"
49 app:layout_row="2"
50 android:text="CheckBox" />
51
52 <Button
53 android:id="@+id/button2"
54 app:layout_column="5"
55 app:layout_gravity="left"
56 app:layout_row="3"
57 android:text="Button" />
58
59 <android.support.v7.widget.Space <=== space widgets also need the full support package path
60 android:layout_width="21dp" <=== use the android namespace for width, height etc -- only use app: for the grid layout library's new resources
61 android:layout_height="1dp"
62 app:layout_column="0"
63 app:layout_gravity="fill_horizontal"
64 app:layout_row="0" />
