Library Project including compatibility 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.
|
||
|
|
The accompanying resources must also be included in the application.
|
||
|
|
|
||
|
|
|
||
|
|
USAGE:
|
||
|
|
|
||
|
|
Make sure you use <android.support.v7.widget.GridLayout> in your
|
||
|
|
layouts instead of <GridLayout>.
|
||
|
|
Same for <android.support.v7.widget.Space> instead of <Space>.
|
||
|
|
|
||
|
|
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:
|
||
|
|
|
||
|
|
<?xml version="1.0" encoding="utf-8"?>
|
||
|
|
<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" />
