 76 |       (except as stated in this section) patent license to make, have made,
 77 |       use, offer to sell, sell, import, and otherwise transfer the Work,

 80 |       Contribution(s) alone or by combination of their Contribution(s)
 81 |       with the Work to which such Contribution(s) was submitted. If You
 82 |       institute patent litigation against any entity (including a
 83 |       cross-claim or counterclaim in a lawsuit) alleging that the Work
 84 |       or a Contribution incorporated within the Work constitutes direct
 85 |       or contributory patent infringement, then any patent licenses
 86 |       granted to You under this License for that Work shall terminate
 87 |       as of the date such litigation is filed.
 88 | 
 89 |    4. Redistribution. You may reproduce and distribute copies of the
 90 |       Work or Derivative Works thereof in any medium, with or without
 91 |       modifications, and in Source or Object form, provided that You
 92 |       meet the following conditions:
 93 | 
 94 |       (a) You must give any other recipients of the Work or
 95 |           Derivative Works a copy of this License; and
 96 | 
 97 |       (b) You must cause any modified files to carry prominent notices
 98 |           stating that You changed the files; and
 99 | 
100 |       (c) You must retain, in the Source form of any Derivative Works
101 |           that You distribute, all copyright, patent, trademark, and
102 |           attribution notices from the Source form of the Work,
103 |           excluding those notices that do not pertain to any part of
104 |           the Derivative Works; and
105 | 
106 |       (d) If the Work includes a "NOTICE" text file as part of its
107 |           distribution, then any Derivative Works that You distribute must
108 |           include a readable copy of the attribution notices contained
109 |           within such NOTICE file, excluding those notices that do not
110 |           pertain to any part of the Derivative Works, in at least one
111 |           of the following places: within a NOTICE text file distributed
112 |           as part of the Derivative Works; within the Source form or
113 |           documentation, if provided along with the Derivative Works; or,
114 |           within a display generated by the Derivative Works, if and
115 |           wherever such third-party notices normally appear. The contents
116 |           of the NOTICE file are for informational purposes only and
117 |           do not modify the License. You may add Your own attribution
118 |           notices within Derivative Works that You distribute, alongside
119 |           or as an addendum to the NOTICE text from the Work, provided
120 |           that such additional attribution notices cannot be construed
121 |           as modifying the License.
122 | 
123 |       You may add Your own copyright statement to Your modifications and
124 |       may provide additional or different license terms and conditions
125 |       for use, reproduction, or distribution of Your modifications, or
126 |       for any such Derivative Works as a whole, provided Your use,
127 |       reproduction, and distribution of the Work otherwise complies with
128 |       the conditions stated in this License.
129 | 
130 |    5. Submission of Contributions. Unless You explicitly state otherwise,
131 |       any Contribution intentionally submitted for inclusion in the Work
132 |       by You to the Licensor shall be under the terms and conditions of
133 |       this License, without any additional terms or conditions.
134 |       Notwithstanding the above, nothing herein shall supersede or modify
135 |       the terms of any separate license agreement you may have executed
136 |       with Licensor regarding such Contributions.
137 | 
138 |    6. Trademarks. This License does not grant permission to use the trade
139 |       names, trademarks, service marks, or product names of the Licensor,
140 |       except as required for reasonable and customary use in describing the
141 |       origin of the Work and reproducing the content of the NOTICE file.
142 | 
143 |    7. Disclaimer of Warranty. Unless required by applicable law or
144 |       agreed to in writing, Licensor provides the Work (and each
145 |       Contributor provides its Contributions) on an "AS IS" BASIS,
146 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147 |       implied, including, without limitation, any warranties or conditions
148 |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149 |       PARTICULAR PURPOSE. You are solely responsible for determining the
150 |       appropriateness of using or redistributing the Work and assume any
151 |       risks associated with Your exercise of permissions under this License.
152 | 
153 |    8. Limitation of Liability. In no event and under no legal theory,
154 |       whether in tort (including negligence), contract, or otherwise,
155 |       unless required by applicable law (such as deliberate and grossly
156 |       negligent acts) or agreed to in writing, shall any Contributor be
157 |       liable to You for damages, including any direct, indirect, special,
158 |       incidental, or consequential damages of any character arising as a
159 |       result of this License or out of the use or inability to use the
160 |       Work (including but not limited to damages for loss of goodwill,
161 |       work stoppage, computer failure or malfunction, or any and all
162 |       other commercial damages or losses), even if such Contributor
163 |       has been advised of the possibility of such damages.
164 | 
165 |    9. Accepting Warranty or Additional Liability. While redistributing
166 |       the Work or Derivative Works thereof, You may choose to offer,
167 |       and charge a fee for, acceptance of support, warranty, indemnity,
168 |       or other liability obligations and/or rights consistent with this
169 |       License. However, in accepting such obligations, You may act only
170 |       on Your own behalf and on Your sole responsibility, not on behalf
171 |       of any other Contributor, and only if You agree to indemnify,
172 |       defend, and hold each Contributor harmless for any liability
173 |       incurred by, or claims asserted against, such Contributor by reason
174 |       of your accepting any such warranty or additional liability.
175 | 
176 |    END OF TERMS AND CONDITIONS
177 | 
178 |    APPENDIX: How to apply the Apache License to your work.
179 |

 1 | Android Multi Item Row ListAdapter
 2 | ==================================
 3 | ### An Easy Way to Make Your ListView's Look Amazing on Tablets
 4 | With the launch of the tablet version of [Umano](http://umanoapp.com) [Android app](https://play.google.com/store/apps/details?id=com.sothree.umano) we decided to open-source another component, which allows you to very quickly make your ListViews and ListActivities look amazing on tablets and phablets by placing multiple items of your ListAdapter in each row in a ListView. Umano Team <3 Open Source.
 5 | 
 6 | As seen in Umano ([http://umanoapp.com](http://umanoapp.com)):
 7 | 
 8 | ![MultiItemRowListAdapter](https://raw.github.com/umano/MultiItemRowListAdapter/master/multiitem.png)
 9 | 
10 | ### Usage
11 | 
12 | All you need to do is wrap your original ListAdapter using a `MultiItemRowListAdapter`:
13 | ```java
14 |     int spacing = (int)getResources().getDimension(R.dimen.spacing);
15 |     int itemsPerRow = getResources().getInteger(R.integer.items_per_row);
16 |     MultiItemRowListAdapter wrapperAdapter = new MultiItemRowListAdapter(this, mAdapter, itemsPerRow, spacing);
17 |     setListAdapter(wrapperAdapter);
18 | ```
19 | As you can see the constructor for `MultiItemRowListAdapter` takes two parameters `itemsPerRow` and `spacing`. The first one is just the number of items from the original adapter to place on each row, and the second one is the cell spacing in pixels between the items. It's really convenient to specify the parameters in xml, so that you can easily vary the number of items per row on different screen orientations and sizes.
20 | res/values/integers.xml - phone portrait (1 items per row)
21 | ```xml
22 | <?xml version="1.0" encoding="utf-8"?>
23 | <resources>
24 |     <integer name="items_per_row">1</integer>
25 | </resources>
26 | ```
27 | res/values-land/integers.xml - phone landscape (2 items per row)
28 | ```xml
29 | <?xml version="1.0" encoding="utf-8"?>
30 | <resources>
31 |     <integer name="items_per_row">2</integer>
32 | </resources>
33 | ```
34 | res/values-sw600/integers.xml - 7' tablet portrait (2 items per row)
35 | ```xml
36 | <?xml version="1.0" encoding="utf-8"?>
37 | <resources>
38 |     <integer name="items_per_row">2</integer>
39 | </resources>
40 | ```
41 | res/values-sw600-land/integers.xml - 7' tablet landscape (3 items per row)
42 | ```xml
43 | <?xml version="1.0" encoding="utf-8"?>
44 | <resources>
45 |     <integer name="items_per_row">3</integer>
46 | </resources>
