1 | 6Wunderkinder SlidingLayer for Android
2 | =============================
3 | This repository hosts a library that provides an easy way to include an autonomous layer/view that slides from any side of your screen and which is fully gesture ready, the same way as our detail view in Wunderlist 2 does.
4 | This pattern can also be seen in Google+’s notification center, Google Maps, Google Music, Contacts app in Lollipop, Basecamp’s detail view, among others.
5 |
6 | If you want to see how it works you can have a look to our [video](http://www.youtube.com/watch?v=162oD0XPM40) or directly download from [Google Play](https://play.google.com/store/apps/details?id=com.slidinglayersample) it to test in on your device.
7 |
8 |
9 | Implementation setup
10 | ------------------------------
11 | As easy as to draw a green droid yourself, just grab it in your build gradle:
12 |
13 | ```gradle
14 | compile 'com.wunderlist:sliding-layer:1.2.5'
15 | ```
16 |
17 | or directly add it as a submodule inside of your project.
18 |
19 |
20 | Integration
21 | ---------------
22 | Due to simplicity and lightness, this container is currently based on a FrameLayout. Just treat it as you would with other container: Place it in any of your XML layout files or drag it from the Custom Components panel. Additionally you can add this view programmatically.
23 | In the following example the same layout will be added by using the two mentioned ways.
24 |
25 |
26 | XML
27 | -----
28 | ```xml
29 |
40 |
41 | …
42 | …
43 |
44 | ```
45 |
46 | Properties:
47 | * `shadowDrawable` - a reference to the resource drawable used to paint the shadow of the container
48 | * `shadowSize` - a reference to the dimension of the desired size of the given shadow
49 | * `offsetDistance` - a reference to the dimension of the desired size for the layer to offset in the screen in order for it to be directly swipable to open
50 | * `previewOffsetDistance` - a reference to the dimension of the desired size of the preview mode. When opening the layer in this state, it will only show this amount of the layer. Preview mode can be open by tapping the layer, dragging or programmatically by calling `openPreview(boolean smoothAnimation)`.
51 | * `stickTo` - an enum that determines to where the container should stick to. ‘left’ sticks the container to the left side of the screen. ‘right’ sticks the container to the right side of the screen, and so on with ‘top‘ and ‘bottom‘ states. Default is ‘right’.
52 | * `changeStateOnTap` - a boolean that enables/disables the action to change the state of the layer -open, preview or close- by tapping on an empty space of the container. Default value is true.
53 |
54 |
55 | Java
56 | -----
57 | ```java
58 | public class SlidingLayerExampleActivity extends Activity {
59 |
60 | @Override
61 | public void onCreate(Bundle savedInstanceState) {
62 | super.onCreate(savedInstanceState);
63 | setContentView(R.layout.main_view);
64 |
65 | SlidingLayer slidingLayer = (SlidingLayer) findViewById(R.id.slidingLayer1);
66 |
67 | slidingLayer.setShadowDrawable(R.drawable.sidebar_shadow);
68 | slidingLayer.setShadowSizeRes(R.dimen.shadow_size);
69 | slidingLayer.setOffsetDistanceRes(R.dimen.offset_distance);
70 | slidingLayer.setPreviewOffsetDistanceRes(R.dimen.preview_offset_distance);
71 | slidingLayer.setStickTo(SlidingLayer.STICK_TO_LEFT);
72 | slidingLayer.setChangeStateOnTap(false);
73 |
74 | slidingLayer.addView(new Button(this));
75 | ...
76 | }
77 | }
78 | ```

136 | the terms of any separate license agreement you may have executed
137 | with Licensor regarding such Contributions.
138 |
139 | 6. Trademarks. This License does not grant permission to use the trade
140 | names, trademarks, service marks, or product names of the Licensor,
141 | except as required for reasonable and customary use in describing the

157 | negligent acts) or agreed to in writing, shall any Contributor be
158 | liable to You for damages, including any direct, indirect, special,
159 | incidental, or consequential damages of any character arising as a
160 | result of this License or out of the use or inability to use the
161 | Work (including but not limited to damages for loss of goodwill,
162 | work stoppage, computer failure or malfunction, or any and all
163 | other commercial damages or losses), even if such Contributor
164 | has been advised of the possibility of such damages.
165 |
166 | 9. Accepting Warranty or Additional Liability. While redistributing
167 | the Work or Derivative Works thereof, You may choose to offer,
168 | and charge a fee for, acceptance of support, warranty, indemnity,
169 | or other liability obligations and/or rights consistent with this
170 | License. However, in accepting such obligations, You may act only
171 | on Your own behalf and on Your sole responsibility, not on behalf
172 | of any other Contributor, and only if You agree to indemnify,
173 | defend, and hold each Contributor harmless for any liability
174 | incurred by, or claims asserted against, such Contributor by reason
175 | of your accepting any such warranty or additional liability.
