13 | ## Include SpringRecyclerView to Your Project
14 |
15 | With gradle:
16 |
17 | ```groovy
18 | dependencies {
19 | compile 'com.gjiazhe:SpringRecyclerView:1.0'
20 | }
21 | ```
22 | ## Use SpringRecyclerView in Layout Files
23 |
24 | ```xml
25 |
33 | ```
34 |
35 | ## Description of Attributes
36 | | Attributes | Format | Default | Description |
37 | | :-----------------------------: | :-----: | :-----: | :--------------------------------------: |
38 | | srv_enableSpringEffectWhenDrag | boolean | true | Whether the spring effect is enabled when we drag the recyclerView to overScroll. |
39 | | srv_enableSpringEffectWhenFling | boolean | true | Whether the spring effect is enabled when we fling the recyclerView to overScroll. |
40 | | srv_releaseBackAnimDuration | int | 300 | Duration of the rebound animation after we release the recyclerView. In millisecond. |
41 | | srv_flingBackAnimDuration | int | 300 | Duration of the rebound animation after we fling the recyclerView. In millisecond. |
42 |
43 | You can set these attributes in the layout file, or in the java code:
44 |
45 | ```java
46 | SpringRecyclerView springRecyclerView = (SpringRecyclerView)findViewById(R.id.spring_recycler_view);
47 | springRecyclerView.setEnableSpringEffectWhenDrag(true);
48 | springRecyclerView.setEnableSpringEffectWhenFling(true);
49 | springRecyclerView.setReleaseBackAnimDuration(300);
50 | springRecyclerView.setFlingBackAnimDuration(300);
51 | ```
