3 | The development of this control library is intended to enhance the performance and experience of Android native controls.
4 |
5 | 
6 |
7 | # Effect
8 | The overstretched effect of the top picture added is the overstretching effect of the picture imitated by IOS Appstore.
9 |
10 | 
11 |
12 | * Extend RecycleView, retaining its original features
13 | * According to the rolling item of RecycleView, it dynamically adjusts the top position of each item and scale value of head, and does not trigger requestLayout.
14 | * Head has handled all kinds of extreme situations that have been deployed to ensure that head will not reveal only half of them.
15 | * The fast throw motion of RecycleView is processed to ensure that the position of head can be normal when fling to head.
16 |
17 |
18 |
19 | # Integrate
20 | You need to integrate the V4 and V7 libraries, and the effect libraries here
21 |
22 | implementation 'com.chw.android:widget:3.0.3'
23 | implementation 'com.android.support:support-v4:27.1.1'
24 | implementation 'com.android.support:recyclerview-v7:27.1.1'
25 |
26 | # Use
27 |
28 | It is very simple to use, change the RecycleView to WeRecycleView, and set the sliding mode.
29 |
30 | mRecycleView.setScrollMode(WeRecycleView.SCROLL_SCALE_HEAD);
31 | mRecycleView.setMaxScale(4f);

3 | 开发这个控件库是为了致力于提升android原生控件的一些性能及体验
4 |
5 | 
6 |
7 | # 效果
8 | 这次添加的顶部图片过度拉伸效果是仿ios的appstore中的图片过度拉伸效果。
9 |
10 | 
11 |
12 | * 继承RecycleView，保留RecycleView原本的特性
13 | * 根据RecycleView的滚动item时动态调整各item的top位置及head的scale值，不触发requestLayout。
14 | * 处理了head收起展开的各种极端情况，确保head不会只露出半个
15 | * 处理了RecycleView的快速抛动情况，确保fling到head时head的位置能正常
16 |
17 |
18 |
19 | # 集成
20 | 需要集成v4和v7两个库，以及这里的效果库

23 | implementation 'com.android.support:support-v4:27.1.1'
24 | implementation 'com.android.support:recyclerview-v7:27.1.1'
25 |
26 | # 使用
27 |
28 | 使用起来十分简单，将RecycleView换成WeRecycleView即可，设置滑动模式
29 |
30 | mRecycleView.setScrollMode(WeRecycleView.SCROLL_SCALE_HEAD);
31 | mRecycleView.setMaxScale(4f);
