RecyclerView添加ScrollBar。
<declare-styleable name="RecyclerViewScrollBar">
<attr name="rsbTrackDrawable" format="reference|color"/>
<attr name="rsbThumbDrawable" format="reference|color"/>
<attr name="rsbRadio" format="dimension"/>
<attr name="rsbTrackColor" format="color"/>
<attr name="rsbThumbColor" format="color"/>
<attr name="rsbOrientation" format="enum">
<enum name="horizontal" value="0"/>
<enum name="vertical" value="1"/>
</attr>
</declare-styleable>
| 属性 | 介绍 |
|---|---|
| rsbTrackDrawable | ScrollBar背景 |
| rsbThumbDrawable | ScrollBar滚动条 |
| rsbRadio | ScrollBar背景和滚动条圆角 |
| rsbThumbColor | ScrollBar滚动条颜色 |
| rsbTrackColor | ScrollBar背景颜色 |
| rsbOrientation | ScrollBar方向（水平（默认）、垂直） |
注意：RecyclerViewScrollBar优先使用rsbTrackDrawable、rsbThumbDrawable，没有设置时再根据颜色和角度设置滚动条样式。
- 通过drawable来设置Drawable
<com.sam.lib.recyclerview.scrollbar.RecyclerViewScrollBar
android:id="@+id/mScrollBar"
android:layout_width="100dp"
android:layout_height="5dp"
app:rsbThumbDrawable="@drawable/scroll_bar_thumb"
app:rsbTrackDrawable="@drawable/scroll_bar_track"
/>
- 自定义颜色和角度
<com.sam.lib.recyclerview.scrollbar.RecyclerViewScrollBar
android:id="@+id/mScrollBar2"
android:layout_width="5dp"
android:layout_height="100dp"
app:rsbRadio="5dp"
app:rsbThumbColor="@color/colorAccent"
app:rsbOrientation="vertical"
app:rsbTrackColor="@color/colorPrimaryDark"
/>
- 绑定RecyclerView
RecyclerViewScrollBar scrollBar = findViewById(R.id.scrollBar);
scrollBar.attachToRecyclerView(mRecyclerView);
- 截图
