* Added in version 1.4.6 * * @param layout The layout {@link SmoothRefreshLayout} * @param status Current status @see{@link SmoothRefreshLayout#SR_STATUS_INIT}, * {@link SmoothRefreshLayout#SR_STATUS_PREPARE}, * {@link SmoothRefreshLayout#SR_STATUS_REFRESHING}, * {@link SmoothRefreshLayout#SR_STATUS_LOADING_MORE}, * {@link SmoothRefreshLayout#SR_STATUS_COMPLETE}. * @param indicator The indicator {@link IIndicator} */ void onPureScrollPositionChanged(SmoothRefreshLayout layout, byte status, T indicator); } ``` ##### Add custom refresh view - Global static code construction ``` SmoothRefreshLayout.setDefaultCreator(new IRefreshViewCreator() { @Override public void createHeader(SmoothRefreshLayout layout) { ClassicHeader header = new ClassicHeader(layout.getContext()); layout.setHeaderView(header); } @Override public void createFooter(SmoothRefreshLayout layout) { ClassicFooter footer = new ClassicFooter(layout.getContext()); layout.setFooterView(footer); } }); ``` - Use Java code to config ``` ClassicHeader header = new ClassicHeader(mRefreshLayout.getContext()); mRefreshLayout.setHeaderView(header); ClassicFooter footer = new ClassicFooter(mRefreshLayout.getContext()); mRefreshLayout.setFooterView(footer); ``` - Please write directly to the Xml file,SmoothRefreshLayout will find the view that impl the IRefreshView interface to added inside. #### Impl the QQ pull down damping effect(Custom offset calculator) ``` mRefreshLayout.setIndicatorOffsetCalculator(new IIndicator.IOffsetCalculator() { @Override public float calculate(@IIndicator.MovingStatus int status, int currentPos, float offset) { if (status == IIndicator.MOVING_HEADER) { if (offset < 0) { return offset; } return (float) Math.pow(Math.pow(currentPos / 2, 1.28d) + offset, 1 / 1.28d) * 2 - currentPos; } else if (status == IIndicator.MOVING_FOOTER) { if (offset > 0) { return offset; } return -((float) Math.pow(Math.pow(currentPos / 2, 1.28d) - offset, 1 / 1.28d) * 2 - currentPos); } else { if (offset > 0) { return (float) Math.pow(offset, 1 / 1.28d) * 2; } else if (offset < 0) { return -(float) Math.pow(-offset, 1 / 1.28d) * 2; } else { return offset; } } } }); ``` #### Xml attr ##### SmoothRefreshLayout |Name|Format|Desc| |:---:|:---:|:---:| |sr_content|reference|Specifies the resource ID
