A Custom SwipeRefreshLayout.
##Why? 本来SwipeRefreshLayout已经能够满足大部分的需求了。无奈,产品经理执意要做成下拉过程中,被嵌套的View也要跟随手指的滑动而滑动,并且下拉刷新头可以自定义。
##Feature
- 非侵入式,对原来的ListView、RecyclerView没有任何影响,用法和SwipeRefreshLayout类似。
- 可自定义头部View的样式,调用setHeaderView方法即可
- 支持RecyclerView,ListView,ScrollView,GridView等等。
- 被包含的View(RecyclerView,ListView etc.)可跟随手指的滑动而滑动
默认是跟随手指的滑动而滑动,也可以设置为不跟随:setTargetScrollWithLayout(false) - 回调方法更多
比如:onRefresh() onPullDistance(int distance)和onPullEnable(boolean enable)
开发人员可以根据下拉过程中distance的值做一系列动画。
<net.mobctrl.views.SuperSwipeRefreshLayout
android:id="@+id/swipe_refresh"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</net.mobctrl.views.SuperSwipeRefreshLayout>
swipeRefreshLayout = (SuperSwipeRefreshLayout) findViewById(R.id.swipe_refresh);
swipeRefreshLayout.setHeaderView(createHeaderView());// add headerView
swipeRefreshLayout
.setOnPullRefreshListener(new OnPullRefreshListener() {
@Override
public void onRefresh() {
//TODO 开始刷新
}
@Override
public void onPullDistance(int distance) {
//TODO 下拉距离
}
@Override
public void onPullEnable(boolean enable) {
//TODO 下拉过程中,下拉的距离是否足够出发刷新
}
});
- create your header view
swipeRefreshLayout.setHeaderView(createHeaderView());// add headerView
/**
* create Header View
*/
private View createHeaderView(){
//TODO 创建下拉刷新头部的View样式
}
- setTargetScrollWithLayout(false/true);//default true
swipeRefreshLayout.setTargetScrollWithLayout(true);
- RecyclerView.
- ListView
- SrcollView
- GridView
- etc.
