最近看了几款应用的加载进度都是这种风格,感觉还不错,在网上找了一些资料,自己小练兵了一把:
主要运用的开源框架:
/ViewPagerIndicator_library 主要就是标签页切换指示器
/ptr-lib进度条下载地址:https://github.com/liaohuqiu/android-Ultra-Pull-To-Refresh
<强>一、使用方法
布局文件
& lt; & # 63; xml version=" 1.0 " encoding=" utf - 8 " & # 63;比;
& lt; LinearLayout xmlns: android=" http://schemas.android.com/apk/res/android "
android: layout_width=" match_parent "
android: layout_height=" match_parent "
android:背景=" @color/bg_color”
面向android:=按怪薄北?
& lt; in.srain.cube.views.ptr.PtrFrameLayout
xmlns: cube_ptr=" http://schemas.android.com/apk/res-auto "
android: id=癅 + id/material_style_ptr_frame”
android: layout_width=" match_parent "
android: layout_height=" match_parent "
cube_ptr: ptr_duration_to_close=" 100 "
cube_ptr: ptr_duration_to_close_header=" 100 "
cube_ptr: ptr_keep_header_when_refresh=" true "
cube_ptr: ptr_pull_to_fresh=" false "
cube_ptr: ptr_ratio_of_header_height_to_refresh=" 1.2 "
cube_ptr: ptr_resistance=" 1.7 "比;
& lt;列表视图
android: id=癅 + id/article_listview”
android: layout_width=" match_parent "
android: layout_height=" match_parent "
android: cacheColorHint=" # 00000000 "
android:分频器=" @color/线”
android: dividerHeight=" 10 dp/比;
& lt;/in.srain.cube.views.ptr.PtrFrameLayout>
& lt;/LinearLayout>
在java代码中进行控件声明,设置相关参数
mPtrFrameLayout=(PtrFrameLayout) mRootView.findViewById (R.id.material_style_ptr_frame);//头
最后MaterialHeader头=new MaterialHeader (getActivity ());
int[]颜色=getresource () .getIntArray (R.array.google_colors);
header.setColorSchemeColors(颜色);
头。setLayoutParams(新PtrFrameLayout。LayoutParams (1、2));
头。setPadding (0, Utils.dip2px (getActivity (), 15), 0, Utils.dip2px (getActivity (), 10));
header.setPtrFrameLayout (mPtrFrameLayout);
mPtrFrameLayout.setPinContent(真正的);
mPtrFrameLayout.setLoadingMinTime (100);
mPtrFrameLayout.setDurationToCloseHeader (100);
mPtrFrameLayout.setHeaderView(头);
mPtrFrameLayout.addPtrUIHandler(头);
mPtrFrameLayout。setPtrHandler(新PtrHandler () {
@Override
公共布尔checkCanDoRefresh (PtrFrameLayout帧,查看内容,查看标题){
PtrDefaultHandler返回。checkContentCanBePulledDown(框架、article_listview头);
}
@Override
公共空间>
moreView=Finder.inflate (getActivity (), R.layout.loading_more_footer);
moreView.setVisibility (View.GONE);
article_listview=(视图)mRootView.findViewById (R.id.article_listview);
article_listview.addFooterView (moreView);
适配器=new ArticleListAdapter (getActivity ());
article_listview.setAdapter(适配器);
article_listview。setOnItemClickListener(新OnItemClickListener () {
@Override
公共空间onItemClick (AdapterView<& # 63;比;父,查看视图,
int位置,长id) {
篇文章=(文章)adapter.getItem(位置);
目的意图=new意图(getActivity (),
AppBrowserActivity.class);
意图。putExtra (“w_url article.getUrl ());
意图。putExtra (“share_desc article.getTitle ());
意图。putExtra (“share_pic article.getPicUrl ());
startActivity(意图);
}
}）;
article_listview。setOnScrollListener(新OnScrollListener () {
@Override
公共空间onScrollStateChanged (AbsListView看来,int scrollState) {//当不滚动时
如果(scrollState==OnScrollListener.SCROLL_STATE_IDLE) {//判断是否滚动到底部
如果(view.getLastVisiblePosition ()==view.getCount () - 1) {//加载更多功能的代码
moreView.setVisibility (View.VISIBLE);
pageNum + +;
doRequest (pageNum假);
}
}
}
@Override
公共空间onScroll (AbsListView视图,int firstVisibleItem
int visibleItemCount int totalItemCount) {//TODO自动生成方法存根
}
});之前
