最近看了几款APP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tab页切换指示器
/ptr-lib 进度条 下载地址:https://github.com/liaohuqiu/android-Ultra-Pull-To-Refresh
一、使用方法
布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/bg_color"
android:orientation="vertical" >
<in.srain.cube.views.ptr.PtrFrameLayout
xmlns:cube_ptr="http://schemas.android.com/apk/res-auto"
android:id="@+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" >
<ListView
android:id="@+id/article_listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:cacheColorHint="#00000000"
android:divider="@color/line"
android:dividerHeight="10dp" />
</in.srain.cube.views.ptr.PtrFrameLayout>
</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);
// header
final MaterialHeader header = new MaterialHeader(getActivity());
int[] colors = getResources().getIntArray(R.array.google_colors);
header.setColorSchemeColors(colors);
header.setLayoutParams(new PtrFrameLayout.LayoutParams(-1, -2));
header.setPadding(0, Utils.dip2px(getActivity(), 15), 0, Utils.dip2px(getActivity(), 10));
header.setPtrFrameLayout(mPtrFrameLayout);
mPtrFrameLayout.setPinContent(true);
mPtrFrameLayout.setLoadingMinTime(100);
mPtrFrameLayout.setDurationToCloseHeader(100);
mPtrFrameLayout.setHeaderView(header);
mPtrFrameLayout.addPtrUIHandler(header);
mPtrFrameLayout.setPtrHandler(new PtrHandler() {
@Override
public boolean checkCanDoRefresh(PtrFrameLayout frame, View content, View header) {
return PtrDefaultHandler.checkContentCanBePulledDown(frame, article_listview, header);
}
@Override
public void onRefreshBegin(final PtrFrameLayout frame) {
pageNum = 1;
doRequest(pageNum, true);
}
});
手动刷新:mPtrFrameLayout.autoRefresh();
结束刷新:mPtrFrameLayout.refreshComplete();
mPtrFrameLayout.setPinContent(true);这里可以根据个人喜好设置true或者false,true则在刷新的时候,将布局里的内容固定不动,false则是在刷新的时候进度条会将布局内容挤下来。
监听ListView是否滑动到底部,如果到达底部,则显示底部加载更多的进度条。
moreView = Finder.inflate(getActivity(), R.layout.loading_more_footer);
moreView.setVisibility(View.GONE);
article_listview = (ListView) mRootView.findViewById(R.id.article_listview);
article_listview.addFooterView(moreView);
adapter = new ArticleListAdapter(getActivity());
article_listview.setAdapter(adapter);
article_listview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Article article = (Article) adapter.getItem(position);
Intent intent = new Intent(getActivity(),
AppBrowserActivity.class);
intent.putExtra("w_url", article.getUrl());
intent.putExtra("share_desc", article.getTitle());
intent.putExtra("share_pic", article.getPicUrl());
startActivity(intent);
}
});
article_listview.setOnScrollListener(new OnScrollListener(){
@Override
public void onScrollStateChanged(AbsListView view, int scrollState){
// 当不滚动时
if (scrollState == OnScrollListener.SCROLL_STATE_IDLE) {
// 判断是否滚动到底部
if (view.getLastVisiblePosition() == view.getCount() - 1) {
//加载更多功能的代码
moreView.setVisibility(View.VISIBLE);
pageNum++;
doRequest(pageNum, false);
}
}
}
@Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
// TODO Auto-generated method stub
}
});
