Android(安卓)下拉刷新控件SwipeRefreshLayout结合WebView使用
SwipeRefreshLayout 是谷歌官方下拉刷新控件,4.0以下的版本需要用到 android-support-v4.jar包才能用到
android-support-v4.jar 包下载地址:http://download.csdn.net/detail/h7870181/7784247
官网API地址:https://developer.android.com/reference/android/support/v4/widget/SwipeRefreshLayout.html
GitHub Demo下载地址: https://github.com/stormzhang/SwipeRefreshLayoutDemo
SwipeRefreshLayout 使用起来是非常简单的,只需要在可以滑动的控件外层添加即可,如:WebView、ListView和ScroolView.
<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <android.support.v4.widget.SwipeRefreshLayout android:id="@+id/swipe_container" android:layout_width="match_parent" android:layout_height="match_parent" > <WebView android:id="@+id/webview" android:layout_width="match_parent" android:layout_height="match_parent"/> </android.support.v4.widget.SwipeRefreshLayout></FrameLayout>
常用方法:
void setOnRefreshListener(SwipeRefreshLayout.OnRefreshListener listener) 设置刷新监听器
void setColorSchemeColors(int color1, int color2, int color3, int color4) 设置四种颜色进度条样式
void setRefreshing(boolean refreshing) 隐藏或显示进度条
boolean isRefreshing() 判断进度条是否显示
结合WebView使用也挺简单的,可以实现一些功能,下拉刷新当前网页、点击网页在当前页面中浏览并显示SwipeRefreshLayout进度条,整体来说还是不错的
public class Fragment5 extends Fragment {private View view;public WebView webview;private SwipeRefreshLayout swipeLayout;@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {view = inflater.inflate(R.layout.activity_fragment5, null);swipeLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_container);swipeLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {@Overridepublic void onRefresh() {//重新刷新页面webview.loadUrl(webview.getUrl());}});swipeLayout.setColorScheme(R.color.holo_blue_bright,R.color.holo_green_light, R.color.holo_orange_light,R.color.holo_red_light);webview = (WebView)view.findViewById(R.id.webview);webview.loadUrl("http://blog.csdn.net/h7870181");//添加javaScript支持webview.getSettings().setJavaScriptEnabled(true); //取消滚动条webview.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);//触摸焦点起作用webview.requestFocus();//点击链接继续在当前browser中响应 webview.setWebViewClient(new WebViewClient(){@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {view.loadUrl(url); return true; }});//设置进度条webview.setWebChromeClient(new WebChromeClient(){@Overridepublic void onProgressChanged(WebView view, int newProgress) {if (newProgress == 100) {//隐藏进度条swipeLayout.setRefreshing(false); } else { if (!swipeLayout.isRefreshing()) swipeLayout.setRefreshing(true); }super.onProgressChanged(view, newProgress);}});return view;}}
差点忘了贴出color.xml资源文件了,我呵了个呵!
<?xml version="1.0" encoding="utf-8"?><resources> <!-- A light Holo shade of blue --> <color name="holo_blue_light">#ff33b5e5</color> <!-- A light Holo shade of green --> <color name="holo_green_light">#ff99cc00</color> <!-- A light Holo shade of red --> <color name="holo_red_light">#ffff4444</color> <!-- A dark Holo shade of blue --> <color name="holo_blue_dark">#ff0099cc</color> <!-- A dark Holo shade of green --> <color name="holo_green_dark">#ff669900</color> <!-- A dark Holo shade of red --> <color name="holo_red_dark">#ffcc0000</color> <!-- A Holo shade of purple --> <color name="holo_purple">#ffaa66cc</color> <!-- A light Holo shade of orange --> <color name="holo_orange_light">#ffffbb33</color> <!-- A dark Holo shade of orange --> <color name="holo_orange_dark">#ffff8800</color> <!-- A really bright Holo shade of blue --> <color name="holo_blue_bright">#ff00ddff</color></resources>
没多大技术含量,纯属积累学习,还望大家见谅!
