我有一个博客的JSON内容,正在使用loadDataWithBaseURL
中的WebView
显示。该博客的许多文章都嵌入了youtube / vimeo视频。
当前,所有视频都在webview本身中播放。
我要实现的是,当用户单击播放视频时,他应该获得弹出窗口“使用浏览器或YouTube应用完成操作”。简而言之,我不希望视频在应用程序的webview中播放。
我发现了每个人都在尝试避免此弹出窗口的问题。.不知道为什么我没有得到它。
这是我的代码
public class DetailFragment extends Fragment {
String strTitle = null;
String strURL = null;
String strContent = null;
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
setHasOptionsMenu(true);
AdView mAdView = (AdView) getView().findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.detail_fragment, container, false);
strTitle = getArguments().getString("title");
strURL = getArguments().getString("url");
strContent = getArguments().getString("content");
String contToDisplay = "<html><head><meta http-equiv='Content-Type' content='text/html' charset='UTF-8' /></head><body><style type='text/css'> img{width:80%;} .wp-image-42223{display:none;}</style>" + strContent+"</body></html>";
TextView title = (TextView) view.findViewById(R.id.title);
WebView desc = (WebView) view.findViewById(R.id.desc);
WebSettings ws = desc.getSettings();
ws.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
ws.setJavaScriptEnabled(true);
ws.setLoadWithOverviewMode(true);
ws.setUseWideViewPort(true);
ws.setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);
ws.setUserAgentString("Mozilla/5.0 (Linux; U; Android 2.0; en-us; Droid Build/ESD20) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17");
title.setText(strTitle);
// desc.loadData(contToDisplay, "text/html; charset=UTF-8", null);
desc.loadDataWithBaseURL("about:blank",strContent,"text/html", "UTF-8", null);
return view;
}
}
任何将视频加载到浏览器或YouTube应用中的解决方案都将有所帮助。
注意
我在Web视图中显示的内容是HTML格式,其中iframe是元素之一。这是示例数据:
"<p>Some text</p>
<p><iframe src=\"https://www.youtube.com/embed/q7uBAtaK15I\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"></iframe> </p>
<p>some more text</p>
整个内容显示在webview中。我要实现的是,当某人单击iframe时,应提示他
complete action using
,即不允许该人在webview中播放视频 最佳答案
我设法使用正则表达式实现了这一点。
这是我所做的
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.detail_fragment, container, false);
strTitle = getArguments().getString("title");
strURL = getArguments().getString("url");
strContent = getArguments().getString("content");
contToDisplay = "<html><head><meta http-equiv='Content-Type' content='text/html' charset='UTF-8' /><script type='text/javascript'></script></head><body><style type='text/css'> img{width:80%;} .wp-image-42223{display:none;} </style>" + strContent+"</body></html>";
TextView title = (TextView) view.findViewById(R.id.title);
TextView date = (TextView) view.findViewById(R.id.date);
TextView authorName = (TextView) view.findViewById(R.id.auth);
desc = (WebView) view.findViewById(R.id.desc);
setHasOptionsMenu(true);
WebSettings ws = desc.getSettings();
ws.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
ws.setJavaScriptEnabled(true);
ws.setLoadWithOverviewMode(true);
ws.setUseWideViewPort(true);
ws.setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);
ws.setSupportMultipleWindows(true);
ws.setUserAgentString("Mozilla/5.0 (Linux; U; Android 2.0; en-us; Droid Build/ESD20) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17");
title.setText(strTitle);
final String s = strContent;
final String regex = "(?<=<iframe src=\")[^\"]*";
final String regex2 = "<\\s*iframe[^>]*><\\s*/\\s*iframe>";
p = Pattern.compile(regex);
final Pattern p2 = Pattern.compile(regex2);
m = p.matcher(s);
m2 = p2.matcher(s);
evaluate(s,contToDisplay,this);
desc.loadData(value, "text/html; charset=UTF-8", null);
return view;
}
String evaluate(String token,String defaultValue, DetailFragment context){
value=null;
Matcher matcher=p.matcher(token);
if (matcher.find()) {
iframeURL=matcher.group();
String newURL = "<a href=\"" + iframeURL + "\">Watch the Video Here</a>";
value = m2.replaceAll(newURL);
}
if (value == null) {
value=defaultValue;
}
return value != null ? value : "";
}
