我正在尝试让 JWPlayer 在播放本地视频的 Flash 播放器发生一些特定事件时返回警报。如果您从下面的代码中注意到,onComplete,JWPlayer 应该返回一个警报,然后可以由来自 setWebChromeClient 的 onJsAlert 拦截该警报,以便我可以使用该信息进行处理。我做错了吗?

一个可能的原因,我可以在这里找到:JWplayer Javascript interaction not working它正在本地加载。有什么办法可以绕过这个问题吗?通过调用 localhost 以某种方式加载会更容易吗?这可能吗?

对于那些好奇我为什么要生成 HTML 文件而不是仅仅从 Assets 中移动的那些人 - 在搜索 Internet 以弄清楚如何让本地 flv 播放器正常工作之后,最好的选择是生成 HTML包含自定义信息的文件并将文件写入与 FLV 相同的目录(因此是 FileWriter 函数)。

JWPlayer 嵌入的 HTML 代码:

private void createVideoHtml(File flvDirectory, File htmlFile, String videofilename)
{
String htmlPre = "<!DOCTYPE html><html lang=\"en\"><head><meta charset=\"utf-8\"></head><body style='margin:0; padding:0;'>";
String htmlCode =
"<script type='text/javascript' src='"+ flvDirectory.getAbsolutePath() + "/jwplayer.js'></script>" +
"<div id='mediaspace'>EZ Stream TV FLV Player</div>" +
"<script type='text/javascript'>" +
"jwplayer('mediaspace').setup({" +
"'flashplayer': '"+ flvDirectory.getAbsolutePath() + "/player.swf', 'file': '" + videofilename + "', 'backcolor': 'FFFFFF', 'frontcolor': '000000', 'lightcolor': '000000'," +
"'screencolor': '000000', 'volume': '100', 'autostart': 'true', 'mute': 'false', 'quality': 'false', 'controlbar': 'bottom', 'width': '100%', 'height': '100%'," +
"events: { " +
"onComplete: function() { alert('COMPLETED');}" +
"}});" +
"</script>";
String htmlPost = "</body></html>";
String finalHTML = htmlPre + htmlCode + htmlPost;

try {
FileWriter f = new FileWriter(htmlFile);
PrintWriter p = new PrintWriter(f);
p.print(finalHTML);
p.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

webview 和处理 JavaScript 警报的代码:

webView = (WebView)findViewById(R.id.web_player);
webView.getSettings().setBuiltInZoomControls(false);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadsImagesAutomatically(true);
webView.getSettings().setPluginsEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.getSettings().setAllowFileAccess(true);
webView.setInitialScale(60);
webView.setBackgroundColor(Color.BLACK);
getWindow().addFlags(128);
webView.getSettings().setUserAgentString("Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);

webView.setWebChromeClient(new WebChromeClient() {
@Override
public boolean onJsAlert(WebView view, String url, String message, final android.webkit.JsResult result)
{
Log.d(TAG, message);
new AlertDialog.Builder(view.getContext()).setMessage(message).setCancelable(true).show();
result.confirm();
return true;
}
});

最佳答案

JWPlayer转Webview可以引用下面的代码

private void createVideoHtml(File flvDirectory, File htmlFile, String videofilename)
{
String htmlPre = "<!DOCTYPE html><html lang="en"><head><meta charset="utf-8"></head><body style='margin:0; padding:0;'>";
String htmlCode =
"<script type='text/javascript' src='"+ flvDirectory.getAbsolutePath() + "/jwplayer.js'></script>" +
"<div id='mediaspace'>EZ Stream TV FLV Player</div>" +
"<script type='text/javascript'>" +
"jwplayer('mediaspace').setup({" +
"'flashplayer': '"+ flvDirectory.getAbsolutePath() + "/player.swf', 'file': '" + videofilename + "', 'backcolor': 'FFFFFF', 'frontcolor': '000000', 'lightcolor': '000000'," +
"'screencolor': '000000', 'volume': '100', 'autostart': 'true', 'mute': 'false', 'quality': 'false', 'controlbar': 'bottom', 'width': '100%', 'height': '100%'," +
"events: { " +
"onComplete: function() { alert('COMPLETED');}" +
"}});" +
"</script>";
String htmlPost = "</body></html>";
String finalHTML = htmlPre + htmlCode + htmlPost;

try {
FileWriter f = new FileWriter(htmlFile);
PrintWriter p = new PrintWriter(f);
p.print(finalHTML);
p.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

webView = (WebView)findViewById(R.id.web_player);
webView.getSettings().setBuiltInZoomControls(false);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadsImagesAutomatically(true);
webView.getSettings().setPluginsEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.getSettings().setAllowFileAccess(true);
webView.setInitialScale(60);
webView.setBackgroundColor(Color.BLACK);
getWindow().addFlags(128);
webView.getSettings().setUserAgentString("Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);

webView.setWebChromeClient(new WebChromeClient() {
@Override
public boolean onJsAlert(WebView view, String url, String message, final android.webkit.JsResult result)
{
Log.d(TAG, message);
new AlertDialog.Builder(view.getContext()).setMessage(message).setCancelable(true).show();
result.confirm();
return true;
}
});
