此答案只適用於Vimeo。經過大約十次失敗的嘗試後,這裏是我的工作。也許它會幫助別人。向其他SO答案的原作者致歉。我已經'借用了'下面的一些模式 - 只是認爲將所有這些放在一個地方很方便,並且不要爲我自己的代碼聲明它們。首先,我還沒有找到一種方法來嵌入Vimeo播放器(即無法直接訪問mp4流 - 至少不容易或不可靠 - 我敢肯定這是故意的)。其次,Vimeo提供了一個JavaScript庫來測試他們的播放器,並且使用它是相當不可避免的。請注意,它需要消息傳遞,這是一個較新的瀏覽器功能。這是記錄在他們的API頁面上。第三,正如其他地方所記載的那樣,你需要非常小心地等待堆疊的部分準備就緒,並且不要跳槍。第四,Vimeo播放器包含一個特別無用的背景圖像,意在表達該插件缺失或損壞(電影的一個小框架,這是常見的圖標)。真正意義的是,你的JavaScript已經在某個地方被轟炸了,沒有任何東西在運行。如果您在黑屏上看到電影的一點點,請檢查您的javascript。
第1步。設置WebView。你有上面這個正確的。作爲參考,這裏是我用過的。
mWebView = new WebView((Context) this);
mWebView.setLayoutParams(new LayoutParams(windowWidth, windowHeight));
mWebView.getSettings().setJavaScriptEnabled(true);
// Watch the sdk level here, < 12 requires 'false
// Wanted to force HTML5/264/mp4, you may want flash
// where still available
mWebView.getSettings().setPluginState(PluginState.OFF);
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.getSettings().setUserAgentString("Android Mozilla/5.0 AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30");
wcc = new MyWebChromeClient();
mWebView.setWebChromeClient(wcc);
wvc = new MyWebViewClient();
mWebView.setWebViewClient(wvc);
第2步。如果您希望視頻在WebView上工作,則需要WebChromeClient。這是記錄在這裏:http://developer.android.com/reference/android/webkit/WebView.html(見HTML視頻支持)。
再次,這裏的參考是我使用的。
private class MyWebChromeClient extends WebChromeClient {
@Override
public void onProgressChanged(WebView view, int progress) {
if(progress == 100) {
// Your page is loaded, but not visible,
// add whatever navigation elements you plan to use here.
// N.B. these are JAVA, not JS nav elements
}
}
@Override
public boolean onConsoleMessage(ConsoleMessage cm) {
// I like to watch in the console. And, since it was
// a very convenient way to monitor the javascript, I
// use it for that too. Purists will object, no doubt
if(cm.message().equalsIgnoreCase("EVENT -- Finish")) {
Log.i(TAG, "---> Finishing . . .");
// Depart the activity
finish();
} else {
Log.d(TAG, " **Console ["+cm.sourceId()+"] ("+cm.lineNumber()+") ["+cm.message()+"]");
}
return(true);
}
@Override
public View getVideoLoadingProgressView() {
// Something entertaining while the bytes arrive
Log.i(TAG, " -------------> Loading Progress . . . ");
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
return(inflater.inflate(R.layout.loading_video, null));
}
@Override
public void onShowCustomView(View v, WebChromeClient.CustomViewCallback callback) {
// With great sadness, I report that this never fires.
// Neither does the 'hide'.
}
@Override
public void onHideCustomView() {
}
}
的WebViewClient看起來是這樣的:
private class MyWebViewClient extends WebViewClient {
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
String injection = injectPageMonitor();
if(injection != null) {
Log.d(TAG, " ---------------> Page Loaded . . .");
Log.d(TAG, " Injecting . . . ["+injection+"]");
view.loadUrl(injection);
}
}
}
第3步:你需要建立的JavaScript點點火的球員。我用這個:
public String injectPageMonitor() {
return("javascript:" +
"jQuery(document).ready(function() { " +
"console.log(' === Page Ready ===> Setting up');" +
"console.log(' ==== Sending PLAY Command ===');" +
"var froogaloop = $f('froog');" +
"setTimeout(function() { froogaloop.api('play'); }, 3000);" +
"});");
}
快速說明。 。 。我在我的JS中使用jQuery,這是下面。這只是爲了方便,如果你想減輕負載,你可以做直JS。請注意,一切準備就緒後,腳本會等待另外3秒鐘才能實際觸發。在我虛弱的時刻,我想像Vimeo的友善人士有一個「準備好」的回調。 3秒似乎做到了。
第4步。您需要頁面上的一些HTML和JavaScript。我把它放在資源內的文本文件(raw/vimeo_frame.html)中。該文件是這樣的:
<!DOCTYPE html>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>
<script type="text/javascript">jQuery.noConflict();</script>
<script src="http://a.vimeocdn.com/js/froogaloop2.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function() {
var showing_player = false;
var froogaloop = $f('froog');
console.log(' === Page Ready ===> Setting up');
jQuery('.froog_container_class').hide();
jQuery('.console').css('height', '100%');
froogaloop.addEvent('ready', function() {
console.log('==== PLAYER READY ====> Setting Play Callback');
froogaloop.addEvent('play', function(data) {
console.log('EVENT -- Play');
/* No idea why, but if the player isn't displayed, it goes
straight to 'pause'. Probably a feature. So I give it 4x4px
to do it's thing during setup */
jQuery('.froog_container_class').show();
jQuery('.froog_container_class').css('height', '4px');
jQuery('.froog_container_class').css('width', '4px');
jQuery('.froog_container_class').css('overflow', 'hidden');
});
/* I don't want to reveal the video until it is actually
playing. So I do that here */
var showingPlayer = false;
froogaloop.addEvent('playProgress', function(data) {
if(!showingPlayer && data.percent > 0) {
showingPlayer = true;
jQuery('.froog_container_class').show();
jQuery('.froog_container_class').css('height', '_windowHeight');
jQuery('.froog_container_class').css('width', '_windowWidth');
/* Most tablets I tested aren't quick enough to make this work
but one can still hope */
jQuery('#loading').fadeOut('slow');
}
});
});
});
</script>
</head>
<body>
<style>
body {
background-image: url('http://<SomethingEntertainingToWatch>.png');
background-size: contain;
}
.mask {
float: left;
height: _windowHeight;
width: _windowWidth;
z-index: 100;
background: transparent;
display: inline;
position: absolute;
top: 0;
left: 0;
}
.froog_container_class {
position: absolute;
height: _windowHeight;
width: _windowWidth;
left: 0;
top: 0;
display: inline;
z-index: 1;
}
#froog {
display: inline;
height: _windowHeight;
width: _windowWidth;
postion: absolute;
top: 0;
left: 0;
}
</style>
<div id="loading" class="loading"><h1>Loading</h1><img class="loading_anim" src="http://foo.bar.com/assets/global/loading.gif"/>
</div>
<!-- Completely optional, I put a div in front of the player to block controls -->
<div id="mask" class="mask">
</div>
<div id="froog_container" class="froog_container_class">
<iframe id="froog" src="_targetUrl?api=1&title=0&byline=0&portrait=0&player_id=froog" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen>
</iframe>
</div>
</body>
</html>
我加載這個HTML文件,像這樣:
public String genMainHTML() {
String code = null;
try {
Resources res = getResources();
InputStream in_s = res.openRawResource(R.raw.vimeo_frame);
byte[] b = new byte[in_s.available()];
in_s.read(b);
code = new String(b);
} catch (Exception e) {
e.printStackTrace();
}
if(code != null) {
code = code.replaceAll("_windowHeight", "" + windowHeight + "px");
code = code.replaceAll("_windowWidth", "" + windowWidth + "px");
code = code.replaceAll("_targetUrl", targetUrl);
return(code);
} else {
return(null);
}
}
,並注入它像這樣:
mDomain = "http://player.vimeo.com";
mWebView.requestFocus(View.FOCUS_DOWN);
targetUrl = extras.getString("URL");
String meat = genMainHTML();
mWebView.loadDataWithBaseURL(mDomain, meat, "text/html", "utf-8", null);
setContentView(mWebView);
呼!當WebView準備就緒後,html和js進入,包括帶有Vimeo播放器的iframe。當文件被加載時,我們等待玩家準備就緒。當玩家準備好後,我們添加一些聽衆。 3秒鐘後,我們開始使用api'play'方法。
觀衆中的那些蘋果打火機可能會想知道,爲了完整起見,如何停止視頻?兩位。首先,當它結束時,我通過觀看控制檯輸出來顯示一條消息來停止它。因此:
public String injectPageFinisher() {
return("javascript:" +
"jQuery(document).ready(function() { " +
"console.log(' === Page Ready ===> Tearing down');" +
"console.log(' ==== Sending PAUSE Command ===');" +
"var froogaloop = $f('froog');" +
"froogaloop.api('pause');" +
"jQuery('#froog_container').html('');" +
"});");
}
可以插入像這樣:
@Override
public void onPause() {
super.onPause();
if(isFinishing()){
// Unload the page
if(mWebView != null) {
Log.i(TAG, " ------> Destroying WebView");
mWebView.destroy();
}
}
finish();
}
第二位是視頻完成其一點自我。因此,在上述vimeo_frame.html,只是「玩」回調後,我把:
froogaloop.addEvent('finish', function(data) {
console.log('EVENT -- Finish');
});
而在活動中,我說得有點看這個 - 見上面的onConsoleMessage覆蓋。
然而,截至撰寫本文時,我還沒有對一個嘮叨的問題進行排序。在WebView及其後代消失之後,MediaPlayer繼續存在。我確信這會產生一些問題,但我還沒有確定它們。
是上面的代碼是不是自動播放? – Venkat 2013-04-10 05:09:44
是的,我還設置了一個顯示/隱藏進度條的WebViewClient,不確定設置自定義的WebViewClient會影響它嗎? – scottyab 2013-04-11 09:35:09
但我嘗試了很多使用我們的代碼。但它不工作。所以我使用自定義的webview – Venkat 2013-04-22 07:17:24
