我想使用iframe将youtube视频加载到Android webview
这是我的布局Xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@android:color/white"
android:id="@+id/mainLayout">
<WebView
android:background="@android:color/white"
android:id="@+id/webView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
我的代码是:
public class WebTube extends Activity {
private WebView wv;
String html = "<iframe class=\"youtube-player\" style=\"border: 0; width: 100%; height: 95%; padding:0px; margin:0px\" id=\"ytplayer\" type=\"text/html\" src=\"http://www.youtube.com/embed/WBYnk3zR0os"
+ "?fs=0\" frameborder=\"0\">\n"
+ "</iframe>";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
wv = (WebView)findViewById(R.id.webView);
wv.getSettings().setJavaScriptEnabled(true);
wv.loadDataWithBaseURL("", html , "text/html", "UTF-8", "");
}
}
我也提供<uses-permission android:name="android.permission.INTERNET"/>
&安培; android:hardwareAccelerated="true"
当我运行时,我没有得到任何结果它只是显示黑屏
我尝试了this。但这会在.3gp Quality
上为我提供视频。但是我需要来自youtube的原始质量的视频。这就是我使用iframe
的原因。
我使用<object></object>
和<video></video>
代替iframe
来尝试代码。但它没有解决我的问题。
当我在模拟器上运行此代码时,它显示
按下播放按钮之前
按视频上的播放按钮后
我认为我们无法在模拟器上传输视频,因为它是虚拟设备
但是当我在手机上运行它时,它甚至没有显示出这个结果。
我尝试使用附加文档的iframe在手机和模拟器上工作正常
String customHtml = "<iframe src='http://docs.google.com/viewer?url=http://www.iasted.org/conferences/formatting/presentations-tips.ppt&embedded=true' width='100%' height='100%' style='border: none;'></iframe>";
所以请帮我把视频加载到这个框架。
(我在手机上运行)。有什么问题? iframe也适用于Android 2.1吗?
是否有人试过Youtube Api?

如android Webview documentation中所述,
HTML5视频支持
要在您的应用中支持内联HTML5视频,您需要启用硬件加速,并设置WebChromeClient 。
对于全屏支持,需要实现onShowCustomView(View,WebChromeClient.CustomViewCallback)和onHideCustomView(),getVideoLoadingProgressView()是可选的。

我为youtube视图提供了完整的自定义ifram
public class Act_VideoPlayer extends Activity {
WebView webView;
ProgressBar progressBar;
ImageView back_btn;
String video_url = "KK9bwTlAvgo", html = "";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.full_screen_youtube_video_screen);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
back_btn = (ImageView) findViewById(R.id.full_videoview_btn);
back_btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
webView.loadData("", "text/html", "UTF-8");
finish();
}
});
webView = (WebView) findViewById(R.id.webView);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
if (video_url.equalsIgnoreCase("")) {
finish();
return;
}
WebSettings ws = webView.getSettings();
ws.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);
ws.setPluginState(WebSettings.PluginState.ON);
ws.setJavaScriptEnabled(true);
webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
webView.reload();
if (networkUtil.isConnectingToInternet(Act_VideoPlayer.this)) {
html = getHTML(video_url);
} else {
html = "" + getResources().getString(R.string.The_internet_connection_appears_to_be_offline);
CustomToast.animRedTextMethod(Act_VideoPlayer.this, getResources().getString(R.string.The_internet_connection_appears_to_be_offline));
}
webView.loadData(html, "text/html", "UTF-8");
WebClientClass webViewClient = new WebClientClass(progressBar);
webView.setWebViewClient(webViewClient);
WebChromeClient webChromeClient = new WebChromeClient();
webView.setWebChromeClient(webChromeClient);
}
@Override

}
}
@Override
public void onBackPressed() {
super.onBackPressed();
try {
webView.loadData("", "text/html", "UTF-8");
finish();
} catch (Exception e) {
e.printStackTrace();
}
}
public class WebClientClass extends WebViewClient {
ProgressBar ProgressBar = null;
WebClientClass(ProgressBar progressBar) {
ProgressBar = progressBar;
}
@Override

ProgressBar.setVisibility(View.VISIBLE);
}
@Override

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
LogShowHide.LogShowHideMethod("webview-click :", "" + url.toString());
view.loadUrl(getHTML(video_url));
return true;
}
}
public String getHTML(String videoId) {
String html = "<iframe class=\"youtube-player\" " + "style=\"border: 0; width: 100%; height: 96%;"

LogShowHide.LogShowHideMethod("video-id from html url= ", "" + html);
return html;
}
}

这对我有用:
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
String frameVideo = "<html><body>Youtube video .. <br> <iframe width=\"320\" height=\"315\" src=\"https://www.youtube.com/\" frameborder=\"0\" allowfullscreen></iframe></body></html>";
mWebView.loadData(frameVideo, "text/html", "utf-8");
mWebView.loadUrl("http://www.youtube.com/");
mWebView.setWebViewClient(new WebViewClient());

试试这个工作正常..

}
};
mWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
mWebView.setWebChromeClient(mWebChromeClient);

答案 4 :(得分:0)
我不是Android webview的专家,但我在网页上遇到了类似的问题。
我要做的就是使用标签并确保它在标签中有onclick =“this.play();. onclick事件专门用于Android.Chrome,Safari,Firefox不需要它。< / p>
例如:
<video id="video" width="320" height="240" autobuffer controls onclick="this.play();">
如果没有onclick,Android浏览器就无法运行。由于webview正在调用浏览器,我怀疑它是一样的。
并确保在源标记中不使用编解码器属性。
希望这会对你有所帮助。

这不是您问题的直接答案,但我相信您可能希望使用新发布的Android Youtube API。它应该允许将youtube视频播放添加到您的应用中,因此您不必将它们注入iFrame中的webview中。这很愚蠢,并非所有Android设备都安装了Flash:)

您可以再次访问我的question。我创建了一个功能,为您提供所有YouTube视频的直接链接(包括hq链接)。现在你可以使用mp4而不是可怜的3gp。

使用WebChromeClient可以处理Javascript对话框,favicon,标题和进度:

工作正常
我的Java文件
String path="<iframe src='https://www.youtube.com/embed/eWEF1Zrmdow' width='100%' height='100%' style='border: none;'></iframe>";
webView.loadData(path,"text/html","utf-8");
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient());
