我知道这是一个古老的问题,并且多次被问过。但我尝试了很多解决方案,他们不能和我合作。
我在华为6P和三星S7,Nexus 5中进行了测试, WebView中的视频(https://www.youtube-nocookie.com/embed/M68lNfqmTNk?rel=0&rel=0&showinfo=0)无法按预期工作(去年有效)。 当我单击全屏按钮时,会连续调用“onShowCustomView”和“onHideCustomView”。所以我可以看到视频闪烁(非全屏 - >全屏 - >非全屏)。 有时如果我很幸运,视频会进入全屏模式,但如果按全屏按钮退出全屏模式,该按钮根本不起作用。
我在GitHub写了一个演示,希望有人可以帮助我。感谢。
这是代码
Init Webview:
mWebView = (WebView)findViewById(R.id.webview);
mWebChromeClient = new MyWebChromeClient();
mWebView.setWebChromeClient(mWebChromeClient);
mWebView.setWebViewClient(new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
mWebView.loadUrl(url);
return true;
}
});
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setUseWideViewPort(true);
webSettings.setAllowFileAccess(true);
webSettings.setSupportZoom(true);
webSettings.setLoadWithOverviewMode(true);
webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);
MyWebChromeClient:
public class MyWebChromeClient extends WebChromeClient {
FrameLayout.LayoutParams LayoutParameters = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT);
@Override
public void onShowCustomView(View view, CustomViewCallback callback) {
Log.d("youtube", "onShowCustomView");
// if a view already exists then immediately terminate the new one
if (mCustomView != null) {
callback.onCustomViewHidden();
return;
}
mContentView = (ConstraintLayout) findViewById(R.id.activity_main);
mContentView.setVisibility(View.GONE);
mCustomViewContainer = new FrameLayout(MainActivity.this);
mCustomViewContainer.setLayoutParams(LayoutParameters);
mCustomViewContainer.setBackgroundResource(android.R.color.black);
view.setLayoutParams(LayoutParameters);
mCustomViewContainer.addView(view);
mCustomView = view;
mCustomViewCallback = callback;
mCustomViewContainer.setVisibility(View.VISIBLE);
setContentView(mCustomViewContainer);
}
@Override
public void onHideCustomView() {
Log.d("youtube", "onHideCustomView");
if (mCustomView == null) {
return;
} else {
// Hide the custom view.
mCustomView.setVisibility(View.GONE);
// Remove the custom view from its container.
mCustomViewContainer.removeView(mCustomView);
mCustomView = null;
mCustomViewContainer.setVisibility(View.GONE);
mCustomViewCallback.onCustomViewHidden();
// Show the content view.
mContentView.setVisibility(View.VISIBLE);
setContentView(mContentView);
}
}
}
我在AndroidManifest.xml中设置了android:hardwareAccelerated
android:hardwareAccelerated="true"

要在网页浏览中加载YouTube视频,您必须改用iframe, 例如:
<iframe width="300" height=".." src="http://www.youtube.com/embed/M68lNfqmTNk" frameborder="0" allowfullscreen></iframe>
并将html文本加载到webview,如下所示:<html><body> <iframe width="330" height="315" src="http://www.youtube.com/embed/M68lNfqmTNk" frameborder="0" allowfullscreen></iframe>....
