我正在一个基于网站的
Android应用程序.
iOS应用程序已经存在,我必须尊重一些代码的一致性.
iOS应用程序已经存在,我必须尊重一些代码的一致性.
一切都已经完成了,但是我刚刚发现了一个有趣的问题：当使用网页视图(我没有显示页面的任何控件)时,对于具有iframe视频(Youtube,Dailymotion)的页面,它不会全屏即使我按下播放器的按钮.
我已经尝试了很多这里发现的一切,但它只是指应用程序,我知道你需要显示哪些页面.
以下是该应用的webActivity部分的代码：
public class WebActivity extends Activity {
String targetURL = "";
String title = "";
WebView wv;
@Override
public void onResume() { super.onResume(); CookieSyncManager.getInstance().startSync(); }
@Override
public void onPause() { super.onPause(); CookieSyncManager.getInstance().stopSync(); }
/** Called when the activity is first created. */
@SuppressLint("SetJavaScriptEnabled")
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_PROGRESS);
//getWindow().requestFeature(Window.FEATURE_NO_TITLE);
CookieSyncManager.createInstance(getApplicationContext());
CookieSyncManager.getInstance().startSync();
CookieManager.getInstance().setAcceptCookie(true);
/**
* TODO: WebView Cookie management.
* Right now,a cookie is hardcoded here into the WebView instead of getting it from the API called by HttpClient when retrieving the JSON.
* Need to make things cleaner.
*/
CookieManager.getInstance().setCookie("http://www.blabla.fr/mobile/","gbapi=1; Domain=.www.blabla.fr");
/**
* Get parameters
*/
Bundle b = getIntent().getExtras();
if(b != null)
{
targetURL = b.getString("url");
title = b.getString("title");
}
setTitle(title);
setContentView(R.layout.activity_webview);
wv = (WebView) findViewById(R.id.webview);
WebSettings wvSettings = wv.getSettings();
// WebView options
wvSettings.setDefaultTextEncodingName("utf-8");
wvSettings.setJavaScriptEnabled(true);
wvSettings.setPluginState(PluginState.ON);
wvSettings.setJavaScriptCanOpenWindowsAutomatically(true);
wvSettings.setBuiltInZoomControls(true);
final Activity activity = this;
wv.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view,int progress) {
activity.setProgress(progress * 100);
}
});
wv.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view,int errorCode,String description,String failingUrl) {
Toast.makeText(activity,"Oh snap! " + description,Toast.LENGTH_SHORT).show();
}
});
wv.loadUrl(targetURL);
}
}
感谢任何帮助.
解决方法
您将需要创建一个自定义WebChromeClient来处理两个版本的onShowCustomView(这个回调的新版本在API级别14中引入)以及onHideCustomView.基本上会发生什么,当您尝试播放全屏视频时,您将获得视频视频的一些变化.您需要将其附加到全屏FrameLayout,并将其粘贴到布局层次结构的根目录以覆盖整个屏幕.一旦完成,你需要再次删除它.
这是一个我用来播放视频的版本
private class DerpChromeClient extends WebChromeClient implements MediaPlayer.OnCompletionListener,MediaPlayer.OnErrorListener {
//@Override
public void onShowCustomView(View view,int requestedOrientation,CustomViewCallback callback) {
log.warn("onShowCustomView");
showCustomView(view,callback);
}
private View mVideoProgressView;
@Override
public void onHideCustomView() {
super.onHideCustomView();
activity.removeFullscreenView();
webView.setVisibility(View.VISIBLE);
try {
mCustomViewCallback.onCustomViewHidden();
} catch (NullPointerException npe) {
// occasionally Android likes to freak out and throw an unhandled NPE if it can't play the video
// therefore we are not going to do anything but eat this exception so it fails gracefully
}
mCustomView = null;
mVideoView = null;
}
@Override
public void onShowCustomView(View view,CustomViewCallback callback) {
super.onShowCustomView(view,callback);
log.warn("onShowCustomView");
showCustomView(view,callback);
}
private void showCustomView(View view,CustomViewCallback callback) {
if (mCustomView != null) {
callback.onCustomViewHidden();
return;
}
mCustomView = view;
mCustomViewCallback = callback;
webView.setVisibility(View.GONE);
if (view instanceof FrameLayout) {
if (((FrameLayout)view).getFocusedChild() instanceof VideoView) {
mVideoView = (VideoView)((FrameLayout)view).getFocusedChild();
}
}
view.setLayoutParams(new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,FrameLayout.LayoutParams.MATCH_PARENT));
view.setBackgroundColor(Color.BLACK);
activity.displayFullscreenView(view);
}
@Override
public boolean onConsoleMessage(ConsoleMessage cm) {
log.warn("Console Message: " + cm.message() + " on line " + cm.lineNumber() + " of " + cm.sourceId());
return super.onConsoleMessage(cm);
}
@Override
public void onProgressChanged(WebView view,int newProgress) {
super.onProgressChanged(view,newProgress);
if (newProgress < 100) {
if (loadingProgress.getVisibility() == ProgressBar.GONE) {
loadingProgress.setVisibility(ProgressBar.VISIBLE);
}
loadingProgress.setProgress(newProgress);
} else if (newProgress >= 100) {
loadingProgress.setVisibility(ProgressBar.GONE);
}
}
@Override
public View getVideoLoadingProgressView() {
if (mVideoProgressView == null) {
LayoutInflater inflater = LayoutInflater.from(KnowledgeBaseFragment.this.getActivity().getApplicationContext());
mVideoProgressView = inflater.inflate(R.layout.video_loading_progress,null);
}
return mVideoProgressView;
}
@Override
public boolean onError(MediaPlayer mp,int what,int extra) {
// TODO Auto-generated method stub
return false;
}
@Override
public void onCompletion(MediaPlayer mp) {
this.onHideCustomView();
}
}
请注意,我在片段中进行此操作,因此为了使其真正全屏,我必须将其与活动紧密耦合,以便将FrameLayout附加到整个视图层次结构的根目录,而不仅仅是片段.
以下是这些功能：
@Override
public void displayFullscreenView(View customView) {
parentLayout.addView(customView);
this.customView = customView;
}
@Override
public void removeFullscreenView() {
if (customView != null) {
customView.setVisibility(View.GONE);
parentLayout.removeView(customView);
}
customView = null;
}
这是另一个像你的问题：WebView and HTML5 <video>
