我想在我的Android應用程序流再現視頻和我有我的應用程序內的下一個HTML文件複製視頻:調用JavaScript的通過流中的Android
<!doctype html>
<html>
<head>
<script type="text/javascript">
var vid;
function init() {
vid = document.getElementById("myVideo");
}
function loadVideoSource(videoSource) {
vid.setAttribute("src", videoSource);
vid.load();
vid.play();
}
function stopVideoSource(){
vid.pause();
}
function resizeBig(screenWidth, screenHeight){
vid.style.width =screenWidth;
vid.style.height =screenHeight;
}
function resizeSmall(){
vid.style.width ='320px';
vid.style.height ='180px';
}
</script>
</head>
<body onload="init()">
<video src="" id="myVideo" optimized_for_streaming="true" autoplay="autoplay" x-webkit-airplay="allow" controls="controls" webkit-playsinline preload="metadata" height="180" width="320">
</video>
</body>
</html>
這是活動從中我想打電話給HTML文件內的JavaScript函數:
public class WebviewVideoRep extends Activity{
private WebView mWebView;
private LinearLayout mContentView;
private FrameLayout mCustomViewContainer;
private WebChromeClient.CustomViewCallback mCustomViewCallback;
FrameLayout.LayoutParams COVER_SCREEN_GRAVITY_CENTER = new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT, Gravity.CENTER);
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview_activity);
mContentView = (LinearLayout) findViewById(R.id.linearlayout);
mWebView = (WebView) findViewById(R.id.webView);
mCustomViewContainer = (FrameLayout) findViewById(R.id.fullscreen_custom_content);
WebSettings webSettings = mWebView.getSettings();
webSettings.setPluginState(WebSettings.PluginState.ON);
webSettings.setJavaScriptEnabled(true);
webSettings.setUseWideViewPort(true);
webSettings.setLoadWithOverviewMode(true);
mWebView.loadUrl("file:///android_asset/video_player.html");
mWebView.setWebViewClient(new HelloWebViewClient());
mWebView.loadUrl("javascript:loadVideoSource('videoUrl')");
}
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView webview, String url)
{
webview.setWebChromeClient(new WebChromeClient() {
private View mCustomView;
@Override
public void onShowCustomView(View view, WebChromeClient.CustomViewCallback callback)
{
// if a view already exists then immediately terminate the new one
if (mCustomView != null)
{
callback.onCustomViewHidden();
return;
}
// Add the custom view to its container.
mCustomViewContainer.addView(view, COVER_SCREEN_GRAVITY_CENTER);
mCustomView = view;
mCustomViewCallback = callback;
// hide main browser view
mContentView.setVisibility(View.GONE);
// Finally show the custom view container.
mCustomViewContainer.setVisibility(View.VISIBLE);
mCustomViewContainer.bringToFront();
}
});
webview.loadUrl(url);
return true;
}
}
public class JavaScriptInterface {
Context mContext;
/** Instantiate the interface and set the context */
JavaScriptInterface(Context c) {
mContext = c;
}
}
}
這是佈局:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<FrameLayout
android:id="@+id/fullscreen_custom_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FF000000"/>
<LinearLayout
android:id="@+id/linearlayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<WebView
android:id="@+id/webView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
</RelativeLayout>
當我開始這個活動時,在屏幕上出現白色的視頻屏幕,播放/暫停等等控制器,但視頻不會被重現。還有什麼我需要重現視頻?我做錯了什麼?
嘗試過,但仍然無法正常工作。我已經嘗試了幾個網址,但仍然有一個繁殖者 –
剛編輯帖子。希望能幫助到你。 –
我嘗試不使用'onShowCustomView'方法,但也不起作用。我也嘗試過您使用的視頻。讀一些其他的帖子,我知道有時他們會使用媒體播放器,但我沒有使用任何媒體播放器,是否有必要?請注意,這是我用來播放視頻的所有代碼 –
