Android programming for WebView full-screen playback

This article mainly describes the Android programming to achieve webview full-screen playback method, combined with the case of the form of more detailed analysis of the Android WebView full-screen playback of the layout and function-related skills, the need for friends can refer to the next!

The examples in this paper describe how Android programming implements WebView full-screen playback. Share to everyone for your reference, as follows:

Recently because the project to use WebView load HTML5 video, start not full-screen broadcast, did a long time to make! So, according to my understanding, how to achieve full screen it.

First write the layout file Activity_main.xml:

<linearlayout xmlns:android= "Http://schemas.android.com/apk/res/android"Xmlns:tools= "Http://schemas.android.com/tools"Android:id= "@+id/container"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"android:orientation= "Vertical" > <framelayout Android:id= "@+id/video_view"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"android:visibility= "Gone" ></FrameLayout> <Button Android:id= "@+id/video_landport"Android:layout_width= "Fill_parent"Android:layout_height= "Wrap_content"Android:text= "Full screen does not display the button, click to toggle Horizontal Screen"android:gravity= "Center"/> <WebView Android:id= "@+id/video_webview"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"/> </LinearLayout>

View Code

Principle: To achieve full-screen when the WebView video into a view (the layout of the Video_view control) inside, and then the WebView hidden away! This enables full-screen playback!
Now take a look at how it's implemented:

First put code Mainactivity.java:

 Public classMainactivityextendsActivity {PrivateFramelayout Videoview;//Video Load View when full screen PrivateButton Videolandport;PrivateWebView Videowebview;PrivateBoolean Islandport =true;//True indicates that this is a vertical screen and false indicates a horizontal screen at this time.  PrivateView Xcustomview;Privatexwebchromeclient xwebchromeclient;PrivateString url = "http://look.appjx.cn/mobile_api.php?mod=news&id=12604"; Privatewebchromeclient.customviewcallback xcustomviewcallback; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate); Requestwindowfeature (window.feature_no_title);//Remove app titleGetWindow (). SetFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN  );  Setcontentview (R.layout.activity_main);  Initwidget ();  Initlistener (); Videowebview.loadurl (URL); } Private voidInitlistener () {//TODO auto-generated Method StubVideolandport.setonclicklistener (NewListener ()); } Private voidInitwidget () {//TODO auto-generated Method StubVideoview =(framelayout) Findviewbyid (R.id.video_view); Videolandport=(Button) Findviewbyid (R.id.video_landport); Videowebview=(WebView) Findviewbyid (R.id.video_webview); WebSettings ws=videowebview.getsettings (); /*** Setallowfileaccess Enables or disables WebView access to file data setblocknetworkimage whether the network image is displayed * Setbuiltinzoomcontrols settings support scaling Setcachem Ode Set Buffered Mode * setdefaultfontsize set default font size setdefaulttextencodingname Set default encoding used when decoding * setfixedfontfamily set fixed used font set Javasciptenabled Settings Support JavaScript * Setlayoutalgorithm set layout mode setlighttouchenabled settings with mouse activation by option * Setsupportzoom settings support variable Coke **/Ws.setbuiltinzoomcontrols (true);//Hide Zoom buttonWs.setlayoutalgorithm (WebSettings.LayoutAlgorithm.NARROW_COLUMNS);//Typesetting adaptation ScreenWs.setusewideviewport (true);//can be scaled at any scaleWs.setloadwithoverviewmode (true);//the Setusewideviewport method sets the window recommended for use by WebView.

View Code

I wrote a lot of comments in the code, I believe that we can understand, of course, I am a rookie, there may be some places to understand the wrong! You know, you can tell me. Then I added a function in it, is to click on the WebView above button to switch the screen! There is also when clicking on full screen playback force horizontal screen playback, click Back to the vertical screen! I do not use mobile phone gravity sensor to switch the screen! The code also added a playback progress of the layout file, we can see in the source!

Finally say Androidmanifest.xml set;

Access network permissions plus this sentence:

<uses-permission android:name= "Android.permission.INTERNET"/>

When switching the screen in order to not recall OnCreate and other methods, to add this sentence:

Android:configchanges= "Orientation|keyboardhidden|screensize"

Almost so that you can achieve full-screen playback, if you do not understand the question can ask me,
