1.改清单文件

在你放置WebView的Activity的声明中加上以下代码：

android:hardwareAccelerated ="true"

android:configChanges="orientation|screenSize|keyboardHidden"

2.改Java类

1.对WebView进行初始化设置：

@JavascriptInterface

private void initWebView() {

WebSettings mWebSettings = mWebView.getSettings();

mWebSettings.setSupportZoom(true);

mWebSettings.setLoadWithOverviewMode(true);

mWebSettings.setUseWideViewPort(true);

mWebSettings.setDefaultTextEncodingName("utf-8");

mWebSettings.setLoadsImagesAutomatically(true);

mWebSettings.setBlockNetworkImage(false);//解决图片不显示

mWebSettings.setTextZoom(100);//设置默认缩放比例，防止网页跟随系统字体大小变化

//待定项目@{

mWebSettings.setAllowFileAccess(true);

mWebSettings.setJavaScriptCanOpenWindowsAutomatically(true);

mWebSettings.setDomStorageEnabled(true);// 必须保留，否则无法播放优酷视频，其他的OK

try {

if (Build.VERSION.SDK_INT >= 16) {

Class clazz = mWebSettings.getClass();

Method method = clazz.getMethod("setAllowUniversalAccessFromFileURLs", boolean.class);

if (method != null) {

method.invoke(mWebSettings, true);

}

} catch (Exception e) {

e.printStackTrace();

}

mWebSettings.setPluginState(WebSettings.PluginState.ON);

CookieManager cookieManager = CookieManager.getInstance();

cookieManager.setAcceptCookie(true);

//@}

//调用JS方法.安卓版本大于17,加上注解 @JavascriptInterface

mWebSettings.setJavaScriptEnabled(true);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

mWebSettings.setMixedContentMode(android.webkit.WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);

}

mWebView.setWebChromeClient(webChromeClient);

}

标明待定项目的属性设置可有可无，不影响本文说的功能实现。智汇代理申请

2.实现chrome代理：

WebChromeClient webChromeClient = new WebChromeClient() {

WebChromeClient.CustomViewCallback mCallback;

@Override

public void onShowCustomView(View view, CustomViewCallback callback) {

fullScreen();

mCallback = callback;

super.onShowCustomView(view, callback);

}

@Override

public void onHideCustomView() {

fullScreen();

super.onHideCustomView();

}

};

private void fullScreen() {

if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

LogUtil.i(TAG+" 横屏");

} else {

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

LogUtil.i(TAG+" 竖屏");

}

3.重写onConfigurationChanged方法：

@Override

public void onConfigurationChanged(Configuration newConfig) {

super.onConfigurationChanged(newConfig);

switch (newConfig.orientation) {

case Configuration.ORIENTATION_LANDSCAPE:

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

break;

case Configuration.ORIENTATION_PORTRAIT:

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

break;

}

OK，按照以上步骤粘贴完之后就大功告成了!你可以在直播平台里复制一个链接到该页面去打开，然后点击全屏观看直播测试一下。
