本文主要是将最近工作中遇到的一个问题进行总结分享，主要介绍的是如何让WebView中H5页面全屏播放视频。关于这个问题，做一下简单分析，希望对大家有所帮助，下面话不多说了，来看看详细的介绍吧。

效果图

运行效果

其实很简单，就是配置问题。关键地方配好了，基本没什么问题了。

硬件加速
设置WebView

在清单需要配置的AndroidManifest.xml

<application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".WebViewActivity" android:configChanges="orientation|screenSize|keyboardHidden" android:hardwareAccelerated="true"> <intent-filter>  <action android:name="android.intent.action.MAIN" />  <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity></application>

这里需要注意的是：启动硬件加速可以在application 启动这个硬件加速，也可以在对应的activity启动

android:hardwareAccelerated="true"

还有这个

configChanges="orientation|screenSize|keyboardHidden"

必须是

orientation|screenSize|keyboardHidden

当然记得加上网络权限

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

下面给出全部源码

activity_webview.xml

<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mFrameLayout" android:layout_width="match_parent" android:layout_height="match_parent"> <WebView android:id="@+id/mWebView" android:layout_width="match_parent" android:layout_height="match_parent" /></FrameLayout>

WebViewActivity源码

public class WebViewActivity extends AppCompatActivity { private FrameLayout mFrameLayout; private WebView mWebView; private MyWebChromeClient mMyWebChromeClient; private String URL = "http://m.tv.sohu.com/20130704/n380744170.shtml"; @Override protected void onCreate(Bundle savedInstanceState) { requestWindowFeature(Window.FEATURE_NO_TITLE); super.onCreate(savedInstanceState); setContentView(R.layout.activity_webview); mFrameLayout = (FrameLayout) findViewById(R.id.mFrameLayout); mWebView = (WebView) findViewById(R.id.mWebView); initWebView(); mWebView.loadUrl(URL); } private void initWebView() { WebSettings settings = mWebView.getSettings(); settings.setJavaScriptEnabled(true); settings.setJavaScriptCanOpenWindowsAutomatically(true); settings.setPluginState(WebSettings.PluginState.ON); settings.setAllowFileAccess(true); settings.setLoadWithOverviewMode(true); settings.setUseWideViewPort(true); settings.setCacheMode(WebSettings.LOAD_NO_CACHE); settings.setCacheMode(WebSettings.LOAD_DEFAULT); mMyWebChromeClient = new MyWebChromeClient(); mWebView.setWebChromeClient(mMyWebChromeClient); mWebView.setWebViewClient(new WebViewClient() {  public boolean shouldOverrideUrlLoading(WebView view, String url) {  view.loadUrl(url);  return true;  }  @Override  public void onPageFinished(WebView view, String url) {  super.onPageFinished(view, url);  } }); } private class MyWebChromeClient extends WebChromeClient { private View mCustomView; private CustomViewCallback mCustomViewCallback; @Override public void onShowCustomView(View view, CustomViewCallback callback) {  super.onShowCustomView(view, callback);  if (mCustomView != null) {  callback.onCustomViewHidden();  return;  }  mCustomView = view;  mFrameLayout.addView(mCustomView);  mCustomViewCallback = callback;  mWebView.setVisibility(View.GONE);  setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); } public void onHideCustomView() {  mWebView.setVisibility(View.VISIBLE);  if (mCustomView == null) {  return;  }  mCustomView.setVisibility(View.GONE);  mFrameLayout.removeView(mCustomView);  mCustomViewCallback.onCustomViewHidden();  mCustomView = null;  setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);  super.onHideCustomView(); } } @Override public void onConfigurationChanged(Configuration config) { super.onConfigurationChanged(config); switch (config.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; } } @Override public void onPause() { super.onPause(); mWebView.onPause(); } @Override public void onResume() { super.onResume(); mWebView.onResume(); } @Override public void onBackPressed() { if (mWebView.canGoBack()) {  mWebView.goBack();  return; } super.onBackPressed(); } @Override public void onDestroy() { super.onDestroy(); mWebView.destroy(); }}
