首先寫布局文件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="全屏不顯示該按扭,點擊切換橫屏" android:gravity="center" /> <WebView android:id="@+id/video_webview" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout>
原理:實現全屏的時候把webview里的視頻放到一個View(布局里的video_view控件)里面,然后把webview隱藏掉!這樣就實現了全屏播放的!
現在具體來看看怎么實現的:
先放代碼MainActivity.java:
public class MainActivity extends Activity { private FrameLayout videoview;// 全屏時視頻加載view private Button videolandport; private WebView videowebview; private Boolean islandport = true;//true表示此時是豎屏,false表示此時橫屏。 private View xCustomView; private xWebChromeClient xwebchromeclient; private String url = "http://look.appjx.cn/mobile_api.php?mod=news&id=12604"; private WebChromeClient.CustomViewCallback xCustomViewCallback; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE);//去掉應用標題 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.activity_main); initwidget(); initListener(); videowebview.loadUrl(url); } private void initListener() { // TODO Auto-generated method stub videolandport.setOnClickListener(new Listener()); } private void initwidget() { // TODO Auto-generated method stub videoview = (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 啟用或禁止WebView訪問文件數據 setBlockNetworkImage 是否顯示網絡圖像 * setBuiltInZoomControls 設置是否支持縮放 setCacheMode 設置緩沖的模式 * setDefaultFontSize 設置默認的字體大小 setDefaultTextEncodingName 設置在解碼時使用的默認編碼 * setFixedFontFamily 設置固定使用的字體 setJavaSciptEnabled 設置是否支持Javascript * setLayoutAlgorithm 設置布局方式 setLightTouchEnabled 設置用鼠標激活被選項 * setSupportZoom 設置是否支持變焦 * */ ws.setBuiltInZoomControls(true);// 隱藏縮放按鈕 ws.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);// 排版適應屏幕 ws.setUseWideViewPort(true);// 可任意比例縮放 ws.setLoadWithOverviewMode(true);// setUseWideViewPort方法設置webview推薦使用的窗口。setLoadWithOverviewMode方法是設置webview加載的頁面的模式。 ws.setSavePassword(true); ws.setSaveFormData(true);// 保存表單數據 ws.setJavaScriptEnabled(true); ws.setGeolocationEnabled(true);// 啟用地理定位 ws.setGeolocationDatabasePath("/data/data/org.itri.html5webview/databases/");// 設置定位的數據庫路徑 ws.setDomStorageEnabled(true); xwebchromeclient = new xWebChromeClient(); videowebview.setWebChromeClient(xwebchromeclient); videowebview.setWebViewClient(new xWebViewClientent()); } class Listener implements OnClickListener { @Override public void onClick(View v) { // TODO Auto-generated method stub switch (v.getId()) { case R.id.video_landport: if (islandport) { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); videolandport.setText("全屏不顯示該按扭,點擊切換橫屏"); }else { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); videolandport.setText("全屏不顯示該按扭,點擊切換豎屏"); } break; default: break; } } } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { if (inCustomView()) { hideCustomView(); return true; }else { videowebview.loadUrl("about:blank"); // mTestWebView.loadData("", "text/html; charset=UTF-8", null); MainActivity.this.finish(); Log.i("testwebview", "===>>>2"); } } return true; } /** * 判斷是否是全屏 * @return */ public boolean inCustomView() { return (xCustomView != null); } /** * 全屏時按返加鍵執行退出全屏方法 */ public void hideCustomView() { xwebchromeclient.onHideCustomView(); } /** * 處理Javascript的對話框、網站圖標、網站標題以及網頁加載進度等 * @author */ public class xWebChromeClient extends WebChromeClient { private Bitmap xdefaltvideo; private View xprogressvideo; @Override //播放網絡視頻時全屏會被調用的方法 public void onShowCustomView(View view, WebChromeClient.CustomViewCallback callback) { if (islandport) { } else{ // ii = "1"; // setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); } setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); videowebview.setVisibility(View.GONE); //如果一個視圖已經存在,那么立刻終止并新建一個 if (xCustomView != null) { callback.onCustomViewHidden(); return; } videoview.addView(view); xCustomView = view; xCustomViewCallback = callback; videoview.setVisibility(View.VISIBLE); } @Override //視頻播放退出全屏會被調用的 public void onHideCustomView() { if (xCustomView == null)//不是全屏播放狀態 return; // Hide the custom view. setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); xCustomView.setVisibility(View.GONE); // Remove the custom view from its container. videoview.removeView(xCustomView); xCustomView = null; videoview.setVisibility(View.GONE); xCustomViewCallback.onCustomViewHidden(); videowebview.setVisibility(View.VISIBLE); //Log.i(LOGTAG, "set it to webVew"); } //視頻加載添加默認圖標 @Override public Bitmap getDefaultVideoPoster() { //Log.i(LOGTAG, "here in on getDefaultVideoPoster"); if (xdefaltvideo == null) { xdefaltvideo = BitmapFactory.decodeResource( getResources(), R.drawable.videoicon); } return xdefaltvideo; } //視頻加載時進程loading @Override public View getVideoLoadingProgressView() { //Log.i(LOGTAG, "here in on getVideoLoadingPregressView"); if (xprogressvideo == null) { LayoutInflater inflater = LayoutInflater.from(MainActivity.this); xprogressvideo = inflater.inflate(R.layout.video_loading_progress, null); } return xprogressvideo; } //網頁標題 @Override public void onReceivedTitle(WebView view, String title) { (MainActivity.this).setTitle(title); } // @Override // //當WebView進度改變時更新窗口進度 // public void onProgressChanged(WebView view, int newProgress) { // (MainActivity.this).getWindow().setFeatureInt(Window.FEATURE_PROGRESS, newProgress*100); // } } /** * 處理各種通知、請求等事件 * @author */ public class xWebViewClientent extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { Log.i("webviewtest", "shouldOverrideUrlLoading: "+url); return false; } } /** * 當橫豎屏切換時會調用該方法 * @author */ @Override public void onConfigurationChanged(Configuration newConfig) { Log.i("testwebview", "=====<<< onConfigurationChanged >>>====="); super.onConfigurationChanged(newConfig); if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE){ Log.i("webview", " 現在是橫屏1"); islandport = false; }else if(newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){ Log.i("webview", " 現在是豎屏1"); islandport = true; } } }
最后說下AndroidManifest.xml設置;
訪問網絡權限加上這句
<uses-permission android:name="android.permission.INTERNET"/>
當切換橫豎屏時為了不重新調用onCreate等方法,要加個這句:
android:configChanges="orientation|keyboardHidden|screenSize"
總結
