The Android Open Source Project | 9066cfe | 2009-03-03 19:31:44 -0800 | [diff] [blame] | 87 | * can roll your own web browser or simply display some online content within your Activity. |
| 88 | * It uses the WebKit rendering engine to display |
| 89 | * web pages and includes methods to navigate forward and backward |
| 90 | * through a history, zoom in and out, perform text searches and more.</p> |

| 101 | * <h3>Basic usage</h3> |
| 102 | * |
| 103 | * <p>By default, a WebView provides no browser-like widgets, does not |
| 104 | * enable JavaScript and errors will be ignored. If your goal is only |
| 105 | * to display some HTML as a part of your UI, this is probably fine; |
| 106 | * the user won't need to interact with the web page beyond reading |
| 107 | * it, and the web page won't need to interact with the user. If you |
| 108 | * actually want a fully blown web browser, then you probably want to |
| 109 | * invoke the Browser application with your URL rather than show it |
| 110 | * with a WebView. See {@link android.content.Intent} for more information.</p> |
| 111 | * |
| 112 | * <pre class="prettyprint"> |
| 113 | * WebView webview = new WebView(this); |
| 114 | * setContentView(webview); |
| 115 | * |
| 116 | * // Simplest usage: note that an exception will NOT be thrown |
| 117 | * // if there is an error loading this page (see below). |
| 118 | * webview.loadUrl("http://slashdot.org/"); |
| 119 | * |
| 120 | * // Of course you can also load from any string: |
| 121 | * String summary = "<html><body>You scored <b>192</b> points.</body></html>"; |
| 122 | * webview.loadData(summary, "text/html", "utf-8"); |
| 123 | * // ... although note that there are restrictions on what this HTML can do. |
| 124 | * // See the JavaDocs for loadData and loadDataWithBaseUrl for more info. |
| 125 | * </pre> |
| 126 | * |
| 127 | * <p>A WebView has several customization points where you can add your |
| 128 | * own behavior. These are:</p> |
| 129 | * |
| 130 | * <ul> |
| 131 | * <li>Creating and setting a {@link android.webkit.WebChromeClient} subclass. |
| 132 | * This class is called when something that might impact a |
| 133 | * browser UI happens, for instance, progress updates and |
| 134 | * JavaScript alerts are sent here. |
| 135 | * </li> |
| 136 | * <li>Creating and setting a {@link android.webkit.WebViewClient} subclass. |
| 137 | * It will be called when things happen that impact the |
| 138 | * rendering of the content, eg, errors or form submissions. You |
| 139 | * can also intercept URL loading here.</li> |
| 140 | * <li>Via the {@link android.webkit.WebSettings} class, which contains |
| 141 | * miscellaneous configuration. </li> |
| 142 | * <li>With the {@link android.webkit.WebView#addJavascriptInterface} method. |
| 143 | * This lets you bind Java objects into the WebView so they can be |
| 144 | * controlled from the web pages JavaScript.</li> |
| 145 | * </ul> |
| 146 | * |
| 147 | * <p>Here's a more complicated example, showing error handling, |
| 148 | * settings, and progress notification:</p> |
| 149 | * |
| 150 | * <pre class="prettyprint"> |
| 151 | * // Let's display the progress in the activity title bar, like the |
| 152 | * // browser app does. |
| 153 | * getWindow().requestFeature(Window.FEATURE_PROGRESS); |
| 154 | * |
| 155 | * webview.getSettings().setJavaScriptEnabled(true); |
| 156 | * |
| 157 | * final Activity activity = this; |
| 158 | * webview.setWebChromeClient(new WebChromeClient() { |
| 159 | * public void onProgressChanged(WebView view, int progress) { |
| 160 | * // Activities and WebViews measure progress with different scales. |
| 161 | * // The progress meter will automatically disappear when we reach 100% |
| 162 | * activity.setProgress(progress * 1000); |
| 163 | * } |
| 164 | * }); |
| 165 | * webview.setWebViewClient(new WebViewClient() { |
| 166 | * public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { |
| 167 | * Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show(); |
| 168 | * } |
| 169 | * }); |
| 170 | * |
| 171 | * webview.loadUrl("http://slashdot.org/"); |
| 172 | * </pre> |
| 173 | * |
| 174 | * <h3>Cookie and window management</h3> |
| 175 | * |
| 176 | * <p>For obvious security reasons, your application has its own |
| 177 | * cache, cookie store etc - it does not share the Browser |
| 178 | * applications data. Cookies are managed on a separate thread, so |
| 179 | * operations like index building don't block the UI |
| 180 | * thread. Follow the instructions in {@link android.webkit.CookieSyncManager} |
| 181 | * if you want to use cookies in your application. |
| 182 | * </p> |
| 183 | * |
| 184 | * <p>By default, requests by the HTML to open new windows are |
| 185 | * ignored. This is true whether they be opened by JavaScript or by |
| 186 | * the target attribute on a link. You can customize your |
| 187 | * WebChromeClient to provide your own behaviour for opening multiple windows, |
| 188 | * and render them in whatever manner you want.</p> |
| 189 | * |
| 190 | * <p>Standard behavior for an Activity is to be destroyed and |
| 191 | * recreated when the devices orientation is changed. This will cause |
| 192 | * the WebView to reload the current page. If you don't want that, you |
| 193 | * can set your Activity to handle the orientation and keyboardHidden |
| 194 | * changes, and then just leave the WebView alone. It'll automatically |
| 195 | * re-orient itself as appropriate.</p> |
