Mike Hearn | adcd2ed | 2009-01-21 16:44:36 +0100 | [diff] [blame] | 95 | * <h3>Basic usage</h3> |
| 96 | * |
| 97 | * <p>By default, a WebView provides no browser-like widgets, does not |
Scott Main | 8b3cea0 | 2010-05-14 14:12:43 -0700 | [diff] [blame] | 98 | * enable JavaScript and web page errors are ignored. If your goal is only |
Mike Hearn | adcd2ed | 2009-01-21 16:44:36 +0100 | [diff] [blame] | 99 | * to display some HTML as a part of your UI, this is probably fine; |
| 100 | * the user won't need to interact with the web page beyond reading |
| 101 | * it, and the web page won't need to interact with the user. If you |
Scott Main | 8b3cea0 | 2010-05-14 14:12:43 -0700 | [diff] [blame] | 102 | * actually want a full-blown web browser, then you probably want to |
| 103 | * invoke the Browser application with a URL Intent rather than show it |
| 104 | * with a WebView. For example: |
| 105 | * <pre> |
Andrew Solovay | 5114257 | 2017-05-05 16:55:43 -0700 | [diff] [blame] | 106 | * Uri uri = Uri.parse("https://www.example.com"); |
Scott Main | 8b3cea0 | 2010-05-14 14:12:43 -0700 | [diff] [blame] | 107 | * Intent intent = new Intent(Intent.ACTION_VIEW, uri); |
| 108 | * startActivity(intent); |
| 109 | * </pre> |
Nate Fischer | f02f846 | 2017-09-11 15:16:33 -0700 | [diff] [blame] | 110 | * <p>See {@link android.content.Intent} for more information. |
Mike Hearn | adcd2ed | 2009-01-21 16:44:36 +0100 | [diff] [blame] | 111 | * |
Neil Fuller | 71fbb81 | 2015-11-30 09:51:33 +0000 | [diff] [blame] | 112 | * <p>To provide a WebView in your own Activity, include a {@code <WebView>} in your layout, |
Scott Main | 8b3cea0 | 2010-05-14 14:12:43 -0700 | [diff] [blame] | 113 | * or set the entire Activity window as a WebView during {@link |

| 222 | * <h3>Building web pages to support different screen densities</h3> |
| 223 | * |
| 224 | * <p>The screen density of a device is based on the screen resolution. A screen with low density |
| 225 | * has fewer available pixels per inch, where a screen with high density |
Brad Fitzpatrick | 438d059 | 2010-06-10 12:19:19 -0700 | [diff] [blame] | 226 | * has more — sometimes significantly more — pixels per inch. The density of a |
Scott Main | 8b3cea0 | 2010-05-14 14:12:43 -0700 | [diff] [blame] | 227 | * screen is important because, other things being equal, a UI element (such as a button) whose |
| 228 | * height and width are defined in terms of screen pixels will appear larger on the lower density |
| 229 | * screen and smaller on the higher density screen. |
| 230 | * For simplicity, Android collapses all actual screen densities into three generalized densities: |
Nate Fischer | f02f846 | 2017-09-11 15:16:33 -0700 | [diff] [blame] | 231 | * high, medium, and low. |
Scott Main | 8b3cea0 | 2010-05-14 14:12:43 -0700 | [diff] [blame] | 232 | * <p>By default, WebView scales a web page so that it is drawn at a size that matches the default |
| 233 | * appearance on a medium density screen. So, it applies 1.5x scaling on a high density screen |
| 234 | * (because its pixels are smaller) and 0.75x scaling on a low density screen (because its pixels |
| 235 | * are bigger). |
Steve Block | b838aef | 2012-04-23 18:22:15 +0100 | [diff] [blame] | 236 | * Starting with API level {@link android.os.Build.VERSION_CODES#ECLAIR}, WebView supports DOM, CSS, |
| 237 | * and meta tag features to help you (as a web developer) target screens with different screen |
Nate Fischer | f02f846 | 2017-09-11 15:16:33 -0700 | [diff] [blame] | 238 | * densities. |
| 239 | * <p>Here's a summary of the features you can use to handle different screen densities: |
Scott Main | 8b3cea0 | 2010-05-14 14:12:43 -0700 | [diff] [blame] | 240 | * <ul> |
| 241 | * <li>The {@code window.devicePixelRatio} DOM property. The value of this property specifies the |
| 242 | * default scaling factor used for the current device. For example, if the value of {@code |
| 243 | * window.devicePixelRatio} is "1.0", then the device is considered a medium density (mdpi) device |
| 244 | * and default scaling is not applied to the web page; if the value is "1.5", then the device is |
| 245 | * considered a high density device (hdpi) and the page content is scaled 1.5x; if the |
| 246 | * value is "0.75", then the device is considered a low density device (ldpi) and the content is |
Jonathan Dixon | 89f48e9 | 2013-02-27 16:42:48 -0800 | [diff] [blame] | 247 | * scaled 0.75x.</li> |
Scott Main | 8b3cea0 | 2010-05-14 14:12:43 -0700 | [diff] [blame] | 248 | * <li>The {@code -webkit-device-pixel-ratio} CSS media query. Use this to specify the screen |
| 249 | * densities for which this style sheet is to be used. The corresponding value should be either |
| 250 | * "0.75", "1", or "1.5", to indicate that the styles are for devices with low density, medium |
| 251 | * density, or high density screens, respectively. For example: |
| 252 | * <pre> |
| 253 | * <link rel="stylesheet" media="screen and (-webkit-device-pixel-ratio:1.5)" href="hdpi.css" /></pre> |
Andrew Solovay | 4ea753f | 2018-03-12 15:11:50 -0700 | [diff] [blame] | 254 | * <p>The {@code hdpi.css} stylesheet is only used for devices with a screen pixel ratio of 1.5, |
Nate Fischer | f02f846 | 2017-09-11 15:16:33 -0700 | [diff] [blame] | 255 | * which is the high density pixel ratio. |

| 271 | * {@link WebChromeClient#getVideoLoadingProgressView()} to customize the View displayed whilst a video |

| 287 | * {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT}. |
| 288 | * When using {@link android.view.ViewGroup.LayoutParams#MATCH_PARENT} |
| 289 | * for the height none of the WebView's parents should use a |
| 290 | * {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT} layout height since that could result in |
| 291 | * incorrect sizing of the views. |

| 2858 | * {@inheritDoc} |
| 2859 | * |
| 2860 | * <p>The {@link ViewStructure} traditionally represents a {@link View}, while for web pages |
| 2861 | * it represent HTML nodes. Hence, it's necessary to "map" the HTML properties in a way that is |
| 2862 | * understood by the {@link android.service.autofill.AutofillService} implementations: |
| 2863 | * |
| 2864 | * <ol> |
Felipe Leme | 303b609 | 2017-07-31 18:01:15 -0700 | [diff] [blame] | 2865 | * <li>Only the HTML nodes inside a {@code FORM} are generated. |
| 2866 | * <li>The source of the HTML is set using {@link ViewStructure#setWebDomain(String)} in the |
| 2867 | * node representing the WebView. |
| 2868 | * <li>If a web page has multiple {@code FORM}s, only the data for the current form is |
| 2869 | * represented—if the user taps a field from another form, then the current autofill |
| 2870 | * context is canceled (by calling {@link android.view.autofill.AutofillManager#cancel()} and |
| 2871 | * a new context is created for that {@code FORM}. |
| 2872 | * <li>Similarly, if the page has {@code IFRAME} nodes, they are not initially represented in |
| 2873 | * the view structure until the user taps a field from a {@code FORM} inside the |
| 2874 | * {@code IFRAME}, in which case it would be treated the same way as multiple forms described |
| 2875 | * above, except that the {@link ViewStructure#setWebDomain(String) web domain} of the |
| 2876 | * {@code FORM} contains the {@code src} attribute from the {@code IFRAME} node. |
Felipe Leme | 1a1e468 | 2017-03-13 16:34:03 -0700 | [diff] [blame] | 2877 | * <li>The W3C autofill field ({@code autocomplete} tag attribute) maps to |
Felipe Leme | 58390fe | 2017-09-15 15:16:28 -0700 | [diff] [blame] | 2878 | * {@link ViewStructure#setAutofillHints(String[])}. |
| 2879 | * <li>If the view is editable, the {@link ViewStructure#setAutofillType(int)} and |
Felipe Leme | 6dcec87 | 2017-05-25 11:24:23 -0700 | [diff] [blame] | 2880 | * {@link ViewStructure#setAutofillValue(AutofillValue)} must be set. |
Felipe Leme | 1a1e468 | 2017-03-13 16:34:03 -0700 | [diff] [blame] | 2881 | * <li>The {@code placeholder} attribute maps to {@link ViewStructure#setHint(CharSequence)}. |
Felipe Leme | 25bf787 | 2017-03-28 15:32:29 -0700 | [diff] [blame] | 2882 | * <li>Other HTML attributes can be represented through |
| 2883 | * {@link ViewStructure#setHtmlInfo(android.view.ViewStructure.HtmlInfo)}. |
Felipe Leme | 1a1e468 | 2017-03-13 16:34:03 -0700 | [diff] [blame] | 2884 | * </ol> |

Felipe Leme | 58390fe | 2017-09-15 15:16:28 -0700 | [diff] [blame] | 2886 | * <p>If the WebView implementation can determine that the value of a field was set statically |
| 2887 | * (for example, not through Javascript), it should also call |
| 2888 | * {@code structure.setDataIsSensitive(false)}. |
