简述:结构化描述intent匹配的信息。包含:action,categories and data(via type,scheme ,path),还有priority, to order multiple matching filters. IntentFilter 中如果action为空,则视为通配符,如果type为空,则intent必须不设type,否则匹配不上。 data被分为3个属性:type,scheme,authority/path 任何设置的属性intent必须匹配上。 设置了scheme 而没设type,则intent也必须类似,不能设置type,也不能是content: URI. 设置了type而没设scheme:将匹配上没有URI的intent,或者content:,file:的uri。 设置了authority:必须指定一个或多个相关联的schemes 设置了path:唏嘘指定一个或多个相关联的schemes 匹配规则: IntentFilter 匹配Intent的上的条件: Action : 值相同 ,或则IntentFilter未指定action. DataType:. 系统通过调用Intent.resolve(ContentResolver)获取type,通配符* 在Intent/IntentFilter的MIME type中使用,区分大小写 DataScheme:系统通过调用Intent. getData() and Uri.getScheme())获取scheme, 区分大小写 DataAuthority:必须有一个dataScheme匹配上且authority值匹配上,或者IntentFilter没有定义。Intent. getData() and Uri.getAuthority()获取authority. DataPath: scheme and authority必须先匹配上 ntent. getData() and Uri.getPath(),获取. 或者IntentFilter没有定义 Categories:all of the categories in the Intent match categories given in the filter 多余的Categorie,不影响intent匹配,如果IntentFilter 没有指定Categorie,则只能匹配上没有Categorie的intent。 常用intent列表: Android Intent 用法汇总 显示网页 - <activity android:name="BrowserActivity" android:label="Browser" android:launchMode="singleTask" android:alwaysRetainTaskState="true" android:configChanges="orientation|keyboardHidden" android:theme="@style/BrowserTheme"> - <!-- For these schemes were not particular MIME type has been supplied, we are a good candidate. --> - <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="http" /> <data android:scheme="https" /> <data android:scheme="about" /> </intent-filter> - <!-- For these schemes where any of these particular MIME types have been supplied, we are a good candidate. --> - <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.BROWSABLE" /> <category android:name="android.intent.category.DEFAULT" /> <data android:scheme="http" /> <data android:scheme="https" /> <data android:mimeType="text/html" /> <data android:mimeType="text/plain" /> <data android:mimeType="application/xhtml+xml" /> <data android:mimeType="application/vnd.wap.xhtml+xml" /> </intent-filter> - <!-- We are also the main entry point of the browser. --> - <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.LAUNCHER" /> <category android:name="android.intent.category.BROWSABLE" /> </intent-filter> - <intent-filter> <action android:name="android.intent.action.WEB_SEARCH" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="" /> <data android:scheme="http" /> <data android:scheme="https" /> </intent-filter> - <intent-filter> <action android:name="android.intent.action.WEB_SEARCH" /> <action android:name="android.intent.action.MEDIA_SEARCH" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> - <intent-filter> <action android:name="android.intent.action.SEARCH" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> <meta-data android:name="android.app.searchable" android:resource="@xml/searchable" /> - <intent-filter> <action android:name="android.net.http.NETWORK_STATE" /> <action android:name="android.intent.action.PROXY_CHANGE" /> </intent-filter> </activity> 1.
