Android开发人员：我如何提取网页数据，并使用这些数据在我的应用程序？ [英] Android Dev: How do I extract data from the web and use the data in my app?
问题描述
我看到这个Android应用程序称为歌词应用程序。它提供了当前播放歌曲的歌词，但需要互联网连接始终。现在，我想做一个类似的应用程序，它会从网上首次歌词，然后将其保存到我的Android设备，以便下一次歌曲播放，它会从设备的歌词，而不是网络的..不再需要不断的互联网连接。
I saw this android app called Lyrics App. It provides the lyrics of the song currently played but needs internet connection always. Now, I wanted to make a similar app, that it gets the lyrics from the web for the first time and then saves it to my android device, so that next time a song is played, it'll get the lyrics from the device instead of the web.. no need for constant internet connection.
我已经搜查，但我无法找到合适的人对我的情况。我检查web视图，但我认为这只是用于显示的WebContent，没有解压。
I've searched already but I can't find the right one for my case. I checked webview, but I think it's just for displaying webcontent, not extracting.
我是新来这个，所以请多多包涵。
I am new to this, so please bear with me.
推荐答案
试试...
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://www.someplace.com");
ResponseHandler<String> resHandler = new BasicResponseHandler();
String page = httpClient.execute(httpGet, resHandler);
这可以用来抓取整个网页作为一个字符串的HTML，即＆LT; HTML＆GT; ...＆LT; / HTML＆gt;中
This can be used to grab the whole webpage as a string of html, i.e., "<html>...</html>"
编辑：注意，你需要声明下面的使用，允许在Android清单xml文件...
Note, you need to declare the following 'uses-permission' in the android manifest xml file...
<uses-permission android:name="android.permission.INTERNET" />
