刚做了个demo用于解压缩本地zip文件,并用webview显示其中的一个html文件,直接上代码,需要的朋友可以看看
public class ZipActivity extends Activity { private static final String TAG = "HelloXmlActivity"; private WebView mWebView; private static LinkedHashMap<String, String> widgetInfoMap = new LinkedHashMap<String, String>(); //http://blog.csdn.net/com360/article/details/6618086 /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); String zipfile = "/sdcard/abc.zip"; try { unzip(zipfile, "/sdcard/");//yangguangfu/wujiali/ } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } mWebView=(WebView)findViewById(R.id.web); mWebView.loadUrl("file:///sdcard/abc/aaa.html");//此处加载解压后的html内容 } /* * 这个是解压ZIP格式文件的方法 * * @zipFileName:是传进来你要解压的文件路径,包括文件的名字; * * @outputDirectory:选择你要保存的路劲; * */ private void unzip(String zipFileName, String outputDirectory) throws Exception { ZipInputStream in = new ZipInputStream(new FileInputStream(zipFileName)); ZipEntry z; String name = ""; String extractedFile = ""; int counter = 0; while ((z = in.getNextEntry()) != null) { name = z.getName(); Log.d(TAG, "unzipping file: " + name); if (z.isDirectory()) { Log.d(TAG, name + "is a folder"); // get the folder name of the widget name = name.substring(0, name.length() - 1); File folder = new File(outputDirectory + File.separator + name); folder.mkdirs(); if (counter == 0) { extractedFile = folder.toString(); } counter++; Log.d(TAG, "mkdir " + outputDirectory + File.separator + name); } else { Log.d(TAG, name + "is a normal file"); File file = new File(outputDirectory + File.separator + name); file.createNewFile(); // get the output stream of the file FileOutputStream out = new FileOutputStream(file); int ch; byte[] buffer = new byte[1024]; // read (ch) bytes into buffer while ((ch = in.read(buffer)) != -1) { // write (ch) byte from buffer at the position 0 out.write(buffer, 0, ch); out.flush(); } out.close(); } } in.close(); } }Android程序解压缩zip文件并加载显示解压后的文件
