剛做了個demo用于解壓縮本地zip文件，并用webview顯示其中的一個html文件，直接上代碼，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");//此處加載解壓后的html內容
-
- }
-
- /*
- * 這個是解壓ZIP格式文件的方法
- *
- * @zipFileName：是傳進來你要解壓的文件路徑，包括文件的名字；
- *
- * @outputDirectory:選擇你要保存的路勁；
- *
- */
- 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();
-
- }
-
-
- }
其中我的abc.zip文件是放在sdcard中的，里面有2個文件，解壓后生成一個abc文件夾，文件夾下是解壓縮后的2個文件，我用一個webview直接指定加載了解壓后的一個html文件，做的比較粗糙，省去了文件存在判斷，掃描文件名、文件類型，main.xml文件也很簡單，通過上面代碼應該可以看出其中的控件，這里不再寫xml布局文件了。
