Android程式解壓縮zip檔案，並載入顯示解壓後的檔案內容

剛做了個demo用於解壓縮本地zip檔案，並用webview顯示其中的一個html檔案，直接上程式碼，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");//此處載入解壓後的html內容

	}

	/*
	 * 這個是解壓ZIP格式檔案的方法
	 * 
	 * @zipFileName：是傳進來你要解壓的檔案路徑，包括檔案的名字；
	 * 
	 * @outputDirectory:選擇你要儲存的路勁；
	 * 
	 */
	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檔案是放在sdcard中的，裡面有2個檔案，解壓後生成一個abc資料夾，資料夾下是解壓縮後的2個檔案，我用一個webview直接指定載入瞭解壓後的一個html檔案，做的比較粗糙，省去了檔案存在判斷，掃描檔名、檔案型別，main.xml檔案也很簡單，通過上面程式碼應該可以看出其中的控制元件，這裡不再寫xml佈局檔案了。
