我正在尝试为我的活动实现Tab View.我收到一个错误.

java.lang.IllegalArgumentException:您必须指定一种创建选项卡指示符的方法

     Resources res = getResources(); // Resource object to get Drawables
        TabHost tabHost = getTabHost();  // The activity TabHost
        TabHost.TabSpec spec;  // Resusable TabSpec for each tab
        Intent intent;  // Reusable Intent for each tab

        // Create an Intent to launch an Activity for the tab (to be reused)
        intent = new Intent().setClass(this, MonthActivity.class);

        // Initialize a TabSpec for each tab and add it to the TabHost
        spec = tabHost.newTabSpec("Month")
                      .setContent(intent);
        tabHost.addTab(spec);

        // Do the same for the …

我想提取一个普通的zip文件,但它仍然失败.这是我现在使用的代码:

private File downloadPath = new File(Environment.getExternalStorageDirectory() + "/Test/file.zip");
private File unzipLoc = new File(Environment.getExternalStorageDirectory() + "/Test/");
        FileInputStream fin = new FileInputStream(downloadPath); 
        ZipInputStream zin = new ZipInputStream(fin);
        ZipEntry ze = null; 
        while ((ze = zin.getNextEntry()) != null) 
        { 
            FileOutputStream fout = new FileOutputStream(unzipLoc + ze.getName()); 
            for (int c = zin.read(); c != -1; c = zin.read()) 
            { 
                fout.write(c); 
            } 

            zin.closeEntry(); 
            fout.close(); 
        } 
        zin.close(); 

它在'zin.getNextEntry()'部分失败.错误:java.util.zip.ZipException:无法读取版本任何想法？谢谢!
