servlet將html表單寫入Android

我想將servlet的輸出寫入android活動。但在活動中，我只獲取html數據流。我如何在Android中顯示html網頁顯示？servlet將html表單寫入Android

NewServlet.java

@WebServlet(name = "NewServlet", urlPatterns = {"/NewServlet"}) 
    public class NewServlet extends HttpServlet { 


    protected void processRequest(HttpServletRequest request, HttpServletResponse response) 
      throws ServletException, IOException { 
     response.setContentType("text/html;charset=UTF-8"); 
     try (PrintWriter out = response.getWriter()) { 
      /* TODO output your page here. You may use following sample code. */ 
      out.println("<html>\n" + 
      " <body>\n" + 
      "  <input type=\"submit\" value=\"click me\" />\n" + 
      " </body>\n" + 
      "</html>"); 
     } 
    } 

    @Override 
    protected void doGet(HttpServletRequest request, HttpServletResponse response) 
      throws ServletException, IOException { 
     processRequest(request, response); 
    } 


    @Override 
    protected void doPost(HttpServletRequest request, HttpServletResponse response) 
      throws ServletException, IOException { 
     processRequest(request, response); 
    } 


    @Override 
    public String getServletInfo() { 
     return "Short description"; 
    }// </editor-fold> 

}

activity_main.xml中

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" 
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity"> 


    <TextView 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:textAppearance="?android:attr/textAppearanceLarge" 
     android:text="Large Text" 
     android:id="@+id/textView" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" 
     android:layout_marginTop="84dp" />

如果我理解正確的話，你要顯示的網頁本身，像一個瀏覽器。您無法使用文本視圖來完成此操作。您需要使用一個名爲WebView的組件。

這裏有一個簡單的例子：

<?xml version="1.0" encoding="utf-8"?> 
<WebView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/webpage" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
/> 

WebView webView = (WebView) findViewById(R.id.webpage); 
webView.loadUrl("http://10.11.55.45:8080/WebApplication3/NewServlet");
