Android——“i 分享”APP開發Day02

設計my_tab_content.xml即“我的”Tab對應的頁面

採用相對佈局RelativeLayout，頂部是LinearLayout用於放頭像和用戶信息或者登陸、註冊按鈕
主要內容部分是ScrollView，放“我的”頁面的主要功能，在這裏我暫時分爲兩個區分別是“關於設置”和“關於我的”，在設置下有賬號管理、更新簽名、修改密碼三項；我的下面有趣事分享、日記分享、我的收藏和關於I分享這四個模塊，後期的功能也可以在這裏補充
設置頭部除了頭像剩餘的LinearLayout都爲隱藏狀態（如左下圖），在tab事件發生時根據登陸狀態做相應的隱藏和顯示（如右下圖）

——my_tab_content.xml頁面代碼初步如下

處理登錄、註冊相關邏輯——MyTabFragment.java

定義方法changStatus()對登錄狀態顯示不同的UI ，用SharePreferences記錄用戶的登錄狀態，如果已經登錄則顯示用戶頭像和相關信息，否則顯示註冊登錄按鈕

//根據狀態顯示或隱藏“我的”頁面中頭部信息
public void changeStatus(){
    //獲取最新的登錄狀態，SharePreferences爲永久存儲，需要手動退出
    SharedPreferences sp = mActivity.getSharedPreferences("save", Context.MODE_PRIVATE);
    isLogin = sp.getBoolean("isLogin",false);

    if(isLogin){
        Bitmap one;
        userName = sp.getString("name","");
        signature = sp.getString("sign","");
        headImg = sp.getString("headImg","");
        //設置用戶暱稱、頭像、心情
        my_name.setText(userName);
        my_sign.setText(userName);

        //通過網絡鏈接獲取圖片
        try {
            one= LoadImgByNet.getBitmap(imgBaseUrl+"my_tab_list1.png");
            my_head_img.setImageBitmap(one);
        }catch(IOException e){
            e.printStackTrace();
        }

        //已經登錄時設置用戶相關信息爲顯示狀態
        //username = this.getActivity().getSharedPreferences("config", Context.MODE_PRIVATE).getString("fname", "");
        login_top.setVisibility(View.VISIBLE);
        un_login_top.setVisibility(View.GONE);
    }else{
        //尚未登錄，設置登錄、註冊按鈕爲顯示狀態
        un_login_top.setVisibility(View.VISIBLE);
        login_top.setVisibility(View.GONE);
    }
}

2.在myeclipse中創建項目iShareService爲android應用搭建web後臺服務

創建org.utils包，在包下面創建class文件JdbcUtils.java，在文件中做數據庫連接處理

   private static String password="";
   private static String driverName="com.mysql.jdbc.Driver";

   // static靜態代碼塊裏面代碼，會在類加載到內存的時候立刻執行
   static {
       //1.註冊驅動
       try {
           Class.forName(driverName);
       } catch (ClassNotFoundException e) {
           e.printStackTrace();
       }
   }

   /**
   * 獲取連接
   * @return
   * @throws SQLException
   */
   public static Connection getConnection() throws SQLException {
       //2.獲取連接
       Connection connection = DriverManager.getConnection(url, username, password);
       return connection;
   }


   public static void close(Connection connection,PreparedStatement prepareStatement,ResultSet resultSet) {
       //5.釋放資源 connection prepareStatement resultSet
       if(resultSet!=null) {
           try {
               resultSet.close();
           } catch (SQLException e) {
               e.printStackTrace();
           }
       }
       if(prepareStatement!=null) {
           try {
               prepareStatement.close();
           } catch (SQLException e) {
               e.printStackTrace();
           }
       }
       if(connection!=null) {
           try {
               connection.close();
           } catch (SQLException e) {
               e.printStackTrace();
           }
       }
   }

   public static void statementClose(Connection connection,Statement statement,ResultSet resultSet) {
       //5.釋放資源 connection prepareStatement resultSet
       if(resultSet!=null) {
           try {
               resultSet.close();
           } catch (SQLException e) {
               e.printStackTrace();
           }
       }
       if(statement!=null) {
           try {
               statement.close();
           } catch (SQLException e) {
               e.printStackTrace();
           }
       }
       if(connection!=null) {
           try {
               connection.close();
           } catch (SQLException e) {
               e.printStackTrace();
           }
       }
   }
}

Navicat連接我的mySql數據庫，創建數據庫ishare，在數據庫中創建user表，表的設計如下

創建myServlet.data包，在包下面創建Servlet用於接收用戶註冊請求——Register.java，第一步做數據測試，不封裝返回的用戶信息

package myServlet.data;

import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.PreparedStatement;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;

在myServlet.data下創建Servlet處理登錄請求——Login.java ，第一步做數據測試，不封裝返回的用戶信息

response.setCharacterEncoding("utf-8");
PrintWriter out = response.getWriter();


       String username = request.getParameter("username").trim();
       String password = request.getParameter("password").trim();
       String signature = "在這裏寫下你的心情吧！";
       username = handleString(username);

       }

       if(password == null) {

       }

      Connection connection = null;

3. 因爲要通過網絡獲取到用戶頭像資源，所以需要創建LoadImgByNet.java文件，對網絡圖片資源進行處理，代碼如下：

package com.example.discover;

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;

import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;

public class LoadImgByNet {
    public static Bitmap getBitmap(String path) throws IOException {
            URL url = new URL(path);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setConnectTimeout(5000);
            conn.setRequestMethod("GET");
            if (conn.getResponseCode() == 200){
                InputStream inputStream = conn.getInputStream();
                Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
                return bitmap;
            }
        return null;
    }
}

4.在Android項目的MyTabFragment.java中給註冊、登錄按鈕綁定事件

因爲要進行網絡請求所以要設置線程策略setVersion，以及在AndroidMainfest.xml中設置網絡訪問權限（<uses-permission android:name="android.permission.INTERNET"/>）
點擊註冊按鈕，彈出註冊框（關聯外部的佈局R.layout.activity_register），給對話款添加“註冊”按鈕，實現該註冊按鈕時需要處理對話框自動關閉的問題
點擊登錄按鈕，彈出登錄框（關聯外部的佈局R.layout.activity_login），同上述的註冊按鈕做相同處理。另外在登錄成功之後還需要修改登錄狀態並進行UI更新，這部分操作放在方法loginSuccess()中
處理對話框的取消按鈕事件

package com.example.discover;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.SharedPreferences;

    TextView my_name,my_sign;   //用戶暱稱和心情

    /*Button go_login,go_register;*/
    String userName,passWord,signature,headImg;   //存放用戶基本信息
    RelativeLayout login,register;    //註冊、登錄頁面
    LinearLayout login_top,un_login_top;    //“我的”頁面頂部兩種狀態下的佈局
    Activity mActivity;     //存放當前的activity
    TextView test3;  //用於返回測試信息

    String baseUrl = "http://10.0.2.2:8080/iShareService/servlet/";   //web服務器的地址
