Android社交系統----代碼結構

今天終於考完了！也該來把這篇博客寫完！不能留下空白！上一篇博客主要是介紹這個社交系統的界面和一下功能了！現在我們來看看怎麼實現這些界面或功能的！
首先：我們來看看項目 的目錄吧，這個項目是在myeclipse環境下開發的，

正如圖片中所看到的。按照不同的功能將代碼進行這樣的分包，好吧，這是我學Android以來一直的分包習慣，任何Android程序都又代碼一步一步的實現的，若是我每個部分的代碼都說一遍的話可能長篇大論，我就跳幾個有意義的代碼來說說，要是想要源碼的小伙伴，後面提供下載
首先來看看登錄模塊

通過登錄頁我們可以看到采用異步消息機制，在控件注解的地方用的是xutil，這樣可以節省開發時間！
下面來看看主界面

package com.xl.activity;

import com.example.xl.R;
import com.xl.fragment.HomeFragment;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.widget.Toast;
public class MainActivity extends FragmentActivity {
    private String              TAG1="HOME";
    public static String LOCATION_BCR = "location_bcr";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //根據唯一性標識獲得MenuFragment對象
        HomeFragment homeFragment=new HomeFragment();
        //開啟事物管理器
        getSupportFragmentManager().
        beginTransaction().
        replace
        (R.id.content_frame, 
                homeFragment,
                TAG1).commit();
    }
    private long firstTime;
    @Override
    public void onBackPressed() {

        if (System.currentTimeMillis() - firstTime < 3000) {
            finish();
        } else {
            firstTime = System.currentTimeMillis();
            Toast.makeText(this, "連續按兩次退出程序", Toast.LENGTH_LONG).show();
        }
    }

}

主界面提供2個功能，開啟freagment和控制返回按鈕，
下面就是重要的fragment了，在上面開啟四個viewpager，這樣功能樣的代碼就可以抽取了，提高代碼的復用。
