小结： 当我们需要在一个界面中处理很多事情的时候，可以推荐使用fragment，因为他会把我们的activity分割成很多小块，每个小块都有他的生命周期，非常方便，而有时我们会用单例模式来存储每个页面都有的东西。

项目的效果图

项目结构目录

代码具体编写

1、标题栏的布局界面，title_view.xml：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="50dip"

    android:background="@drawable/title_bg"

    android:orientation="horizontal" >

    <Button

        android:id="@+id/left_btn"

        style="@style/Text.Title_Button"

        android:layout_width="wrap_content"

        android:layout_height="35dip"

        android:layout_gravity="center_vertical"

        android:background="@drawable/title_btn_back"

        android:minWidth="60dip" />

    <TextView

        android:id="@+id/title_text"

        style="@style/Text.Title"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_gravity="center_vertical"

        android:layout_weight="" />

    <Button

        android:id="@+id/right_btn"

        style="@style/Text.Title_Button"

        android:layout_width="wrap_content"

        android:layout_height="35dip"

        android:layout_gravity="center_vertical"

        android:background="@drawable/title_btn"

        android:minWidth="70dip" />

</LinearLayout>

2、首页的fragment页面，这里就列出一个，fragment_home.xml：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

    <com.eoe.tampletfragment.view.TitleView

        android:id="@+id/title"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content" />

    <TextView

        android:id="@+id/fragment_home_text"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="@string/fragment_home_text"

        android:textSize="18sp" />

</LinearLayout>

3、帮助Activity界面，activity_help.xml：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:background="@drawable/activity_bg"

    android:orientation="vertical" >

    <com.eoe.tampletfragment.view.TitleView

        android:id="@+id/title"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content" />

</LinearLayout>

4、主页面布局，activity_main.xml：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:background="@drawable/activity_bg"

    android:orientation="vertical" >

    <fragment

        android:id="@+id/fragment_home"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent"

        android:layout_weight=""

        class="com.eoe.tampletfragment.fragment.HomeFragment" />

    <fragment

        android:id="@+id/fragment_search"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent"

        android:layout_weight=""

        class="com.eoe.tampletfragment.fragment.SearchFragment" />

    <fragment

        android:id="@+id/fragment_settings"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent"

        android:layout_weight=""

        class="com.eoe.tampletfragment.fragment.SettingsFragment" />

    <com.eoe.tampletfragment.fragment.FragmentIndicator

        android:id="@+id/indicator"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:background="@drawable/tab_footer_bg" />

</LinearLayout>

详细说明：  <1> 主页面MainActivity继承自FragmentActivity类，负责实现导航按钮所对应页面的显示和隐藏。
（详细实现见源码）
  <2> 主页面由底部导航栏和面板组成。  <3> fragment标签所对应Fragment的实现类。
  <4> com.eoe.tampletfragment.fragment.FragmentIndicator标签所对应的是底部导航栏。
5、自定义顶部工具栏，TitleView.java：

package com.eoe.tampletfragment.view;

import android.content.Context;

import android.util.AttributeSet;

import android.view.LayoutInflater;

import android.view.View;

import android.widget.Button;

import android.widget.FrameLayout;

import com.eoe.tampletfragment.R;

/**

                mOnRightButtonClickListener = listener;

        }

        public void setRightButton(int stringID, OnRightButtonClickListener listener) {

        }

        public TitleView(Context context) {

                this(context, null);

        }

        public TitleView(Context context, AttributeSet attrs) {

                this(context, attrs, );

        }

        public TitleView(Context context, AttributeSet attrs, int defStyle) {

                super(context, attrs, defStyle);

                LayoutInflater inflater = (LayoutInflater) context

                                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

                inflater.inflate(R.layout.title_view, this, true);

                mLeftBtn = (Button) findViewById(R.id.left_btn);

                mLeftBtn.setVisibility(View.INVISIBLE);

                mLeftBtn.setOnClickListener(this);

                }

        }
