        android:layout_height="fill_parent"
        android:background="#ffffff" />

</LinearLayout>

　　效果图如下：

item.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    android:layout_width="match_parent"
	android:layout_height="wrap_content"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <ImageView
        android:id="@+id/itemImage"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:src="@drawable/ic_launcher"
        android:layout_alignParentLeft="true"

        />
    <TextView
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="前段时间做了一个与LBS有关的项目"
        android:layout_toRightOf="@+id/itemImage"
        android:layout_centerVertical="true"
        />

</RelativeLayout>

　　lay1.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"
     >
     <TextView
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:text="第一页"
         android:gravity="center"
         />
     <Button
         android:id="@+id/confirm"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:layout_marginLeft="2dp"
         android:layout_marginRight="2dp"
         android:text="确定"
         />
     <Button
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:layout_marginLeft="2dp"
         android:layout_marginRight="2dp"
         android:text="分享"
         />
     <Button
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:layout_marginLeft="2dp"
         android:layout_marginRight="2dp"
         android:text="浏览"
         />
     <Button
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:layout_marginLeft="2dp"
         android:layout_marginRight="2dp"
         android:text="取消"
         />

</LinearLayout>

　　lay02.xml，lay03.xml除了最顶端设置的页码不一样，其他都一直，所以之类就不放上其对应的xml了。

lay04:

<?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"
     >
   <ListView
       android:id="@+id/mylistview"
       android:layout_width="fill_parent"
       android:layout_height="fill_parent"
       />  

</LinearLayout>

　　最终做出来的效果图：

Android——ViewPager+Fragment+ListView之间

Android--ViewPager+Fragment+ListView之间 <span style="font-size:18px;">package com.example.jreduch05; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.view.ViewPager; import android.support.v7.app.A

在Fragment中加一个嵌套了ListView的ScrollView（一）

首先介绍一下这个程序的功能: 1.顶部有两个可以切换Fragment的Button 2.在其中一个Fragment中里有个ScrollView,ScrollView中有ViewFlipper,ListView.(另一个Fragment中就随意了) 随着listView的滚动,ViewFlipper中的内容也会滚动. 3.两个布局(主布局,一个Fragment的布局(另一个没写,其实都一样)),一个Fragment,一个主Activity,重写ListView(不重写的话,不会随着ViewFlip

Fragment中添加ListView而不使用ListFragment

最初的构想是,将Fragment和ViewPager结合起来, 然后突发奇想,在第一个Fragment里添加了ListView, 依照网上的建议,extends了ListFragment,接着各种报错. 仔细看了下,原来是MainActivity这里: 1 //构造适配器 2 List<Fragment> fragments=new ArrayList<Fragment>(); 3 fragments.add(new Fragment1()); 4 fragments.add(ne

---恢复内容开始--- 结果截图如下: 第一张图是程序主界面,主要是显示记事列表的一些个事件.旁边的侧拉框是自己登陆用的.可以设置密码.可以查看反馈与关于等信息. 点击第一张图片下方的图标,会显示不同的内容,分别如下: 这四张图分别是添加心情,统计心情记录,设置闹铃,开启音乐.分别对应  添加心情模块.统计心情记录模块.铃声提醒模块.音乐播放器模块 按我的想法,此款app主要用来记录心情,而且可以边播放音乐边写日志.而且,还可以通过闹铃提醒我们写日志.而且,还可以统计我们最近的心情状态,为及时
