关于底部菜单是什么,我想没必要介绍了,在市场上的APP里太常见了,这里提供两种方式来实现。

记得之前写过几篇关于底部菜单实现的方法,有兴趣的朋友可以看看:

1、《安卓开发复习笔记——TabHost组件(一)(实现底部菜单导航)

2、《安卓开发复习笔记——TabHost组件(二)(实现底部菜单导航)

3、《安卓开发笔记——Fragment+FragmentTabHost组件(实现新浪微博底部菜单)

 

今天带来种相对更通俗易懂的写法,不再和过去一样去沿用TabHost了,这次我们直接用LinearLayout布局来实现,先来看下实现效果图:

中间内容区域有两种实现方式:

1、ViewPager  --可滑动界面      2、Fragment  --固定界面

1、界面分析

技术分享

 这里有个小技巧,把底部菜单栏的每一个小的LinearLayout的宽度都设置成0dp,然后用weight权重去分配它,中间内容区域也是把高度设置成0dp,然后用weight权重去分配它。(weight默认是把界面里空闲的位置作为划分位置,所以这里的宽度或者高度要注意设置成0dp)

 

2、具体实现(内容区域为ViewPager可滑动界面)

布局文件:

activity_top.xml(顶部布局)

 1 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     xmlns:tools="http://schemas.android.com/tools"
 3     android:layout_width="match_parent"
 4     android:layout_height="55dp"
 5     android:background="@drawable/title_bar">
 6 
 7     <TextView
 8         android:layout_width="wrap_content"
 9         android:layout_height="wrap_content"
10         android:layout_centerInParent="true"
11         android:text="微信"

具体实现代码:

ViewPager适配器(关于ViewPager的使用方法这里就不多说了,不清楚的朋友看我这篇文章吧《安卓开发笔记——ViewPager组件(仿微信引导界面)》)

 1 package com.rabbit.tabdemo;
 2 
 3 import java.util.List;
 4 
 5 import android.support.v4.view.PagerAdapter;
 6 import android.view.View;
 7 import android.view.ViewGroup;
 8 /**

10  * @author Balla_兔子
11  *
12  */
13 public class ContentAdapter extends PagerAdapter {
14 
15     private List<View> views;
16 
17     public ContentAdapter(List<View> views) {
18         this.views = views;
19     }
20 
21     @Override
22     public int getCount() {
23         return views.size();
24     }
25 
26     @Override
27     public boolean isViewFromObject(View arg0, Object arg1) {
28         return arg0 == arg1;
29     }
30 
31     @Override
32     public Object instantiateItem(ViewGroup container, int position) {
33         View view = views.get(position);
34         container.addView(view);
35         return view;
36     }
37 
38     @Override
39     public void destroyItem(ViewGroup container, int position, Object object) {
40         container.removeView(views.get(position));
41     }
42 
43 }

 

MainActivity(主界面代码)

初始化控件后,完成对底部菜单的4个LinearLayout的点击监听事件,在用户触发点击事件的时候,设置选择状态然后跳转相对应的界面。为了使得滑动ViewPager也能同时触发底部菜单状态的改变,这里也对ViewPager设置了滑动监听。其他的代码注释很全,看注释就可以了。

187         }
188         
189     }

191 }

 

3、具体实现(内容区域为Fragment固定界面)

布局文件:

布局文件基本没变化,只是把主界面的ViewPager改成了FramLayout,其他文件保持一致,就不贴出来了。

14         android:layout_weight="1" >
15     </FrameLayout>
16 
17     <include layout="@layout/activity_bottom" />
18 
19 </LinearLayout>

具体实现代码:

由于这次的内容是基于Fragment的,所以需要有4个Fragment文件,由于代码相同这里只贴出一个。

Frgament(HomeFragment,AddressFragment,FriendFragment,SettingFragment)

MainActivity(主界面代码)

代码很简单,一看就能明白就不多说什么了,只提个需要注意的地方,由于便于向下兼容这里的Fragment是用V4包下的,在导入包的时候需要注意一下。

总结:

基于ViewPager实现的内容:

优点:

1、界面可以滑动,美观,流畅。

缺点:

1、当界面里有一些需要用手势来实现的内容会起冲突,比如我们ListView里的侧滑删除。

2、由于采用的是ViewPager,所以页面内容实现代码会严重依赖于MainActivity,代码太过冗余,不便于后期维护。

 

基于Fragment实现的内容:

优点:

1、Fragment文件单独存在,各自页面的内容各自去实现完成,有自己的生命周期,便于后期维护。

2、对于需要手势操作的一些内容不会起冲突。

缺点:

1、界面不可滑动,比较死板。
