这是个不错的教程，自己学完了之后就拿出来分享了，本来想一个帖子写完，但是发现这样对自己写博客的效率有点出入，而且吃了一次亏，大家看我的群英传第六章笔记就知道，到现在还没写完，实在是太长了，为了让大家看的舒服点，所以分开来写，我们先开看下百度壁纸的客户端是什么样子的



我们先来写个主页的框架，我们新建一个项目——BaiDuWallPaper



写个Item

layout_tab_item

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true">

<ImageView
android:id="@+id/tabImg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" />

<TextView
android:id="@+id/tabText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/tabImg"
android:layout_centerHorizontal="true"
android:text="@string/app_name"
android:textColor="@android:color/white"
android:textSize="16sp" />

</RelativeLayout>

</RelativeLayout>

然后我们再写个布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="70dp"
android:orientation="horizontal">

<include
android:id="@+id/homeLayout"
layout="@layout/layout_tab_item"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />

<include
android:id="@+id/selectLayout"
layout="@layout/layout_tab_item"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />

<include
android:id="@+id/searchLayout"
layout="@layout/layout_tab_item"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />

<include
android:id="@+id/locationLayout"
layout="@layout/layout_tab_item"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />

<include
android:id="@+id/settingLayout"
layout="@layout/layout_tab_item"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />

</LinearLayout>

这样我们就可以自定义组合控件了

TextView tvSetting4 = (TextView) settingLayout.findViewById(R.id.tabText);
tvSetting4.setTextColor(Color.BLUE);

break;
}
}
}

我们运行一下



接下来我们让他可以切换选项卡，我们定义一个接口

/**
* 切换页面的接口
*/
public interface ICallbackListener {
public void clic(int id);
}

ICallbackListener iCallbackListener = null;

public void setonCallbackListener(ICallbackListener iCallbackListener) {
this.iCallbackListener = iCallbackListener;
}

接着初始化数据

/**
* 设置默认的第一页数据
*/
private void initPagerContent(android.app.Fragment fragment) {
FragmentManager manager = getFragmentManager();
android.app.FragmentTransaction ft = manager.beginTransaction();
ft.replace(R.id.myContent,fragment);
ft.commit();
}

然后我们引用的时候就可以直接new了

/**
* 切换接口
*/
private class MyCallbackListener implements MyBottomLayout.ICallbackListener {

@Override
public void clic(int id) {
switch (id) {
case R.id.homeLayout:
initPagerContent(new HomeFragment());

break;
case R.id.selectLayout:
initPagerContent(new SelectFragment());

break;
case R.id.searchLayout:
initPagerContent(new SearchFragment());

break;
case R.id.locationLayout:
initPagerContent(new LoactionFragment());

break;
case R.id.settingLayout:
initPagerContent(new SettingFragment());

break;

}
}
}

我们在运行一下



但是有一点我们要知道，我们还要实现滑动，这样的话，我们就要使用viewpager了

layout_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.v4.view.ViewPager
android:id="@+id/myViewPager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="@+id/myBottomLayout" />

<com.lgl.baiduwallpaper.view.MyBottomLayout
android:id="@+id/myBottomLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="@mipmap/image_titlebar_background" />
</RelativeLayout>

具体的，我就直接把MainActivity的代码贴上吧

package com.lgl.baiduwallpaper;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;

import com.lgl.baiduwallpaper.fragment.HomeFragment;
import com.lgl.baiduwallpaper.fragment.LoactionFragment;
import com.lgl.baiduwallpaper.fragment.SearchFragment;
import com.lgl.baiduwallpaper.fragment.SelectFragment;
import com.lgl.baiduwallpaper.fragment.SettingFragment;
import com.lgl.baiduwallpaper.view.MyBottomLayout;

/**
* 主界面
*/
public class MainActivity extends FragmentActivity {

private MyBottomLayout myBottomLayout;
private ViewPager viewpager;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

initView();
}

/**
* 初始化
*/
private void initView() {
//        initPagerContent(new HomeFragment());
findView();
setOnclick();
}

//    /**
//     * 设置默认的第一页数据
//     */
//    private void initPagerContent(android.app.Fragment fragment) {
//        FragmentManager manager = getFragmentManager();
//        android.app.FragmentTransaction ft = manager.beginTransaction();
//        ft.replace(R.id.myContent,fragment);
//        ft.commit();
//    }

/**
* 点击事件
*/
private void setOnclick() {
myBottomLayout.setonCallbackListener(new MyCallbackListener());
}

/**
* 找寻控件
*/
private void findView() {
myBottomLayout = (MyBottomLayout) findViewById(R.id.myBottomLayout);

viewpager = (ViewPager) findViewById(R.id.myViewPager);
viewpager.setAdapter(new MyFragmentAdapter(getSupportFragmentManager()));
//页面监听
viewpager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

}

@Override
public void onPageSelected(int position) {
myBottomLayout.initPix(position);
}

@Override
public void onPageScrollStateChanged(int state) {

}
});
}

/**
* 切换接口
*/
private class MyCallbackListener implements MyBottomLayout.ICallbackListener {

@Override
public void clic(int id) {
switch (id) {
case R.id.homeLayout:
//                    initPagerContent(new HomeFragment());
viewpager.setCurrentItem(0);
break;
case R.id.selectLayout:
//                    initPagerContent(new SelectFragment());
viewpager.setCurrentItem(1);
break;
case R.id.searchLayout:
//                    initPagerContent(new SearchFragment());
viewpager.setCurrentItem(2);
break;
case R.id.locationLayout:
//                    initPagerContent(new LoactionFragment());
viewpager.setCurrentItem(3);
break;
case R.id.settingLayout:
//                    initPagerContent(new SettingFragment());
viewpager.setCurrentItem(4);
break;

}
}
}

/**
* viewpager的adapter
*/
private class MyFragmentAdapter extends FragmentPagerAdapter {

public MyFragmentAdapter(FragmentManager fm) {
super(fm);
}

@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new HomeFragment();
case 1:
return new SelectFragment();
case 2:
return new SearchFragment();
case 3:
return new LoactionFragment();
case 4:
return new SettingFragment();
}
return null;
}

@Override
public int getCount() {
//5个页面
return 5;
}
}
}

主要是你切换的时候setCurrentItem(id);同时监听viewpager的滑动，就可以自由切换了，我们运行一下



本来是想提供完整的Demo的，不过感觉这个框架已经许多人用得上，所以我就单独上传了
