Fragment+FragmentTabHost组件实现常见主页面（仿微信新浪）

采取的方法是Fragment+FragmentTabHost组件来实现这种常见的app主页面的效果

首先给出main.xml文件

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="vertical" android:layout_width="match_parent"
     android:layout_height="match_parent">
     <FrameLayout
         android:id="@+id/realtabcontent"
         android:layout_width="fill_parent"
         android:layout_height="0dip"
         android:layout_weight="1"
         android:background="@color/white" />

     <LinearLayout
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:layout_gravity="bottom"
         android:orientation="vertical">

         <View
             android:layout_width="match_parent"
             android:layout_height="1px"
             android:background="@color/color_home_tab_line" />

         <android.support.v4.app.FragmentTabHost
             android:id="@android:id/tabhost"
             android:layout_width="fill_parent"
             android:layout_height="wrap_content"
             android:background="@color/et_divider_disable">

             <FrameLayout
                 android:id="@android:id/tabcontent"
                 android:layout_width="0dp"
                 android:layout_height="0dp"
                 android:layout_weight="0" />
         </android.support.v4.app.FragmentTabHost>

     </LinearLayout>
 </LinearLayout>

主代码：

 public class MainActivity
 {  @ViewInject(android.R.id.tabhost)
     private FragmentTabHost mTabHost;
 private LayoutInflater layoutInflater;

 private int mImageViewArray[] = {R.drawable.home_tab1, R.drawable.home_tab2, R.drawable.home_tab3, R.drawable.home_tab4};
     private String mTextviewArray[] = {"首页", "圈子", "资讯","个人中心"};
     private Class fragmentArray[] = {Fragment1.class, Fragment2.class, Fragment3.class,Fragment4.class};

  protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         init()；
     }

 @Override
     protected void init() {
 //        list=new JSONArray();
         layoutInflater=LayoutInflater.from(this);
         initTabHost();//初始化底部菜单
 }

  /**
      * 初始化底部工具栏
      */
     private void initTabHost() {
         mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
         mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
         int count = fragmentArray.length;
         for (int i = 0; i < count; i++) {
             TabHost.TabSpec tabSpec = mTabHost.newTabSpec(mTextviewArray[i])
                     .setIndicator(getTabItemView(i));
             mTabHost.addTab(tabSpec, fragmentArray[i], null);
             mTabHost.getTabWidget().getChildAt(i)
                     .setBackgroundResource(R.color.white);
         }
         mTabHost.setCurrentTabByTag(mTextviewArray[0]);
         mTabHost.getTabWidget().setDividerDrawable(null);
 }

   /**
      * 项的样式
      * @param index 第几个
      * @return 每一个Tab样式
      */
     private View getTabItemView(int index) {
         View view = layoutInflater.inflate(R.layout.tab_home_item, null);
         ImageView imageView = (ImageView) view.findViewById(R.id.icon);
         imageView.setImageResource(mImageViewArray[index]);
         TextView textView = (TextView) view.findViewById(R.id.name);
         textView.setText(mTextviewArray[index]);
         return view;
     }

 }

就ok啦！
