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！
