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！
