Android 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;
  }

}
