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

<"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; } }
