Android中FragmentTabHost结合fragment实现选项卡功能

效果图：

下面直接上代码了，注释很全，看过我前2篇文章的朋友，肯定秒懂的，哈哈~
activity_main.xml（主布局文件）

<span style="font-size:18px;"><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <!-- 存放主要页面内容 -->    <FrameLayout        android:id="@+id/maincontent"        android:layout_width="fill_parent"        android:layout_height="0dp"        android:layout_weight="1" >    </FrameLayout>    <!-- 底层菜单 -->    <android.support.v4.app.FragmentTabHost        android:id="@android:id/tabhost"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:background="#99CC99" >        <FrameLayout            android:id="@android:id/tabcontent"            android:layout_width="0dp"            android:layout_height="0dp"            android:layout_weight="0" >        </FrameLayout>    </android.support.v4.app.FragmentTabHost></LinearLayout></span>

tabcontent.xml（具体底部菜单详细布局）

<span style="font-size:18px;"><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:gravity="center_horizontal"    android:orientation="vertical" >    <ImageView        android:id="@+id/image"        android:layout_height="30dp"        android:layout_width="30dp"        android:layout_gravity="center_horizontal"        />    <TextView        android:id="@+id/text"        android:padding="2dp"        android:layout_gravity="center_horizontal"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:textColor="@color/color"        /></LinearLayout></span>

Fragment有5个，都一样，这里只写一个，示范一下
注意Fragment是import android.support.v4.app.Fragment;包下的

<span style="font-size:18px;">public class BlankFragment1 extends Fragment {    public BlankFragment1() {        // Required empty public constructor    }    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container,                             Bundle savedInstanceState) {        // Inflate the layout for this fragment        return inflater.inflate(R.layout.fragment1, container, false);    }}</span>

fragment.xml(有5个，由于只有文字不同，这里只给出一个)fragment1.xml

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent">    <TextView        android:layout_width="match_parent"        android:layout_height="match_parent"        android:text="我的第1个fragment"        /></LinearLayout></span>

图片选择器，放在res---drawable目录下（有5个，内容都一样）这里只写一个selector_cart.xml

点击后改变图片

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:drawable="@mipmap/guide_cart_on" android:state_focused="true" />    <item android:drawable="@mipmap/guide_cart_on" android:state_selected="true" />    <item android:drawable="@mipmap/guide_cart_nm" /></selector></span>

文字选择器，放在res----color----color.xml,只有一个

点击后改变文字颜色

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:color="#FF5001" android:state_focused="true" />    <item android:color="#FF5001" android:state_selected="true" />    <item  android:color="@android:color/darker_gray" /></selector></span>

MainActivity.java（主代码）

注意MainActivity 必须继承FragmentActivity 

<span style="font-size:18px;">public class MainActivity extends FragmentActivity {    private FragmentTabHost fragmentTabHost;    private String texts[] = {"首页", "消息", "好友", "广场", "更多"};    private int imageButton[] = {R.drawable.selector_cart, R.drawable.selector_catagory, R.drawable.selector_hot, R.drawable.selector_personal, R.drawable.selector_tab};    private Class fragmentArray[] = {BlankFragment1.class, BlankFragment2.class, BlankFragment3.class, BlankFragment4.class, BlankFragment5.class};    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        // 实例化tabhost        fragmentTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);        fragmentTabHost.setup(this, getSupportFragmentManager(),                R.id.maincontent);        for (int i = 0; i < texts.length; i++) {            TabHost.TabSpec spec = fragmentTabHost.newTabSpec(texts[i]).setIndicator(getView(i));            fragmentTabHost.addTab(spec, fragmentArray[i], null);        }//      去掉分隔的竖线        fragmentTabHost.getTabWidget().setShowDividers(LinearLayout.SHOW_DIVIDER_NONE);    }    private View getView(int i) {        //取得布局实例        View view = View.inflate(MainActivity.this, R.layout.tabcontent, null);        //取得布局对象        ImageView imageView = (ImageView) view.findViewById(R.id.image);        TextView textView = (TextView) view.findViewById(R.id.text);        //设置图标        imageView.setImageResource(imageButton[i]);        //设置标题        textView.setText(texts[i]);        return view;    }}</span>

注意：这个方法把我的设置为点亮状态，并显示我的fragment

if (ConsumerApp.consumerApp.mainMy == 4) {    fragmentTabHost.setCurrentTabByTag("我的");}
