主界面布局文件：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <FrameLayout        android:id="@+id/realtabcontent"        android:layout_width="fill_parent"        android:layout_height="0dip"        android:layout_weight="1" />    <android.support.v4.app.FragmentTabHost        android:id="@android:id/tabhost"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:background="@drawable/border"        >        <FrameLayout            android:id="@android:id/tabcontent"            android:layout_width="0dp"            android:layout_height="0dp"            android:layout_weight="0" />    </android.support.v4.app.FragmentTabHost></LinearLayout>

tab_item_view布局文件：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:gravity="center">    <ImageView        android:id="@+id/imageview"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:focusable="false"        android:padding="3dp"        android:src="@drawable/tab_home_pre">    </ImageView>    <TextView        android:id="@+id/textview"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="首页">    </TextView></LinearLayout>

主Activity中的部分代码：

package com.activity;import android.annotation.SuppressLint;import android.content.Intent;import android.graphics.Color;import android.os.Bundle;import android.support.v4.app.FragmentActivity;import android.support.v4.app.FragmentTabHost;import android.support.v4.app.FragmentTransaction;import android.util.Log;import android.view.KeyEvent;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;import android.view.Window;import android.widget.ImageButton;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.TabHost;import android.widget.TextView;import android.widget.Toast;import com.beidougd.bdgc.R;import com.umeng.update.UmengUpdateAgent;public class FragmentMainActivity extends FragmentActivity {    private ImageView imageView;private TextView textView;private long touchTime = 0;private static FragmentActivity activity;//定义FragmentTabHost对象private FragmentTabHost mTabHost;//定义一个布局private LayoutInflater layoutInflater;//定义数组来存放Fragment界面private Class fragmentArray[] = {TabHome.class,TabHistory.class,TabFind.class,TabSetting.class};//定义数组来存放按钮图片private int mImageViewArray[] = {R.drawable.tab_home_selector,R.drawable.tab_history_selector,R.drawable.tab_find_selector,R.drawable.tab_setting_selector};//Tab选项卡的文字private String mTextviewArray[] = {"首页", "历史", "发现", "设置"};@SuppressLint("NewApi") @Overrideprotected void onCreate(Bundle savedInstanceState) {requestWindowFeature(Window.FEATURE_NO_TITLE);super.onCreate(savedInstanceState);setContentView(R.layout.fragment_main);activity = this;initViews();UmengUpdateAgent.update(this);//接收通知打开历史界面getIntentandopenHistory();}private void initViews() {MyApplication.getIntance().addActivity(FragmentMainActivity.this);//实例化布局对象layoutInflater = LayoutInflater.from(this);//实例化TabHost对象，得到TabHostmTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);//得到fragment的个数int count = fragmentArray.length;for(int i = 0; i < count; i++) {//为每一个Tab按钮设置图标、文字和内容TabHost.TabSpec tabSpec = mTabHost.newTabSpec(mTextviewArray[i]).setIndicator(getTabItemView(i));//将Tab按钮添加进Tab选项卡中mTabHost.addTab(tabSpec, fragmentArray[i], null);
