尽管google已经废弃了TabActivity..但是，用还是可以用的。话不多说，看代码

import android.app.TabActivity;import android.content.Intent;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.TabHost;import android.widget.TextView;/** * Created by Administrator on 2016/8/18. */public class MainTabActivity extends TabActivity {    private TextView textView;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main_tab_activity);        //  this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);       //Resources res = getResources();        final TabHost tabHost = getTabHost();        TabHost.TabSpec spec;        Intent intent;        //HomeActivity          intent = new Intent().setClass(this, HomeActivity.class);        spec = tabHost.newTabSpec("home").setIndicator(generateView("首页",R.drawable.tab_dashboard_selector)).setContent(intent);        tabHost.addTab(spec);        //CarControlActivity          intent = new Intent().setClass(this, ControlActivity.class);        spec = tabHost.newTabSpec("contrl").setIndicator(generateView("控制",R.drawable.tab_control_selector)).setContent(intent);        tabHost.addTab(spec);       //MapActivity         intent = new Intent().setClass(this, NavActivity.class);        spec = tabHost.newTabSpec("suiyi").setIndicator(generateView("随意",

R.drawable.tab_nav_selector)).setContent(intent);        tabHost.addTab(spec);       //SettingActivity         intent = new Intent().setClass(this, SettingActivity.class);        spec = tabHost.newTabSpec("set").setIndicator(generateView("设置", R.drawable.tab_mine_selector)).setContent(intent);        tabHost.addTab(spec);        tabHost.setCurrentTab(0);        for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {            TextView tv = (TextView) tabHost.getTabWidget().getChildAt(i).findViewById(R.id.name);            if (tabHost.getCurrentTab() == i) {//选中                tv.setTextColor(MainTabActivity.this.getResources().getColor(R.color.home_text_color_blue));            } else {//不选中                tv.setTextColor(MainTabActivity.this.getResources().getColor(R.color.home_text_color_gray));            }        }        tabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener() {            @Override            public void onTabChanged(String s) {                for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {                    TextView tv = (TextView) tabHost.getTabWidget().getChildAt(i).findViewById(R.id.name);                    if (tabHost.getCurrentTab() == i) {//选中                        tv.setTextColor(MainTabActivity.this.getResources().getColor(R.color.home_text_color_blue));                    } else {//不选中                        tv.setTextColor(MainTabActivity.this.getResources().getColor(R.color.home_text_color_gray));                    }            }            }        });    }    /**     * 生成每一个tab     * @param title     * @param icon     * @return     */    private View generateView(String title, int icon){        LinearLayout singleTab = (LinearLayout) LayoutInflater.from(this).inflate(R.layout.single_tab, null);        ImageView imgView = (ImageView)singleTab.findViewById(R.id.icon);        imgView.setBackgroundResource(icon);        textView = (TextView)singleTab.findViewById(R.id.name);        textView.setText(title);        textView.setTextColor(this.getResources().getColor(R.color.home_text_color_gray));        textView.setTextSize(12);        return singleTab;    }}

以下为single_tab.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:gravity="center_horizontal|center_vertical"    android:orientation="vertical" >    <LinearLayout        android:id="@+id/ll"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:gravity="center_horizontal|center_vertical"        android:orientation="vertical" >        <ImageView            android:id="@+id/icon"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:paddingTop="3dp"/>        <TextView            android:id="@+id/name"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:paddingTop="5dp"/>    </LinearLayout></LinearLayout>

主布局通用

<?xml version="1.0" encoding="utf-8"?><TabHost xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@android:id/tabhost"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    >    <LinearLayout        android:orientation="vertical"        android:layout_width="fill_parent"        android:layout_height="fill_parent">        <FrameLayout            android:id="@android:id/tabcontent"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:layout_weight="1">        </FrameLayout>        <TabWidget            android:id="@android:id/tabs"            android:layout_width="fill_parent"            android:layout_height="100dp"            android:layout_weight="1"            android:background="@color/tab_bottom_bar"            />    </LinearLayout></TabHost>
