1.通过继承Activity实现

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>        <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"      android:id="@+id/hometabs"      android:orientation="vertical"      android:layout_width="fill_parent"        android:layout_height="fill_parent">           <TabHost android:id="@+id/tabhost"          android:layout_width="fill_parent"          android:layout_height="wrap_content"        android:layout_alignParentLeft="true"          android:layout_alignParentBottom="true" >                  <LinearLayout              android:orientation="vertical"              android:layout_width="fill_parent"              android:layout_height="fill_parent">                           <FrameLayout android:id="@android:id/tabcontent"                    android:layout_width="fill_parent"                    android:layout_height="wrap_content">                      <TextView android:id="@+id/view1"                          android:layout_width="fill_parent"                          android:layout_height="fill_parent"/>                      <TextView android:id="@+id/view2"                          android:layout_width="fill_parent"                          android:layout_height="fill_parent"/>                      <TextView android:id="@+id/view3"                          android:layout_width="fill_parent"                          android:layout_height="fill_parent"/>               </FrameLayout>                                        <TabWidget android:id="@android:id/tabs"                 android:orientation="horizontal"                android:layout_width="fill_parent"                android:layout_height="wrap_content"              android:layout_gravity="bottom">              </TabWidget>          </LinearLayout>      </TabHost>  </RelativeLayout>

MainActivity.java

package com.example.testtabhost;import android.R.integer;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.widget.TabHost;import android.widget.TabHost.OnTabChangeListener;import android.widget.Toast;  public class MainActivity extends Activity {       protected void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.activity_main);                    TabHost tabHost = (TabHost) findViewById(R.id.tabhost);          tabHost.setup();                        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("4").setContent(R.id.view1));                    tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("5").setContent(R.id.view3));                    tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("6").setContent(R.id.view2));           tabHost.setCurrentTab(1);                tabHost.setOnTabChangedListener(new OnTabChangeListener() {@Overridepublic void onTabChanged(String tabId) {// TODO Auto-generated method stub  if (tabId.equals("tab1")) {    // Intent intent =new Intent(); // intent.setClass(MainActivity.this, OtherActivity.class);  Toast.makeText(getApplicationContext(), "1", Toast.LENGTH_SHORT).show();  }  if (tabId.equals("tab2")) {  Toast.makeText(getApplicationContext(), "2", Toast.LENGTH_SHORT).show();        }          if (tabId.equals("tab3")) {          Toast.makeText(getApplicationContext(), "3", Toast.LENGTH_SHORT).show();         }}}) ;      }    }

2.待续

继承TabActivity实现

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"      xmlns:tools="http://schemas.android.com/tools"      android:layout_width="match_parent"      android:layout_height="match_parent" >        <ImageView           android:id="@+id/tab2"          android:layout_width="fill_parent"          android:layout_height="fill_parent"          android:src="@drawable/image2"/>      <ImageView          android:id="@+id/tab3"          android:layout_width="fill_parent"          android:layout_height="fill_parent"          android:src="@drawable/image3"/>    </RelativeLayout>

tab1_item.xml

<?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:orientation="horizontal" >        <ImageView          android:id="@+id/image"          android:padding="10dp"          android:layout_width="48dp"          android:layout_height="48dp" />        <LinearLayout          android:layout_width="fill_parent"          android:layout_height="wrap_content"          android:orientation="vertical" >            <LinearLayout              android:layout_width="fill_parent"              android:layout_height="wrap_content"              android:orientation="horizontal" >                <TextView                  android:id="@+id/name"                  android:paddingTop="10dp"                  android:layout_width="wrap_content"                  android:layout_height="wrap_content" />                <TextView                  android:id="@+id/publish"                  android:layout_width="fill_parent"                  android:layout_height="wrap_content"                  android:paddingTop="10dp"                  android:gravity="right" />          </LinearLayout>            <TextView              android:id="@+id/content"              android:paddingTop="10dp"              android:paddingBottom="10dp"              android:layout_width="fill_parent"              android:layout_height="wrap_content" />      </LinearLayout>    </LinearLayout>
