TabHost三种方法

方式一：TabHost继承TabActivity方法相当简单

首先看布局文件activity_main.xml

<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent" >    <!-- 第一个布局 -->    <LinearLayout        android:id="@+id/view1"        android:layout_width="match_parent"        android:layout_height="match_parent" >        <TextView            android:id="@+id/textView1"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="Tab1" />    </LinearLayout>    <!-- 第二个布局 -->    <LinearLayout        android:id="@+id/view2"        android:layout_width="match_parent"        android:layout_height="match_parent" >        <TextView            android:id="@+id/textView2"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="Tab2" />    </LinearLayout>    <!-- 第三个布局 -->    <LinearLayout        android:id="@+id/view3"        android:layout_width="match_parent"        android:layout_height="match_parent" >        <TextView            android:id="@+id/textView3"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="Tab3" />    </LinearLayout></FrameLayout>

然后就是一个activity就行了MainActivity

package com.example.tabhost_trynew;import com.example.tabhost_trynew.R;import android.app.TabActivity;import android.os.Bundle;import android.view.LayoutInflater;import android.view.Menu;import android.widget.FrameLayout;import android.widget.TabHost;import android.widget.TabHost.OnTabChangeListener; import android.widget.TabHost.TabSpec;public class MainActivity extends TabActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);//TabHost extends FrameLayoutTabHost tabHost = getTabHost();////把我们的布局文件添加到tabHost的FrameLayout下面 LayoutInflater.from(this).inflate(R.layout.activity_main,tabHost.getTabContentView(), true);/** * public void addTab(TabSpec tabSpec) * tabSpec:A tab has a tab indicator, content, and a tag  *  */tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("tab1", getResources().getDrawable(R.drawable.ic_launcher)).setContent(R.id.view1));tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("tab2").setContent(R.id.view2));tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("tab3").setContent(R.id.view3)); //setOnTabChangedListener        tabHost.setOnTabChangedListener(new OnTabChangeListener(){              @Override            public void onTabChanged(String tabId) {            if (tabId.equals("tab1")) {                   }                if (tabId.equals("tab2")) {                   }                if (tabId.equals("tab3")) {                  }            }                    });             }}

方式二：TabHost继承Activity(xml布局实现)

activity_main.xml

<LinearLayout 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"     android:orientation="vertical"    tools:context=".MainActivity" >    <!-- TabHost是盛放Tab的容器。TabHost必须包含一个 TabWidget和一个FrameLayout -->     <TabHost        android:id="@+id/tabhost"        android:layout_width="match_parent"        android:layout_height="match_parent">         <!-- 这里添加一个布局，原因是 -->        <LinearLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical" >            <!-- TabWidget用来显示选项卡 -->            <TabWidget                android:id="@android:id/tabs"                android:layout_width="match_parent"                android:layout_height="wrap_content" >            </TabWidget>            <!-- 用来显示选项卡对应的内容 -->            <FrameLayout                android:id="@android:id/tabcontent"                android:layout_width="match_parent"                android:layout_height="match_parent" >                <!-- 第一个tab的布局 -->                <LinearLayout                    android:id="@+id/tab1"                    android:layout_width="match_parent"                    android:layout_height="match_parent" >                    <TextView                        android:id="@+id/textView1"                        android:layout_width="match_parent"                        android:layout_height="match_parent"                        android:text="林炳东" />                </LinearLayout>                <!-- 第二个tab的布局 -->                <LinearLayout                    android:id="@+id/tab2"                    android:layout_width="match_parent"                    android:layout_height="match_parent" >                    <TextView                        android:id="@+id/textView2"                        android:layout_width="match_parent"                        android:layout_height="match_parent"                        android:text="张小媛" />                </LinearLayout>                <!-- 第三个tab的布局 -->                <LinearLayout                    android:id="@+id/tab3"                    android:layout_width="match_parent"                    android:layout_height="match_parent" >                    <TextView                        android:id="@+id/textView3"                        android:layout_width="match_parent"                        android:layout_height="match_parent"                        android:text="马贝贝" />                </LinearLayout>            </FrameLayout>        </LinearLayout>    </TabHost>     </LinearLayout>

MainActivity

package com.example.tabhost_try2;import android.os.Bundle;import android.app.Activity;import android.view.Menu;import android.widget.TabHost;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);TabHost th=(TabHost)findViewById(R.id.tabhost);// 作用是来初始化我们的TabHost容器：th.setup();            th.addTab(th.newTabSpec("tab1").setIndicator("tab1",getResources().getDrawable(R.drawable.ic_launcher)).setContent(R.id.tab1));th.addTab(th.newTabSpec("tab2").setIndicator("tab2",null).setContent(R.id.tab2));th.addTab(th.newTabSpec("tab3").setIndicator("tab3",null).setContent(R.id.tab3));}}

拆分方法（跟方法二类似）

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <TabHost        android:id="@+id/tabhost"                 android:layout_width="match_parent"        android:layout_height="match_parent" >        <LinearLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical" >            <TabWidget                android:id="@android:id/tabs"                android:layout_width="match_parent"                android:layout_height="wrap_content" >            </TabWidget>            <FrameLayout                android:id="@android:id/tabcontent"                android:layout_width="match_parent"                android:layout_height="match_parent" >                            </FrameLayout>        </LinearLayout>    </TabHost></LinearLayout>

tab1.xml

<?xml version="1.0" encoding="UTF-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"       android:id="@+id/LinearLayout01"        android:layout_width="wrap_content"       android:layout_height="wrap_content">       <TextView             android:text="我是标签1的内容喔"            android:id="@+id/TextView01"             android:layout_width="wrap_content"            android:layout_height="wrap_content">       </TextView> </LinearLayout>

tab2.xml

<?xml version="1.0" encoding="UTF-8"?><LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"        android:id="@+id/LinearLayout02"        android:layout_width="wrap_content"        android:layout_height="wrap_content">        <TextView android:text="标签2"                  android:id="@+id/TextView01"                   android:layout_width="wrap_content"                  android:layout_height="wrap_content" /></LinearLayout>

MainActivity

package com.example.tabhost_try3;import android.os.Bundle;import android.app.Activity;import android.view.LayoutInflater;import android.view.Menu;import android.widget.TabHost;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);TabHost m = (TabHost) findViewById(R.id.tabhost);m.setup();LayoutInflater i = LayoutInflater.from(this);i.inflate(R.layout.tab1, m.getTabContentView());i.inflate(R.layout.tab2, m.getTabContentView());m.addTab(m.newTabSpec("tab1").setIndicator("tab1").setContent(R.id.LinearLayout01));m.addTab(m.newTabSpec("tab2").setIndicator("tab2").setContent(R.id.LinearLayout02));}}
