TabHost的简单实用

TabHost已经过时了的一个控件，如今维护以前的项目，自己重新复习下：

（1）       设置布局：添加一个FragmentLayout作为内容的显示容器，添加TabWidget,作为选项卡控件

（2）       Activity继承TabActivity

（3）       TabSpc设置选项卡的内容，每个选项卡对应的内容，每个选项卡的标识。

 

 

TabSpec page1 = tabhost.newTabSpec("one")//标识

                .setIndicator("叫兽")//选项卡内容

                .setContent(R.id.isanimal);//显示内容：可以设置View,和Intent,还有TabHost.TabContentFactory

tabhost.addTab(page1);//添加选项卡和内容。

 

布局：需要注意布局中的id

<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="com.example.mytabhost.MainActivity">

 

   <TabHost

        android:id="@android: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">

 

            <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="match_parent"

               android:layout_height="wrap_content"

               android:layout_weight="0"

                android:background="#ff00ff00">

            </TabWidget>

        </LinearLayout>

   </TabHost>

 

</LinearLayout>

Activity:

@SuppressWarnings("deprecation")

public class MainActivity extendsTabActivity {

         TabHosttabhost;

         FrameLayouttab_content;

         IntentjiaoShouIntent,laoShiIntent,neZhaIntent;

   @Override

   protected void onCreate(Bundle savedInstanceState) {

       super.onCreate(savedInstanceState);

       this.requestWindowFeature(Window.FEATURE_NO_TITLE);

       setContentView(R.layout.activity_main);

       tabhost=getTabHost();

       //tab_content=(FrameLayout) findViewById(R.id.tab_content);

       jiaoShouIntent=new Intent(this, JiaoShouActivity.class);

       laoShiIntent=new Intent(this, LaoShiActivity.class);

       neZhaIntent=new Intent(this, NeZhaActivity.class);

       setTab();

    }

   public void setTab(){

             TabSpec page1 =tabhost.newTabSpec("one")

                .setIndicator("叫兽")

                .setContent(jiaoShouIntent);

             tabhost.addTab(page1);//添加选项卡和内容。

        

        TabSpec page2 =tabhost.newTabSpec("two")

                .setIndicator("老湿")

                .setContent(laoShiIntent);

        tabhost.addTab(page2);

        

        TabSpec page3 =tabhost.newTabSpec("three")

                .setIndicator("哪吒")

                .setContent(neZhaIntent);

        tabhost.addTab(page3);

    }

}

 

与RadioGroup联合使用：

布局：只是添加了一个RadioGroup

<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="com.example.mytabhost.MainActivity">

 

   <TabHost

        android:id="@android: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">

 

            <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="match_parent"

               android:layout_height="wrap_content"

               android:layout_weight="0">

 

                <RadioGroup

                    android:layout_width="match_parent"

                    android:layout_height="wrap_content"

                    android:layout_weight="0"

                    android:orientation="horizontal">

 

                    <RadioButton

                        android:id="@+id/jiaoshou"

                        style="@style/main_tab_bottom"

                        android:drawableTop="@drawable/tabs_home"

                        android:text="教授" />

 

                    <RadioButton

                        android:id="@+id/laoshi"

                        style="@style/main_tab_bottom"

                        android:drawableTop="@drawable/tabs_sort"

                        android:text="老湿" />

 

                    <RadioButton

                        android:id="@+id/nezha"

                        style="@style/main_tab_bottom"

                      android:drawableTop="@drawable/tabs_search"

                        android:text="哪吒" />

                </RadioGroup>

            </TabWidget>

        </LinearLayout>

   </TabHost>

 

</LinearLayout>

Activity：只是对RadioGroup中的Radiobutton设置监听，并设置选定的是某个Tabhost

@SuppressWarnings("deprecation")

public classMainActivity extends TabActivity implements OnCheckedChangeListener {

   TabHosttabhost;

   FrameLayouttab_content;

   IntentjiaoShouIntent,laoShiIntent,neZhaIntent;

   RadioButtonjiaoshou,laoshi,nezha;

   @Override

   protectedvoidonCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        this.requestWindowFeature(Window.FEATURE_NO_TITLE);

        setContentView(R.layout.activity_main);

        jiaoshou=(RadioButton) findViewById(R.id.jiaoshou);

        laoshi=(RadioButton) findViewById(R.id.laoshi);

        nezha=(RadioButton) findViewById(R.id.nezha);

        jiaoshou.setOnCheckedChangeListener(this);

        laoshi.setOnCheckedChangeListener(this);

        nezha.setOnCheckedChangeListener(this);

        tabhost=getTabHost();

        //tab_content=(FrameLayout) findViewById(R.id.tab_content);

        jiaoShouIntent=new Intent(this, JiaoShouActivity.class);

        laoShiIntent=new Intent(this, LaoShiActivity.class);

        neZhaIntent=new Intent(this, NeZhaActivity.class);

        setTab();

   }

   publicvoidsetTab(){

     TabSpec page1 = tabhost.newTabSpec("one")

                .setIndicator("叫兽")

                .setContent(jiaoShouIntent);

     tabhost.addTab(page1);//添加选项卡和内容。

        

        TabSpec page2 = tabhost.newTabSpec("two")

                .setIndicator("老湿")

                .setContent(laoShiIntent);

        tabhost.addTab(page2);

        

        TabSpec page3 = tabhost.newTabSpec("three")

                .setIndicator("哪吒")

                .setContent(neZhaIntent);

        tabhost.addTab(page3);

   }

   @Override

   public voidonCheckedChanged(CompoundButton buttonView, boolean isChecked) {

      switch(buttonView.getId()){

      case R.id.jiaoshou:

        tabhost.setCurrentTabByTag("one");

        break;

      case R.id.laoshi:

        tabhost.setCurrentTabByTag("two");

        break;

      case R.id.nezha:

        tabhost.setCurrentTabByTag("three");

        break;

      }

   }

}
