Android TabHost的使用(Tab为Layout)

Android TabHost的使用，这里采用继承TabActivity的方法。

这里分别定制三个Tab，分别为american.xml, chinese.xml, japanese.xml三个Layout。

american.xml文件

<?xml version= "1.0"  encoding= "utf-8" ?> <LinearLayout xmlns:android= "http://schemas.android.com/apk/res/android"      android:layout_width= "match_parent"      android:layout_height= "match_parent"      android:orientation= "vertical"  >        <Button          android:id= "@+id/button1"          android:layout_width= "wrap_content"          android:layout_height= "wrap_content"          android:text= "American1"  />        <Button          android:id= "@+id/button2"          android:layout_width= "wrap_content"          android:layout_height= "wrap_content"          android:text= "American2"  />   </LinearLayout>

　chinese.xml文件

<?xml version= "1.0"  encoding= "utf-8" ?> <LinearLayout xmlns:android= "http://schemas.android.com/apk/res/android"      android:layout_width= "match_parent"      android:layout_height= "match_parent"      android:orientation= "vertical"  >          <Button          android:id= "@+id/button1"          android:layout_width= "wrap_content"          android:layout_height= "wrap_content"          android:text= "Chinese button 1"  />        <Button          android:id= "@+id/button2"          android:layout_width= "wrap_content"          android:layout_height= "wrap_content"          android:text= "Chinese button 2"  />   </LinearLayout>

　　japanese.xml文件

<?xml version= "1.0"  encoding= "utf-8" ?> <LinearLayout xmlns:android= "http://schemas.android.com/apk/res/android"      android:layout_width= "match_parent"      android:layout_height= "match_parent"      android:orientation= "vertical"  >                <Button          android:id= "@+id/button1"          android:layout_width= "wrap_content"          android:layout_height= "wrap_content"          android:text= "Japanese button 1"  />            <Button              android:id= "@+id/button2"              android:layout_width= "wrap_content"              android:layout_height= "wrap_content"              android:text= "Japanese button 2"  />   </LinearLayout>

 

三个Layout对应的java文件为AmericanActivity.java, ChinaActivity.java, JapanActivity.java

AmericanActivity.java文件

public  class  AmericanActivity extends Activity {         @Override          protected  void  onCreate(Bundle savedInstanceState) {              super.onCreate(savedInstanceState);              setContentView(R.layout.american);                     } }

　　ChinaActivity.java文件

public  class  ChinaActivity extends Activity {         @Override          protected  void  onCreate(Bundle savedInstanceState) {              super.onCreate(savedInstanceState);              setContentView(R.layout.chinese);                       } }

　　JapanActivity.java文件

public  class  JapanActivity extends Activity {         @Override          protected  void  onCreate(Bundle savedInstanceState) {              super.onCreate(savedInstanceState);              setContentView(R.layout.japanese);                      } }

　　

MainActivity.java 继承TabActivity。

public  class  MainActivity extends TabActivity {        @Override      protected  void  onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          //setContentView(R.layout.activity_main);          Resources resources = getResources();          TabHost tabHost = getTabHost();                    TabHost.TabSpec spec;                    Intent intent = new  Intent( this ,AmericanActivity. class  );          spec = tabHost.newTabSpec( "American" );          spec.setIndicator( "Ameican Tab" );          spec.setContent(intent);          tabHost.addTab(spec);                    Intent intent2 = new  Intent( this ,ChinaActivity. class  );          spec = tabHost.newTabSpec( "China" );          spec.setIndicator( "China Tab" )          spec.setContent(intent2);          tabHost.addTab(spec);                    Intent intent3 = new  Intent( this ,JapanActivity. class  );          spec = tabHost.newTabSpec( "Japanese" );          spec.setIndicator( "Japanese Tab" );          spec.setContent(intent3);          tabHost.addTab(spec);                    tabHost.setCurrentTab(1);      }         }

　　注意：在AndroidManifest文件中加入下面三行代码。

<activity android:name= "com.example.app1.AmericanActivity"  android:label= "@string/app_name" ></activity> <activity android:name= "com.example.app1.JapanActivity"  android:label= "@string/app_name" ></activity> <activity android:name= "com.example.app1.ChinaActivity"  android:label= "@string/app_name" ></activity>
