Android TahHost的使用

Android TahHost的使用，這裡採用繼承TabActivity的方法。

這裡分別定製三個Tab，分別為american.xml, chinese.xml, japanese.xml三個Layout。

american.xml檔案

<?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檔案

<?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檔案

<?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>

 

三個Layout對應的java檔案為AmericanActivity.java, ChinaActivity.java, JapanActivity.java

AmericanActivity.java檔案

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

　　ChinaActivity.java檔案

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

　　JapanActivity.java檔案

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

　　

MainActivity.java 繼承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檔案中加入下面三行代碼。

        <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>
