Use of Android tahhost

Android tahhost is used. The tabactivity inheritance method is used here.

Here, three tabs are customized: American. XML, Chinese. XML, and Japanese. xml.

American. xml file

<?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 file

<?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>

　　Japan. xml file

<?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>

 

The java files corresponding to the three layout are americanactivity. Java, chinaactivity. Java, and Japan activity. java.

Americanactivity. Java File

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

　Chinaactivity. Java File

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

　　Japanactivity. Java File

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

　　

Mainactivity. JavaInherit 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);    }    }

Note: Add the following three lines of code to the androidmanifest file.

        <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>
