Question

I have looked at posts on Stack Overflow and at tutorials on other websites, and I cannot understand how to use TabHost. Can someone please explain it to me and maybe send me a link to a tutorial?

1. In ManiActivity extends TabActivity

   public class MainActivity extends TabActivity {
   
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
   
       //setContentView(R.layout.activity_main);
   
       TabHost mTabHost = getTabHost();
   
       mTabHost.addTab(mTabHost.newTabSpec("first").setIndicator("First").setContent(new Intent(this  ,FirstActivity.class )));
       mTabHost.addTab(mTabHost.newTabSpec("second").setIndicator("Second").setContent(new Intent(this , SecondActivity.class )));
       mTabHost.setCurrentTab(0);
   
   
   }
   }
   

• In this activity not use layout “activity_main.xml” .

• Tabhost mTabHost = getTabHost(); is create main tab.

• mTabHost.newTabSpec(“first”) is create tabspec id “first”.

• setIndicator(“First”) is create text “First” in title tab.

• setContent(new Intent(this ,FirstActivity.class )) is use content from FirstActivity.class ( FirstActivity.java )

• mTabHost.addTab(….) is add spectab to main tab

• mTabHost.setCurrentTab(0) is defult tab when start page.

FirstActivity.java

public class FirstActivity extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView( R.layout.first_layout );
}

}

SecondActivity.java

public class SecondActivity extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView( R.layout.second_layout );
}
}

• “R.layout.first_layout” is content from first_layout.xml

• “R.layout.second_layout” is content from second_layout.xml

In AndroidManifest.xml add activity name “.FirstActivity” and “.SecondActivity” in example xml.

Finish!!!!!
