HelloTabWidget on Android

HelloTabWidget on Android (Working)

I saw a few people discussing about their solution of Android HelloTabWidget exercise not working, therefore I publish my solution, I hope it will help you to resolve your problems. The « solution » will not be described, but you can ask your questions and I will try to answer them.

Note :

1) My Project is called HelloTabWidget2

2) My package is called com.tabwidget

Class: HelloTabWidget2Activity

package com.tabwidget;

import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TabHost;

public class HelloTabWidget2Activity extends TabActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Resources res = getResources(); // Resource object to get Drawables
        TabHost tabHost = getTabHost();  // The activity TabHost
        TabHost.TabSpec spec;  // Resusable TabSpec for each tab
        Intent intent;  // Reusable Intent for each tab

        // Create an Intent to launch an Activity for the tab (to be reused)
        intent = new Intent().setClass(this, ArtistsActivity.class);

        // Initialize a TabSpec for each tab and add it to the TabHost
        spec = tabHost.newTabSpec("artists").setIndicator("Artists",
                          res.getDrawable(R.drawable.ic_tab_artists))
                      .setContent(intent);
        tabHost.addTab(spec);

        // Do the same for the other tabs
        intent = new Intent().setClass(this, AlbumsActivity.class);
        spec = tabHost.newTabSpec("albums").setIndicator("Albums",
                          res.getDrawable(R.drawable.ic_tab_albums))
                      .setContent(intent);
        tabHost.addTab(spec);

        intent = new Intent().setClass(this, SongsActivity.class);
        spec = tabHost.newTabSpec("songs").setIndicator("Songs",
                          res.getDrawable(R.drawable.ic_tab_songs))
                      .setContent(intent);
        tabHost.addTab(spec);

        tabHost.setCurrentTab(2);
    }
}

Class: AlbumsActivity

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class AlbumsActivity extends Activity {
	 public void onCreate(Bundle savedInstanceState) {
	        super.onCreate(savedInstanceState);

	        TextView textview = new TextView(this);
	        textview.setText("This is the XX  tab");
	        setContentView(textview);
	    }

}

Class: ArtistsActivity

package com.tabwidget;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class ArtistsActivity extends Activity {
	 public void onCreate(Bundle savedInstanceState) {
	        super.onCreate(savedInstanceState);

	        TextView textview = new TextView(this);
	        textview.setText("This is the Contact Tab");
	        setContentView(textview);
	    }

}

Class:

package com.tabwidget;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class SongsActivity extends Activity {
	 public void onCreate(Bundle savedInstanceState) {

		 super.onCreate(savedInstanceState);

	        TextView textview = new TextView(this);
	        textview.setText("This is the Artists tab");
	        setContentView(textview);
	    }

}
