It seems google may have shipped android with a tab widget that is said to be deprecated from the time of release.
Here is a simple method I’ve used to implement tab-like functionality that seems to work well for me. You can easily change the background of the buttons to look just like tabs, but I kept the example as clean and simple as possible.

Here’s a little snippet I wrote to access resources in R.java during runtime. It just uses reflection to get the filed names of the objects in the R class.
ameya is discussing.
public class RR {
public static Drawable getDrawable(Context context, String name) {
Class c = R.drawable.class;
Drawable d = null;
Field f;
int i = 0;
try {
f = c.getField(name);
i = f.getInt(f);
d = context.getResources().getDrawable(i);
} catch (Exception e) {
Log.e("RR",e.toString());
}
return d;
}
public static String getString(Context context, String name) {
Class c = R.string.class;
String s = null;
Field f;
int i = 0;
try {
f = c.getField(name);
i = f.getInt(f);
s = context.getResources().getString(i);
} catch (Exception e) {
Log.e("RR",e.toString());
}
return s;
}
}
With this class you could access resources at run time just like the example below. I found this extremely useful in one scenario where I switch Drawable resources out at run-time based on user interaction.
// inside any view/action Drawable icon = RR.getDrawable(this,"myicon"); String mystring = RR.getString(this,"icon_name");
Feel free to use the code above in your projects. I would really like to see your hacks and improvements for it.
See Resources.getIdentifier. For example: http://www.anddev.org/viewtopic.php?p=17846
Ah, absolutely. This post is _very_ dated and I not recommend using my code example to anyone.
but with the example http://www.anddev.org/viewtopic.php?p=17846, we can’t get a button id for example. Steven, it could be possible with your code example, but is it recommendable? please, help me with this little trouble. (you can send me a mail)
This code is really dated, I know there is a much cleaner way to do this now, but unfortunately I haven’t kept up with my Android development and can’t be to much help.
Carlos,
You want this:
Log.i(TAG, “Found Button ID: ” + getResources().getIdentifier(“Button01″, “id”, “com.android.test”));
or
Log.i(TAG, “Found Button ID: ” + getResources().getIdentifier(“com.android.test:id/Button01″));
The code mentioned shows how to get a drawable, just replace drawable for another type in the resource file (id, drawable, layout, string, etc)
thanx, thats what I needed 
I noticed this interesting entry in my server’s access log today. I certainly have phpMyAdmin running at that location, but you can’t get the process list unless you login.
66.249.70.89 xxxxxxxxx.com – [21/Nov/2007:13:43:18 -0800] “GET /MyAdmin/server_processlist.php?lang=en-utf-8&convcharset=iso-8859-1&collation_connection=utf8_unicode_ci&token=a1bb5490499a10bb493edc160625e33b&kill=49481 HTTP/1.1″ 404 345 “-” “Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)”
You can do two things at that screen:
Neither of witch is something I would expect Google to be interested in on my personal webserver.
I’ve had a lot of fun hacking on Android applications recently and I’m really looking forward to seeing the future of Android unfold. My first project was the the password safe I mentioned in my last post and while working on some features for it I was looking for an example of a composite view that allowed you have cute little icons next to each entry in a list, I found a few examples that did similar things, but nothing was quite what I was looking for so I threw together the view you see here last night. I’m sure someone is else is looking to do something similar so I thought I would post about it and make it available to everyone.
Most of the magic happens by in the BulletedText View class. I basically just extend LinearLayout and create a composite view that contains an ImageView and TextView object: (Sorry if the code is a little cramped, I need to figure out how to keep wordpress from eating blank lines)
keckia, 
Tim H, 
public class BulletedTextView extends LinearLayout {
private TextView mText;
private ImageView mBullet;
public BulletedTextView(Context context, String text, Drawable bullet) {
super(context);
this.setOrientation(HORIZONTAL);
mBullet = new ImageView(context);
mBullet.setImageDrawable(bullet);
// left, top, right, bottom
mBullet.setPadding(0, 2, 5, 0);
addView(mBullet, new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
mText = new TextView(context);
mText.setText(text);
addView(mText, new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
public void setText(String words) {
mText.setText(words);
}
public void setBullet(Drawable bullet) {
mBullet.setImageDrawable(bullet);
}
}
Then I created a custom list adapter for my view.
(More …)
any changes coming ?
VataMyday, I’m afraid not. I haven’t had much interest lately in Android development and haven’t put much thought into it.
I’ve got my first working Android application together. It’s just a simple password safe with some decent features for a first release including:
Here are a couple of screen shots to give you an idea of what the application looks like (Click to enlarge)
Plans for future versions include:
You can always download it and check it out for yourself. Let me know what you think and if you find any bugs or have ideas for improvements.
Hi Steve. Great application. Maybe in the future can sync with another desktop application (1 password or keepassx). Congratulations.
Hi Steve,
I was thinking about upgrading to an Android phone but couldn’t find a password app in the store so this is great.
One enhancement I would love would be to able to sync with a desktop app so secrets could be edited and accessed from both my phone and desktop.
Thanks again.
Hi Steve I would also like an application that can sync with a desktop application as well, also a search function would be good as this is used a lot in my existing password store.
@Graeme this project is now part of OpenIntents and is not maintained by me. Check out http://www.openintents.org/en/node/205 I recommend filing a feature request with them.
I got an invitation to take the Paypal Anti-Phishing challenge. It’s all of 5 questions long, but it’s a neat way to educate user’s about phising.
I have the privilege of attending this years Internet Identity Workshop in Mountain View. I’ll be hanging out there Dec 3-5. I’ll try to get some pics and things to post on my blog along with an overview of the event.
Graeme, 
Mark and 2 others are discussing.
