I am just starting with android. This is what i want to make:
Now when you click on From, a new screen would open where you can select places and once you select you will get back to this screen where instead of "Bangalore" it would be the place you selected.
What kind of a field is this ? Text field ?
Also if i want to add any effect like when you click on it its color changes, how would i go about it ? Any tutorials or documentation i can check out for this.
Yes, you will probably want to use TextView.
You can change the text it displays by using SetText(), and you can change the text color by using SetTextColor().
You need a TextView to display text, but if you want to display an image, text and be able to interact with that, then Button or ImageButton is what you need.
Your question is too broad, so I encourage you to start doing some tutorials. To implement all that stuff you'll need to learn about layouts and activities, dialogs, listviews, ... Basic Android, but it needs a minimum of experience.

I want to display a text where certain words lead to other activities within the application.
Is there a more convenient way to achieve it other than having a bunch of TextViews along with buttons (with the clickable words and a transparent background) side by side?
Just the bunch of TextViews and their onClick(s) should do, you wouldn't need the Buttons..
You can take a look at the Linkify class, that searches for some predefined links in the text such as phone numbers, e-mail addresses and web links and automatically makes them clickable and leading to the corresponding activities when clicked. I think there is a possibility of adding your own pattern to recognize words in the text and bind them to activities you want to be used for those words. Hope this helps.
Please check both of the links

i want text to be combined with it as above image.
please help me.

So the simplest thing to do would be to create a Compound Control. This compound control would essentially be a LinearLayout with both and ImageView and a TextView in it. Then, where ever you use a CarouselImageView in your code, just use your new compound control instead.
I am new to android. I was stuck on a problem but I finally solved it.
I was using a TextField instead of CompleteTextViewField so whats the difference between these two and when should I use each one of them?
Thanks
Neither of those classes you mention (TextField, CompleteTextViewField) exist. Do you mean EditText and AutoCompleteTextView? I think the documentation explains it pretty well:
[AutoCompleteTextView is] An editable text view that shows completion suggestions automatically while the user is typing. The list of suggestions is displayed in a drop down menu from which the user can choose an item to replace the content of the edit box with.
That is, use it rather than a normal EditText if you have a set of common autocompletions for what gets entered in the box. The docs also link to a full sample that shows how to populate that list of suggestions with an Adapter.
Pretty new to android so excuse me if this is a really obvious question.
Say my application has a bunch of TextViews, each one showing the attributes of a certain product (name, price, etc). I have a button next to each of these TextViews labeled "modify".
How do I make it so that when I press the modify button next to a certain attribute, a popup window with a space to enter text into comes up so that the user can enter text into this box and then have the actual attribute listing on the original page change? Actually I just need a push in the right direction with creating this popup text field... not sure if there is already some built in functionality for this or if not, what would be the best way to create this kind of thing.
Thanks.
Why not have the modify button set TextEdit.setEnabled(true); and then change focus with TextEdit.setFocus? Note that both of these are inherited from view
If you really want a dialog you might want to looking into the AlertDialog.Builder. I know you can use it with buttons and radio buttons, but I'm not sure you can get it to work with a TextView.
Use a code like this for the input popup: Android dialog input text
In the positive button handler, set your edittext content programmatically like this:
myEditText.setText(value).
As simple as that. The only difference with a standard GUI framework is that you don't retrieve the value as a result of the popup function. Instead, you must provide an action handler.
I have to create a small panel like thing with a border.
This should contain a text, an image that describes the text and a button.
On clicking that button I have to do some operations also.
Which widget is suitable for this?
Can anyone suggests any idea?
ImageButton is what I can think of. Try the ApiDemo sample application comes up with android sdk too. Another tool you might need is DroidDraw (Free android UI designer) and hierarchyviewer.bat(inside android sdk tools) can also help you if you want to know how the other developers use for such purpose.
I have assumed that you want to display button with images + Text,
You can do it with Button. There are 2 ways to do it(Button with Image and Text).
By xml, you can set
android:background attribute of
button and the text which you set,
will be appeared above the
background.
By code, You can use
setBackgroundDrawable() , it is
used to set the background of a
button.
and If you want to display panel(By clicking on the handle of that panel, it will comes up with the many items as home screen) , slidingDrawer widgets is the best solution.
