I have successfully created a custom key pad in my application but i am unable to find out how to display a dictionary of words like android default keypad which appear at the top whenever we type.
1st you need to take an AutoComplete TextView
Afterwards , you need to follow this example:
Creating a Search Interface
In this example the ListView's Data-Source is being changed when the text is entered in Search Bar.You need to change the Data-Source of AutoComplete TextView as the user enters different texts.
I hope this will solve your problem.

I want to implement contacts search like we have in the build in SMS messages app, when you have a text box to enter the contact name and for each letter you insert , a scrollable list of contacts which thier name starts with the input text is displayed on screen, right under the text box. If you delete all input or can't find sutable contact then the list disappear.
When the user selects one of the list items then its full name is written in the text box.
What controls should I use to implement this behaviour? Would EditText and a regular ListView will do?
I couldn't find examples...
Please help, thanks
You can use addTextChangeListener in your EditText and search value from your listview.

my problem is creating EditText for phone numbers on Android.

How can I do this?
You need to use AutoCompleteTextView in your layout and then have a look at
http://developer.android.com/reference/android/widget/AutoCompleteTextView.html
and then
http://developer.android.com/training/contacts-provider/retrieve-names.html
In Graphic Layout, rightclick on edittext, in InputType menu, select any number type - number, phonetic
When you will run the app, the on screen keyboard will show only numbers
Its possible to supply phone numbers or contact names as adapter to auto complete text view.
The below link provides you a tutorial to achieve this requirement.
Fetch Phone contacts and Show it in AutoComplete TextView in Android
I am currently working on android project, I want to allow the user to hide or show their password on the screen by selecting a checkbox.
How would I go about replacing every character in the string with * character or is there a particular way to do this.
For example if the password is my_password I want it to be replaced with ***********.
You can use setTransformationMethod on TextView along with PasswordTransformationMethod to display stars.
I have related input text fields in my android application.
The user first enters a parent value (using autocomplete text)
for the related child text entry i have tried a spinner and autocomplete text.
the spinner shows existing values, which is a good start, however i need the user to be able to enter new values as well. Once the user adds a new value this will be incorporated in the drop down list on subsequent views of the screen.
the user may not know all available values so autocomplete doesnt satisfy my requirements as you have to know what is already in the list for it to assist you.
i feel spinner is the best starting point for my child text entry field.
How do i enable text entry into a spinner?
whats the "Best" solution for this problem?
Is it Possible to Display some text say a story, in an ANDROID app which also enables the user to select some text and perform some operations on that text..
the main idea is to display some text and when the user selects some text(a word or a sentence) i need to get that text for some further operation on that text.
we cant use text view as you cant select text in textview,and we cant use editview because the user should not be able to edit the contents of the text.
Why not display the text in a WebView and enable text selection?
It works pretty well in CodePad, which is open source so you can have a look at the code here.
My first try would be to display this text in a normal TextView. Then I would provide two or three buttons to implement the selection of a part of the text. For example 1 Button to start and end selection and 2 Buttons with arrows for increasing/decreasing the part of the selection.
To highlight the part of the text which is selected, I would for example color this part of the text in a different color.
Coloring of text can be either done by using Spannable or the HTML class.
