Dynamically add editextext to android app and retrieve values

I am building an app where the users can add editText dynamically so that I can send those values into my database. Almost all websites I have come across only add views but they don't retrieve the values.

While add view in you set tag edittext useing below method
LinearLayout linLayout = (LinearLayout)findViewWithTag("layout1");
Also for getting text from the edittext you can use below code
EditText etText = (LinearLayout)findViewWithTag(“Tag1”);
String text=etText.getText().ToString();

Finding Id when using array for EditText

I would like to create an array of EditText for android but it seems that finding the id has been a very challenging task.Can someone reach out?
My code for the array:
EdiTText[] mEditText = new EditText[20];
for(int i =0;i<mEditText.length;i++){
mEditText[i] = (EditText) findViewById(i);
}

You cannot set id to view in runtime. Read more about android id here.
Just use constructor to initialize EditText:
mEditText[i] = new EditText(this);

There's two approaches to UI elements like EditText:
a. Implement them in your layout xml like this:
<EditText android:id="#+id/myedittext"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
Here the EditText would have the id "myedittext". You can then do stuff with that EditText by referencing it from your code with
EditText et = (EditText)findViewById(R.id.myedittext);
b. Programmatically create them like
EditText et = new EditText(context)
With this approach you will also have to manually add this EditText to your UI / layout.
You mixed those two approaches in a way that won't work.
If you don't know beforehand how many UI elements (in your case EditTexts) you need, it's cool to create them programmatically, but you should definitely read up on how to do that properly.

I'm not going to ask why you're trying to do this. However...
The resource IDs needed by findViewById will not start at zero as implied by your code snippet which uses the loop index for id.
If the EditText are created in XML, then you need the resource IDs of the form R.id.xxxx. You could create an int[] of the IDs and pass the corresponding id to findViewById.
If you create the EditText in code, then you won't have IDs, so will have to store the EditText objects at creation time.

How to auto fill an edit text in android application?

I am developing one android application. In which I have some Products and form to purchase that product. In the Order form I have one Edit Text as Product ( means product name) .
In my application user has to type Product name but I want to know that Is there any way that
the EditText field is autofilled with that particular Product like as in flipcart.
Any one knows then suggest me...
Thanks in advance...

When you want to populate it just call (after reading it in from the XML layout in this example):
EditText myTextBox = (EditText) findViewById(R.id.editBox);
myTextBox.setText("My Product Description");
If what you are looking for is an auto completion after they have started typing, then an AutoCompleteTextView is your best bet, replacing the EditText and providing the auto complete functionality
There is an example of this over at the Android Developers website:
http://developer.android.com/guide/topics/ui/controls/text.html#AutoComplete

you can use autocomplete textview for suggestion of your all the product names, refer this example http://saigeethamn.blogspot.in/2010/05/auto-complete-text-view-android.html
or you just want to show when app launches, use hint
android:hint="#string/enterproduct"

I Dont get u clearly..
Sooo.
If u want to show text that which user has to fill use Hint.
android:hint="Enter any Filpcart Item"
OR
If u need auto complete text then use above link #kumaand.

Here you can use "input type" in XML design according to the text field.

Add into the XML file
android:autofillHints="emailAddress"
or
android:autofillHints="password"

Dynamic Text Field - Android

I'm trying to create a dynamic text field that will take multiple fields of user input during a single activity, do a calculation in the java file, and then display the resulting value within the SAME activity in a text field.
Is there any way of doing this? I just figured out that I can't edit strings.xml dynamically, so are there any structures I can use that will allow me to constantly change the values?
Thanks all.

This will be pretty straight forward:
String yourTextValue = "text";
TextView myTextView = (TextView) findViewById(R.id.textView1);
myTextView.setText(yourTextValue);
Just call setText() with your String value (whatever it may be) each time you want to change the value of your TextView.

Loading data to TextView in Android

I have a XML tag like "Yes,No,Dontknow " and I am parsing the XML file and getting the data. Now I need to display each option in separate TextView, i.e: 'yes' should be displayed in one TextView, 'No' should be displayed in another TextView, and 'Dontknow' should be displayed in another TextView, but how can I do this, can anyone give me some idea (I am new to Android).

Use setText() method of TextView to load text into it.

You can use string tokenizer:
StringTokenizer tokens = new StringTokenizer(theString, ",");
while( tokens.hasMoreTokens() ){
String token = tokens.nextToken();
// here you must have the reference to the text view...
textView.setText(token);
}
If you are creating the text views programmatically, then you must create or reference those text views inside the loop. Other wise, if the text views are static, you better put each token inside an array or something (words[0] will be Yes, word[1] will be No, etc) and then you set those strings manually.

You can just declare 3 separate TextView in you Activity layout file. Using attribute android:text you can assign the text for the TextView.
Example:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Yes"
/>

parse xml file store that in a string.take an array like String[] array = parsedstring.split(","); then take 3 text views ,put array[0],array[1],array[2] on to textview

If you want to split comma-separated strings, take a look at using java.util.StringTokenizer. You can tell it to use , as the token separator.
