How to create dynamic xml file in res in android

I want solution of following:
I have create xml file in data/data/com.example.file/files/abc.xml so during running of app how I get this abc.xml in res/layout and should display on screen.
Thanks.

In general, the XML vocabulary for declaring UI elements closely
follows the structure and naming of the classes and methods, where
element names correspond to class names and attribute names correspond
to methods.
Courtesy goes to #Mike M : You cant create this .XML files used for layouts are pre-compiled .

I'm not sure I have followed your question- are you trying to attach a child view to the RelativeLayout? If so you want to do something along the lines of:
RelativeLayout item = (RelativeLayout)findViewById(R.id.item);
View child = getLayoutInflater().inflate(R.layout.child, null);
item.addView(child);
the RelativeLayout item will be the container for your child view.

Your question needs to be a bit more specific, but here's a general answer:
If you are using fragments then you should re-create your fragment and then use:
inflater.inflate(R.layout.abc, container, false);
If you are using activities then you should use:
setOnContentView(abc);

ListView Create cell programmatically

I need to put a series of checkboxes in the cell of a ListView. The problem is that I do not know ahead of time how many. I am guessing, but please correct me if I am wrong, that I need to create it programmatically. There will only be a few cells so I am not worried about reusability. How do I approach doing that?
No xml just build the cell in the getView method --> is this as simple as creating a View and add to it?
xml but append checkboxes to the xml --> I have no idea how to do this.
Is there some sort of dynamic xml CheckBox list that I can use?

I always prefer to use XML to separate the presentation of the controller (or code that controls the app)..
You just need to create a list view and define it's adapter. The adapter will have an XML (a row) where you can design the checkbox and the other elements that you want...
Check out the documentation where you can see an example of a listview with an adapter.
-- edit:
In your case you need to add the checkboxes programmatically in your adapter. Just define a view in your xml where you can add your checkboxes.
-- edit2:
Here is an example XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="50dp" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/checkboxContainer" >
</RelativeLayout>
</RelativeLayout>
In your adapter you
//get the container
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.NAME_OF_YOUR_XML, parent, false);
RelativeLayout your_container = (RelativeLayout) rowView.findViewById(R.id.checkboxContainer);
//declare your checkbox
CheckBox cb = new CheckBox(context);
cb.setText("your text");
// add the checkbox to your container
your_container.addView(cb);
This is just an example. I didn't test the code. Maybe you should use a linear layout instead of a relative layout to place your checkboxes easily..

easiest and most flexible is to use the ArrayAdapter and make an XML layout that looks like the single cell you'd want. Put your data in the array, create the Adapter and assign it to the ListView, and boom, your list has the right number of rows (cells). You can also customize the binding easily so that each cell has some information based on the corresponding Array entry.

Combine multiple xml files into one final android layout

Say I have a layout file that I would like to use as part of another layout, how would I do that?
For example, I have a table layout at /res/layout/table.xml. I want to use that table as a component inside a relative layout at /res/layout/relative_stuff.xml. Say my relative layout is to contain the table and two buttons.
The simple case is to do the combination completely inside the relative_stuff.xml file. But a better case would be the ability to set the table xml programmatically: the reality is I want to choose from many different tables, for now say two tables at: /res/layout/table_1.xml and /res/layout/table_2.xml.
So basically my main layout file is /res/layout/relative_stuff.xml. And I want to set either of two tables inside it programmatically.

You an re-use layouts using an include tag.
For example, using your example layout/table.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width=”match_parent”
android:layout_height=”match_parent”>
<include layout="#layout/table"/>
</LinearLayout>
If you don't want to do it in XML, you can use a LayoutInflater to inflate your XML and add it to whatever container you are using.
LayoutInflater mLayoutInflater = (LayoutInflater) context.getSystemService(LAYOUT_INFLATER_SERVICE);
View tableLayout = mLayoutInflater.inflate(R.layout.table, (ViewGroup) findViewById(R.layout.root_id));
rootLayout.addView(tableLayout);

You can use Layout Inflator Service to add multiple add the activity.

Dynamically add UI content in android

I have an android app which asks a question followed by x number of options.
Each option contains a textview, ImageView and a radio button.
The value of x (i.e. the number of options) is not constant. I want to dynamically add UI content to satisfy this requirement.
At the moment I have written the code in the layout's xml to display a maximum of 4 options. If number of options is 2 I hide the options 3 and 4 using something like
tvoption1.setVisibility(View.GONE);
tvoption2.setVisibility(View.GONE);
However this is not very scalable. Can anyone tell me how to add options for java dynamically. Or is there a better approach?

A View can be added at runtime by using the inflater like this:
LinearLayout linearLayout = (LinearLayout)inflater.inflate(R.layout.news_categories_item, null);
TextView categoryValueTextView = (TextView)linearLayout.findViewById(R.id.news_category_item_value);
mMainLinearLayout.addView(categoryValueTextView);
In this example, a LinearLayout containing a TextView is inflated. A reference to the constituent TextView is then obtained, and the TextView is dynamically added (at runtime) to the main linear layout (mMainLinearLayout).
The inflater object may be obtained in an Activity by using getLayoutInflater().

create your row layout separately, from the main xml
Get LayoutInflater service from context:
LayoutInflater inflater=(LayoutInflater)getSystemService(LAYOUT_INFLATE_SERVICE);
use following method to addview to main xml, I assume you have parent layout llParent in xml and you want to add items in this llPaent, from list list.
for(int i=0;i<list.size();i++)
{
LinearLayout llView=(LinearLayout)inflater.inflate(R.layout.row);
//get view id and set values
TextView txt=(TextView)llView.findViewById(R.id.text);
}

A ListView is a good view for displaying several similar items. Here is a tutorial (Other views with adapters are good too, such as GridView or Gallery).
You will probably want to create your own adapter for the list, so you can display all three views (checkbox, image and text) as one item, but there are lots of examples on that available on the net as well as here on SO.

Inflator in Android Application Development

Can anybody please tell What Inflator is and how it is being used in an Android application?
I don't know the exact use of it and Why it is being used.

My preferred way to handle inflation:
//First get our inflater ready, you'll need the application/activity context for this
LayoutInflater mInflater;
mInflater = LayoutInflater.from(mContext);
//Inflate the view from xml
View newView = mInflater.inflate(R.layout.my_new_layout, null);
//Then you'll want to add it to an existing layout object
mMainLayout.add(newView);
//Or perhaps just set it as the main view (though this method can also
// inflate the XML for you if you give it the resource id directly)
setContentView(newView);
Basically, you use it to inflate existing xml layouts at runtime. Usually you go ahead and insert those new views into previously defined ViewGroups or List objects.

Not quite sure what you mean, but if its related with inflating views, its used to load layout xml files into your application. e.g by
View myWelcome = View.inflate(this, R.layout.welcome, null);
Its easier and consider best practice to have you view definition inside layout xml files, instead of creating your views fully by code.

layout inflator is used to return a java object of your complete layout
suppose you have a layout xml file in which the root element is relative layout and it contains a imageview and textview then using layout inflator you can return a view object that refers to entire layout.
this basically is used in list view and grid view to plug into them a layout object of single row or element which is to be repeated.

you were asking for use of Inflator..
basically when you want to use two xml files in one java class ,inflator is used and its code is simple which is given below..
TextView text;
View layout;
LayoutInflater inflator=getLayoutInflater();
layout =inflator.inflate(R.layout.new_xml_that you want to use in that java class,null);
text=(TextView)layout.findViewById(R.id.text);
text.setText("progressing");
here i use textview,this is present in next xml with id=text
thats it..
if you find this worthy then please like this..
thanks
