How to inflate one view with a layout

I have a layout defined in XML. It contains also: 

<RelativeLayout
    android:id="@+id/item"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
/>

I would like to inflate this RelativeView with other XML layout file. I may use different layouts depending on a situation. How should I do it? I was trying different variations of 

RelativeLayout item = (RelativeLayout) findViewById(R.id.item);
item.inflate(...)

But none of them worked fine.

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);

You inflate an XML resource. See the LayoutInflater doc .

If your layout is in a mylayout.xml, you would do something like:

View view; 
LayoutInflater inflater = (LayoutInflater)   getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
view = inflater.inflate(R.layout.mylayout, null);

RelativeLayout item = (RelativeLayout) view.findViewById(R.id.item);

Try this code :

  1. If you just want to inflate your layout :

View view = LayoutInflater.from(context).inflate(R.layout.your_xml_layout,null); // Code for inflating xml layout
RelativeLayout item = view.findViewById(R.id.item);

  1. If you want to inflate your layout in container(parent layout) :

LinearLayout parent = findViewById(R.id.container);        //parent layout.
View view = LayoutInflater.from(context).inflate(R.layout.your_xml_layout,parent,false); 
RelativeLayout item = view.findViewById(R.id.item);       //initialize layout & By this you can also perform any event.
parent.addView(view);             //adding your inflated layout in parent layout.

AttachToRoot Set to True

Just think we specified a button in an XML layout file with its layout width and layout height set to match_parent.

<Button xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/custom_button">
</Button>

On This Buttons Click Event We Can Set Following Code to Inflate Layout on This Activity.

LayoutInflater inflater = LayoutInflater.from(getContext());
inflater.inflate(R.layout.yourlayoutname, this);

Hope this solution works for you.!

If you are you trying to attach a child view to the RelativeLayout? you can do by following

RelativeLayout item = (RelativeLayout)findViewById(R.id.item);
View child = getLayoutInflater().inflate(R.layout.child, item, true);

With Kotlin, you can use:

val content = LayoutInflater.from(context).inflate(R.layout.[custom_layout_name], null)

[your_main_layout].apply {
    //..
    addView(content)
}

When add a layout to an Activity in Kotlin, see these steps:

  1. Add just in Activity - One layout as a parent

  2. Xml file of new

  3. Layout Give the value of R.

    val parent: LinearLayout =findViewById(R.id.stars)

    val view =
    LayoutInflater.from(applicationContext).inflate(R.layout.another, parent,false)

Where parent is not necessary, can be null But warning message will be appear

view.findViewById<ImageView>(R.id.ivTimer).setImageResource(R.drawable.t2)

Any view must be set value in this way, finally add

parent.apply {  addView(view)}
