You seem to not understand the difference between an AdapterView widgets and basic ViewGroups .. There is no way to set one listener with a position argument out-of-the-box on LinearLayout..

You can however subclass it, expose an interface and iterate over child elements. On each one of them set an OnClickListener which just calls the implementation of your exposed interface along with index of this element in the iteration.

public class MyLinearLayout {

    private OnItemClickListener mListener;

    public interface OnItemClickListener {
        void onClick(int position);
    }

    public void setOnItemClickListener(OnItemClickListener listener){
        mListener = listener;
        for (int i = 0; i < getChildCount(); i++) {
            getChildAt(i).setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    listener.onClick(i);
                }
            });
        }
    }
}

One way you can do that is

for(int i= 0 ; i < linearLayout.getChildCount() ; i++){
   View view  = linearLayout.getChildAt(i);
   view.setTag(i);
   view.setOnClickListener(new OnClickListener(){

        @Override
        public void onClick(View v){
           int position = (int) v.getTag();
        }
   });
}

other way is to extends LinearLayout and create one with this functionality

first set id of LinearLayout in your XML. and then set OnClickeListener on this LinearLayout from your code.

Try This.

 <LinearLayout
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:orientation="horizontal"
       android:id="@+id/linearLayout">

       ...

   </LinearLayout>

 LinearLayout linearLayout = (LinearLayout) findViewById(R.id.linearLayout);

 linearLayout.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    // Do what you want.
                }
            });
