Android, Add New Element on the Fly with LayoutInflater

Adding new element in Android view not as easy as using jquery.js and add an element
into html document. After googling for a while i found out that LayoutInflater is the tool.

I found good answer in StackOverflow pointing this out:

  1. First declare your inflater.
    LayoutInflater inflater = (LayoutInflater)getApplicationContext().getSystemService
      (Context.LAYOUT_INFLATER_SERVICE);
  2. Identify and inflate the new view you seek to project on the current view.
    View view = inflater.inflate(R.layout.new_layout,null);
  3. You would want to add your new inflated view to your layout.
    main.addView(view);

Plug that code into my app becomes:

#
# ...
 
LayoutInflater li = (LayoutInflater) LayoutInflater.from(getApplicationContext() );
View cv = li.inflate(R.layout.list_targetitem, null);
TextView item1 = (TextView) cv.findViewById(R.id.targetlist_tview);
 
item1.setText( "TARGET " + MyActivity.indexTarget + "\n" + locationName );
 
#

And that code works just the same as jquery.js/HTML. But one question was arised,
how i got the id of the element? Well no luck of finding how to set new element' ID attribute.
One of the StackOverflow shares or somewhere i don`t remember at all did mention that
to hold the new element into HashMap that we could easily retreived later.

This is the way i done it

public class MyActivity extends AppCompatActity implements ... {

    LinearLayout targetHashMapView;

    @Override
    protected void onCreate(Bundle svdInstance){
        ...
        // Noticed that R.id.init_target_location is pointing to a LinearLayout tag/element
        // inside MyActivity layout xml file
        targetHashMapView = (LinearLayout) findViewById(R.id.init_target_location);
        ...
    }
}


Thus adding the new element, append the R.id.init_target_location LinearLayout element. ^,^
