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:

First declare your inflater. LayoutInflater inflater = (LayoutInflater)getApplicationContext().getSystemService (Context.LAYOUT_INFLATER_SERVICE); Identify and inflate the new view you seek to project on the current view. View view = inflater.inflate(R.layout.new_layout,null); 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. ^,^
