Clone textview to append it to a ViewGroup

Question

I have a ViewGroup defined in XML with a view inside, at onCreate time I'd like to have a variable of those.
I don't want to go through the hassle of using a listview+adapter cause its clearly overkill as I know the list won't change since onCreate()
This is more or less the code I'd like to have.

TextView mytextview = myViewGroup.findViewById(R.id.mytext);

for(String test : strings){
  mytextview = mytextview.clone();
  mytextview.setText(test);
  myViewGroup.addView(mytextview);
}

But it is not working.

Answer 1

Using code of Mathias Lin and using the hint from javahead76:

LinearLayout x = (LinearLayout) findViewById(R.id.container); 

    for (int i = 0; i < 5; i++) {
        View c = LayoutInflater.from(this).inflate(R.layout.singlerow, x);  
        TextView t = ((TextView)findViewById(R.id.textView1));
        t.setId(i+10000);
        t.setText("text"+i);            
    }
    TextView b = (TextView) findViewById(10003);
    b.setText("10003");

Answer 2

If you do this, you will most likely get the exact same id for every view created this way. This means doing things like ((TextView)v).setText("some text"); will be called on every TextView previously inflated from the same layout. You can still do it this way, but you should call setId() and have some reasonable method for ensuring you do not get the same id twice in a row - incrementation or universal time, etc.

Also, I think Android reserves a certain range of id's for dynamically created id's. You might avoid ID's in this range; but honestly, I don't know the id system works so I could be wrong on this point.

Answer 3

Maybe use an inflater, and put the textview in an external layout file:

View v = LayoutInflater.from(this).inflate(R.layout.textview_include, null);
viewGroup.addView(v);
