Creating dynamic controls

I am t开发者_Python百科rying to create a screen with some dynamic controls, well radio buttons to be precise purely for learning purposes.

I have managed to add the radio button by referencing the radio group in the main.xml file.

RadioGroup rg = (RadioGroup)findViewById(R.Id.types);
RadioButton rb = new RadioButton(this);
rb.setText("some text!");
rg.addView(rb);

What I cannot figure out is how do I set the id of the radio button?

If use rb.setId() it wants an integer? I am trying to basicaly do the xml bit dynamically:

---

rb.setId(int) is how you would set the ID. You say "it wants an integer?" as if you find that strange. All View IDs are integers so what else would you expect?

---

well if you set it in the xml file as

The yadda appears in the R.java file as an autogenerated number. Therefore I was not sure that it was correct to assign any old number seeing as you pass text in the xml.
