You can set id of any controls by

btn.setId(integer value) at runtime.

If you don't want to set id then there is no issue

Also when you create new view then you have to set its layout parameters(Height, Width)

for example

btn.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

So whole process is like

Button btn = new Button(Context);
btn.setId(1);
btn.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
btn.setText("Dynamic button");
btn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
             Toast.makeText(v.getContext(),"Dynamic button is clicked", 3000).show();
            }
        });

Try this code.

Button text = new Button(this);

text.setId(1);
text.setText("text here");
ll.addView(text);
text.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub
        int id = arg0.getId(); // you get ID of your dynamic button
        Toast.makeText(getApplicationContext(), "Dynamic textview!", Toast.LENGTH_SHORT).show();
    }
});

In that "ll" is a Layout and that add button. after that you use anytime for click execute that clickListener code.

you can simply use this

Button main= new Button(this);
            main.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub

                }
            });

and there is main.setId(pass here int value); to set id but i think you will not need it
