android studio how to set string Id

Question

I want to set ID for a dynamically added textview in a loop. I found out that the only function they have is setId with int parameter. How can we set the ID with string, perhaps like this:

LinearLayout linearLayout = findViewById(R.id.linearLayout);
for(int i=0; i<10; i++) {
    TextView textView = new TextView(this);
    textView.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
    textView.setText("Text Number "+i);
    textView.setId("@+id/myTextView"+i); // => Is this possible? This will cause error because setId needs INT type parameter.

    linearLayout.addView(textView);
}

I don't want to use resource file because it's not dynamic. Is it possible?

You cannot set id with char or string. Only int will work. However you can use the setTag() API. You can later do getTag() or use findViewWithTag
