Why does .addView throw this parent/child exception?

Question

Hello!
I'm trying to create dynamic TextViews inside a LinearLayout within my main activity. The program is (supposed to be) pushing out TextView's from resultrow XML to activity_fivethreeone XML as required. The line parentLayout.addView(textView); is throwing this error;

The specified child already has a parent. You must call removeView() on the child's parent first.

I've tried answers from similar questions but getting no wins.

class:

try {
    LinearLayout parentLayout = (LinearLayout)findViewById(R.id.linLayout);
    LayoutInflater layoutInflater = getLayoutInflater();
    View view;
    for(int counter=0;counter<=theWeeksList.size();counter++){
        view = layoutInflater.inflate(R.layout.resultrow, parentLayout, false);
        TextView textView = (TextView)view.findViewById(R.id.resultRow);
        textView.setText(theWeeksList.get(counter));
        parentLayout.addView(textView);
    }
}

I was trying to use removeView() but couldn't get it to stick.

Any help will be much appreciated!
Thanks!

textView has already as parent view, as matter of fact you are able to look for it with findViewById successfully. So this line:

parentLayout.addView(textView);

is causing the exception. You probably want to add view to parentLayout

parentLayout.addView(view);

since it has been just created, it has no parent and can be added as child

You're trying to add an EditText that already belongs to an existing ViewGroup.

Remove the line

parentLayout.addView(textView);

from your code. You don't need to do that. Replace it with

parentLayout.addView(view);
