Android : when i put 'addView(..) inside a forloop i got error..Here we go

Question

Here the code sample:

     TableLayout ll = (TableLayout)findViewById(R.id.dyn_lyr);

also same with LinearLayout

    //LinearLayout ll = (LinearLayout)findViewById(R.id.dyn_lyr);

    TextView tv1 = (TextView) findViewById(R.id.testEditText);
    tv1.setText("SomeTextGoesHere");

    for(int i=1 ; i<= 5 ; i++){
        ll.addView(tv1);
            }

the LinearLayout/Table is inside ScrollView!

Answer 1

You should create TextView Dynamically and add in ll...

for(int i=1 ; i<= 5 ; i++){
    TextView tv1 = new TextView(getApplicationContext());
    tv1.setText("SomeTextGoesHere");
    ll.addView(tv1);
}

Answer 2

There is not enought info but I guess that Tv1 already has a parent . I guess that you should add new TextView every time . Try this one. Ok then create brand new TextView

  for(int i=1 ; i<= 5 ; i++){
       TextView tv1 = new TextView(this);
       tv1.setText("SomeTextGoesHere");
       ll.addView(tv1);
   }

Answer 3

If you are using findViewById, the resulting view is already a part of your layout and has a parent. Each view can only be added to a ViewGroup once. You need to be making new TextViews and adding those to your LinearLayout. You can do this either via the TextView constructor or a LayoutInflater with a separate xml layout.
