Do you want to add all the ArrayList data into a single textview? — Dentor

you could concat the arrayList values into a string and then set that string value to textView. — 7geeky

If you want each string in each textview, you can use something like:

for (int i = 0; i < N; i++) { final TextView rowTextView = new TextView(MainActivity.this); // getting respective string val from list rowTextView.setText(" row value #" + al_getAllProductSize.get(i)); ll_textViewObj.addView(rowTextView); // save a reference to the textview for later myTextViews[i] = rowTextView; }

Try this one . hope it will help you.

final int X = 5; // total number of textviews to add final TextView[] myTextViews = new TextView[X]; // create an empty array; for (int i = 0; i < X; i++) { // create a new textview final TextView rowTextView = new TextView(this); // set value in textview rowTextView.setText("row value #" + i); // add the textview to the linearlayout ll_textViewObj.addView(rowTextView); // save a reference to the textview for later myTextViews[i] = rowTextView; }

Try this

int size = al_getAllProductSize.size(); TextView[] myTextViews = new TextView[size]; for (int i = 0; i < size; i++) { myTextViews[i] = new TextView(MainActivity.this); rowTextView.setText( al_getAllProductSize.get(i)); ll_textViewObj.addView(myTextViews[i]); }
