How to Display the text in Reverse from char to String

Question

I tried to display the text but it is displaying in wrong view. I want to display the Textview in reverse. I tried this code

String subMenuId = (String) key[position];
String subMenuName = subMenuTable.get(subMenuId);
for (int x = 0; x < subMenuName.length(); x++) {
    int splitword = subMenuName.charAt(x);
    char c = (char) splitword;
    TextView product = new TextView(con);
    product.setText(String.valueOf(c));
    product.setRotation(-90);
    holder.tv.setGravity(Gravity.CENTER_VERTICAL);
    product.setTextSize(12);
    holder.tv.setPadding(5,0,5,0);
    product.setTextColor(Color.BLACK);
    product.setTypeface(null, Typeface.BOLD);
    holder.tv.addView(product);
}

Do you want a single `TextView` with 90° rotated? or each character as textview as in your code? — Let'sRefactor, Feb 17 '16 at 12:31
see the image i uploaded. it shows like "nairategeV". its actually vegetarian. but it's displaying like that. i want to display it as Vegetarian in that image — Dev Tamil, Feb 17 '16 at 12:33
change your loop to `for (int x = subMenuName.length() -1; x >=0 ; x--)` :) — Let'sRefactor, Feb 17 '16 at 12:36

Just reverse your loop

i.e.

for (int x = 0; x < subMenuName.length(); x++)

to

for (int x = subMenuName.length() -1; x >=0 ; x--)

Hope it helps

When you iterate from 0 ⇢ n first char get referred first and will be added to top. since you want it in reverse, iterate n ⇢ 0
