How to change the android:text of a textView

Question

I am having trouble changing the text inside my textview. I want to have the textview contain the string "foo \n bar \n foo2 \n bar2" and I want to be able to add and take away lines from the textview. I can manually type in "foo \n bar" in the android:text, but I would like to edit it from my class file and append items added from an ArrayList of Strings.

It want's to take in a CharSequence, but converting from String to CharSequence doesn't seem to make it very happy.

A `String` is a `CharSequence`. You shouldn't have to cast anything. — Dan Harms, Oct 01 '14 at 16:45

You should be able to pass a string to the TextView's setText method once you have a reference to it...

TextView text=(TextView)findViewById(R.id.textviewID);
text.setText("foo \n bar");

will work (replace R.id.textviewID with the id of your control, of course)

You can convert CharSequence to string just by invoking toString() method on CharSequence object.

Further you can set Text on TextView by using setText() method as follow:

TextView tv=(TextView)findViewById(R.id.textview1);
tv.setText(charSequenceObj.toString());

If you are trying to print "\n" too (as your question is not bit clear to me.) use escape sequence characters. so for "\n" it will be "\n"
