I'd like to try to set string array as text of the textview. How can I do that?
Below is what I've tried so far:
String[] word = { "Pretty", "Cool", "Weird" };
tv.setText( word.length );
But it's throwing some errors. I'm new to Android/Java

word.length gives you length of the array, not the content. You mean to set the content to tv. You can use Arrays#toString method: -
String[] word = { "Pretty", "Cool", "Weird" };
// Prints [Pretty, Cool, Weird]
tv.setText(Arrays.toString(word));
// Prints Pretty, Cool, Weird
tv.setText(Arrays.toString(word).replaceAll("\\[|\\]", ""));

TextView.setText() takes a CharSequence as the first argument so the compiler will complain if you pass in an int in the case of word.length.
Using an enhanced for-loop:
String[] word = { "Pretty", "Cool", "Weird" };
StringBuilder builder = new StringBuilder();
for (String s: word) {
builder.append(s);
builder.append(" ");
}
tv.setText(builder.toString().trim()); // .trim to remove the trailing space.
or since Java 8:
tv.setText(String.join(" ", word));
Arrays.toString(word);??
