I am able to change my ListItem's text size in xml:

 android:textSize="22sp"

But instead of hard coding it in xml, how do I do it through java?

here is my adapter:

 BookAdapter adapter = new BookAdapter(getActivity(), R.layout.list_item, Library.getInstance().getBible(bible).getBook(pos).getChapters());
 setListAdapter(adapter);
 getListView().setOnItemClickListener(this);

Assign an ID to the TextView in XML:

android:id="@+id/text"

In Java:

for (int i = 0; i < adapter.getCount(); i++) 
 View item = (View) adapter.getItem(i);
 TextView text = item.findViewById(R.id.text);
 text.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 22f); //or whatever size you want

You can use custom layout xml file like this:

<?xml version="1.0" encoding="utf-8"?>
LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<TextView 
android:id="@+id/listView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="@color/black"
android:textSize="20dp" />

java code

listView.setAdapter(new ArrayAdapter<String>(this, 
android.R.layout.simple_list_item_1, 
MobileMuni.getBookmarkStore().getRecentLocations()) 
 @Override
public View getView(int position, View convertView, ViewGroup parent) 
TextView textView = (TextView) super.getView(position, convertView, parent);
textView.setTextSize(12);

return textView;
 
 );

Use this line:

tv.setTextSize(TypedValue.COMPLEX_UNIT_DIP,25);
