I would like to read an array in from a file that is in the format of
{{"text text text","text text","also text"},{"text text text","text text","also text"},{"text text text","text text","also text"}}
from a file and don't know the best way to do it. How can I efficiently split the line in order to add them to an ArrayList in a for loop?
string.split(",\\{") will return an array of entries in the line separated by commas. You could use this and some nested fors to fill your ArrayLists. Although if you're saving to Android, you should be using SharedPreferences and saving sets of items.
Example of shared prefs:
// Adds an item to the shared preferences list
public void addItemToList(String item){
SharedPreferences itemList = getSharedPreferences(PREFS_NAME, 0);
Set<String> items = itemList.getStringSet(filter, new HashSet<String>());
Set<String> tItems = new HashSet<String>();
tItems.addAll(items);
tItems.add(item);
SharedPreferences.Editor editor = itemList.edit();
editor.putStringSet(filter, tItems);
editor.commit();
}
Example of nested for:
String[] lineArray = line.split(",\\{");
for(int i =0; i < lineArray.length ; i++){
String[] currentArray = lineArray[i].split(",");
for(int j = 0; j < currentArray.length ; j++){
....
