Ask Question. up vote 30 down vote favorite. 12. I have a ArrayList that contains values in the form [ann,john]. I want to convert this

Use the method «toArray()» ArrayList mStringList= new ArrayList();
mStringList.add(«ann»);
mStringList.add(«john»);
Object[] mStringArray = mStringList.toArray();

for(int i = 0; i < mStringArray.length ; i++){
Log.d("string is",(String)mStringArray[i]);
}
or you can do it like this: (mentioned in other answers) ArrayList mStringList= new ArrayList();
mStringList.add(«ann»);
mStringList.add(«john»);
String[] mStringArray = new String[mStringList.size()];
mStringArray = mStringList.toArray(mStringArray);

for(int i = 0; i < mStringArray.length ; i++){
Log.d("string is",(String)mStringArray[i]);
}

Well in general: List names = new ArrayList();
names.add(«john»);
names.add(«ann»);

String[] namesArr = new String[names.size()];
for (int i = 0; i < names.size(); i++) {
namesArr[i] = names.get(i);
}
Or better yet, using built in: List names = new ArrayList();
String[] namesArr = names.toArray(new String[names.size()]);25
String[] array = new String[items2.size()];
items2.toArray(array);7
try this

List list = new ArrayList();
list.add(«List1»);
list.add(«List2»);

String[] listArr = new String[list.size()];
listArr = list.toArray(listArr );

for(String s : listArr )
System.out.println(s);2
I know im very late to answer this. But it will help others, I was also stucked on this. Here is what i did to get it work. String[] namesArr = (String[]) names.toArray(new String[names.size()]);2You could make an array the same size as the ArrayList and then make an iterated for loop to index the items and insert them into the array.1You can try this code String[] stringA = new String[stringArrayList.size()];
stringArrayList.toArray(stringA)
System.out.println(stringA[0]);0
