Android setter of String array

Question

I've got simple setter and getter of string array. I want to use setter to put some retrieved json info + same text to array. When I use this code:

met.setPlacepic(new String[]{"http://dfsdfsdfsf/" + json.getString("source")});

it looks like setter put only one string to array, despite there is many more data.

Declaration is simple:

public String[] placepic

and the setter is also simple:

public void setPlacepic(String[] placepic) {
        this.placepic = placepic;
}

Does anybody know the reason of this?

It did put one string because you only gave one string. What did you expect? — iTurki

This is not an Android question but more about a question about Java's arrays. Have a look at and you'll find out how they work: docs.oracle.com/javase/tutorial/java/nutsandbolts/arrays.html — Simone Casagranda

this method is inside of loop which retrevie more than one string — bakusek

So what? what you do in each iteration is provide a new array to your setPlacepic(). Do you want to add to it instead? — iTurki

If the number of strings is fixed (you know exactly how many element you would have in the array), then you could use String Arrays:

String[] placepic = new String[20]; //20 strings
//Then, in your loop:
placepic[i] = yourData;

If you do NOT know how many strings in your data, You should use List:

List<String> placepicList= new ArrayList<String>();
//Then, in your loop:
placepicList.add(yourData);
//Then after the loop, you get the array
String[] placepic = placepicList.toArray(new String[placepicList.size()]);
