Android ArrayList with 4 params

Question

I'm creating own List with 4 parameters. I have an example with standard list with 2 parameters.
How can I declare ArrayList for 4 parameters and not 2?

ArrayList<Map<String, String>> list = buildData();
String[] from = { "name", "purpose" };
int[] to = { android.R.id.text1, android.R.id.text2 };

Create a class that contains four parameters. for example:

public class MyClass {

    public String param1;

    public String param2;

    public String param3;

    public String param4;
}

Then, declare your arraylist as:

ArrayList< MyClass > list = buildData();

String[] from = { "name", "purpose", .... };

    int[] to = { android.R.id.text1, android.R.id.text2, ... };

Hope that helps. :)

An implementation of Map will be appropriate here.

public class SomeClass{

    public String str1;

    public String str2;

    public String str3;

    public String str4;


}


ArrayList<SomeClass, HashMap<String, String>> map = newArrayList<SomeClass,HashMap<String, String>>();
