Question

I’m stucked with filling an Array dynamic.

I can’t find the solution. Normal I would fill the array just by any loop.

It’s not working in this case I really spent hours to find a solution.

I found an example to use a custom list in android. works fine.

I create a object Test.

public class Test {
public int icon;
public int PB;
public String title;
public Test(){
    super();
}

public Test(int icon, String title, int PB) {
    super();
    this.icon = icon;
    this.title = title;
    this.PB = PB;
}

}

and fill it static here works fine. But I don’t get how to fill it dynamic.

Test test_data[] = new Test[]
    {
        new Test(R.drawable.ic_launcher, "Test 1", 10),
        new Test(R.drawable.ic_launcher, "Test 2", 100)
    };

Answer 1

dynamic assigning of data to an array as is follows:

 Test [] test_data = 
{
    new Test(R.drawable.ic_launcher, "Test 1", 10),
    new Test(R.drawable.ic_launcher, "Test 2", 100)
};

EDIT:

this can be done only in the first time you instance the array. if you already know how big the array is gonna be you should do this:

Test [] test_array = new Test[size];
for (int i=0; i<size; i++) {
    //DO STUFF
}

if you don;t know the size from the start what you should do is use a ListArray and then convert it to a simple array (or not), here is the code for that:

ListArray<Test> list = new ListArray<Test>();
// INSERT VALUES

public Test[] listToArray(ArrayList<Test> list) {
     Test [] result = new Test [list.size());
     for (int i = 0; i<list.size(); i++) {
        result[i] = list.get(i);
     }
     return result;
}
