How can i pass a Double[] array to another activity

Bundle object doesn't let me pass a Double[] array because it require a double[] array. i'm not able to cast double[] to Double[] and I don't know what to do.

Help me please.

Solution

  • You could loop through the Double array and populate the double array by assigning to every value the output of Double.doubleValue(); Once that is done you can put your double[] array in the Bundle

    Double D[];
double d[];
for(int i=0 ; i<D.length ; ++i) {
    d[i] = D[i];
}

    Of course I did not initialize the variables but it's merely to give an example
