Question

I’m dealing with doubles and looking for the “double” equivalent of this…

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("lat",lat));
nameValuePairs.add(new BasicNameValuePair("lng",lng));

edit// I’m making a HTTP request, I think need to map the lat value to a php lat variable and the long to a php variable.

Thanks!

If you have to use NameValuePair, there are two possible solutions.

You can convert a Map to a List of NameValuePair:

List<NameValuePair> convertParameters(Map<String, Double> parameters) {
    List<NameValuePair> result = new ArrayList<NameValuePair>();

    for (Entry<String, Double> entry : parameters.entrySet()) {
        result.add(new BasicNameValuePair(entry.getKey(), entry.getValue().toString()));
    }

    return result;
}

Or you can implement a new NameValuePair to handle Double values:

public class DoubleNameValuePair implements NameValuePair {

    String name;

    double value;

    public DoubleNameValuePair(String name, double value) {
        this.name = name;
        this.value = value;
    }

    @Override
    public String getName() {
        return name;
    }

    @Override
    public String getValue() {
        return Double.toString(value);
    }

}

In the latter case, you can use a List of NameValuePair that can be passed directly to UrlEncodedFormEntity’s constructor:

List<NameValuePair> parameters = new ArrayList<NameValuePair>();
parameters.add(new DoubleNameValuePair("lat", 1.0));
parameters.add(new DoubleNameValuePair("lng", 2.0));
