volleyで配列をPOSTしたいとき

Androidデベロッパーの強い味方のVolleyで配列をPOSTする場合のサンプルです。

TestActivity

public class TestActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Request request = new Request<String>(Request.Method.POST, "URL", new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
            }
        }) {
            @Override
            protected Response<String> parseNetworkResponse(NetworkResponse networkResponse) {
                return Response.success(new String(networkResponse.data), getCacheEntry());
            }

            @Override
            protected void deliverResponse(String response) {

            }

            @Override
            protected Map<String, String> getParams() throws AuthFailureError {
                Map<String,String> postParams = new HashMap<String, String>();
                //POSTパラメーターに配列入れる
                postParams.put("hoge[0]","param1");
                postParams.put("hoge[1]","param2");
                return postParams;
            }

        };
        request.setRetryPolicy(new DefaultRetryPolicy(
                DefaultRetryPolicy.DEFAULT_TIMEOUT_MS,
                DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
        request.setTag("TAG");

        RequestQueue requestQueue = Volley.newRequestQueue(this);
        requestQueue.add(request);
    }
}
