來自伺服器的布林變數響應，帶有 json 請求

你可以在一個以下定製類

private final String PROTOCOL_CONTENT_TYPE = String.format("application/json; charset=%s", PROTOCOL_CHARSET);

    public BooleanRequest(int method, String url, String requestBody, Response.Listener<Boolean> listener, Response.ErrorListener errorListener) {
        super(method, url, errorListener);
        this.mListener = listener;
        this.mErrorListener = errorListener;
        this.mRequestBody = requestBody;
    }

    @Override
    protected Response<Boolean> parseNetworkResponse(NetworkResponse response) {
        Boolean parsed;
        try {
            parsed = Boolean.valueOf(new String(response.data, HttpHeaderParser.parseCharset(response.headers)));
        } catch (UnsupportedEncodingException e) {
            parsed = Boolean.valueOf(new String(response.data));
        }
        return Response.success(parsed, HttpHeaderParser.parseCacheHeaders(response));
    }

    @Override
    protected VolleyError parseNetworkError(VolleyError volleyError) {
        return super.parseNetworkError(volleyError);
    }

    @Override
    protected void deliverResponse(Boolean response) {
        mListener.onResponse(response);
    }

    @Override
    public void deliverError(VolleyError error) {
        mErrorListener.onErrorResponse(error);
    }

    @Override
    public String getBodyContentType() {
        return PROTOCOL_CONTENT_TYPE;
    }

    @Override
    public byte[] getBody() throws AuthFailureError {
        try {
            return mRequestBody == null ? null : mRequestBody.getBytes(PROTOCOL_CHARSET);
        } catch (UnsupportedEncodingException uee) {
            VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s",
                    mRequestBody, PROTOCOL_CHARSET);
            return null;
        }
    }
}

將此用於你的活動

try {
        JSONObject jsonBody;
        jsonBody = new JSONObject();
        jsonBody.put("Title", "Android Demo");
        jsonBody.put("Author", "BNK");
        jsonBody.put("Date", "2015/08/28");
        String requestBody = jsonBody.toString();
        BooleanRequest booleanRequest = new BooleanRequest(0, url, requestBody, new Response.Listener<Boolean>() {
            @Override
            public void onResponse(Boolean response) {
                Toast.makeText(mContext, String.valueOf(response), Toast.LENGTH_SHORT).show();
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Toast.makeText(mContext, error.toString(), Toast.LENGTH_SHORT).show();
            }
        });
        // Add the request to the RequestQueue.
        queue.add(booleanRequest);
    } catch (JSONException e) {
        e.printStackTrace();
    }
