Question

我遇到需要接收常量分块JSON响应的情况，每次收到响应时我需要解析JSON以更新操作当前状态的UI。

我找不到单独收到每个回复的直接方法，并将信息发回UI，直到响应完成接收为止。

如果有人能对此有所了解，我将不胜感激!!

我有101种不同的方式来进行http调用..我只需要正确的方法来读取响应。

- 编辑 - 只是添加到此。我遇到的问题不是读取JSON数据，而是分别获取每个数据块并在每个块之间回发到UI - NathofGod 27秒前编辑

        DefaultHttpClient http_client = new DefaultHttpClient();
        HttpGet httpGet = new HttpGet(url);
        HttpResponse response = http_client.execute(httpGet);

        StatusLine statusLine = response.getStatusLine();
        int statusCode = statusLine.getStatusCode();
        HttpEntity entity = response.getEntity();

        InputStream in = entity.getContent();
        StringBuffer out = new StringBuffer();
        byte[] b = new byte[4096];
        int n =  in.read(b);
        out.append(new String(b, 0, n));        
        String resultdata = out.toString();

Answer 1

int n = in.read(b);
while(n>0){
    out.append(new String(b, 0, n);
    n = in.read(b);
}

String resultData = out.toString();
