我正在使用 HTTPPost 将值发送到服务器。该脚本适用于我下面的内容。但是，如果我将名称值对更改为此，我会强制关闭：

nameValuePairs.add(new BasicNameValuePair("id", idOfTextView.getText().toString()));

这是没有读取文本视图的代码：

 String url_select = "http://mydomain.com/get.php";
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(url_select);
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
    nameValuePairs.add(new BasicNameValuePair("id", "1"));
    try {
        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        //read content
        is =  httpEntity.getContent();                  
    } catch (Exception e) {
        Log.e("log_tag", "Error in http connection "+e.toString());
    }

    try {
        BufferedReader br = new BufferedReader(new InputStreamReader(is));
        StringBuilder sb = new StringBuilder();
        String line = "";
        while((line=br.readLine())!=null){
            sb.append(line+"\n");
        }
        is.close();
        result=sb.toString();               
    } catch (Exception e) {
        Log.e("log_tag", "Error converting result "+e.toString());
    }
    return null;

看起来我的评论是答案，请确保idOfTextView它是非空的。
