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,如果我改名字值对这个我得到一个强制关闭:Android NameValuePair不接受字符串
nameValuePairs.add(new BasicNameValuePair("id", idOfTextView.getText().toString()));
这是没有它读取的TextView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;
logcat中的错误是什么?另外,确保'idOfTextView'非空。 – wsanville
