我想将这两个 TextView 订单和费用保存到我的sql数据库中，请帮助我谢谢，我正在使用wampserver与3 php文件将它们连接到我的wampserver。因为复制和粘贴php文件是不可能的，因为有太多的代码。是否有人愿意给我一步一步的指导，就像我首先要在我的数据库中创建一个包含成本和订单的表.. < em>我如何编码，以便我可以将文本发送到wampserver
答案 0 :(得分：0)
使用Asynktask保存您的数据，如下所示
class SaveData extends AsyncTask<String, String, String>{
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
pDialog = new ProgressDialog(YourActivity.this, AlertDialog.THEME_HOLO_LIGHT);
pDialog.setMessage("Please wait..");
pDialog.setCancelable(true);
pDialog.setIndeterminate(false);
pDialog.show();
}
@Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
try{
String data = URLEncoder.encode("ordersParameterName", "UTF-8")
+ "=" + URLEncoder.encode(orders, "UTF-8");
data += "&" + URLEncoder.encode("costParameterName", "UTF-8")
+ "=" + URLEncoder.encode(cost, "UTF-8");
URL url = new URL("your url here");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write( data );
wr.flush();
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuilder sb = new StringBuilder();
String line = null;
// Read Server Response
while((line = reader.readLine()) != null)
{
sb.append(line);
break;
}
return sb.toString();
}catch(Exception e){
return new String("Exception: " + e.getMessage());
}
}
@Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
pDialog.cancel();
//your success to insert value
}
}
您可以点击提交按钮
来调用它new SaveData().execute();
