Arbeits Ich möchte den Spinner Wert php passieren und einige Ergebnis und zeigt in meine Textview zu bekommen. Wenn ich Toast verwende, um den Selected-Wert anzuzeigen, funktioniert es perfekt. Aber während ich den Wert an die php-Datei übergebe, werde ich getroffen. Ich habe es versucht. kann einige mein Problem beheben.Beim Senden Spinner Wert auf PHP-Datei erstmals seine nur
Java-Datei:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().hide(); //<< this for hide title bar
setContentView(R.layout.sales_order);
fg.setOnItemSelectedListener(
new AdapterView.OnItemSelectedListener() {
public void onItemSelected(
AdapterView<?> parent, View view, int position, long id) {
if(goods_name1.getSelectedItem() !=null && goods_name1.getSelectedItem() !=""){
// WebServer Request URL
String serverURL = "http://IP/fs/getProductOneStock.php";
// Use AsyncTask execute Method To Prevent ANR Problem
new LongOperation().execute(serverURL);
}
}
public void onNothingSelected(AdapterView<?> parent) {
showToast("Spinner1: unselected");
}
});
}
// Class with extends AsyncTask class
private class LongOperation extends AsyncTask<String, Void, Void> {
// Required initialization
private final HttpClient Client = new DefaultHttpClient();
private String Content;
private String Error = null;
private ProgressDialog Dialog = new ProgressDialog(Sales_Order.this);
String data ="";
int sizeData = 0;
TextView pro_stock1 = (TextView)findViewById(R.id.tv_stock1);
Spinner fgStock = (Spinner)findViewById(R.id.spinner1);
protected void onPreExecute() {
// NOTE: You can call UI Element here.
//Start Progress Dialog (Message)
Dialog.setMessage("Please wait..");
Dialog.show();
try{
// Set Request parameter
data +="&" + URLEncoder.encode("data", "UTF-8") + "="+fgStock.getSelectedItem();
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
// Call after onPreExecute method
protected Void doInBackground(String... urls) {
/************ Make Post Call To Web Server ***********/
BufferedReader reader=null;

// Send POST data request
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();
// Get the server response
reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuilder sb = new StringBuilder();
String line = null;
// Read Server Response
while((line = reader.readLine()) != null)
{
// Append server response in string
sb.append(line + "");
}
// Append Server Response To Content String
Content = sb.toString();
}
catch(Exception ex)
{
Error = ex.getMessage();
}
finally
{
try
{
reader.close();
}
catch(Exception ex) {}
}
return null;
}
protected void onPostExecute(Void unused) {
// NOTE: You can call UI Element here.
// Close progress dialog
Dialog.dismiss();
if (Error != null) {
pro_stock1.setText("Output : "+Error);
} else {
// Show Response Json On Screen (activity)
pro_stock1.setText(Content);
/****************** Start Parse Response JSON Data *************/
String OutputData = "";
JSONObject jsonResponse;
try {
/****** Creates a new JSONObject with name/value mappings from the JSON string. ********/
jsonResponse = new JSONObject(Content);
/***** Returns the value mapped by name if it exists and is a JSONArray. ***/
/******* Returns null otherwise. *******/

for(int i=0; i < lengthJsonArr; i++)

}
/****************** End Parse Response JSON Data *************/
//Show Parsed Output on screen (activity)
//jsonParsed.setText(OutputData);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
meine PHP-Datei
<?php
require "db_config.php";
$Goods_name=$_POST['Goods_name'];
$sql = "select goods_min_level from Finish_goods_mas where Goods_name='".$Goods_name."'";
$stmt = sqlsrv_query($conn, $sql);
if($stmt === false) {
die(print_r(sqlsrv_errors(), true));
}
while($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
//echo $row['cus_id']."<br />";
$json['Finish_goods_mas'][]=$row;
}
sqlsrv_free_stmt($stmt);
echo json_encode($json);
?>
nach Änderungen von doInBackground machen und onPreExecute() der Spinner Wert auf PHP-Datei passiert nicht auch bekomme ich nicht Ergebnis von php zurück
Durch 'ShowProStock' Methode, da UI-Elemente Aktualisierung von 'doInBackground' –
wie kann ich – Karthi
ShowProStock() auszuführen ist Methode verwenden, um die JSON von Server zu erhalten – Karthi
