รายละเอียดของการตอบ ::
อ่อค่า แก้เรียบร้อยแล้วคะ ขอบคุณนะคะ ^^
แต่ว่าตอนนี้มันติดที่ try อะคะ แบบว่ามันไม่เข้า try ให้อะค่ะ แล้วไปเข้า catch เลย
Code (Android-Java)
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().permitAll().build());
Toast.makeText(MyCalendarActivity.this,DMYnow, Toast.LENGTH_SHORT).show();
date = DMYnow;
HttpClient hc = new DefaultHttpClient();
HttpPost hp = new HttpPost("http://"+IP+"/promotion/ListV.php?date="+date);
HttpResponse hr = null;
BufferedReader br = null;
try {
hr = hc.execute(hp);
br = new BufferedReader(new InputStreamReader(hr.getEntity().getContent()));
String Data = "";
StringBuffer sb = new StringBuffer("");
while( (Data = br.readLine()) != null)
{
sb.append(Data);
Toast.makeText(MyCalendarActivity.this, ""+Data, Toast.LENGTH_LONG).show();
if(Data.equals("null"))
{
Check = 0 ;
Toast.makeText(MyCalendarActivity.this, "Null", Toast.LENGTH_LONG).show();
}
else{
Check = 1 ;
try {
JSONArray jArray = new JSONArray(sb.toString());
for(int g =0;g<jArray.length();g++)
{ //JSONObject json_data = null;
JSONObject json_data = jArray.getJSONObject(g);
ListV[0] = json_data.getString("date");
ListV[1] = json_data.getString("time");
ListV[2] = json_data.getString("title");
Toast.makeText(MyCalendarActivity.this, " "+ListV[0]+" "+ListV[1]+" "+ListV[2], Toast.LENGTH_LONG).show(); }
}
catch (JSONException e1) {
Toast.makeText(MyCalendarActivity.this, "IOException e1", Toast.LENGTH_LONG).show();
e1.printStackTrace(); }
}}}
catch (IOException e2) {
Toast.makeText(MyCalendarActivity.this, "IOException e2", Toast.LENGTH_LONG).show();
e2.printStackTrace(); }
