我嘗試了所有在此處找到的解決方案,但似乎沒有任何與我一起工作。我是Android新手,這是我的問題。將數組傳遞給帶有JSON的Android應用程序
我有這個PHP腳本獲取MySQL數據,並將其傳遞到一個數組
<?php
$con = mysqli_connect("localhost", "username", "passwod", "database");
$result = array();
$getacceptedsotres = mysqli_query($con, "SELECT * FROM offer WHERE
type='sale' AND approved = 'approved'");
while($rowgetid = mysqli_fetch_assoc($getacceptedsotres)){
$storeid = $rowgetid['id'];
$getstores = mysqli_query($con, "SELECT * FROM sale WHERE offerid =
'$storeid' ");
while($row = mysqli_fetch_assoc($getstores)){
array_push($result,array(
'title'=>$row['title'],
'offerto' => $rowgetid['offerto'],
'type' => $rowgetid['type'],
'percentageoff'=>$row['percentageoff']
));
}
}
echo json_encode(array($result));
當PHP腳本執行的時候給了我這樣的:
[[{ 「稱號」: 「所有飲料40%優惠」,「有效」:「06/29 /2016」,「type」:「sale」,「percentageoff」:「40%」},{「title」:「30% selected> items「,」offerto「:」07/31/2016「,」type「:」sale「,」percentageoff「:」30%「}, {」title「:」45%off on selected items「, 「offerto」:「07/08 /2016」,「type」:「sale 「,」percentageoff「:」45「}]]
我的問題是當我想要將此結果傳遞到android studio中的列表。
這是
公共類銷售擴展AppCompatActivity實現AsyncResponse {
private ArrayList<GetSale> saleList;
private ListView lvSale;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sale);
ImageLoader.getInstance().init(UILConfig.config(Sale.this));
PostResponseAsyncTask taskRead = new PostResponseAsyncTask(Sale.this, this);
taskRead.execute("http://....php");
}
@Override
public void processFinish(String s) {
saleList = new JsonConverter<GetSale>().toArrayList(s, GetSale.class);
BindDictionary<GetSale> dict = new BindDictionary<GetSale>();
dict.addStringField(R.id.tvSaleAmount, new StringExtractor<GetSale>() {
@Override
public String getStringValue(GetSale getSale, int position) {
return getSale.title;
}
});
dict.addStringField(R.id.tvType, new StringExtractor<GetSale>() {
@Override
public String getStringValue(GetSale getSale, int position) {
return getSale.type;
}
});
FunDapter<GetSale> adapter = new FunDapter<>(
Sale.this, saleList, R.layout.layout_sale, dict);
lvSale = (ListView)findViewById(R.id.lvSale);
lvSale.setAdapter(adapter);
}
}
所以,當我運行應用程序並嘗試列出的結果我在我的課堂上使用的代碼m從我的PHP腳本得到我在Android工作室得到這個長的錯誤,但我認爲這是導致錯誤的主線

任何幫助,將不勝感激。 預先感謝您
在您的PHP代碼中將'echo json_encode(array($ result));'改爲'echo json_encode($ result);'。 –
@PrerakSola omg它的工作..我有一個不同的數組類型,它不與echo json_encode($結果);但我改變了陣列,忘了再次嘗試這個回聲謝謝 –
高興地幫助.. :) –
