我有代碼,以使這樣的錯誤java.lang.IndexOutOfBoundsException:無效指數1,大小爲0
class LoadAllProduct extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(allproduct.this);
pDialog.setMessage("Loading product. Please wait...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
/**
* getting All products from url
* */
protected String doInBackground(String... args) {
Cursor cursor;
int i=0;
while(cursor.moveToNext()){
id_produk[i] = cursor.getInt(0);
String title = cursor.getString(1);
//String price = cursor.getString(2);
//String desc = cursor.getString(3);
//String how_to = cursor.getString(4);
String time = cursor.getString(5);
path_image[i] = cursor.getString(7);
Cursor cur = db.getProductLink(id_produk[i]);
int y = 0;
String link = "";
while(cur.moveToNext()){
if(y == 0) link = cur.getString(0);
else link = link + "\n" + cur.getString(0);
y++;
}
product_item[i] = new MenuItem(title, link, time, path_image[i]);
i++;
cur.close();
}
cursor.close();
db.close();
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String file_url) {
// updating UI from Background Thread
runOnUiThread(new Runnable() {
public void run() {
mainlist.setAdapter(new ListMenuAdapter(product_item));
}
});
pDialog.dismiss();
}
}
列表視圖,現在,我想表明我的產品的詳細只需點擊選擇項目與此代碼
mainlist.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String pid = productList.get(position).get(TAG_PID);
// Starting new intent
Intent in = new Intent(getApplicationContext(),editproductActivity.class);
// sending pid to next activity
in.putExtra(TAG_PID, pid);
in.putExtra("phone", mPhoneNumber);
in.putExtra("daftar", daftar);
startActivityForResult(in, 100);
}
});
}
而這個日誌貓列表視圖顯示此,我認爲錯誤原因字符串PID = productList.get(位置)獲得(TAG_PID);

你能幫我嗎?謝謝
我認爲不是,因爲我可以顯示列表產品,我只是不能顯示產品詳細信息, –
檢查我更新的答案,並將其添加到onItemClick –
yead,你說得對我的尺寸是零:(如何修復它?? –
