我想顯示一個列表視圖與名稱從我的數據庫中的對話框,但我不斷收到StaleDataException
。我知道這通常意味着我試圖從一個封閉的遊標的數據,但直到我得到的所有數據,所以我不明白爲什麼我收到此StaleDataException與對話框
d = new Dialog(this);
d.setContentView(R.layout.dialog_layout);
d.setTitle("Select Bowler");
ListView lv = (ListView)d.findViewById(R.id.dialog_list);
Cursor c = getContentResolver().query(
BowlersDB.CONTENT_URI,
new String[] {
BowlersDB.ID, BowlersDB.FIRST_NAME, BowlersDB.LAST_NAME
},
null,
null,
BowlersDB.LAST_NAME + " COLLATE LOCALIZED ASC"
);
if (c.moveToFirst() && c != null) {
SimpleCursorAdapter adapter = new SimpleCursorAdapter(
this,
R.layout.names_listview,
c,
new String[] {
BowlersDB.FIRST_NAME, BowlersDB.LAST_NAME
},
new int[] {
R.id.bListTextView, R.id.bListTextView2
},
0
);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
bowlerClickedID = id;
updateName(id);
}
});
d.show();
}
c.close();

光標沒有關閉
編輯: 如果我註釋掉c.close()
行它工作正常,但我不能讓光標打開,但我該怎麼辦?
