我的內容提供商遇到問題。我在我的一個活動中使用內容提供者，並使用CursorLoader和適配器來顯示列表。net.sqlcipher.database.SQLiteException：綁定或列索引超出範圍：句柄0x7bf058da88
當且僅當我沒有在CursorLoader構造函數中指定selection和selectionArgs參數時，該列表顯示Task表的內容。
我已經嘗試過在選擇和選擇參數的空值，這將返回整個表的內容。我想要做的是選擇基於C_TASK_CALLID列的表的完整投影並傳遞一個callID。
所以我想要做的是一些這樣的SQL返回遊標基地：
select * from table TASK where C_TASK_CALLID = callID;
誰能告訴我爲什麼我收到的folloing錯誤？
我看過以下SO帖子，但它表明選擇和selectionArgs之間存在不匹配。就我而言，這是不正確的，因爲我只傳入一個參數。
。
我得到以下錯誤：

下面是我的任務表：
public static final String C_ID_TASK_QUEST_COMM = BaseColumns._ID;
public static final String C_TASK_QUEST_COMM_QUESTSION = "taskquestcommquestion";
public static final String C_TASK_QUEST_COMM_COMMENTS = "taskquestcommcomments";
public static final String C_TASK_QUEST_ID = "taskquestid";
public static final String C_TASK_QUEST_TYPE = "taskquesttype";
public static final String C_TASK_CALLID = "taskcallid";
public static final String C_TASK_SENT_TO_SERVER = "tasksenttoserver";
public static final String C_TASK_VALUE = "taskvalue";
。下面
是在我的活動我CursorLoader構造：
@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
Log.e(TAG, "inside3 onCreateLoader in ViewCompletedTasksActivityAsync");
String[] projection = { LoginValidate.C_ID_TASK_QUEST_COMM, LoginValidate.C_TASK_QUEST_COMM_QUESTSION, LoginValidate.C_TASK_QUEST_COMM_COMMENTS,

String [] selectionArgs = {callID};
Log.e(TAG, "about to create CursorLoader.....LoginValidate.C_TASK_CALLID = " + LoginValidate.C_TASK_CALLID + " callID = " + callID);
cursorLoader = new CursorLoader(this, RR3ContentProvider.CONTENT_URI_TASKS, projection, LoginValidate.C_TASK_CALLID, selectionArgs , null);
return cursorLoader;
}
。
下面是我的ContentProvider：

你的查詢有incorect WHERE statment - 你正在傳遞selectionArgs但沒有地方綁定它 – Selvin
@Selvin我在這裏找到了解決方案。 https://stackoverflow.com/questions/25754360/how-to-use-selection-args-to-query-specific-rows-from-a-contentprovider-in-andro我認爲CursorLoader構造器抽象了一切，所以我只需要通過選擇和選擇Args。但事實證明，我必須做到以下幾點，並提供佔位符。 cursorLoader = new CursorLoader（this，RR3ContentProvider.CONTENT_URI_TASKS，projection， LoginValidate.C_TASK_CALLID +「=？」，new String [] {callID.trim（）}，null）;無論如何，謝謝 – turtleboy
是的...你shoyld通過'LoginValidate.C_TASK_CALLID +「=？」'那裏 – Selvin
