我已经实现了一个内容提供程序，它导致以下错误

04-25 00:25:16.856：E/AndroidRuntime(520)：原因：android.database.sqlite.SQLiteException：绑定或列索引超出范围：句柄 0x234590

Content Provider 中的查询是

Cursor cursor = qb.query(db, projection, selection, selectionArgs, null, null,
            sortOrder);

并调用 Content Provider 是

cursor = cr.query(uri, new String[] { ContactTableMetaData.ABC,
            ContactTableMetaData.MNP }, ContactTableMetaData.XYZ + "=?",
            new String[] { "phonenumber1", "phonenumber2", "phonenumber3",
                    "phonenumber4", "phonenumber5", "email1", "email2", "email3",
                    "email4", "email5" }, null);

完整的 logcat 是

String selection = ContactTableMetaData.XYZ + "=?";
String[] selectionArgs = new String[] { "phonenumber1", "phonenumber2", "phonenumber3",
                    "phonenumber4", "phonenumber5", "email1", "email2", "email3",
                    "email4", "email5" }

的数量?必须与 的数量相匹配selectionArgs。如果您提供 10 个项目，则selection必须有 10 个?。

中的第 N项被?中selection的第 N 项替换selectionArgs。

编辑：如果你想检查 ContactTableMetaData.XYZ 是否是其中任何一个，那么要么

String selection = ContactTableMetaData.XYZ + "=? OR " + ContactTableMetaData.XYZ + "=? OR " + ...

或者

String selection = ContactTableMetaData.XYZ + " IN (?, ?, ?, ?, ..)"

我更喜欢第二个:)

public static String getWhereStr(String columnName, int selectionArgsSize) {
    String delim = ",";
    final StringBuilder buf = new StringBuilder();
    buf.append(columnName + " IN (");
    for (int i = 0; i < selectionArgsSize; i++) {
        if (i != 0) {
            buf.append(delim);
        }
        buf.append("?");
    }
    buf.append(")");
    return buf.toString(); 
}
