如何消除這個錯誤 (android.content.res.Resources$NotFoundException: String resource ID #0xffffffff)

Question

我正在構建一個包含 SQLite DB 的 Android 應用程序，我在翻譯 SQLite 保存的數據時遇到了問題，然后我找到了一個解決方案，它是一種獲取字符串資源 ID 的方法，並且運行良好，然后該應用程序運行良好突然這個錯誤顯示我不知道為什么，請幫忙

我用來獲取字符串資源的方法：

     public static int getResId(String resName, Class<?> c) {

        try {
            Field idField = c.getDeclaredField(resName);
            return idField.getInt(idField);
        } catch (Exception e) {
            e.printStackTrace();
            return -1;
        }
    }

適配器中的代碼

    textViewname.setText(context.getString(R.string.product_Name)+" " + repo.getName());
    textViewquantity.setText(context.getString(R.string.last_added_qty)+" " + repo.getQuantity() + " " + context.getResources().getString(mdatabase.getResId(repo.getItemsType(),R.string.class)));

    textViewOutputqty.setText(context.getString(R.string.last_out_qty)+" " + repo.getOutputqty() + " " + context.getResources().getString(mdatabase.getResId(repo.getItemsType(),R.string.class)));

    textViewProfitSIngle.setText(context.getString(R.string.retail_profit)+" " + repo.getProfitSingle() + " " + context.getResources().getString(mdatabase.getResId(repo.getCurrency(),R.string.class)));
    textViewProfitMultiple.setText(context.getString(R.string.wholesale_profit)+" " + repo.getProfitMultiple() + " " + context.getResources().getString(mdatabase.getResId(repo.getCurrency(),R.string.class)));
    textViewPurchasingPrice.setText(context.getString(R.string.purchasing_price)+" " + repo.getPurchasingPricePeranItem() + " " + context.getResources().getString(mdatabase.getResId(repo.getCurrency(),R.string.class)));
    textViewTotalPurchasingPrice.setText(context.getString(R.string.total_purchase_price)+" " + repo.getTotalPurchasingPrice() + " " + context.getResources().getString(mdatabase.getResId(repo.getCurrency(),R.string.class)));

    textViewtotalItemsInBoexs.setText(context.getString(R.string.total_units)+" "+ repo.getTotalitemsInboxes() +" "+ context.getResources().getString(R.string.Pieces));

Answer 1

發生此錯誤是因為您試圖獲取不存在的資源。 這是因為您存儲了分配給字符串資源的內存地址，並且下次可能會更改。 我不知道你的場景是什么，但為什么你已經將它存儲在你的字符串中，它永遠不會丟失。 只有當您說出您要實現的目標時，我才能幫助您構建另一個邏輯。
