java.io.FileNotFoundException:

[英]java.io.FileNotFoundException:

由於別人離開公司,我目前正在研究其他人的項目。 我只是在實習,而Java不是我的強項。

基本上,該應用程序從接收到提要中的信息開始工作,並將該信息放置在相關位置。

但是,客戶要求在同意的圖像上放置圖形。

這對我來說已經完成了,因為我無法訪問該供稿。

我想指出的是,帶有圖形的提要在iPhone應用程序上運行良好。

按下搜索按鈕后,此消息會在我的日志目錄中輸出:java.io.FileNotFoundException: http : //images.ultrait.me/ImageProcessor.aspx? imageURL=381/Sales/321470/53659_T_ADDRESSES_52050_TN.jpg&Text=LET AGREED

從單擊鏈接可以看到,出現了圖標。

當我單擊選項卡以搜索屬性時,提要將開始加載,並且圖像將出現在列表視圖中。 圖片會出現,但是上面沒有讓我們同意的圖標,我相信是因為它是將Feed中的一張圖片作為縮略圖放置,但是我需要它來顯示圖形(我不確定這是否甚至是正確的)。

當我單擊查看屬性時,圖像消失。

我正在工作到最后期限,沒有人幫我。 請耐心等待我。

這是我認為您可能需要看的一些我的課。

我沒有檢查您的代碼,但是我想到的第一件事是:您檢查了應用程序的權限嗎? 它可能來自那里。 (例如:沒有互聯網許可,找不到文件,因為它沒有訪問權限)

編輯:您應該檢查(調試或登錄)此“ str_imageURLs [i]”是否未返回奇怪的內容(並且應該刪除URL中的空格)。

然后,如果有問題,我想它來自於此:“ FindPropertyActivity.DownloadImage”您能張貼它嗎? 您是否將圖像作為輸入流並從中形成可繪制對象(如果不是在DownloadImage中完成的操作)?

Edit2 :我創建了一個基本應用程序,在布局中僅包含一個ImageView。 然后,我使用您的“ DownloadImage”方法從網址中獲取了沒有附加參數的圖片(我在“ .jg”處停止了)。 它在android 4.2上不起作用,因為它要求它是異步的。

我在主要活動中添加了它,然后它起作用了:

ThreadPolicy tp = ThreadPolicy.LAX;
StrictMode.setThreadPolicy(tp);

但是顯然,這不是要做的事情。

問題不在於您的URL或獲取圖像的方法。 它與android 4.2正常工作。

您能用Log.e(“ PutClassNameHere”,“將您的自定義消息放在這里”,可拋出)替換所有的system.out.println ***嗎? 這將在您的logCat中寫入錯誤
