請幫助我解決此問題。在這裏，我粘貼我的代碼：Android中使用OnClickItemListener時出現OutOfMemoryError
我已經嘗試過，但無法找出我失蹤的東西。我使用兩個片段兩個顯示列表。現在我想在用戶單擊第一個列表項時更改第二個片段中的列表數據。默認情況下，將選擇零位索引來顯示第二個列表中的數據。我正在使用自定義數組適配器來顯示這兩個片段中的列表。請幫助我們。感謝您的考慮。在這裏，我貼我的代碼，我正在此錯誤：
完整代碼：onItemClickListener between two fragments

這是我的位地圖代碼：
try {
System.out.printf("src", src);
URL url = new URL(src);
HttpURLConnection connection = (HttpURLConnection) url
.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
Bitmap myBitmap = BitmapFactory.decodeStream(input);
System.out.printf("Bitmap", "returned");
return myBitmap;
} catch (IOException e) {
e.printStackTrace();
System.out.printf("Exception", e.getMessage());
return null;
}
請向我們展示logcat（我會在進一步的請求pslc中縮短它） –
請檢查我已粘貼 – rup35h
您的圖片太大。在StackOverflow上有很多答案，可以幫助您在加載時縮小它們的大小。 – Simon
