Android模擬器ImageView崩潰

Question

我添加了ImageView並分配了一個jpg文件（a1.jpg），該文件是770Kb。當我運行該項目時，會崩潰並顯示很多錯誤日誌。我已經嘗試另一個JPG文件，大小爲70KB並運行該項目，這成爲沒有問題。爲什麼？謝謝！

<ImageView 
    android:id="@+id/imageView1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentTop="true" 
    android:layout_centerHorizontal="true" 
    android:contentDescription="@string/Test_string" 
    android:src="@drawable/a1" /> 

錯誤日誌

Answer 1

這可能是因爲你試圖加載太大的文件。即使你的錯誤這樣說：

Caused by: java.lang.OutOfMemoryError 

770KB對於android應用程序的圖像是相當大的。你應該考慮更小的東西。

您還可以在AVD中增加模擬器的堆大小，但在您的情況下，如果可以，最好使用較小的圖像。

Answer 2

嗯...這聽起來像你繪製的設置可能不正確。你確定名字等嗎？

Answer 3

模擬器無法支持那麼大的圖像，如java.lang.OutOfMemoryError所示。您應該能夠通過進入AVD管理器來自定義模擬器以允許更大的內存（我相信這是最大的VM應用程序堆大小）。

Answer 4

我有同樣的問題，並且Piotr Chojnacki是對的;這是一個圖像尺寸問題。我認爲這對老設備和模擬器來說更是一個問題。
