,或者當我要把它放到我的代碼的 「onPostExecute」:
if (!_image.isRecycled()) {
_image.recycle();
_image=null;
System.gc();
}
然後我得到:
11-10 13:40:55.117:電子RROR/AndroidRuntime(4981):java.lang.RuntimeException:畫布:試圖使用回收的位圖[email protected]
這是什麼解決方案?
聖地獄這是一團糟。切勿調用System.gc();'。永遠永遠。其次,'handler.post(r);'。耶穌基督這就是asynctask的用途。在onpostexecute中這樣做。 – Falmarri 2010-11-10 19:56:43
