我在 Eclipse 中遇到一个问题:
MainActivity has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@413da0c0 that was originally added here
有人见过这个或者知道如何解决这个问题吗？我已经检查了代码好几次了，但我根本不明白可以采取什么措施来解决它。

最佳答案
您正在抓取一个 ImageView 并尝试在 AsyncTask 的 doInBackground 中操作它。这是禁忌。
此内容以及对它的所有引用不应出现在 doInBackground() 中:
ImageView img = (ImageView) findViewById(R.id.imageView1);
通读Android documentation for AsyncTask并通过谷歌搜索一些示例。
您基本上想要做的是将位图从 doInBackground() 返回到 AsyncTask 的 postExecute() 。然后您可以在那里设置 ImageView 和位图。
为什么 Android AsyncTask 类中有一个 main() ？
