如何正确清除 ImageView?

How to clear ImageView correctly?(如何正确清除 ImageView?)

问题描述

例如，在我的活动中，我有这样的代码(我跳过了变量的初始化):

For example, in my Activity I have such code (I skip the initialization of variables):

ImageView iview; //some ImageView
Bitmap b; //some Bitmap
iview.setImageBitmap(b);

问题是 - 如何正确清除 iview 资源(无论是否破坏视图)?ImageView 会在 b.recycle() 之后释放它的资源(在本机代码中使用)吗?

Question is - how to clear iview resources correctly (with or without destroying view) ? Would ImageView free it's resources (used in native code) after b.recycle()?

我想，ImageView 不只是在 Activity onStop(或 onDestroy)之后释放它的资源.

I suppose, that ImageView doesn't just free it resources after Activity onStop (or onDestroy).

推荐答案

imgview.setImageResource(0);

或

imgview.setImageDrawable(null);
