我知道这个问题经常被问到,但这个问题完全不同。日志文件只是多次发布上述异常而没有提及原因。日志文件如下所示

请帮忙。我无法弄清楚问题所在

我认为问题是由于这一行 icon.recycle();,因为recycle()方法是释放与位图关联的本机对象,并清除对像素数据的引用。所以尝试像这样使用

 states.addState(new int[] { android.R.attr.state_selected }, new BitmapDrawable(res, selected));
        states.addState(new int[] { android.R.attr.state_enabled }, new BitmapDrawable(res, unselected));
        icon.recycle();
