这整个内存泄漏的事情对我来说似乎很复杂。这里有很多很棒的信息，但我不太明白。即使在阅读了用 Java 创建内存泄漏之后，我仍然迷路了！有人可以向我指出这段代码中的内存泄漏在哪里吗？（重复运行此方法时会发生这种情况。）非常感谢！

在 java 中，内存使用过多的常见原因是对象在某种循环中被分配而不是被销毁，例如游戏循环。您是否在循环中添加到动态数组/排序列表？此外，如果一个方法需要一段时间，这种影响可能会在局部变量被销毁之前发生。

ImageView如果您经常更改他们的图像，您需要这样做

可绘制对象 = imgView.getDrawable();

if( obj instanceof BitmapDrawable)
{
    Bitmap bmp = obj.getBitmap();
    bmp.Recycle();
}

在此语句之前调用 cleanupcode 函数

Bitmap CleanupCode(ImageView imgView) {

Drawable obj = imgView.getDrawable(); 

if( obj instanceof BitmapDrawable) {

 Bitmap bmp = obj.getBitmap(); bmp.Recycle(); return bmp;
 }
 return null; 
} 
////

Bitmap bmp = CleanupCode(c); 

c.setImageResource(R.drawable.clubs3); 
if(null != bmp) {
bmp.Recycle(); 
bmp = null; 
}
