java - View 的一个实例上的内存泄漏

Question

我在 ColumnListView 上出现内存泄漏，我将在下面显示泄漏嫌疑点。它占用了已分配内存的 2,720,840 (18.65%) 字节。

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {


    gView = inflater.inflate(R.layout.ac_image_grid, container, false);


    multi = new WeakReference<ColumnListView> ((ColumnListView) (finalView.findViewById(R.id.list)));

One instance of "com.lib.ColumnListView" loaded by "dalvik.system.PathClassLoader @ 0x4123aa30" occupies 2,720,840 (18.65%) bytes. The memory is accumulated in one instance of "byte[]" loaded by "<system class loader>".

Answer 1

这只是一个猜测，但你的转换语法对我来说看起来很奇怪，这也可能导致问题。相反，请尝试:

multi = new WeakReference<ColumnListView> ((ColumnListView)finalView.findViewById(R.id.list));
