ListView 出现 OutOfMemory 错误，我尝试垃圾收集但失败

【问题标题】：OutOfMemory Error at ListView, I try to garbage Collect but failedListView 出现 OutOfMemory 错误，我尝试垃圾收集但失败
【发布时间】：2014-05-12 20:35:19
【问题描述】：

从我的 ListView 创建新 Activity 时出现 OutOfMemory 错误。我在 Picasso Library 的 listview 中加载图像。

这是由很多位图图像造成的 OutOfMemory 错误吗？

我尝试垃圾收集图像，但我认为它不起作用。

在 Question.java

// this java file return view to adapter at adapter's getView()

public View getView(LayoutInflater inflater, View convertView, int mPosition, NewsFeedListViewAdapter newsFeedListViewAdapter, final Context mContext) 
{



    try
    {
                 /**get view in here**/

    }
    catch (OutOfMemoryError e) 
    {

        newsFeedListViewAdapter.recycleHalf();
        System.gc();
        return getView( inflater, convertView,  mPosition,  newsFeedListViewAdapter,  mContext) ;
    }

    newsFeedListViewAdapter.addRecycleList(
            new WeakReference<View>(
                    newsFeedQuestionViewHolder.imageview_profile_image));







    return convertView;
}

在 NewsFeedListViewAdapter.java

public void recycleHalf() 
{
    int halfSize = mRecycleList.size() / 2;
    List<WeakReference<View>> recycleHalfList = mRecycleList.subList(0, halfSize);
    RecycleUtils.recursiveRecycle(recycleHalfList);

    for (int i = 0; i < halfSize; i++)
        mRecycleList.remove(0);
}


public void recycle() 
{
    RecycleUtils.recursiveRecycle(mRecycleList);
}

public void addRecycleList(WeakReference<View> view)
{
    mRecycleList.add(view);
}

【问题讨论】：

  • 也许您可以按照此处的建议通过解码位图来减少所需的内存量：developer.android.com/training/displaying-bitmaps/load-bitmap.html
  • @MarkW 我只是为了便于查看而删除了它...
  • 如果出现 OOM 错误，System.gc() 不是解决方案。

标签： java android garbage-collection out-of-memory


【解决方案1】：

尝试减小图像的大小，我认为这是第一个问题。

05-13 05:15:41.666: D/skia(19437): --- allocation failed for scaled bitmap

【讨论】：

    【解决方案2】：

    您正在尝试加载 12Mb 的图像，这可能太大而无法放入内存。

    如果您不需要图像的完整定义，您可以使用BitmapFactory 和BitmapFactory.Options inSampleSize 来缩放位图在加载到内存之前。

    您可以在官方文档中获取更多信息：Loading Large Bitmaps Efficiently

    【讨论】：

    • 我用毕加索图书馆的时候可以用吗？？
    • 如果我没记错的话，Picasso 库提供了一个 resize() 方法，它应该为您处理大小调整。您只需要计算尺寸（例如屏幕的宽度，以及相应的高度）
