我使用Listview / customcursoradapter创建了一个食谱列表。自定义布局包含配方的照片，现在我在查看和滚动ListView时遇到了一些问题，尽管它只有10条记录（目标是150）。有时我会收到此错误java.lang.OutOfMemoryError: bitmap size exceeds VM budget，我已尝试实施AsyncTask，但我没有做到。有什么办法可以解决这个问题吗？
非常感谢您的帮助!!
这是我的getView方法
public View getView(int position, View convertView, ViewGroup parent) {
View row = super.getView(position, convertView, parent);
Cursor cursbbn = getCursor();
if (row == null)
{
LayoutInflater inflater = (LayoutInflater) localContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.listtype, null);
}
String Title = cursbbn.getString(2);
String SandID=cursbbn.getString(1);
String Readyin = cursbbn.getString(4);
String Faovoites=cursbbn.getString(8);
TextView titler=(TextView)row.findViewById(R.id.listmaintitle);
TextView readyinr=(TextView)row.findViewById(R.id.listreadyin);
int colorPos = position % colors.length;
row.setBackgroundColor(colors[colorPos]);
titler.setText(Title);
readyinr.setText(Readyin);
ImageView picture = (ImageView) row.findViewById(R.id.imageView1);
Bitmap bitImg1 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0001);
Bitmap bitImg2 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0002);
Bitmap bitImg3 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0003);
Bitmap bitImg4 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0004);
Bitmap bitImg5 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0005);
Bitmap bitImg6 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0006);
Bitmap bitImg7 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0007);
Bitmap bitImg8 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0008);
Bitmap bitImg9 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0009);
Bitmap bitImg10 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0010);
if(SandID.contentEquals("0001"))
picture.setImageBitmap(getRoundedCornerImage(bitImg1));
if(SandID.contentEquals("0002"))
picture.setImageBitmap(getRoundedCornerImage(bitImg2));
if(SandID.contentEquals("0003"))
picture.setImageBitmap(getRoundedCornerImage(bitImg3));
if(SandID.contentEquals("0004"))
picture.setImageBitmap(getRoundedCornerImage(bitImg4));
if(SandID.contentEquals("0005"))
picture.setImageBitmap(getRoundedCornerImage(bitImg5));
if(SandID.contentEquals("0006"))
picture.setImageBitmap(getRoundedCornerImage(bitImg6));
if(SandID.contentEquals("0007"))
picture.setImageBitmap(getRoundedCornerImage(bitImg7));
if(SandID.contentEquals("0008"))
picture.setImageBitmap(getRoundedCornerImage(bitImg8));
if(SandID.contentEquals("0009"))
picture.setImageBitmap(getRoundedCornerImage(bitImg9));
if(SandID.contentEquals("0010"))
picture.setImageBitmap(getRoundedCornerImage(bitImg10));
return row;
}
这是错误：

答案 0 :(得分：3)
首先，你没有使用convertView，你应该这样开始，
View view = convertView;
if (view == null) {
// inflate
}
这是一篇关于使用convertView的博客文章，
http://android-er.blogspot.com/2010/06/using-convertview-in-getview-to-make.html
其次，您应该只解码您将使用的位图。所以改变你的方法，
if(SandID.contentEquals("0001"))
Bitmap bitImg1 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0001);
picture.setImageBitmap(getRoundedCornerImage(bitImg1));
...
第三，你可以解码一次，并在这种方法之外使用吗？例如，在构造函数中对它们进行一次解码，并将它们作为实例成员存储在适配器类中，然后在getView()中使用它们。
第四，你在回收你的位图吗？位图的分配方式与其他对象的分配方式不同，并且在完成使用后需要调用它们的recycle()方法。如果你可以实现上面的第三项，你可以在大多数情况下避免这种复杂性，虽然你应该在你的活动停止时释放它们，在它们开始时重新分配它们。
关于Bitmap.recycle()的SO有很多很好的信息，我建议你花点时间研究它。解释错综复杂的内容超出了这里的帖子所能完成的内容。这是一篇很好的SO帖子，涵盖了这个主题，
Bitmap, Bitmap.recycle(), WeakReferences, and Garbage Collection
