我该如何解决这个java.outOfMemoryError [英] How do I solve this java.outOfMemoryError
本文介绍了我该如何解决这个java.outOfMemoryError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想在listactivity滚动，但延迟非常明显然后崩溃，这是我的customadapter code：
I am trying to scroll in a listactivity but it is laggy then crashes, this is my customadapter code:
public class CustomSearch extends ArrayAdapter<SearchFItem> {
private List<SearchFItem> data;
Context context;
private static class ViewHolder {
ImageView imageView1;
TextView Name;
}
public CustomSearch(Context context, int textViewResourceId,
List<SearchFItem> data) {
super(context, textViewResourceId, data);
this.data = data;
this.context = context;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
SearchFItem item = data.get(position);
ViewHolder holder = null;
View v = convertView;
if (v == null) {
v = LayoutInflater.from(getContext()).inflate(
R.layout.friends_view, null);
holder = new ViewHolder();
holder.imageView1 = (ImageView) v.findViewById(R.id.proView1);
holder.Name = (TextView) v.findViewById(R.id.nameView1);
} else {
holder = new ViewHolder();
holder.imageView1 = (ImageView) v.findViewById(R.id.proView1);
holder.Name = (TextView) v.findViewById(R.id.nameView1);
}
final byte[] encodeByte = Base64.decode(item.getProfPic(),
Base64.DEFAULT);
final Bitmap profpic = BitmapFactory.decodeByteArray(encodeByte, 0,
encodeByte.length);
holder.imageView1.setImageBitmap(profpic);
final String name = item.getName();
holder.Name.setText(name);
return v;
}
}
和这里是我的错误codeS：
and here is my error codes:

感谢您的帮助。我一直停留在这个问题上一段时间。但是这是试图加载的配置文件列表。
Thanks for any help. I have been stuck on this problem a while. But this is trying to load a list of profiles.
推荐答案
如果您有高分辨率的图像，你应该扩展他们下来/根据不同的设备加载图像没有遇到内存故障。
If you have high resolution image , you should scale them down for/depending on different devices to load the image without facing a memory problem.
的在你的情况，有些手机可能不会出现在第一次运行相同的行为，但最终（这是它越来越laggy的部分），不处理优化图像加载的解决方案，应用程序会崩溃的
