帮助了解是否存在内存泄漏。
分段
public class NewsFragment extends Fragment {
//some code
private OnNewsFeedsContentClickListener onNewsFeedsContentClickListener = new OnNewsFeedsContentClickListener()
{
@Override
public void onClick(String sYoutubeId, ContentType type)
{
//some code
}
}
}
适配器
public class HowToAdapter extends BaseAdapter {
public static final String TAG = "HowToAdapter";
private List<ContentSkill> mContentList = null;
private Context mContext = null;
private ImageLoader mImageLoader = null;
private OnNewsFeedsContentClickListener mOnNewsFeedsContentClickListener = null;
public HowToAdapter(Context context, List<ContentSkill> contetnList, OnNewsFeedsContentClickListener onNewsFeedsContentClickListener)
{
mContext = context;
mContentList = contetnList;
mImageLoader = new ImageLoader(mContext, ImageType.HOW_TO);
mOnNewsFeedsContentClickListener = onNewsFeedsContentClickListener;
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
HowToView view = null;
if (convertView == null)
{
view = new HowToView(mContext);
}
else
{
view = (HowToView) convertView;
}
ContentSkill content = getItem(position);
if (content != null)
{
ViewHolder holder = (ViewHolder) view.getTag();
final String url = Utils.getYouTubeUrlImageFromUrl(content.getUrl());
final String youtubeId = Utils.getYoutubeIdFromUrl(content.getUrl());
mImageLoader.displayImage(url, holder.pIvThumb);
holder.pIvThumb.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
mOnNewsFeedsContentClickListener.onClick(youtubeId, ContentType.VIDEO);
}
});
}
return view;
}
问题
:
_
- 适配器变量final String youtubeId总是会被创建,但不会被杀死?也就是说,每次都会创建 getView() 但旧的youtubeId无法从内存中清除?
- 每次调用getView() OnClickListener 也会被创建,老的会被清理出内存?
我认为每次都会重新创建变量并赶上旧内存。
