IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes. [in ListView(xxxxx, class android.widget.ListView) with Adapter

因为需要加载数据较多，构建数据需要较长时间，如果放在主线获取数据源，会导致UI卡顿
遂采用第二种方案，获取数据放在子线程，更新数据时采用clone的方式保证Adapter的数据源完全由Adapter自身维护
public abstract class EventAdapter<T> extends BaseAdapter {
protected ArrayList<T> mData;
protected Context mContext;
public EventAdapter(Context context) {
this.mContext = context;
}
/**
* <p>
* 使用 ArrayList.clone()保证Adapter里的数据完全是由adapter维护。
* </p>
* 这样就可以先在子线程中加载数据，在UI线程中调用该方法刷新界面，保证UI的流畅性。

public void setData(ArrayList<T> dataList) {
if (dataList != null) {
this.mData = (ArrayList<T>) dataList.clone();
notifyDataSetChanged();
}
}
public ArrayList<T> getData() {
return mData;
}
@Override
public int getCount() {
return mData != null ? mData.size() : 0;
}
@Override
public Object getItem(int position) {
return mData.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
}
