android adapter的更新

06-21 12:00:02.473: ERROR/AndroidRuntime(29916): java.lang.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. [in ListView(2131034122, class android.widget.ListView) with Adapter(class android.widget.SimpleAdapter)]

说明了，adapter里面的数据更新(content)不能在在后台，否则会概率性的报错。
可能后台listview adapter会定时看content有否更新。总之

Make sure the content of your adapter is not modified from a background thread, but only from the UI thread.

看过了

if (mItemCount == 0) {                resetList();                invokeOnItemScrollListener();                return;            } else if (mItemCount != mAdapter.getCount()) {                throw new 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. [in ListView(" + getId() + ", " + getClass()                         + ") with Adapter(" + mAdapter.getClass() + ")]");            }

count是创建、更新或者notify时候存的

public void onChanged() {            mDataChanged = true;            mOldItemCount = mItemCount;            mItemCount = getAdapter().getCount();            // Detect the case where a cursor that was previously invalidated has            // been repopulated with new data.            if (AdapterView.this.getAdapter().hasStableIds() && mInstanceState != null                    && mOldItemCount == 0 && mItemCount > 0) {                AdapterView.this.onRestoreInstanceState(mInstanceState);                mInstanceState = null;            } else {                rememberSyncState();            }            checkFocus();            requestLayout();        }

所以渲染之前如果改了adapter的size，那，shi吧
