<pre name="code" class="java">关键函数：
    511    private void startLoadingDirectoryPartition(int partitionIndex) {
    512        DirectoryPartition partition = (DirectoryPartition)mAdapter.getPartition(partitionIndex);
    513        partition.setStatus(DirectoryPartition.STATUS_LOADING);
    514        long directoryId = partition.getDirectoryId();
    515        if (mForceLoad) {
                  //一直调用if语句，没有调用else，应该调用else就可以利用<pre name="code" class="java">                延时读取队列来修复
    516            if (directoryId == Directory.DEFAULT) {
    517                loadDirectoryPartition(partitionIndex, partition);
    518            } else {
    519                loadDirectoryPartitionDelayed(partitionIndex, partition);
    520            }
    521        } else {
    522            Bundle args = new Bundle();
    523            args.putLong(DIRECTORY_ID_ARG_KEY, directoryId);
    524            getLoaderManager().initLoader(partitionIndex, args, this);
    525        }
    526    }

逻辑调用：  
private static final int DIRECTORY\_SEARCH\_MESSAGE = 1; private void loadDirectoryPartitionDelayed(int partitionIndex, DirectoryPartition partition) \{ mDelayedDirectorySearchHandler.removeMessages(DIRECTORY\_SEARCH\_MESSAGE, partition); Message msg = mDelayedDirectorySearchHandler.obtainMessage( DIRECTORY\_SEARCH\_MESSAGE, partitionIndex, 0, partition); mDelayedDirectorySearchHandler.sendMessageDelayed(msg, DIRECTORY\_SEARCH\_DELAY\_MILLIS); \} private Handler mDelayedDirectorySearchHandler = new Handler() \{ @Override public void handleMessage(Message msg) \{ if (msg.what == DIRECTORY\_SEARCH\_MESSAGE) \{ loadDirectoryPartition(msg.arg1, (DirectoryPartition) msg.obj); \} \} \};
