推荐答案

我用同样的源代码中我的应用程序（pretty的肯定），且有code块：

I used the same source in my app (pretty sure), and there is a block of code:

protected void onListItemClick(ListView l, View v, int position, long id) {
    if (file.isDirectory()) {
        selectButton.setEnabled(false);
        if (file.canRead()) {
            lastPositions.put(currentPath, position);
            getDir(path.get(position));
        } else {
            new AlertDialog.Builder(this)
                    .setIcon(R.drawable.icon)
                    .setTitle(
                            "[" + file.getName() + "] "
                                    + getText(R.string.cant_read_folder))
                    .setPositiveButton("OK",
                            new DialogInterface.OnClickListener() {

                                @Override
                                public void onClick(DialogInterface dialog,
                                        int which) {

                                }
                            }).show();
        }
    } else {
        selectedFile = file;
        v.setSelected(true);
        selectButton.setEnabled(true);
    }
}

您只需要编辑它如何处理的如果（file.isDirectory（））。我会建议声明布尔的价值在你的活动，你更改为真如果该文件是一个目录，它是已经假的。那么，如果说价值是真实的，然后遍历目录。此外，当您更改表示值真，你就需要调用 selectButton.setEnabled（真）。这将是相当多的不是使自己的code那么复杂，我会说。

You just have to edit how it handle's if (file.isDirectory()). I would recommend declaring a boolean value in your Activity which you change to true if the file is a directory and it is already false. Then if said value is true, then traverse the directory. Also when you change said value to true, you would need to call selectButton.setEnabled(true). This would be quite a bit less complicated than making your own code, I would say.
