Android調用系統自帶的文件管理器進行文件選擇

這幾天在做的項目網盤。上傳時需要用到調用系統自帶的文件管理器來選擇文件，後來就在考慮怎麼調用，網上也搜了很久，沒有很好的解決方法，後來在一瞬間發現了一篇不錯的文章，借鑑了一下代碼。

/** 調用文件選擇軟件來選擇文件 **/
private void showFileChooser() {
    intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("*/*");
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    try {
        startActivityForResult(Intent.createChooser(intent, "請選擇一個要上傳的文件"),
                FILE_SELECT_CODE);
    } catch (android.content.ActivityNotFoundException ex) {
        // Potentially direct the user to the Market with a Dialog
        Toast.makeText(getActivity(), "請安裝文件管理器", Toast.LENGTH_SHORT)
                .show();
    }
}

在catch，我們可以做更多的操作，比如會跳轉到一個下載文件管理器的頁面或者等等。

對於返回的數據怎麼處理呢。我項目中的上傳是如下接收

/** 根據返回選擇的文件，來進行上傳操作 **/
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        if (resultCode == Activity.RESULT_OK) {
            // Get the Uri of the selected file
            Uri uri = data.getData();
            String url;
            try {
                url = FFileUtils.getPath(getActivity(), uri);
                Log.i("ht", "url" + url);
                String fileName = url.substring(url.lastIndexOf("/") + 1);
                intent = new Intent(getActivity(), UploadServices.class);
                intent.putExtra("fileName", fileName);
                intent.putExtra("url", url);
                intent.putExtra("type ", "");
                intent.putExtra("fuid", "");
                intent.putExtra("type", "");

                getActivity().startService(intent);

            } catch (URISyntaxException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        super.onActivityResult(requestCode, resultCode, data);
    }
