點擊通知下載完成它打開下載特定文件夾

Question

的所有文件，在下面的代碼，當下載完成，並於通知用戶點擊即可直接進入文件管理器，打開「我的應用程序」文件夾

在文件夾中的圖像文件，PDF以及excel，word或zip文件在那裏。

文件夾路徑是：/存儲/模擬/ 0 /我的應用

我的代碼是：

ProgressDialog pDialog; public static final int progress_bar_type = 0;所有的

class DownloadFileFromURL extends AsyncTask<String, String, String> { 

    /** 
    * Before starting background thread Show Progress Bar Dialog

     build.setProgress(100, 0, false);

     pDialog = new ProgressDialog(activity); 
     pDialog.setMessage("Downloading file. Please wait..."); 
     pDialog.setIndeterminate(false); 
     pDialog.setMax(100); 
     pDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);

首先，您需要設置將在notification點擊打開一個活動，然後你需要一個ListView顯示在您的ListView所需的文件。

以下代碼可能對您有所幫助。它可以幫助你查看的文件列表視圖和

public void onCreate(Bundle savedInstanceState) 
{ 
super.onCreate(savedInstanceState); 

myList = new ArrayList<String>(); 

String root_sd = Environment.getExternalStorageDirectory().toString(); 
file = new File(root_sd + "/external_sd") ;  
File list[] = file.listFiles(); 

for(int i=0; i< list.length; i++) 
{ 
    myList.add(list[i].getName()); 
} 

setListAdapter(new ArrayAdapter<String>(this, 
     android.R.layout.simple_list_item_1, myList)); 

} 

實現的onClick方法按你的實現你想要做什麼。

我希望它有幫助。
