如何在Android中顯示從SD卡的DOC文件列表？

Question

如何在單擊Android中的按鈕後顯示doc文件，以及如何通過單擊Android打開該文檔的該文檔？

是否可以在不使用應用程序的情況下顯示文檔。

Answer 1

這將幫助你的SD卡/目錄內的所有.doc文件添加到ArrayList中 後來才填充這個數據到ListView控件或任何你想

 ArrayList<String> wordFiles = new ArrayList<String>(); 
     String currentFile; 
     String path = "dir//"; 
     File sd = Environment.getExternalStorageDirectory(); 
     File folder = new File(sd,path); 
     File[] listOfFiles = folder.listFiles(); 
     for (int i = 0; listOfFiles!=null &&i< listOfFiles.length; i++) 
     { 

      if (listOfFiles[i].isFile()) 
      { 
       currentFile = listOfFiles[i].getName(); 
       if (currentFile .endsWith(".doc")) 
       { 
        //currentFile =currentFile.replace(".doc", ""); 
        wordFiles .add(currentFile); 

       } 
      } 
     } 

以及用於打開.DOC（用戶必須有一個可以處理.docs文件的應用程序） 試試這個：

File sd = Environment.getExternalStorageDirectory(); 
    File file = new File(sd, "dir//file.doc"); 
    Intent intent = new Intent(); 
    String type = "application/msword"; 
    intent.setDataAndType(Uri.fromFile(file), type); 
    startActivity(intent);

在這裏，我曾與遞歸文件列表嘗試，從SD卡和SD卡innerfolder的列出所有的Word文件。可能會對你有用。
