android文件瀏覽器在網格視圖中列出項目

Question

我想在我的應用中實現文件瀏覽器。我看到了文件瀏覽器的代碼。但在所有這些示例中，dir /文件都列爲lisrview。我想在我的應用程序中提供gridview顯示。文件夾/文件將在網格中列出。點擊文件夾後，它會打開下一級網格。

我沒有看到任何支持這一點的實現。 如果您有任何引用，請分享

感謝時間和支持

添加我的代碼這裏任何人的將來參考

public class FileBrowserActivity extends Activity { 
GridView gridView; 



public static List<FileBrowserItem> gridItemsList; 
public static String name; 
String root; 
String TAG= "FileBrowser"; 
public static boolean multiSelectFlag = false; 
@Override 
public void onCreate(Bundle savedInstanceState) { 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.gridview); 
    root = getIntent().getExtras().getString("rootpath"); 

    Log.i(TAG,"path:"+ root); 

    getGridItemsList(); 
    gridView = (GridView) findViewById(R.id.gridView1); 

    gridView.setAdapter(new FileBrowserGridViewAdapter(this)); 

} 

private void getGridItemsList() { 
    gridItemsList = new ArrayList<FileBrowserItem>(); 
    File file; 
    file = new File(root); 
    File list[] = file.listFiles(); 
    if(list.length == 0){ 
     Toast.makeText(getApplicationContext(), "Empty Folde", Toast.LENGTH_SHORT).show(); 
    } 
    for (int i = 0; i < list.length; i++) { 
     FileBrowserItem item = new FileBrowserItem(); 
     File temp_file = new File(file.getAbsolutePath(),list[i].getName()); 
     item.setPath(file.getAbsolutePath()+"/"+list[i].getName()); 
     item.setName(list[i].getName()); 
     //Log.i(TAG,i + item.value + item.name); 
     if (temp_file.listFiles() != null) { 
      item.setType(FileBrowserItem.DIRECTORY_TYPE) ; 
     } else { 
      item.setType(FileBrowserItem.FILE_TYPE) ; 
     } 
     gridItemsList.add(item); 
    } 

} 
@Override 
public boolean onKeyDown(int keyCode, KeyEvent event) { 
    if ((keyCode == KeyEvent.KEYCODE_BACK)) { 
     root = new File(root).getParent(); 
     Log.i(TAG,"back"+root); 
     getGridItemsList(); 
     finish(); 
     return true; 
    } else { 
     return super.onKeyDown(keyCode, event); 
    } 
} 

}

public View getView(final int position, View convertView, ViewGroup parent) {

       } 
      } 
     }); 
     convertView.setTag(holder); 
    } else { 

     holder = (ViewHolder) convertView.getTag(); 

    } 
    Log.i(TAG, "Position" + position); 
    Log.i(TAG, FileBrowserActivity.gridItemsList.get(position).getName()); 
    holder.text1.setText(FileBrowserActivity.gridItemsList.get(position) 
      .getName()); 
    holder.image 
      .setImageResource(getImageIcon(FileBrowserActivity.gridItemsList 
        .get(position).getType())); 
    if(FileBrowserActivity.multiSelectFlag){ 
     holder.checkBox.setVisibility(View.VISIBLE);
