android, android-assetmanager, android-assets, assets

Solution

private boolean listAssetFiles(String path) {

    String [] list;
    try {
        list = getAssets().list(path);
        if (list.length > 0) {
            // This is a folder
            for (String file : list) {
                if (!listAssetFiles(path + "/" + file))
                    return false;
                else {
                    // This is a file
                    // TODO: add file name to an array list
                }
            }
        } 
    } catch (IOException e) {
        return false;
    }

    return true; 
}

Call the listAssetFiles with the root folder name of your asset folder.

    listAssetFiles("root_folder_name_in_assets");

If the root folder is the asset folder then call it with

    listAssetFiles("");

Problem

I have some folders with HTML files in the "assets" folder in my Android project. I need to show these HTML files from assets' sub-folders in a list. I already wrote some code about making this list. ``` lv1 = (ListView) findViewById(R.id.listView); // Insert array in ListView // In the next row I need to insert an array of strings of file names // so please, tell me, how to get this array lv1.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, filel)); lv1.setTextFilterEnabled(true); // onclick items in ListView: lv1.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> a, View v, int position, long id) { //Clicked item position String itemname = new Integer(position).toString(); Intent intent = new Intent(); intent.setClass(DrugList.this, Web.class); Bundle b = new Bundle(); //I don't know what it's doing here b.putString("defStrID", itemname); intent.putExtras(b); //start Intent startActivity(intent); } }); ```
