从资产文件夹获取txt文件的名称到列表中

Question

I'm trying to get a list of the name of txt files stored in my assets folder but when i call

String[] files = assetManager.list("/assets");

i get an exception

01-13 15:48:44.819: E/AndroidRuntime(6754): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.readd/com.example.readd.MainActivity}: 

i suppose i have and error with the parameter "/assets" in list("/assets")., but dont have idea how to solve it.

EDIT in my assets folder i got just raw files without subfolders

text1.txt

text2.txt

text3.txt

i've try also assetManager.list(""); but when i try to set a txtView with the name of the(lets say) first file tt.setText(files[0]);, it give's me images as a result, and i dont have file like that in my assets

EDIT2

            AssetManager assetManager = getApplicationContext().getAssets();
    try {

        String[] files = assetManager.list("");

        InputStream stream = getAssets().open("text1.txt");

        tt.setText(files[0]);//here i get images(as String not real images) as result
        }

Answer 1

it should be

String[] files = assetManager.list("");

if you want to get what's inside a subfolder pass the name of the subfolder:

String[] files = assetManager.list("mySubFolder");
