If you want to find all the files in the top folder of the SDCard you can do something like this:

public GetFileNames(Context context) {
    File dir = Environment.getExternalStorageDirectory();

    ArrayList<String> fileNames = new ArrayList<String>();
    for (File f : dir.listFiles()) {
        if (f.isFile()){
            name = f.getName();
            fileNames.add(name);
        }
    }
    //Do whatever you want with fileNames array. 
}

EDIT: If you want to get your apps private filenames you should do this:

public GetFileNames(Context context) {
    File dir = context.getFilesDir();

    ArrayList<String> fileNames = new ArrayList<String>();
    for (File f : dir.listFiles()) {
        if (f.isFile()){
            name = f.getName();
            fileNames.add(name);
        }
    }
    //Do whatever you want with fileNames array. 
}
