Get filenames from a directory in Android

Question

I want to populate a spinner with the filenames of files found on the SD card with specific extensions. I can get it thus far to populate the spinner with the correct files,

Answer 1

File filePath= new File(File Address);
File[] fileList = filePath.listFiles();
String name = fileList [0].getName().toString();

Answer 2

File sdCardRoot = Environment.getExternalStorageDirectory();
File yourDir = new File(sdCardRoot, "path");
for (File f : yourDir.listFiles()) {
    if (f.isFile())
        String name = f.getName();
        // Do your stuff
}

Have a look at Environment page for more info.

Answer 3

Try below code

File sdCard = Environment.getExternalStorageDirectory();
File dir = new File(sdCard, "yourpath");
for (File f : dir.listFiles()) {
    if (f.isFile())
        String name = f.getName();
        // do whatever you want with filename
}

Answer 4

could you process the string in reverse order(right to left), finding the first slash, then cutting the string at that point and taking the rightmost part of the string as the filename ?

Answer 5

use method getName() of file object:

file.getName();

Answer 6

Above answers are giving null pointer exception in my case. Following code worked for me:

File yourDir = new File(Environment.getExternalStorageDirectory().getPath() + "/WhatsApp/Databases");
    for (File f : yourDir.listFiles()) {
        if (f.isFile())
            name = f.getName();
        // Do your stuff
}
