I have a TextView that displays different text files depending on the user selection from a Spinner. How can I get the name of the text file that is being displayed? The files are in the raw folder.

How do you display your text? If you read the text from the file, then you obviously have access to the file. Hence you can read the filename. – David Medenjak Feb 12 '16 at 17:47

This is the way to obtain the file from raw after being selected in a spinner
Spinner mySpinner=(Spinner) findViewById(R.id.your_spinner);
String rawTextName = = mySpinner.getSelectedItem().toString();
InputStream ins = getResources().openRawResource(
getResources().getIdentifier(rawTextName ,
"raw", getPackageName()));
If you need to read the content this should work
TextView textView =(TextView ) findViewById(R.id.your_textview);
textView.setText = readTextFile(ins);
...
public String readTextFile(InputStream inputStream) {
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
byte buf[] = new byte[1024];
int len;
try {
while ((len = inputStream.read(buf)) != -1) {
outputStream.write(buf, 0, len);
}
outputStream.close();
inputStream.close();
} catch (IOException e) {
}
return outputStream.toString();
}
Hope this helps!!
