I have a button which stores data written in the EditText form above it

  • 0

I have a button which stores data written in the EditText form above it to internal memory, but for some reason the code doesn’t work. It doesn’t even display the toast message.

final Button save = (Button) findViewById(R.id.buttonSave);
final String Day = dayName;

save.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                String FILEOUTPUT = Day;
                BufferedWriter bfw;

                try {
                    bfw = new BufferedWriter (new FileWriter(FILEOUTPUT));
                    Scanner scan = new Scanner(new File(editData.getText().toString()));

                    bfw.write(scan.nextLine());
                    bfw.close();
                    Toast.makeText(ModifyInfo.this, "Saved", Toast.LENGTH_SHORT);
                } catch (Exception e) {
                    Toast.makeText(ModifyInfo.this, "Save error", Toast.LENGTH_SHORT);  
                }
            }
        });

    what you doing with this line is wrong probably editData.getText().toString().If your editData is an EditText then your program will need a file name from it.I think you are not providing file name here.You are supposed to enter the string here that should be saved in the file.
