从EditText添加到ArrayList

Question

I am trying to implement a button that saves integers entered into an EditText and save them into an ArrayList . I declared my ArrayList globally in my class and am calling it inside of my OnClickListener method. I am unsure whether or not I am saving to this ArrayList because I am unable to display what I have saved in said ArrayList .

My declaration of the list is;

ArrayList<String> savedScores = new ArrayList<String >();

This is what I am using to save to my ArrayList ;

`savedScores.add(input1.getText().toString());`

Now, in my OnClickListener method, I have a button that saves user input into the ArrayList (or so I am hoping), and another to display what I have saved. However, when I click on the "editScore" button, the TextEdit is cleared as if I have nothing saved in my ArrayList . This is simply a test to see if I am properly saving to my array and any help would be much appreciated! Thank you.

switch (view.getId()) {
            case R.id.buttTotal:
                if (blankCheck.equals("")) {
                    Toast blankError = Toast.makeText(getApplicationContext(), "YOU CANT SKIP HOLES JERK", Toast.LENGTH_LONG);
                    blankError.show();
                    break;
                } else {
                    int num1 = Integer.parseInt(input1.getText().toString()); //Get input from text box
                    int sum = num1 + score2;
                    score2 = sum;
                    output1.setText("Your score is : " + Integer.toString(sum));
                    input1.setText(""); //Clear input text box

                    //SAVE TO THE ARRAYLIST HERE
                    savedScores.add(input1.getText().toString());
                    break;
                }
            case R.id.allScores: //CHANGE THIS TO AN EDIT BUTTON, ADD A HOLE NUMBER COUNTER AT TOP OF SCREEN!!!!!
                output1.setText("you messed up");
                break;
            case R.id.editScore: //Need to set up Save Array before we can edit
                output1.setText(savedScores.get(0));
                break;
        }

Answer 1

Because you are saving empty values into your ArrayList . See here

 input1.setText(""); //Clear input text box

 //SAVE TO THE ARRAYLIST HERE
 savedScores.add(input1.getText().toString());

The value of input1 is empty. Clear the input after you saved it to the array.
