如何從可充氣的Edit Text中讀取值並將其放入ArrayList中

Question

我經常遇到EditTexts和ArrayLists麻煩，因為我經常使用它們。 我試圖從可膨脹的edittext中獲取輸入的值，並將其放入ArrayList中，但是顯然，我接收到的值始終為0,0,0 。 我怎樣才能解決這個問題？

這是我認為可行的代碼：

public void addCourses() {
    LayoutInflater inflater = LayoutInflater.from(this);
    for (int i = 0; i < this.coursesList.size(); i++) {
        View v = inflater.inflate(R.layout.item_course, null, false);
        this.courses.addView(v);
        final int position = CalculateActivity.this.scoreList.size();
        final int position2 = CalculateActivity.this.totalList.size();
        CalculateActivity.this.scoreList.add(0);

        EditText Score = (EditText) v.findViewById(R.id.Score);
        EditText Total = (EditText) v.findViewById(R.id.Total);

        Score.addTextChangedListener(new TextWatcher() {
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }


            public void afterTextChanged(Editable editable) {
                percentage = Integer.parseInt(editable.toString());
                int perc = (int) percentage;
                CalculateActivity.this.scoreList.set(position, perc);

            }
        });

        Total.addTextChangedListener(new TextWatcher() {
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            public void afterTextChanged(Editable editable) {
                hundredth = Integer.parseInt(editable.toString());
                int hund = (int) percentage;
                CalculateActivity.this.scoreList.set(position2, hund);

            }
        });




    }
}

如果您需要任何其他代碼來幫助您解決此問題，只需將其放在注釋中即可。

編輯：：： ScoreList和TotalList的初始化看起來像這樣

ArrayList<Integer> gradesList = new ArrayList();
ArrayList<Integer> scoreList = new ArrayList();
ArrayList<Integer> totalList = new ArrayList();

另外，上面的代碼在這里使用：

public void onClick(View view) {

        for (int x = 0; x < scoreList.size()&& x < totalList.size(); x++)

        {
            CalculateActivity.this.gradesList.add(scoreList.get(x) / totalList.get(x));

        }



        for (int i = 0; i <  CalculateActivity.this.gradesList.size(); i++) {
             int crdtHrs = ((Course) CalculateActivity.this.coursesList.get(i)).getCreditHours();

                totalCrdtHrs += (int) crdtHrs;
                averageGrade1 += (((int) CalculateActivity.this.gradesList.get(i)) * (((Course) CalculateActivity.this.coursesList.get(i)).getCreditHours()));
                averageGrade2 = averageGrade1/totalCrdtHrs;



        }

        int gpaCalc = averageGrade2;


        CalculateActivity.this.gpa.setText(String.format(""+gpaCalc));
    }
}

還有一個問題是，當我Log.d scoreList或TotalList的ArrayList時，無論我輸入什么值，這些值都將返回0,0,0。

使用getText（）。 這樣會更簡單。

public void onCreate(Bundle savedInstanceState){

super.onCreate(savedInstanceState);
setContentView(R.layout.main);

mButton = (Button)findViewById(R.id.button);
mEdit   = (EditText)findViewById(R.id.edittext);

mButton.setOnClickListener(
    new View.OnClickListener()
    {
        public void onClick(View view)
        {
            Log.v("EditText", mEdit.getText().toString());
        }
    });}
