EditTextを動的に追加し、Androidで値を取得することができました。ここからプログラムコードを取得しました（以下のサンプル）

public class Sample extends Activity {
    private List<EditText> editTextList = new ArrayList<EditText>();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        LinearLayout linearLayout = new LinearLayout(this);
        ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(FILL_PARENT, WRAP_CONTENT);
        linearLayout.setLayoutParams(params);
        linearLayout.setOrientation(VERTICAL);

        int count = 10;
        linearLayout.addView(tableLayout(count));
        linearLayout.addView(submitButton());
        setContentView(linearLayout);
    }

    private Button submitButton() {
        Button button = new Button(this);
        button.setHeight(WRAP_CONTENT);
        button.setText("Submit");
        button.setOnClickListener(submitListener);
        return button;
    }

    // Access the value of the EditText

    private View.OnClickListener submitListener = new View.OnClickListener() {
        public void onClick(View view) {
            StringBuilder stringBuilder = new StringBuilder();
            for (EditText editText : editTextList) {
                stringBuilder.append(editText.getText().toString());
            }
        }
    };

    // Using a TableLayout as it provides you with a neat ordering structure

    private TableLayout tableLayout(int count) {
        TableLayout tableLayout = new TableLayout(this);
        tableLayout.setStretchAllColumns(true);
        int noOfRows = count / 5;
        for (int i = 0; i < noOfRows; i++) {
            int rowId = 5 * i;
            tableLayout.addView(createOneFullRow(rowId));
        }
        int individualCells = count % 5;
        tableLayout.addView(createLeftOverCells(individualCells, count));
        return tableLayout;
    }

    private TableRow createLeftOverCells(int individualCells, int count) {
        TableRow tableRow = new TableRow(this);
        tableRow.setPadding(0, 10, 0, 0);
        int rowId = count - individualCells;
        for (int i = 1; i <= individualCells; i++) {
            tableRow.addView(editText(String.valueOf(rowId + i)));
        }
        return tableRow;
    }

    private TableRow createOneFullRow(int rowId) {
        TableRow tableRow = new TableRow(this);
        tableRow.setPadding(0, 10, 0, 0);
        for (int i = 1; i <= 5; i++) {
            tableRow.addView(editText(String.valueOf(rowId + i)));
        }
        return tableRow;
    }     

}

下の図のようにEditTextビューを作成するにはどうすればよいですか？ http://a6.sphotos.ak.fbcdn.net/hphotos-ak-ash4/s720x720/401912_3038335049114_780299491_n.jpg
