Question

当我运行我的代码时，它显示9列而不是10.我该如何解决这个问题？

public void maketable() {

    int index = 0;

    isOn = new Boolean[9][10];
    for (int i = 0; i < 9; i++) {
        for (int j = 0; j < 10; j++) {
            isOn[i][j] = true;
        }
    }

    location = new ImageButton[9][10];

    for (int a = 0; a < 9; a++)
    {
        TableRow row = new TableRow(this);
        //TableRow.LayoutParams p = new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT);
        //row.setLayoutParams(p);
        for (int b = 0; b < 10; b++)
        {
            location[a][b] = new ImageButton(this);
            location[a][b].setBackgroundResource(R.drawable.box1);
            location[a][b].setOnClickListener(Onclick);
            location[a][b].setId(index++);

            row.addView(location[a][b]);
        }
        tableLayout.addView(row, a);
    }
}

Answer 1

for (int a = 0; a < 9; a++)仅从0到8。

如果您需要a从0到9（所以有10行），请使用：

for (int a = 0; a < 10; a++)

列数显示为9而不是10
