如何在TableView中均匀分布元素

Question

我试图使桌子上装满按钮，然后将按钮均匀地分布在桌子上。但是，当我这样做时，按钮不会显示完整的高度，看起来像这样：https://imgur.com/a/L3c5Yrk

这是我用于创建表的代码。我已经手动创建了表格视图，但是必须以编程方式创建按钮和表格行。

/* Find Tablelayout defined in main.xml */
    TableLayout tl = findViewById(R.id.gameBoard);
    /* Create a new row to be added. */
    for (int j = 0; j < 3; j++) {
        TableRow tr = new TableRow(this);
        tr.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
        /* Create a Button to be the row-content. */
        for (int i = 0; i < 3; i++) {
            final Button b = new Button(this);
            b.post(new Runnable() {
                @Override
                public void run() {
                    TableLayout myTableLayout = findViewById(R.id.gameBoard);
                    int width = myTableLayout.getWidth();
                    int height = myTableLayout.getHeight();

                    ViewGroup.LayoutParams params = b.getLayoutParams();
                    params.height = (height - (10 * 4))/3;
                    params.width = (width - (10 * 4))/3;
                    b.setLayoutParams(params);

                }
            });
            b.setText("Dynamic Button");
            b.setBackgroundColor(Color.parseColor("#FFFFFF"));
            float px = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 10, getResources().getDisplayMetrics());
            float xPixel = px * (1 + i);
            float yPixel = px * (1 + j);
            b.setX(xPixel);
            b.setY(yPixel);
            b.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {
                    flip(v);
                }
            });

            b.setId(i + (j * 3));

            buttons.add(b);

            /* Add Button to row. */
            tr.addView(b);
        }
        /* Add row to TableLayout. */
//tr.setBackgroundResource(R.drawable.sf_gradient_03);
            tl.addView(tr, new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.WRAP_CONTENT));
        }
