安卓：拉伸行TableLayout编程 [英] Android: Stretching rows in TableLayout programmatically

问题描述

我想要动态地创建一个TableLayout有其所有的行像伸展显示的在本教程中。我通过XML来实现它，但我想从活动做到这一点。这里是code我试过到目前为止没有成功：

I'm trying to create a TableLayout dynamically which has all its rows stretched like shown in this tutorial. I've accomplished it via XML, but I'd like to do it from the Activity. Here is the code I've tried so far without success:

public View getTableWithAllRowsStretchedView() {
    LinearLayout linearLayout = new LinearLayout(this);
    linearLayout.setOrientation(LinearLayout.VERTICAL);
    linearLayout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT));

    TableLayout tableLayout = new TableLayout(this);
    tableLayout.setStretchAllColumns(true);
    tableLayout.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.FILL_PARENT));
    tableLayout.setWeightSum(4);


    for (int i = 0; i < 4; i++) {
        TableRow tableRow = new TableRow(this);
        tableRow.setGravity(Gravity.CENTER);
        tableRow.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.FILL_PARENT, 1.0f));

        for (int j = 0; j < 4; j++) {
            Button button = new Button(this);
            final int buttonNumber = (j + i * 4);
            button.setText("" + buttonNumber);
            button.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.FILL_PARENT));

            tableRow.addView(button);
        }
        tableLayout.addView(tableRow);
    }

    linearLayout.addView(tableLayout);
    return linearLayout;
}

非常感谢你提前。

Thank you very much in advance.

推荐答案

您行需要父母的的LayoutParams ：

tableRow.setLayoutParams(new TableLayout.LayoutParams(
                    TableLayout.LayoutParams.FILL_PARENT,
                    TableLayout.LayoutParams.FILL_PARENT, 1.0f));
