Question

我试图通过活动创建两个表格布局。我已经有一个表格布局，但如何设置活动？我知道要通过xml来做，但想以编程方式进行..

请帮助

Answer 1

就像在xml中一样，您将创建一个TableLayout，提供参数并添加具有您自己的UI的行。

Answer 2

在xml中使用一个线性布局（或相对布局）通过活动的onCreate（）方法中的findViewById（）获取它的引用。之后动态创建表并将其添加到线性布局。我创建一个方法这样做。前 -

    LinearLayout linear= (LinearLayout ) findViewById(R.id.linear);
    //call method to add the tablelayout.
    linear.addView(createtable(3,5));


 private TableLayout createtable(int requiredcolumn, int requiredrow) {
    TableLayout.LayoutParams tableParams = new TableLayout.LayoutParams(
            TableLayout.LayoutParams.MATCH_PARENT,
            TableLayout.LayoutParams.WRAP_CONTENT, 1f);

    TableLayout.LayoutParams rowParams = new TableLayout.LayoutParams(
            LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT, 1f);
    //for border 
    rowParams.setMargins(2, 2, 2, 2);
    TableRow.LayoutParams itemParams = new TableRow.LayoutParams(
            LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT, 1f);

    TableLayout tableLayout = new TableLayout(MainActivity.this);
    tableLayout.setLayoutParams(tableParams);
    tableLayout.setBackgroundColor(Color.WHITE);

    for (int row = 0; row < requiredrow; row++) {
        TableRow tableRow = new TableRow(MainActivity.this);
        tableRow.setLayoutParams(rowParams);

        for (int column = 0; column < requiredcolumn; column++) {
            Random color = new Random();
            int randomColor = Color.argb(255, color.nextInt(256),
                    color.nextInt(256), color.nextInt(256));

            TextView textView = new TextView(MainActivity.this);
            textView.setLayoutParams(itemParams);
            textView.setBackgroundColor(randomColor);

            tableRow.addView(textView);
        }

        tableLayout.addView(tableRow);
    }

    return tableLayout;
}
