如何在android代码中动态设置layout_span、layout_margin

Answer 1

您可以使用TableRow.LayoutParams 实例设置 layout_margin 给TableRow.addView()：

TableLayout newTable = new TableLayout(DisplayContext);
int rowIndex = 0;

// First Row (3 buttons)
TableRow newRow1 = new TableRow(DisplayContext);
newRow1.addView(new Button(DisplayContext), 0);
newRow1.addView(new Button(DisplayContext), 1);
newRow1.addView(new Button(DisplayContext), 2);
newTable.addView(newRow1, rowIndex++);

// Second Row (2 buttons, last one spans 2 columns)
TableRow newRow2 = new TableRow(DisplayContext);
newRow2.addView(new Button(DisplayContext), 0);
Button newButton = new Button(DisplayContext);

// Create the layout to span two columns
TableRow.LayoutParams params = new TableRow.LayoutParams();
params.span = 2;
newRow2.addView(newButton, 1, params);

newTable.addView(newRow2, rowIndex++);
