GridLayout的列跨度在Xamarin.android中不起作用

// 创建GridLayout布局
GridLayout gridLayout = new GridLayout(this);
gridLayout.RowCount = 2;
gridLayout.ColumnCount = 3;

// 创建视图
TextView textView1 = new TextView(this);
textView1.Text = "View 1";

TextView textView2 = new TextView(this);
textView2.Text = "View 2";

TextView textView3 = new TextView(this);
textView3.Text = "View 3";

// 设置视图的布局参数
GridLayout.LayoutParams layoutParams1 = new GridLayout.LayoutParams();
layoutParams1.ColumnSpec = GridLayout.InvokeSpec(0, 2); // 设置列跨度为2
textView1.LayoutParameters = layoutParams1;

GridLayout.LayoutParams layoutParams2 = new GridLayout.LayoutParams();
layoutParams2.ColumnSpec = GridLayout.InvokeSpec(2); // 设置列跨度为1
textView2.LayoutParameters = layoutParams2;

GridLayout.LayoutParams layoutParams3 = new GridLayout.LayoutParams();
layoutParams3.ColumnSpec = GridLayout.InvokeSpec(0); // 设置列跨度为1
textView3.LayoutParameters = layoutParams3;

// 将视图添加到GridLayout布局中
gridLayout.AddView(textView1);
gridLayout.AddView(textView2);
gridLayout.AddView(textView3);

// 将GridLayout布局设置为Activity的内容视图
SetContentView(gridLayout);
