如何在android中动态添加UI元素

Question

我一直在寻找如何纯粹通过代码创建UI元素

我该怎么做？

RelativeLayout mainLayout = FindViewById<RelativeLayout>(Resource.Id.MainRelativeLayout);
TextView newText = new TextView(this);
newText.Text = "HEY THERE NEW TEXT MADE VIA CODE";
mainLayout.AddView(newText);


// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);

Answer 1

事实证明，您需要在设置内容视图后放置代码

/ Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);

RelativeLayout mainLayout = FindViewById<RelativeLayout>(Resource.Id.MainRelativeLayout);
TextView newText = new TextView(this);
newText.Text = "HEY THERE NEW TEXT MADE VIA CODE";
mainLayout.AddView(newText);

哦，你需要在FindViewById＆lt;下指定类型TYPE＆gt;
