Android的：如何以编程方式添加按钮来查看 [英] Android: How to programmatically add button to view
问题描述
在我的Android活动中，我创建一个继承SurfaceView（使用MonoDroid在语法，这样轻微的变化）的自定义视图：
In my Android activity, I create a custom view that extends SurfaceView (using MonoDroid so slight variations in syntax):
class FriendsView : SurfaceView
{
...
public FriendsView(Context context) : base(context)
{
... create my custom view ...
}
}
在我的活动课，我设置的内容视图到视图：
In my Activity class, I set the content view to the view:
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
ViewGroup.LayoutParams layoutParams = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FillParent, ViewGroup.LayoutParams.FillParent);
FriendsView friendsView = new FriendsView(this);
SetContentView(friendsView, layoutParams);
}
我想添加一个按钮的观点，但不知道如何做到这一点。一切我已经阅读从开始来看main.xml中的观点，但我不明白如何使用此声明一个按钮，这是在我看来可见。同样，我找不到在任何活动或视图类，它可以让我增加一个按钮对象编程的方法。
I want to add a button to the view, but cannot work out how to do this. Everything I have read starts from the point of view of the main.xml, but I don't see how to use this to declare a button which is visible in my view. Equally, I cannot find a method in either Activity or View classes which lets me add a Button object programatically.
我确信我失去了一些东西概念，但欢迎任何帮助，让我朝着正确的方向发展。
I feel sure I am missing something conceptually, but would welcome any help to get me going in the right direction.
推荐答案
如果我理解正确的话，你看到你的friendsView就好了，但你要添加一个按钮来呢？ 我不知道是什么样的观点你FriendsView是的，但假设它是你可以增加孩子的到（如LinearLayout中或某事），你应该能够做到这一点（只是从我的头顶）
If I understand correctly you see your friendsView just fine, but you want to add a button to it? I don't know what kind of View your FriendsView is, but assuming it is something you can add childs to (like a linearLayout or something), you should be able to do this (just from the top of my head)
//assuming you have a friendsView object that is some sort of Layout.
Button yourButton = new ImageButton(this);
//do stuff like add text and listeners.
friendsView.addView(yourButton);
如果没有在friendsView要添加一个孩子，你可以找到它使用 findViewById（）（添加IDS到您的元素，如果你想一些其他的元素找他们这样的）
If there is some other element in friendsView you want to add a child to, you can just find it using findViewById() (add ids to your elements if you want to find them like this)
