问题描述
我试图创建使用我自己的布局一个DialogFragment。
我见过一对夫妇不同的方法。有时,布局设置在OnCreateDialog是这样的:(我使用的是单声道,但我已经得到了一定程度用于Java的)
公众覆盖Android.App.Dialog OnCreateDialog(包savedInstanceState)
{
base.OnCreateDialog(savedInstanceState);
AlertDialog.Builder B =新AlertDialog.Builder(活动);
//等等等等等等
LayoutInflater I = Activity.LayoutInflater;
b.SetView(i.Inflate(Resource.Layout.frag_SelectCase,NULL));
返回b.Create();
}
这第一种方式对我的作品......直到我想使用 findViewByID。
打完有点谷歌上搜索我的尝试涉及重写第二种方法 OnCreateView
所以,我注释掉两行 OnCreateDialog
中的设置布局,然后添加这样的:
公众覆盖Android.Views.View OnCreateView(LayoutInflater充气,容器的ViewGroup,捆绑savedInstanceState)
{
视图V = inflater.Inflate(Resource.Layout.frag_SelectCase,集装箱,假);
//应该可以在这里使用FindViewByID ...
返回伏;
}
这给了我一个美丽的错误:
11-05 22:00:05.381:E / AndroidRuntime(342):致命异常:主要
11-05 22:00:05.381:E / AndroidRuntime(342):android.util.AndroidRuntimeException:requestFeature()必须添加内容之前调用
我难倒。
我猜你是不是作用域 findViewById()
来)由返回查看膨胀(
,尝试这样的:
查看视图= i.inflate(Resource.Layout.frag_SelectCase,NULL);
//现在使用view.findViewById()做你想要什么
b.setView(视图);
返回b.create();
I'm trying to create a DialogFragment using my own Layout.
I've seen a couple different approaches. Sometimes the layout is set in OnCreateDialog like this:(I'm using Mono but I've gotten somewhat used to Java)
public override Android.App.Dialog OnCreateDialog (Bundle savedInstanceState)
{
base.OnCreateDialog(savedInstanceState);
AlertDialog.Builder b = new AlertDialog.Builder(Activity);
//blah blah blah
LayoutInflater i = Activity.LayoutInflater;
b.SetView(i.Inflate(Resource.Layout.frag_SelectCase, null));
return b.Create();
}
This first approach works for me... until I want to use findViewByID.
so after a bit of googling I tried the second approach which involves overriding OnCreateView
So I commented out two lines of OnCreateDialog
that set the Layout and then added this:
public override Android.Views.View OnCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View v = inflater.Inflate(Resource.Layout.frag_SelectCase, container, false);
//should be able to use FindViewByID here...
return v;
}
which gives me a lovely error:
11-05 22:00:05.381: E/AndroidRuntime(342): FATAL EXCEPTION: main
11-05 22:00:05.381: E/AndroidRuntime(342): android.util.AndroidRuntimeException: requestFeature() must be called before adding content
I'm stumped.
I would guess that you are not scoping findViewById()
to the View returned by inflate()
, try this:
View view = i.inflate(Resource.Layout.frag_SelectCase, null);
// Now use view.findViewById() to do what you want
b.setView(view);
return b.create();
