我在自定义控件内膨胀 MvxImageView 时遇到问题。
从我所做的研究中，我发现了几个嫌疑人
- 如果是这样，我应该添加什么？（我在 android 地图视图膨胀错误方面看到了这一点。
我创建的用户控件都错了吗？我看到了使用 SetContentView() 而不是 inflate 的建议，因为它通过 mvvmcross 机制传递 indlate 请求，但自定义视图中没有这种方法。
这是自定义控件布局：
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:local="http://schemas.android.com/apk/res/Com.TasteITAndroidClient" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Mvx.MvxImageView android:scaleType="centerCrop" android:id="@+id/Image" android:layout_width="match_parent" android:layout_height="wrap_content" />
这是 UserControl 的实现：
public class UserControl : LinearLayout
{
public UserControl(Context context, IAttributeSet attrs) : base(context,attrs)
{
LayoutInflater inflater = LayoutInflater.From(context);
inflater.Inflate (Resource.Layout.UserControl, this);
}
}
这是我使用它的地方：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:id="@+id/myButton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello" />
<TestApp.UserControl
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
我收到以下异常：
