示例1: UnbindView
public void UnbindView (View view)
{
if (view == null)
return;
var tag = view.GetBindingTag ();
if (tag != null) {
if (tag.Bindings != null) {
foreach (var binding in tag.Bindings) {
binding.Dispose();
}
tag.Bindings.Clear();
}
_viewTags.RemoveAll(weak => weak.Target == tag || weak.Target == null);
}
var viewGroup = view as ViewGroup;
if (viewGroup != null) {
var count = viewGroup.ChildCount;
for (var i = 0; i < count; i++) {
UnbindView(viewGroup.GetChildAt(i));
}
}
}示例2: BindViewTree
/// <summary>
/// Traverses the view hierarchy and updates the bindings.
/// </summary>
protected void BindViewTree(object dataSource, View view, IList<WeakReference> reusableBindings = null) {
var tag = view.GetBindingTag ();
if (tag != null) {
if (!tag.BindingEnabled)
return;
if (tag.OverrideDataSource)

if (tag.BindingDescriptions != null) {
if (dataSource == null) {

MvxTraceLevel.Warning,
"Binding view {0} with an empty data source.",

}
} else {
// Create bindings:
var bindings = this.GetService<IMvxBinder>()
.Bind(dataSource, view, tag.BindingDescriptions);

if (tag == null)
return;
if (view.GetBindingTag () != null) {
MvxBindingTrace.Trace (MvxTraceLevel.Warning,
"Trying to attach binding information to already configured view. Using binding elements on <fragment> tag?");
return;
}
