Android Translate动画不在前面

我有以下XML代码，它不是一个活动，而是将通过许多活动回收的组件：

我曾尝试使用dart1.BringToFront（），但没有成功

PS：这是Xamarin.Android，但API与本机SDK相同，只是有一些细微的变化，比如名称是Pascal大小写，还有一些细微的变化。

如果您想让ImageView保持在一切之上，您可以将外部

线性布局

更改为

相对布局

，然后将Imageview放在xml的底部。它将始终停止在FrameLayout，因为它在其中。您必须为FrameLayout本身设置动画，或将ImageView放入父线性布局中

TranslateAnimation TranslateAnimation1 = new TranslateAnimation(0, 2000, 0, 0);
TranslateAnimation1.Duration = duration;
TranslateAnimation1.FillAfter = true;
TranslateAnimation1.AnimationEnd += TranslateAnimation1_AnimationEnd;
TranslateAnimation1.ZAdjustment = ContentZorder.Top;
dart1.StartAnimation(translateAnimation);
