Android 线性布局动画

发布于 2024-12-09 20:18:08 字数 770 浏览 1 评论 0原文

您好，我有一个线性布局，我将其用作列表视图中的底部栏，当按下拉链时，我会显示布局并在其他时候隐藏它。我认为将其向上滑动会更好，因此我编写了以下内容和一个动画 xml，一切都运行良好。然而，当它滑入时，它会显示布局滑入的黑色背景。我如何更改该背景以显示为透明，以便列表视图显示并且布局在列表视图上滑动而不是黑色背景。

LinearLayout mainLayout=(LinearLayout)this.findViewById(R.id.bottombar);
Animation slideUp = AnimationUtils.loadAnimation(this, R.anim.slide_up_in);
mainLayout.startAnimation(slideUp);
mainLayout.setVisibility(LinearLayout.VISIBLE);

感谢您的帮助

这是选择 zip 之前的列表视图

这是幻灯片之前的内容（白色背景现在将活动主题更改为浅色）

输入此处图像描述

这就是幻灯片中间部分（抱歉吐司）

Hi i have a linear layout which i'm using as a bottom bar in a listview and when zips are pressed i show the layout and hide it at other times. I decided it would look nicer to slide it up so i wrote the following and an animation xml which all works well. However when it slides in it shows a black background where the layout is sliding into. How can i change that background to show as transparent so the listview shows and the layout slides over the listview rather than a black background.

LinearLayout mainLayout=(LinearLayout)this.findViewById(R.id.bottombar);
Animation slideUp = AnimationUtils.loadAnimation(this, R.anim.slide_up_in);
mainLayout.startAnimation(slideUp);
mainLayout.setVisibility(LinearLayout.VISIBLE);

Thanks for any help
