推荐答案

首先是你可以使用正常的按键让您在与放幻灯片;出面板。现在，该怎么办呢？

First of all yes you can use normal button for your slide in & out panel. Now, how to do it?

首先为你面板创建一个单独的布局xml文件如 panel.xml 。

First of all create a separate layout xml file for you panel e.g. "panel.xml".

现在使用包含标签在你的游戏xml文件，并将其设置的比重：TOP 和知名度：GONE 并设置它的ID，以面板即

Now use the include tag in your game xml file and set it's gravity : TOP and visibility : GONE and set it's id to panel i.e.

android:id="@+id/panel";

现在创建一个文件夹名为动画里面你的项目的资源文件夹中。在这里，创建两个XML文件slide_in.xml＆安培; slide_out.xml这些XML苍蝇将帮助您获得幻灯片在＆放大器;出来的效果。 code这些XML文件如下

Now create a folder named "anim" inside your projects res folder. Here create two xml files slide_in.xml & slide_out.xml these xml flies will help you in getting the slide in & out effect. Code for these xml file is as follow

slide_in.xml：

slide_in.xml:

<?xml version="1.0" encoding="utf-8"?>
    <translate xmlns:android="http://schemas.android.com/apk/res/android"
     android:fromYDelta="-100%p" 
     android:toYDelta="0%p"
     android:duration="3000"/>

slide_out.xml：

slide_out.xml:

<?xml version="1.0" encoding="utf-8"?>
    <translate xmlns:android="http://schemas.android.com/apk/res/android"
     android:fromYDelta="0%p" 
     android:toYDelta="-100%p"
     android:duration="3000"/>

现在要求所有的事情构建您的幻灯片中和放大器;从面板已经准备就绪。

Now all the things required to build your slide in & out panel are ready.

实施

请注意：保持一个布尔变量的 isPanelVisible 以保持面板的可见性状态的检查

NOTE: maintain a boolean variable isPanelVisible to keep check of visibility state of the panel.

创建两个动画类对象的的slideIn ＆安培; 滑出和一个视图类对象的板作为我们包含在游戏中的XML文件的panel.xml，然后初始化它们是这样的：

Create two Animation class object slideIn & slideOut and one View class object panel for the panel.xml which we included in the game xml file, then initialize them like this:

Animation slideIn= AnimationUtils.loadAnimation(getApplicationContext(),
            R.anim.slide_in);
Animation slideOut= AnimationUtils.loadAnimation(getApplicationContext(),
            R.anim.slide_out);
View panel = findViewById(R.id.panel);

现在，当在用户单击按钮来显示和放幻灯片;出onClickListener（）方法中板做这样的事情：

Now when the user clicks on the button to show the slide in & out panel inside the onClickListener() method do something like this:

if(isPanelVisible){
    isPanelVisible = false;
    panel.startAnimation(slideOut);
    panel.setVisibility(View.Gone);
} else{
    isPanelVisible = true;
    panel.startAnimation(slideIn);
    panel.setVisibility(View.Visible);
}
