setAnimationStyle() 的显式动画，我的选择是什么？

我想使用 setAnimationStyle() 尝试弹出窗口的不同动画样式，但我很难理解文档。

developer.android.com 上说：“弹出窗口出现和消失时使用的动画样式。设置为 -1 表示默认动画，0 表示无动画，或设置为显式动画的资源标识符。”

它没有给出任何示例，也没有告诉我可用的资源选择。我怀疑最适合我目的的动画将从右侧滑入......这是否作为一个选项存在？我可以从列表中选择这些东西还是我必须以某种方式创建自己的东西？

EDIT:我当前制作弹出窗口的代码是这样的（简化的）：

public void completed_dialog()
{
  runOnUiThread(new Runnable()
  {
    public void run()
    {

      View layout = inflater.inflate(R.layout.endofgame, null, false);

      Button b1 = (Button) layout.findViewById(R.id.pu_menu);
      Button b2 = (Button) layout.findViewById(R.id.pu_repeat);
      Button b3 = (Button) layout.findViewById(R.id.pu_next);

      b1.setBackgroundResource(R.drawable.custom_menu_but);
      b2.setBackgroundResource(R.drawable.custom_repeat_but);
      b3.setBackgroundResource(R.drawable.custom_next_but);

      b1.setOnClickListener(menu_button_click_listener);
      b2.setOnClickListener(repeat_button_click_listener);
      b3.setOnClickListener(next_button_click_listener);

      final PopupWindow pw = new PopupWindow(layout, canvas_width, 
                                                       canvas_width /2,  true);

      pw.setAnimationStyle(android.R.style.Animation_Dialog);
      pw.showAtLocation(game_frame_layout, Gravity.CENTER, 0, 0);
    }
  }
}

我现在将以下内容放入文件 res/anim/test.xml 中：

<?xml version="1.0" encoding="utf-8"?>

    <set xmlns:android="http://schemas.android.com/apk/res/android">
            <scale
                    android:fromXScale="0.3" android:toXScale="1.0"
                    android:fromYScale="0.3" android:toYScale="1.0"
                    android:pivotX="0%" android:pivotY="0%"
                    android:duration="@android:integer/config_shortAnimTime"
            />
            <alpha
                    android:interpolator="@android:anim/decelerate_interpolator"
                    android:fromAlpha="0.0" android:toAlpha="1.0"
                    android:duration="@android:integer/config_shortAnimTime"
            />
    </set>

原始代码为 pw.setAnimationStyle(android.R.style.Animation_Dialog);工作正常，只要对话框出现标准动画 - 但如果我用 pw.setAnimationStyle(R.anim.test) 交换该行；没有动画。我不知道为什么。

这是工作示例setAnimationStyle()我这边：

res/anim/in.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/decelerate_interpolator">
    <translate 
        android:fromYDelta="854" 
        android:toYDelta="0"
        android:duration="1000"/>
</set>

res/anim/out.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">  
    <translate android:interpolator="@android:anim/decelerate_interpolator"
        android:fromYDelta="0"
        android:toYDelta="854" 
        android:duration="10000"
    />
</set>

布局/main.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/layout"
    >
    <Button
        android:id="@+id/btn_show"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:text="show"
        />
</RelativeLayout >

布局/popup.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="vertical"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:background="#cccccc" 
    > 
    <Button 
        android:id="@+id/btn_dismiss"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="dismiss"/>
</LinearLayout>

值/styles.xml：

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="PopupAnimation" parent="android:Animation" mce_bogus="1">      
         <item name="android:windowEnterAnimation">@anim/in</item>  
        <item name="android:windowExitAnimation">@anim/out</item>  
    </style>  
</resources>

值/strings.xml：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="hello">Hello World, MainActivity!</string>
    <string name="app_name">Popupwindow</string>
</resources>

MainActivity.java :

public class MainActivity extends Activity {
    /** Called when the activity is first created. */
    boolean flag =false;
    PopupWindow popupWindow;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        init();
    }
    public void init() {
        Button btn_show = (Button) findViewById(R.id.btn_show);
        LayoutInflater inflater = LayoutInflater.from(this);
        View layout = inflater.inflate(R.layout.popup, null);
        popupWindow =new PopupWindow(layout, LayoutParams.FILL_PARENT,
                LayoutParams.FILL_PARENT);
        Button btn_dismiss = (Button) layout.findViewById(R.id.btn_dismiss);
        btn_dismiss.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                openMenu();
            }
        });
        btn_show.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                openMenu();
            }
        });
    }

    public void btn_showOnClicked() {
        openMenu();
    }

    public void btn_dismissOnClicked() {
        openMenu();
    }

    public void openMenu() {
        if (!flag) {
            popupWindow.setAnimationStyle(R.style.PopupAnimation);
            popupWindow.showAtLocation(findViewById(R.id.btn_show), Gravity.NO_GRAVITY, 0, 0);
            popupWindow.setFocusable(true);
            popupWindow.update();
            flag =true;
        } else {
            popupWindow.dismiss();
            popupWindow.setFocusable(false);
            flag =false;
        }
    }
}

并在您的代码中将动画文件添加为样式：

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="test" parent="android:Animation" mce_bogus="1">      
         <item name="android:windowEnterAnimation">@anim/test</item>  
    </style>  
</resources>

并在代码中：

pw.setAnimationStyle(android.R.style.test);

谢谢，编码愉快！
