Android仿一点资讯收藏Toast动画效果

最近在做一个项，有一个收藏的功能。后来看到了一点资讯的收藏动画，感觉不错，所有自己就实现了一下。

这是效果：

附上完整的代码，其中Animation_Toast为动画：

<div style="text-align: left;"><span style="font-family: Arial, Helvetica, sans-serif;"></span></div><pre name="code" class="java">public class CollectToast {
 private static CollectToast toastCollectSucceed = null;
 private Toast toast = null;
 private TextView text;
 private CollectToast() {}
 /**
  * 单例模式
  *
  * @return
  */
 public static CollectToast createToast() {
   if (toastCollectSucceed == null) {
     toastCollectSucceed = new CollectToast();
   }
   return toastCollectSucceed;
 }
 /**
  * 显示Toast
  *
  * @param context
  * @param root
  * @param tvString
  * @param result 是否成功
  */
 public Toast showToast(Context context, ViewGroup root, String tvString, int duration, boolean result) {
   toast = null;
   int styleId = R.style.Animation_Toast;
   if (toast == null) {
     View layout = LayoutInflater.from(context).inflate(R.layout.toast_collect_layout, root);
     text = (TextView) layout.findViewById(R.id.title_tv);
     ImageView imageView = (ImageView) layout.findViewById(R.id.iv);
     if (result)
       imageView.setBackgroundDrawable(DrawableUtil.getImageDrawable(context, R.mipmap.doneicon_popup_textpage));
     else
       imageView.setBackgroundDrawable(DrawableUtil.getImageDrawable(context, R.mipmap.close_popup_textpage));
     text.setText(tvString);
     toast = new Toast(context);
     toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
     toast.setDuration(duration);
     toast.setView(layout);
     toast.show();
   } else {
     text.setText(tvString);
     toast.show();
   }
   //通过反射给Toast设置动画
   try {
     Object mTN = null;
     mTN = getField(toast, "mTN");
     if (mTN != null) {
       Object mParams = getField(mTN, "mParams");
       if (mParams != null
           && mParams instanceof WindowManager.LayoutParams) {
         WindowManager.LayoutParams params = (WindowManager.LayoutParams) mParams;
         params.windowAnimations = styleId;
       }
     }
   } catch (Exception e) {
     e.printStackTrace();
   }
   return toast;
 }
 /**
  * 反射字段
  *
  * @param object  要反射的对象
  * @param fieldName 要反射的字段名称
  * @return
  * @throws NoSuchFieldException
  * @throws IllegalAccessException
  */
 private static Object getField(Object object, String fieldName) throws NoSuchFieldException, IllegalAccessException {
   Field field = object.getClass().getDeclaredField(fieldName);
   if (field != null) {
     field.setAccessible(true);
     return field.get(object);
   }
   return null;
 }
