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; } }</pre><br> <div style="text-align:left"><span style="font-family:Arial,Helvetica,sans-serif"></span></div> <pre></pre> <br> <br>
