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,可上下弹跳,并在屏幕中央显示。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:

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;
}
}
