收藏提示动画效果

需求：点击收藏，屏幕中间弹出收藏提示动画，3秒后消失，且悬浮在app之上（即不会随着viewpager滑动和activity跳转而消失）

解决方案：

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:id="@+id/layout"
    android:background="#00ffffff">

    <ImageView
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/tips_collection_success" />
</LinearLayout>

方案一：使用dialog

import android.app.Dialog;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.animation.AlphaAnimation;
import android.view.animation.Animation;
import android.widget.ImageView;
import android.widget.LinearLayout;

/**

public class CollectionAnimDialog {

    private Context context;
    private Dialog dialog;
    private View view;
    private LinearLayout layout;

    public CollectionAnimDialog(Context context) {
        this.context = context;
    }

    public CollectionAnimDialog builder() {
        view = LayoutInflater.from(context).inflate(R.layout.collection_anim_dialog, null);
        dialog = new Dialog(context, R.style.CollectionAnimDialogStyle);
        layout = (LinearLayout) view.findViewById(R.id.layout);
        layout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
        image = (ImageView) view.findViewById(R.id.image);
        dialog.setContentView(view);
        return this;
    }

    public void show() {
        dialog.show();
        collectionAnim();
    }

    /**
     * 收藏动画
     */
    private void collectionAnim() {
        AlphaAnimation alpha = new AlphaAnimation(1, 0);
        alpha.setDuration(3000);
        alpha.setFillAfter(true);
        alpha.setRepeatCount(0);
        layout.startAnimation(alpha);
        alpha.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {

            }

            @Override
            public void onAnimationEnd(Animation animation) {
                dialog.dismiss();
            }

            @Override
            public void onAnimationRepeat(Animation animation) {

            }
        });
    }
}

dialog样式

<!-- CollectionAnimDialog收藏动画对话框样式 -->
<style name="CollectionAnimDialogStyle" parent="@android:style/Theme.Dialog">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowFrame">@null</item>
    <item name="android:backgroundDimEnabled">false</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsTranslucent">true</item>
</style>

方案二：Toast(推荐使用)

//收藏动画
Toast toast = new Toast(App.getApplication());
View view = LayoutInflater.from(App.getApplication()).inflate(R.layout.collection_anim_dialog, null);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.setView(view);
toast.show();

Toast简单明了，动画系统自带，完美
