自定义控件之仿QQ提示Dialog

上次无意之间删除了一个好友(呃…删除好友…)就发现了QQ的删除提示框是由上往下提示,感觉挺霸气的(可能是因为删除好友的心情吧…0.0,唉不管了先上图)

我的思路是这样的
继承于Dialog,设置Dialog样式与动画在Handler中控制Dialog的销毁
代码:

package com.example.downlist.view.dialog;

import android.app.Activity;
import android.app.Dialog;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Color;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.ColorDrawable;
import android.graphics.drawable.Drawable;
import android.os.Handler;
import android.os.Message;
import android.renderscript.RenderScript;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.annotation.StyleRes;
import android.util.DisplayMetrics;
import android.view.Gravity;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.view.WindowManager;
import android.widget.FrameLayout;
import android.widget.RelativeLayout;
import android.widget.TextView;

import com.example.downlist.R;
import com.example.downlist.utils.BlurBitmapUtil;
import com.example.downlist.utils.UIUtlis;

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


    <style name="MyDialog" parent="Base.V11.Theme.AppCompat.Light.Dialog">
        <item name="android:windowBackground">@color/back</item> <!-- 背景透明 -->

        <item name="@android:windowExitAnimation">@anim/dialog_exit</item>
        //退出时的动画

    </style>
</resources>

使用:

    DialogThis.ToastDialog(activity, title,message);
    DialogThis.ToastDialog(activity, message);
