5         <item name="android:windowBackground">@drawable/dialog_background_style</item>
6     </style>

代码实现：

 1 package com.wangzhen.view;
 2 
 3 import com.wangzhen.bottomwindow.R;
 4 
 5 import android.app.Dialog;
 6 import android.content.Context;
 7 import android.os.Bundle;
 8 import android.view.LayoutInflater;
 9 import android.view.View;
10 import android.view.animation.Animation;
11 import android.view.animation.AnimationUtils;
12 import android.widget.ImageView;
13 
14 public class MyProgressDialog extends Dialog {
15     private Context mContext;
16     private LayoutInflater mInflater;    
17 
18     public MyProgressDialog(Context context) {
19         super(context, R.style.loading_dialog);
20         mContext = context;
21         mInflater = LayoutInflater.from(mContext);
22     }
23 
24     @Override
25     protected void onCreate(Bundle savedInstanceState) {
26         super.onCreate(savedInstanceState);
27         View view = mInflater.inflate(R.layout.mydialog_layout, null);
28         ImageView ImageView_Icon = (ImageView) view
29                 .findViewById(R.id.ImageView_Icon);
30         // 为ImageView添加动画
31         Animation animation = AnimationUtils.loadAnimation(mContext,
32                 R.anim.anim_dialog);
33         ImageView_Icon.startAnimation(animation);        
34         setContentView(view);
35     }
