Dialog 自定义使用2(进度条)

1:  自定义的Dialog 代码:

public class IphoneProgersssDialog extends Dialog {
   private Context context;
   private ImageView img;
   private TextView txt;
       public IphoneProgersssDialog(Context context) {
               super(context, R.style.iphone_progress_dialog);
               this.context=context;
               //加载布局文件
               LayoutInflater inflater=(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
               View  view=inflater.inflate(R.layout.iphone_progress_dialog, null); 
               img=(ImageView) view.findViewById(R.id.iphone_progress_dialog_img);     // 进度图片
               txt=(TextView) view.findViewById(R.id.iphone_progress_dialog_txt);
               //给图片添加动态效果
               Animation anim=AnimationUtils.loadAnimation(context, R.anim.progressbar);
               img.setAnimation(anim);       //  变成旋转
               txt.setText(R.string.iphone_progressbar_dialog_txt);
               //dialog添加视图
               setContentView(view);

       }

       public void setMsg(String msg){   //进度提示消息
               txt.setText(msg);
       }
       public void setMsg(int msgId){
               txt.setText(msgId);
       }

}

 2 ,dialog定义样式

<style name="iphone_progress_dialog" parent="@android:style/Theme.Dialog">    //构造方法中
       <item name="android:windowFrame">@null</item> <!--Dialog的windowFrame框为无 --> 
       <item name="android:windowIsFloating">true</item><!-- 是否漂现在activity上 -->
       <item name="android:windowIsTranslucent">true</item><!-- 是否半透明 -->
       <item name="android:windowNoTitle">true</item>
       <item name="android:backgroundDimEnabled">false</item>    //模糊
       <item name="android:windowBackground">@drawable/load_bg</item>   //dialog背景
   </style>

3.定义动画文件  progressbar.xml

<?xml version="1.0" encoding="utf-8"?>
  <set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false" >
  <rotate 
       android:interpolator="@android:anim/linear_interpolator"
       android:pivotX="50%"
       android:pivotY="50%"
       android:fromDegrees="0"
       android:toDegrees="+360"
       android:duration="1000"
       android:startOffset="-1"
       android:repeatMode="restart"
       android:repeatCount="-1"/>
</set>
