 （1）自定义DefineProgressDialog类，继承ProgressDialog，复写onCreate（）方法

 public class DefineProgressDialog extends ProgressDialog{
 private String message;
 private TextView define_progress_msg;
 public DefineProgressDialog(Context context) {
 super(context);
message = "正在载入...";
// TODO Auto-generated constructor stub
}
 public DefineProgressDialog(Context context,String message){
 super(context);
 this.message = message;
}
@Override
 protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
 super.onCreate(savedInstanceState);
setContentView(R.layout.define_progress_dialog);
define_progress_msg = (TextView) findViewById(R.id.define_progress_msg);
define_progress_msg.setText(message);
}

}

（2）define_progress_dialog.xml

"1.0" encoding="utf-8"?>
"http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/progress_background"
android:orientation="vertical"
android:paddingBottom="10sp"
android:paddingTop="10sp"
android:paddingLeft="10sp"
android:paddingRight="10sp" >

android:id="@+id/ios_progressbar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
style="@style/DefineprogressBarStyleSmall"/>

android:id="@+id/define_progress_msg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:textSize="12sp"/>

（3）设置进度条样式，自定义DefineprogressBarStyleSmall:

"1.0" encoding="utf-8"?>

"DefineprogressBarStyleSmall"</span> parent=<span class="string">"android:style/Widget.ProgressBar"</span>></li> 
    <li><item name=<span class="string">"android:indeterminateDrawable"</span>><span class="annotation">@drawable</span>/progress</item></li> 
    <li class="alt"><item name=<span class="string">"android:minWidth"</span>>48dp</item></li> 
    <li><item name=<span class="string">"android:maxWidth"</span>>48dp</item></li> 
    <li class="alt"><item name=<span class="string">"android:minHeight"</span>>48dp</item></li> 
    <li><item name=<span class="string">"android:maxHeight"</span>>48dp</item></li> 
    <li class="alt">

（4）再定义一个进度条背景图片，设置该图片的动画，绕中心点旋转，在drawable下添加progress.xml：

[java] view plaincopyprint?

"1.0" encoding="utf-8"?>
"http://schemas.android.com/apk/res/android" >


android:pivotX="50%"
android:pivotY="50%"
android:fromDegrees="0"
android:toDegrees="360"
android:drawable="@drawable/progress_round"
>
