Android 自定義progressDialog

1.
導入CustomProgressDialog.java

2.
styles.xml：

 <style name="CustomProgressDialog" parent="@android :style/Theme.Dialog">
        <item name="android:windowBackground">@android :color/transparent</item>
        <item name="android:windowNoTitle">true</item>
  <item name="android:windowFrame">@null</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowAnimationStyle">@android :style/Animation.Dialog</item>
        <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
     </style>

3.
\layout中定義本身的佈局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="horizontal">
    <ImageView
        android:id="@+id/loadingImageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@anim/progress_round"/>
    <TextView
        android:id="@+id/id_loadingmsg"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:textSize="20dp"/>
</LinearLayout>

4.
實現轉動的效果，循環顯示圖片：
anim中progress_round.xml

<?xml version="1.0" encoding="utf-8"?>
<animation-list
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:oneshot="false">
    <item android:drawable="@drawable/progress_1" android:duration="200"/>
    <item android:drawable="@drawable/progress_2" android:duration="200"/>
    <item android:drawable="@drawable/progress_3" android:duration="200"/>
    <item android:drawable="@drawable/progress_4" android:duration="200"/>
    <item android:drawable="@drawable/progress_5" android:duration="200"/>
    <item android:drawable="@drawable/progress_6" android:duration="200"/>
    <item android:drawable="@drawable/progress_7" android:duration="200"/>
    <item android:drawable="@drawable/progress_8" android:duration="200"/>
</animation-list>
