Android自定义进度条主要是修改ProgressBar的style，弹窗则是在Dialog里显示ProgressBar。
直接上代码。
在style.xml里加入如下代码：
|
1

3
4
5

7
|
<style name="ProgressBar_Mini" parent="@android:style/Widget.ProgressBar.Horizontal"> <item name="android:maxHeight">50dip</item> <item name="android:minHeight">8dip</item> <item name="android:indeterminateOnly">false</item> <item name="android:indeterminateDrawable">@android:drawable/progress_indeterminate_horizontal</item> <item name="android:progressDrawable">@drawable/progressbar_mini</item> </style> |
|

<style name="dialog" parent="@android:style/Theme.Dialog"> <item name="android:windowFrame">@null</item> <item name="android:windowIsFloating">true</item> <item name="android:windowIsTranslucent">true</item> <item name="android:windowNoTitle">true</item> <item name="android:backgroundDimEnabled">true</item> <item name="android:windowBackground">@color/transparent</item> </style> |
