Android Custom ProgressDialog Implementation

First look at the effect:

1.string.xml file, ProgressDialog is inherited and dialog, first set the ProgressDialog style, set the background transparent color.

 <style name= "Customdialog" parent= "@android: Style/theme.dialog" > <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> <style name= "Customprogressdialog" parent= "@style/customdialog" > <item name= "Android:windowbackground" &G t; @android:color/transparent</item> <item name= "Android:windownotitle" > true  </item> </style> 

2.customprogressdialog.xml file, define your own layout, because I need only a progress bar and a series of display content, so layout comparison orders

<?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_tv_loadingmsg"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"android:layout_gravity= "Center_vertical"android:textsize= "20DP"/> </LinearLayout>

3.progress_round.xml file. This file loops through the images in order to achieve the effect of rotation.

<?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=" "/>     <item android:drawable=" @drawable/progress_2 "Android: duration= "/>     <item android:drawable=" @drawable/progress_3 "android:duration="/> "     < Item android:drawable= "@drawable/progress_4" android:duration= "/>     <item android:drawable=" @drawable /progress_5 "android:duration=" "/>     <item android:drawable=" @drawable/progress_6 "android:duration=" "/>     <item android:drawable=" @drawable/progress_7 "android:duration=",/> <item     android :d rawable= "@drawable/progress_8" android:duration= "/> </animation-list>

4.customprogressdialog.java file
