Change ProgressBar let him meet his needs. As a general rule, the ProgressBar style will satisfy the requirements:

Activity code: Only one layout is displayed

Package Com.example.testcustomprogressbar;import Android.app.activity;import Android.os.bundle;import Android.view.menu;import Android.view.menuitem;public class Mainactivity extends Activity {@Overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (R.layout.activity_main);}}

XML interface:

<relativelayout xmlns:android= "http://schemas.android.com/apk/res/android" xmlns:tools= "http// Schemas.android.com/tools "android:layout_width=" match_parent "android:layout_height=" Match_parent "Tools:context        = "Com.example.testcustomprogressbar.MainActivity" > <progressbar android:id= "@+id/my_customprogressbar1" style= "@style/mycustom_progressbar1" android:layout_width= "wrap_content" android:layout_height= "Wrap_c         Ontent "android:layout_alignparenttop=" true "android:layout_centerhorizontal=" true "/> <progressbar Android:id= "@+id/my_customprogressbar2" style= "@style/mycustom_progressbar2" Android:layout_width= "W        Rap_content "android:layout_height=" wrap_content "android:layout_alignleft=" @+id/my_customprogressbar1 "        android:layout_below= "@+id/my_customprogressbar1" android:layout_margintop= "26DP"/> <ProgressBar    Android:id= "@+id/my_customprogressbar3"    style= "@style/mycustom_progressbar3" android:layout_width= "wrap_content" android:layout_height= "Wrap_con Tent "android:layout_alignleft=" @+id/my_customprogressbar2 "android:layout_below=" @+id/my_customprogressbar2        "android:layout_margintop=" 26DP "/> <progressbar android:id=" @+id/my_customprogressbar4 "         style= "@style/mycustom_progressbar_hor" android:layout_width= "200DP" android:layout_height= "Wrap_content" android:layout_below= "@+id/my_customprogressbar3" android:layout_centerhorizontal= "true" Android:lay        out_margintop= "22DP" android:max= "android:progress=" "android:secondaryprogress="/>        <progressbar android:id= "@+id/my_customprogressbar5" style= "@style/mycustom_progressbar_hor2" Android:layout_width= "200DP" android:layout_height= "wrap_content" android:layout_alignleft= "@+id/my_custompr OGRESSBAR4 "Android:layout_below= "@+id/my_customprogressbar4" android:layout_margintop= "26DP" android:max= "Androi" d:progress= "android:secondaryprogress="/> </RelativeLayout>

The first circular ProgressBar only rotates one image:

Code for Style:

<style name= "Mycustom_progressbar1" >        <item name= "android:indeterminatedrawable" > @drawable/ progressbar_ver_image</item>        <item name= "android:minheight" >30dp</item>        <item name= "Android:minwidth" >30dp</item>        <item name= "android:maxheight" >60dp</item>        <item Name= "Android:maxwidth" >60dp</item>    </style>

Progressbar_ver_image's Code:

<?
XML version= "1.0" encoding= "Utf-8"?><!--define a rotated animation, the picture is our own definition of--><rotate xmlns:android= "/http Schemas.android.com/apk/res/android "    android:drawable=" @drawable/resizeapi "    android:fromdegrees=" 0 "    android:pivotx= "50%"    android:pivoty= "50%"    android:todegrees= "></rotate>"

Another kind of circular ProgressBar uses an animation:

Style

<style name= "Mycustom_progressbar2" >        <item name= "android:indeterminatedrawable" > @drawable/ progressbar_ver_animation</item>        <item name= "android:minheight" >60dp</item>        <item Name= "Android:minwidth" >60dp</item>        <item name= "Android:maxheight" >100dp</item>        <item name= "Android:maxwidth" >100dp</item>    </style>

Progressbar_ver_animation's Code:

<?xml version= "1.0" encoding= "Utf-8"? ><animation-list xmlns:android= "http://schemas.android.com/apk/res/ Android ">    <item        android:drawable=" @drawable/ok1 "        android:duration="/> <item        android:drawable= "@drawable/ok2"        android:duration= "/>    <item        android:drawable=" @ Drawable/ok3 "        android:duration=" "/>    <item        android:drawable=" @drawable/ok4 "        android: duration= "/></animation-list>"

The third round ProgressBar uses shape to build drawable:

<style name= "Mycustom_progressbar3" >        <item name= "android:indeterminatedrawable" > @drawable/ progressbar_ver_shape</item>        <item name= "android:minheight" >60dp</item>        <item name= "Android:minwidth" >60dp</item>        <item name= "Android:maxheight" >100dp</item>        < Item Name= "Android:maxwidth" >100dp</item>    </style>

Progressbar_ver_shape's Code:

<?xml version= "1.0" encoding= "Utf-8"?><!--define a rotating animation, the picture is our own definition of shape--><rotate xmlns:android= "http ://schemas.android.com/apk/res/android "    android:fromdegrees=" 0 "    android:pivotx=" 50% "    android: Pivoty= "50%"    android:todegrees= ">    <shape        android:innerradiusratio=" 3 "        android:shape= "Ring"        android:thicknessratio= "8"        android:uselevel= "false" >        <gradient            android: Centercolor= "#FFFFFF"            android:centery= "0.50"            android:endcolor= "#1E90FF"            android:startcolor= "# 000000 "            android:type=" sweep "            android:uselevel=" false "/>    </shape></rotate>

The fourth type: horizontal ProgressBar copy and paste the system's style, then change:

<?xml version= "1.0" encoding= "Utf-8"? ><layer-list xmlns:android= "http://schemas.android.com/apk/res/ Android "> <item android:id=" @android: Id/background "> <shape> <corners Android:ra dius= "5dip"/> <gradient android:startcolor= "#ffff0000" Android:cen                    Tercolor= "#ffff0000" android:centery= "0.75" android:endcolor= "#ffff0000" Android:angle= "/> </shape> </item> <item android:id=" @android: ID /secondaryprogress "> <clip> <shape> <corners android:radius=" 5dip "/&gt                ;                        <gradient android:startcolor= "#800000ff" android:centercolor= "#800000ff" android:centery= "0.75" android:endcolor= "#800000ff" a  Ndroid:angle= "270"              /> </shape> </clip> </item> <item android:id= "@android: ID /progress "> <clip > <shape> <corners android:radius= "5dip"/> <gradient android:startcolor= "#ff00ff00" Android Oid:centercolor= "#ff00ff00" android:centery= "0.75" android:endcolor= "#ff00ff xx "android:angle="/> </shape> </clip> < /item> </layer-list>

This style can be met directly in ProgressBar, and of course we can define ProgressBar background progress secondprogress as a drawable, and then use:

Background

<shape xmlns:android= "Http://schemas.android.com/apk/res/android" >    <corners android:radius= "5dip"/ >    <gradient        android:angle= "android:centercolor="        #ffff0000 "        android:centery=" 0.75 "        android:endcolor= "#ffff0000"        android:startcolor= "#ffff0000"/></shape>

Progress

<shape xmlns:android= "Http://schemas.android.com/apk/res/android" >    <corners android:radius= "5dip"/ >    <gradient        android:angle= "android:centercolor="        #ff00ff00 "        android:centery=" 0.75 "        android:endcolor= "#ff00ff00"        android:startcolor= "#ff00ff00"/></shape>

Secondprogress:

<shape xmlns:android= "Http://schemas.android.com/apk/res/android" >    <corners android:radius= "5dip"/ >    <gradient        android:angle= "android:centercolor="        #800000ff "        android:centery=" 0.75 "        android:endcolor= "#800000ff"        android:startcolor= "#800000ff"/></shape>

This time the code in the style will be a little clearer:

<?
XML version= "1.0" encoding= "Utf-8"?
><layer-list xmlns:android= "Http://schemas.android.com/apk/res/android" >    <item        android:id= " @android: Id/background "        android:drawable=" @drawable/progressbar_hor_bg ">    </item>    <item Android:id= "@android: id/secondaryprogress" >        <clip android:drawable= "@drawable/progressbar_hor_second_ Progress ">        </clip>    </item>    <item android:id=" @android: id/progress ">        < Clip android:drawable= "@drawable/progressbar_hor_progress" >        </clip>    </item>    <! --Progress This place is written by the original author is a point 9 of the figure-      <!--<item android:id= "@android: id/progress" >          <clip>              <nine-patch android:src= "@drawable/progress_patch_galy"/>          </clip>      </item>   --></layer-list>

Hey.. Finally, to be honest: God General man's original blogger blog Connection http://blog.csdn.net/mad1989/article/details/38042875

By the way, the code is still posted. Always feel more comfortable reading the code directly in the IDE: http://download.csdn.net/detail/u010399316/9000197
