花样android Progressbar http://www.eoeandroid.com/thread-1081-1-1.html

xml布局文件需加入如下的进度条构件:
<ProgressBar
android:id="@+id/loadProgressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminateDrawable="@drawable/progressbar" />
其中的indeterminteDrawable属性就是用来设置进度条颜色等属性的,其内容如下:
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360" >
<shape
android:innerRadiusRatio="3"
android:shape="ring"
android:thicknessRatio="8"
android:useLevel="false" >
<gradient
android:centerColor="#FFFFFF"
android:centerY="0.50"
android:endColor="#FFFF00"
android:startColor="#000000"
android:type="sweep"
android:useLevel="false" />
</shape>
</rotate>

三种方式实现自定义圆形页面加载中效果的进度条:

默认情况下Indeterminate Progressbar是白色的,如果容器的背景也是白色的,这样就根本看不到Progressbar了。
幸好Android自带了一些反转样式,你可以采用其中一个合适的:
<ProgressBar style="@android:style/Widget.ProgressBar.Inverse"/>
<ProgressBar style="@android:style/Widget.ProgressBar.Large.Inverse"/>
<ProgressBar style="@android:style/Widget.ProgressBar.Small.Inverse"/>
进度条:
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<ProgressBar
android:id="@+id/circleProgressBar"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
mce_style="?android:attr/progressBarStyleLarge" />
一、通过动画实现
定义res/anim/loading.xml如下:
<?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/loading_01"
android:duration="150"/>
<item
android:drawable="@drawable/loading_02"
android:duration="150"/>
<item
android:drawable="@drawable/loading_03"
android:duration="150"/>
<item
android:drawable="@drawable/loading_04"
android:duration="150"/>
<item
android:drawable="@drawable/loading_05"
android:duration="150"/>
<item
android:drawable="@drawable/loading_06"
android:duration="150"/>
<item
android:drawable="@drawable/loading_07"
android:duration="150"/>
</animation-list>
在layout文件中引用如下:
<ProgressBar
android:id="@+id/loading_process_dialog_progressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminate="false"
android:indeterminateDrawable="@anim/loading" />
二、通过自定义颜色实现
定义res/drawable/dialog_style_xml_color.xml如下:
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360" >
<shape
android:innerRadiusRatio="3"
android:shape="ring"
android:thicknessRatio="8"
android:useLevel="false" >
<gradient
android:centerColor="#FFDC35"
android:centerY="0.50"
android:endColor="#CE0000"
android:startColor="#FFFFFF"
android:type="sweep"
android:useLevel="false" />
</shape>
</rotate>
在layout文件中引用如下:
<ProgressBar
android:id="@+id/loading_process_dialog_progressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminate="false"
android:indeterminateDrawable="@drawable/dialog_style_xml_color" />
三、使用一张图片进行自定义
定义res/drawable/dialog_style_xml_icon.xml如下:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<rotate
android:drawable="@drawable/dialog_progress_round"
android:fromDegrees="0.0"
android:pivotX="50.0%"
android:pivotY="50.0%"
android:toDegrees="360.0" />
</item>
</layer-list>
在layout文件中引用如下:
<ProgressBar
android:id="@+id/loading_process_dialog_progressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminate="false"
android:indeterminateDrawable="@drawable/dialog_style_xml_icon" />
或者
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background">
<shape>
<corners android:radius="5dip" />
<gradient android:startColor="#ff9d9e9d"
android:centerColor="#ff5a5d5a"
android:centerY="0.75"
android:endColor="#ff747674"
android:angle="270"
/>
</shape>
</item>
<item android:id="@android:id/secondaryProgress">
<clip>
<shape>
<corners android:radius="5dip" />
<gradient android:startColor="#80ffd300"
android:centerColor="#80ffb600"
android:centerY="0.75"
android:endColor="#a0ffcb00"
android:angle="270"
/>
</shape>
</clip>
</item>
<item android:id="@android:id/progress">
<clip>
<shape>
<corners android:radius="5dip" />
<gradient android:startColor="@color/progress_start"
android:endColor="@color/progress_end"
android:angle="270" />
</shape>
</clip>
</item>
</layer-list>
代码中设置:
mProgress = (ProgressBar) findViewById(R.id.progress_bar);
Drawable d = this.getResources().getDrawable(R.drawable.my_progress);
mProgress.setProgressDrawable(d);
