android 自定义水平和圆形progressbar 只定义一些style就可以

效果图:



修改progressbar 让他满足自己的需求一般来说只修改一下,progressbar的style就可以满足需求了:

activity代码:仅仅显示一个布局而已

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 {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}

xml界面:

<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_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />

<ProgressBar
android:id="@+id/my_customprogressbar2"
style="@style/mycustom_progressbar2"
android:layout_width="wrap_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_content"
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:layout_marginTop="22dp"
android:max="100"
android:progress="40"
android:secondaryProgress="60" />

<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_customprogressbar4"
android:layout_below="@+id/my_customprogressbar4"
android:layout_marginTop="26dp"
android:max="100"
android:progress="40"
android:secondaryProgress="60" />

</RelativeLayout>

第一种圆形progressbar 仅仅让一个图片旋转起来:

style的代码:

<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的代码:

<?xml version="1.0" encoding="utf-8"?>
<!-- 定义一个旋转的动画 ,图片是我们自定义的-->
<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="360" >

</rotate>

第二种圆形progressbar 使用一个动画:

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的代码:

<?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="250"/>
<item
android:drawable="@drawable/ok2"
android:duration="250"/>
<item
android:drawable="@drawable/ok3"
android:duration="250"/>
<item
android:drawable="@drawable/ok4"
android:duration="250"/>

</animation-list>

第三种圆形progressbar 使用shape来构建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的代码:

<?xml version="1.0" encoding="utf-8"?>
<!-- 定义一个旋转的动画 ,图片是我们自定义的shape -->
<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="#1E90FF"
android:startColor="#000000"
android:type="sweep"
android:useLevel="false" />
</shape>

</rotate>

第四种: 横向progressbar 复制粘贴系统的style,然后修改:

<?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:radius="5dip" />
<gradient
android:startColor="#ffff0000"
android:centerColor="#ffff0000"
android:centerY="0.75"
android:endColor="#ffff0000"
android:angle="270"
/>
</shape>
</item>

<item android:id="@android:id/secondaryProgress">
<clip>
<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#800000ff"
android:centerColor="#800000ff"
android:centerY="0.75"
android:endColor="#800000ff"
android:angle="270"
/>
</shape>
</clip>
</item>

<item android:id="@android:id/progress"
>
<clip >

<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#ff00ff00"
android:centerColor="#ff00ff00"
android:centerY="0.75"
android:endColor="#ff00ff00"
android:angle="270"
/>
</shape>
</clip>
</item>

</layer-list>

这样直接在progressbar中引用该style就可以满足需求了,当然我们也可以把progressbar background progress secondprogress都分别定义成一个drawable,然后使用:

background:

<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<corners android:radius="5dip" />
<gradient
android:angle="270"
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="270"
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="270"
android:centerColor="#800000ff"
android:centerY="0.75"
android:endColor="#800000ff"
android:startColor="#800000ff" />

</shape>

这个时候style中的代码就会清晰一点:

<?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 这个地方原作者写的是一个点9的图-->
<!-- <item android:id="@android:id/progress">
<clip>
<nine-patch android:src="@drawable/progress_patch_galy" />
</clip>
</item>   -->
</layer-list>

对了,代码还是贴上来吧.总感觉在ide中直接看代码会更舒服一些:http://download.csdn.net/detail/u010399316/9000197
