android 自己定义水平和圆形progressbar 仅仅定义一些style就能够
效果图:
改动progressbar 让他满足自己的需求一般来说仅仅改动一下,progressbar的style就能够满足需求了:
activity代码:只显示一个布局而已
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 只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 ,图片是我们自己定义的--> <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>
另外一种圆形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 ,图片是我们自己定义的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,然后改动:
<?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就能够满足需求了,当然我们也能够把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>
嘿嘿..最后,做人要厚道:神一般男人的原博主博文连接http://blog.csdn.net/mad1989/article/details/38042875
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
