android 自己定義水平和圓形progressbar 僅僅定義一些style就能夠

效果圖:

改動progressbar 讓他滿足自己的需求一般來說僅僅改動一下,progressbar的style就能夠滿足需求了:

activity代碼:只顯示一個布局而已

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>

第一種圓形progressbar 只讓一個圖片旋轉起來:

style的代碼:

 <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的代碼:

<?
xml version="1.0" encoding="utf-8"?>
<!-- 定義一個旋轉的動畫 ,圖片是我們自己定義的-->
<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>

另外一種圓形progressbar 使用一個動畫:

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的代碼:

<?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>

第三種圓形progressbar 使用shape來構建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的代碼:

<?xml version="1.0" encoding="utf-8"?>
<!-- 定義一個旋轉的動畫 ,圖片是我們自己定義的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>

第四種: 橫向progressbar 復制粘貼系統的style,然后改動:

<?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>

這樣直接在progressbar中引用該style就能夠滿足需求了,當然我們也能夠把progressbar background progress secondprogress都分別定義成一個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>

這個時候style中的代碼就會清晰一點:

<?
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 這個地方原作者寫的是一個點9的圖-->  
    <!-- <item android:id="@android:id/progress">  
        <clip>  
            <nine-patch android:src="@drawable/progress_patch_galy" />  
        </clip>  
    </item>   -->
</layer-list>

對了,代碼還是貼上來吧.總感覺在ide中直接看代碼會更舒服一些:http://download.csdn.net/detail/u010399316/9000197
