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>
