进度条默认是不确定（indeterminate=true）Android进度条
Android进度条有4种风格可以使用。
默认值是progressBarStyle。
设置成progressBarStyleSmall后，图标变小。
设置成progressBarStyleLarge后，图标变大
设置成progressBarStyleHorizontal后，变成横向长方形。
自定义圆形进度条ProgressBar的一般有三种方式:
一、通过动画实现
定义res/anim/loading_anim.xml如下:
1
|
<?xml version="1.0" encoding="utf-8"?>
|
2
|
<animation-list android:oneshot="false"
|
4
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f0" />
|
5
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f1" />
|
6
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f2" />
|
7
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f3" />
|
8
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f4" />
|
9
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f5" />
|
10
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f6" />
|
11
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f7" />
|
12
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f8" />
|
13
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f9" />
|
14
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f10" />
|
15
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f11" />
|
16
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f12" />
|
17
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f13" />
|
18
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f14" />
|
19
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f15" />
|
20
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f16" />
|
21
|
<item android:duration="150" android:drawable="@drawable/loading_blue_16_f17" />
|
在layout文件中引用如下：
2
|
android:id="@+id/progressBar1"
|
3
|
android:layout_width="wrap_content"
|
4
|
android:layout_height="wrap_content"
|
5
|
android:layout_gravity="center_horizontal"
|
6
|
android:layout_marginBottom="20dip"
|
7
|
android:layout_marginTop="20dip"
|
8
|
android:indeterminate="false"
|
9
|
android:indeterminateDrawable="@anim/loading_anim" />
|
二、通过自定义颜色实现
定义res/drawable/loading_color.xml如下：
1
|
<?xml version="1.0" encoding="utf-8"?>
|
3
|
android:fromDegrees="0"
|
6
|
android:toDegrees="360" >
|
8
|
android:innerRadiusRatio="3"
|
10
|
android:thicknessRatio="8"
|
11
|
android:useLevel="false" >
|
13
|
android:centerColor="#FFDC35"
|
14
|
android:centerY="0.50"
|
15
|
android:endColor="#CE0000"
|
16
|
android:startColor="#FFFFFF"
|
18
|
android:useLevel="false" />
|
在layout文件中引用如下：
2
|
android:id="@+id/progressBar2"
|
3
|
android:layout_width="wrap_content"
|
4
|
android:layout_height="wrap_content"
|
5
|
android:indeterminate="false"
|
6
|
android:indeterminateDrawable="@drawable/loading_color" />
|
三、使用一张图片进行自定义
定义res/drawable/loading_img.xml如下：
1
|
<?xml version="1.0" encoding="utf-8"?>
|
5
|
android:drawable="@drawable/exchange_loading"
|
6
|
android:fromDegrees="0.0"
|
9
|
android:toDegrees="360.0" />
|
在layout文件中引用如下：
2
|
android:id="@+id/progressBar3"
|
3
|
android:layout_width="wrap_content"
|
4
|
android:layout_height="wrap_content"
|
5
|
android:indeterminate="false"
|
6
|
android:indeterminateDrawable="@drawable/lodaing_img"
