Android利用android:indeterminateDrawable来实现ProgressBar三种方式


方式1:(效果为补间动画一样)



android:layout_width=
    "wrap_content"

  
android:layout_height=
    "wrap_content"


  
android:indeterminate=
    "true"


  
android:indeterminateDrawable=
    "@anim/loading"

其中动画loading:


<?xml version="1.0" encoding="UTF-8"?>

  
<animation-list android:oneshot="false"


  
xmlns:android=
    "http://schemas.android.com/apk/res/android">
   


  
<item android:duration="60" android:drawable="@drawable/load_1"


  
<item android:duration="60" android:drawable="@drawable/load_3"


  
<item android:duration="60" android:drawable="@drawable/load_5"


  
<item android:duration="60" android:drawable="@drawable/load_7"


  
<item android:duration="60" android:drawable="@drawable/load_9"


  
<item android:duration="60" android:drawable="@drawable/load_11"


  
<item android:duration="60" android:drawable="@drawable/load_13"


  
<item android:duration="60" android:drawable="@drawable/load_15"


  
</animation-list>

方式2:(效果为自定义图片让其不断的旋转)

<ProgressBar

  
android:layout_width=
    "wrap_content"


  
android:layout_height=
    "wrap_content"


  
android:indeterminate=
    "true"


  
android:indeterminateDrawable=
    "@drawable/progressbar"

其中progressbar:

<?xml version="1.0" encoding="utf-8"?>

  
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"


  
 
   


  
<item>


  
<rotate


  
android:drawable=
    "@drawable/load"


  
android:fromDegrees=
    "0.0"


  
android:pivotX=
    "50.0%"


  
android:pivotY=
    "50.0%"


  
android:toDegrees=
    "360.0"


  
<span style="white-space:pre"> 
    </span> 
    <!-- 其中360.0值越大,转的圈圈越快 -->


  
</item>
</layer-list>


方式三:(效果为自定义颜色让其不断的旋转)

<ProgressBar

  
android:layout_width=
    "wrap_content"


  
android:layout_height=
    "wrap_content"


  
android:indeterminate=
    "true"


  
android:indeterminateDrawable=
    "@drawable/progressbar2"

其中progressbar2:

<pre name="code" class="html">
    <?xml version="1.0" encoding="utf-8"?>

  
<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"
