android 自訂 菊花，android自訂菊花

1.通過幀動畫實現

   定義res/anim/loading.xml如下：
<?xml version="1.0" encoding="UTF-8"?>
<animation-list android:oneshot="false"
  xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:duration="150" android:drawable="@drawable/loading_01" />
  <item android:duration="150" android:drawable="@drawable/loading_02" />
  <item android:duration="150" android:drawable="@drawable/loading_03" />
  <item android:duration="150" android:drawable="@drawable/loading_04" />
  <item android:duration="150" android:drawable="@drawable/loading_05" />
  <item android:duration="150" android:drawable="@drawable/loading_06" />
  <item android:duration="150" android:drawable="@drawable/loading_07" />
</animation-list>

  在layout檔案中引用如下：
<ProgressBar android:id="@+id/loading_process_dialog_progressBar"
  android:layout_width="wrap_content" android:layout_height="wrap_content"
  android:indeterminate="false" android:indeterminateDrawable="@anim/loading" />

2.通過自訂色彩實現

定義res/drawable/dialog_style_xml_color.xml如下：
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:pivotX="50%" android:pivotY="50%" android:fromDegrees="0"
android:toDegrees="360">
<shape android:shape="ring" android:innerRadiusRatio="3"
  android:thicknessRatio="8" android:useLevel="false">
  <gradient android:type="sweep" android:useLevel="false"
   android:startColor="#FFFFFF" android:centerColor="#FFDC35"
   android:centerY="0.50" android:endColor="#CE0000" />
</shape>
</rotate>

在layout檔案中引用如下：
<ProgressBar android:id="@+id/loading_process_dialog_progressBar"
  android:layout_width="wrap_content" android:layout_height="wrap_content"
  android:indeterminate="false" android:indeterminateDrawable="@drawable/dialog_style_xml_color" />

3.通過使用旋轉一張圖片定義實現

定義res/drawable/dialog_style_xml_icon.xml如下：
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
  <rotate android:drawable="@drawable/dialog_progress_round"
   android:fromDegrees="0.0" android:toDegrees="360.0" android:pivotX="50.0%"
   android:pivotY="50.0%" />
</item>
</layer-list>
