一、通过动画实现
定义res/anim/loading.xml如下:
[java] view plaincopy
- <?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文件中引用如下:
[java] view plaincopy
- <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" />
二、通过自定义颜色实现
定义res/drawable/dialog_style_xml_color.xml如下:
[java] view plaincopy
- <?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文件中引用如下:
[java] view plaincopy
- <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" />
三、使用一张图片进行自定义
定义res/drawable/dialog_style_xml_icon.xml如下:
[java] view plaincopy
- <?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>
在layout文件中引用如下:
[html] view plaincopy
- <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_icon" />
main.xml如下:
[html] view plaincopy
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:orientation="vertical" android:layout_width="fill_parent"
- android:layout_height="fill_parent" android:gravity="center"
- android:background="#FFF">
- <Button android:text="@string/anim" android:id="@+id/anim"
- android:layout_width="120dip" android:layout_height="wrap_content" />
- <Button android:text="@string/color" android:id="@+id/color"
- android:layout_width="120dip" android:layout_height="wrap_content" />
- <Button android:text="@string/icon" android:id="@+id/icon"
- android:layout_width="120dip" android:layout_height="wrap_content" />
- </LinearLayout>
之后通过三个按钮将ProgressBar 放在对话框中显示出来就完成了。
