1、res---->values文件夾下添加文件attrs.xml詳情如下：

<?xml version="1.0" encoding="utf-8"?> <resources><declare-styleable name="SuccessView"><attr name="svStrokeColor" format="color|reference" /><attr name="svStrokeWidth" format="float" /></declare-styleable></resources>

2、自定義操作成功動畫

3、activity 調用自定義操作成功動畫

?

<com.administrator.tests.MySuccessViewandroid:id="@+id/view"android:layout_width="wrap_content"android:layout_height="wrap_content"app:svStrokeColor="@color/colorPrimary" /> MySuccessView sv =(MySuccessView)findViewById(R.id.view) ; sv.startAnim(200);
