水波紋+仿探探卡片滑動+飄贊動畫

本篇文章主要記錄一下開發過程通過網上搜索和本項目需求結合最終實現效果做個記錄，
本人比較賴，就不抽demo了，關鍵代碼已貼，仿探探卡片相關文件附git 下載鏈接，避免以後再各種搜索
附上最終效果圖

一、水波紋

        app:waveSpeed="7"
        app:waveStrokeWidth="3dp" />

	//初始化開啓
     waveView.start();//開啓水波紋

   @Override
    public void onDestroy() {
        super.onDestroy();
        waveView.stop();
    }
