自定义类，还不是很完善，有需要的可以参考一下。

使用：

        waveProgressbar = (LWaveLoadingView) findViewById(R.id.wave_progressbar);waveProgressbar.setCurrent(0, progress + "%"); // 77, "788M/1024M"waveProgressbar.setMaxProgress(100);waveProgressbar.setText("#66FF00FF", 31);//"#FFFF00", 41waveProgressbar.setWaveColor("#550a40dd"); //"#5b9ef4"waveProgressbar.setWave(5, 30);//水波纹振幅和周期长度waveProgressbar.setmWaveSpeed(10);//值越大 水波移动越慢
