复现：随便选择一个颜色（除默认的灰色），旋转屏幕

原因分析：修改颜色后旋屏会调用 setWaveColor()，此时height和width都为 0
不知道为什么会调用 setWaveColor()？

暂时解决： 在 createShader() 中添加如下代码

if (getHeight() == 0) {
            return;
}

In my simulator(1080*1920,API 19),there is a white vertical line in the wave, and I have find the solution:In WaveView.java -> createShader ,change from final float endX = getWidth(); to final float endX = getWidth()+1;

在线等，谢谢

我这边的需求是没有边框的，我在布局中设置了match_parent，也通过seekbar 将边框设置最小，可是还是不能填充完空间，请问有什么好办法么? 是需要我自己重写onmeause()?

Is there any way we can add Bubbles in the Wave.
We wanted to have Beer effect. So any ideas will be helpful.

I want to call some action when wave has covered my screen while holding an button, i implement the motion event action up and down as well.
Actually,
When the wave covers my screen fully and i release that button,action up called for that button and
i check the

Recently I use this library and thanks very much , but it costs CPU a lot , any way to optimize it?

I want to set WaveView opaque.
I have set up the Alpha of wavePaint1 to 255.
But no matter what i do, View is still transparent.
Do you have some good method?

Like this(the red view should be opaque).

Hello,

We are currently using your library in one of our applications. Actually we need a favour from your side. According to the Google Play Policy, all apps have to provide support for at least API level 26. It seems like yours is not as per the new Google Play Policy. We are targeting API level 28. So can you please provide us support for API level 28 in your current repository?

java.lang.IllegalArgumentException: width and height must be > 0 in wave annimation

Causing crash with devices below 5.1

I am trying to use the library in conjunction with the gyroscope values so that when I rotate the phone, I get the water flowing effect.

The only problem is, when the WaveView rotates, it doesn't expand it's height and width to fill the blank area that's generated in the sides.
This happens even if I have given match_parent as the width.

Is there a way to get this working?
Or am I getting something wrong?

I have put a stackoverflow question too, with images, here : https://stackoverflow.com/q/48369005/7947474

如果放到bitmap上面去画的话，属性动画位移的时候，会有颜色位移的色带。如果是放到onDraw里面的话，就会出现断层的问题，我是drawArc，麻烦指点一二，谢谢
