Integration

implementation 'com.gelitenight.waveview:waveview:1.0.0'

Setter methods:

  • setWaveShiftRatio - Shift the wave horizontally.
  • setWaterLevelRatio - Set water level.
  • setAmplitudeRatio - Set vertical size of wave.
  • setWaveLengthRatio - Set horizontal size of wave.

You can use Property Animation to animate WaveView.

// horizontal animation.
// wave waves infinitely.
ObjectAnimator waveShiftAnim = ObjectAnimator.ofFloat(
        mWaveView, "waveShiftRatio", 0f, 1f);
waveShiftAnim.setRepeatCount(ValueAnimator.INFINITE);
waveShiftAnim.setDuration(1000);
waveShiftAnim.setInterpolator(new LinearInterpolator());

// vertical animation.
// water level increases from 0 to center of WaveView
ObjectAnimator waterLevelAnim = ObjectAnimator.ofFloat(
        mWaveView, "waterLevelRatio", 0f, 0.5f);
waterLevelAnim.setDuration(10000);
waterLevelAnim.setInterpolator(new DecelerateInterpolator());
animators.add(waterLevelAnim);

// amplitude animation.
// wave grows big then grows small, repeatedly
ObjectAnimator amplitudeAnim = ObjectAnimator.ofFloat(
        mWaveView, "amplitudeRatio", 0f, 0.05f);
amplitudeAnim.setRepeatCount(ValueAnimator.INFINITE);
amplitudeAnim.setRepeatMode(ValueAnimator.REVERSE);
amplitudeAnim.setDuration(5000);
amplitudeAnim.setInterpolator(new LinearInterpolator());
animators.add(amplitudeAnim);

    Why can't I set WaveView opaque?

    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). image

  • 选择颜色,然后旋转屏幕会crash

    选择颜色,然后旋转屏幕会crash

    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heightwidth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;
    }

  • Support for latest API level

    Support for latest API level

    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?

  • Making the WaveView fill the remaining space after rotation is not working

    Making the WaveView fill the remaining space after rotation is not working

    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
