Checking the code, found out this: long gap = 16 - System.currentTimeMillis() - start; File: Wave.java -- Class: RefreshProgressRunnable i am always getting negative values...why not make it: long gap = 16 - (System.currentTimeMillis() - start); so it gets a positive number always and we can delete gap < 0 ? 0 : gap check?

Hello there,

I forked your great project to make it easier to implement with gradle. You can check it out from here

Thanks again for perfect library. Good luck.

After a long time, the phone gets hot and the monitor in AS tells the cpu usage is around 30%(for only one view, about 60% for two view) ? Anyone met the problem?

• Users can apply background color, wave filling's color and alpha declaratively (XML) or programatically. [#6,#23]

• Users can alter above and below wave's color and alpha. [#23]

<com.john.waveview.WaveView
        android:id="@+id/wave_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#FFFFFF"
        wave:above_wave_color="@color/dark_blue"

        wave:wave_hz="normal"
        wave:wave_length="middle" 
        wave:wave_color="@color/holo_purple"
        wave:wave_alpha="0.5"/>

        waveView.setAboveWaveColor(color);
        waveView.setBlowWaveColor(color);
        waveView.setWaveColor(color);
        waveView.setWaveAlpha(0.5f);
        waveView.setAboveWaveColorAlpha(0.3f);
        waveView.setBlowWaveColorAlpha(0.3f);

• Made default above and below wave color to be that of the actual wave color, instead of white color.
• Users can make the wave color to be their gradient color. [#24]

....
wave:background="@drawable/gradient_background"/>

waveView.setWaveBackgroundDrawable(getResources().getDrawable(R.drawable.gradient_background));

• Allows users to let the view fill to the brim on their discretion via the newly created boolean attribute: fill_to_brim.

. . .
wave:wave_length="middle"
wave:fill_to_brim="true" />

• Includes only Gradle update and README Badge fix done in #25. Note: It does not consider the feature implemented in #25.

• README sample code update based on this feature.

• Users can change wave speed manually; Any value [0,1]. This will give them more control on the speed of the wave. Example of using custom hz value for wave:

Users simply have to set the newly altered attribute wave_hz:

wave:wave_hz="0.09"
wave:fill_to_brim="true" />

• Upgraded Gradle plugin version to 4.11 and Gradle version to 6.5 While running on Android Studio IDE 4.1.1,a prompt to upgrade Gradle appeared"Support for builds using Gradle versions older than 2.6 was removed in tooling API version 5.0. You are currently using Gradle version 2.2. You should upgrade your Gradle build to use Gradle 2.6 or later."

• Updated and fixed minor issue regarding badge in README:

• Added public getter for progess (#21)

Is there a scope of the library being updated to support gradient fills? In order to support a subtle effect like the following (I am referring to the background alone, ignore the dark objects on each image) It's a part of an app I am working on that has millions of downloads, and would thus impact a huge audience.
