A bar chart loading view that you can specify the number of bars.
Add it in your root build.gradle at the end of repositories：
allprojects {
repositories {
//...
maven { url 'https://jitpack.io' }
}
}Add it in your app build.gradle at the end of repositories:
dependencies {
implementation 'com.github.samlss:BarChartLoadingView:1.0'
}in layout.xml：
<com.iigo.library.BarChartLoadingView
android:id="@+id/bclv_loading1"
app:barNumber="4"
android:layout_centerInParent="true"
android:layout_width="100dp"
android:layout_height="100dp" />in java code：
barChartLoadingView.setBarNumber(6); //set bar number
barChartLoadingView.setColorSchemeColors(new int[]{Color.RED, Color.GREEN, Color.BLUE, Color.MAGENTA, Color.GRAY, Color.YELLOW}); //set the color array
barChartLoadingView.start(); //start animation
barChartLoadingView.stop(); //stop animation
barChartLoadingView.release(); //release when you do net need the view anyway.About the setColorSchemeColors method:
I will use the following code as an example:
barChartLoadingView.setColorSchemeColors(new int[]{
Color.parseColor("#F47E60"), //color1
Color.parseColor("#E15B64"), //color2
Color.parseColor("#ABBD81"), //color3
Color.parseColor("#F8B26A"), //color4
});
For each bar, the color of the corresponding color array subscript is set according to the set color array. If the number of bars exceeds the size of the color array, the color setting is performed by taking the color array as the remainder.
Attributes description：
| attr | description |

| barNumber | specify how many bars you want to set |
I don't limit the number of bars (the default number is 4). When you set the barNumber, you should combine the actual quantity requirements and performance impact to set a suitable number.
In addition, if you need to set the relevant properties of the bar animation, you can modify it by downloading the source code.
valueAnimator.setStartDelay(startDelay);
At present, the bars animation is to make the visual animated irregularity by setting different random startDelay values, so it is possible that the startDelay values are very close, resulting in a very small irregularity gap. If you need more accurate irregularity animation, you can customize it by downloading source code.
