Loading HMOS view lib

Source

This library is inspired by the Cosin library version 1.1.0

Dependency

1. For using Cosin module in sample app, include the source code and add the below dependencies in entry/build.gradle to generate hap/cosin.har.

dependencies {
    implementation project(':cosin')
    implementation fileTree(dir: 'libs', include: ['*.har'])
    testCompile 'junit:junit:4.12'
}

2. For using Cosin in separate application using har file, add the har file in the entry/libs folder and add the dependencies in entry/build.gradle file.

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.har'])
    testCompile 'junit:junit:4.12'
}

3. For using Cosin from a remote repository in separate application, add the below dependencies in entry/build.gradle file.

dependencies {
    implementation 'dev.applibgroup:cosin:1.0.0'
    testCompile 'junit:junit:4.12'
}

Usage

Declaration

<com.nikitagordia.cosin.Cosin
        ohos:height="130vp"
        ohos:width="270px" />

There are 6 default ColorAdapter implementation in box :

• DefaultColorAdapterGb (Green -> Blue)
• ColorAdapterBg (Blue -> Green)
• ColorAdapterBr (Blue -> Red)
• ColorAdapterGr (Green -> Blue)
• ColorAdapterRb (Red -> Blue)
• ColorAdapterRg (Red -> Green)

There are 2 default TextAdapter implementation in box :

• DefaultBinaryTextAdapter (shows random [0, 1] symbols in each rectagle)
• WordTextAdapter (shows specified cycle String)

ColorAdapter overriding example :

public class ColorAdapterBr implements Cosin.ColorAdapter {

    @Override
    public int getBackgroundColor() {
        return Color.TRANSPARENT.getValue();
    }

    @Override
    public int calcColor(int numOfRect, double percentOfHeight) {
        return Color.argb(150, (int) (255 * (1d - percentOfHeight)), 0, (int) (255 * percentOfHeight));
    }
}

TextAdapter overriding example :

public class WordTextAdapter implements Cosin.TextAdapter {
    private String word;

    public WordTextAdapter(String word) {
        this.word = word;
    }

    @Override
    public char getString(int numOfRect) {
        if (word.isEmpty()) {
            return ' ';
        }
        return word.charAt(numOfRect % word.length());
    }
}
