You can use this library in your java project with 100% java interoperability in Kotlin

for example

SnapTimePickerDialog dialog = new SnapTimePickerDialog.Builder()
        .setTitle(/* ... */)
        .setPrefix(/* ... */)
        .setSuffix(/* ... */)
        .setThemeColor(/* ... */)
        .setTitleColor(/* ... */)
        .build();
dialog.show(getSupportFragmentManager(), /* ... */);
