Examples with Nullable androidx.annotation.Nullable used on opensource projects

Example 1 with Nullable

use of androidx.annotation.Nullable in project butterknife by JakeWharton.

the class ButterKnife method parseBindDimen.

@Nullable
private static Unbinder parseBindDimen(Object target, Field field, View source) {
    BindDimen bindDimen = field.getAnnotation(BindDimen.class);
    if (bindDimen == null) {
        return null;
    }
    validateMember(field);
    int id = bindDimen.value();
    Resources resources = source.getContext().getResources();
    Class<?> fieldType = field.getType();
    Object value;
    if (fieldType == int.class) {
        value = resources.getDimensionPixelSize(id);
    } else if (fieldType == float.class) {
        value = resources.getDimension(id);
    } else {
        throw new IllegalStateException("@BindDimen field type must be 'int' or 'float'. (" + field.getDeclaringClass().getName() + '.' + field.getName() + ')');
    }
    trySet(field, target, value);
    return Unbinder.EMPTY;
}
