将 ContainsFunction的call函数改为以下内容 修复bug

public class ContainsFunction implements FilterFunction {
public Object call(ViewImage element, List params) {
boolean isContains = false;
if (params.get(0).calc(element) != null) {
isContains = params.get(0).calc(element).toString().contains(params.get(1).calc(element).toString());
}
return isContains;
}

public String getName() {
    return "contains";
}

}
