我创建了一个简单的Getter生成器来生成一个“Optional-Getter”，它将字段包装在一个Optional中。问题是当该字段被注释为@Nullable时，getter也将使用@Nullable生成，我发现每次生成getter时简单地删除它非常烦人。我怎样才能忽略costumegetter中的字段注释？这是我的“Optional-Getter”生成器。#if($field.modifierStatic)static###endOptional###set($name=$StringUtil.capitalizeWithJavaBeanConvention($StringUtil

我得到了一个AndroidRoom的实体，看起来像那样。到目前为止，不用担心。@Entity(tableName="users",indices=arrayOf(Index(value="nickName",unique=true)))dataclassUser(@ColumnInfo(name="nickName")varnickName:String,@ColumnInfo(name="password")varpassword:String){@ColumnInfo(name="id")@PrimaryKey(autoGenerate=true)varid:Long=0}现在我需
我有这个方法:publicstaticResponsedeserializeResponse(StringjsonResponse)throwsJsonParseException,JsonMappingException,IOException{ObjectMappermapper=newObjectMapper();try{returnmapper.readValue(jsonResponse,Response.class);}catch(JsonParseExceptione){e.printStackTrace();}catch(JsonMappingExceptione){e
我正在寻找一种简单的方法来为对象设置许多参数并返回对象本身。所以我可以设置任何对象。像这样的东西:publicclassFoo{privateintmValue1;privateStringmValue2;privatebooleanmValue3;privatelongmValue4;publicFoo(){}publicFoosetValue1(intvalue1){mValue1=value1;returnthis;}publicFoosetValue2(Stringvalue2){mValue2=value2;returnthis;}publicFoosetValue3(boo
我使用数据绑定(bind)。有时，当我进行更改时，项目可能会被破坏。然后我转到Build->Cleanproject&Re-Buildproject。我得到了一些奇怪的错误:Unabletodeletefile:{path_to_project}\app\build\intermediates\data_binding_dependency_artifacts\debug\dataBindingMergeDependencyArtifactsDebug\out\androidx.databinding.library.baseAdapters--setter_store.json每次我
假设我有一个自定义的setter方法，我需要两个参数:@BindingAdapter({"imageUrl","placeholder"})publicstaticvoidloadImage(ImageViewimageView,StringimageUrl,Drawabledrawable){Picasso.with(imageView.getContext()).load(imageUrl).placeholder(drawable).into(imageView);}相应的xml是什么样的？ 最佳答案 看起来可以这样做:参见h
不确定它是如何工作的，但根据thispost可以使用不同的命名空间来绑定(bind)特定的监听器。我想对searchview做同样的事情并将QueryTextListener绑定(bind)到它，但我收到以下错误:Cannotfindthesetterforattribute'bind:setOnQueryTextListener'withparametertypeandroid.widget.SearchView.OnQueryTextListener.我在ViewModel中做了什么:publicclassMembersFragmentViewModelextendsBaseObs
如何在Kotlin中使用自定义setter但没有getter来声明属性？在Anko例如他们这样做:varmyProperty:Type@Deprecated(AnkoInternals.NO_GETTER,level=DeprecationLevel.ERROR)get()=AnkoInternals.noGetter()set(value){field=value;/*setterlogic*/}但对我来说它看起来有点hacky。这是正确的方法吗？如果是，那么项目没有Anko依赖的情况呢？附:让我说清楚-我想要根本没有setter/getter，而不是私有(private)sette
