ObservableInt 导致 DataBinding 库崩溃答案

【问题标题】：ObservableInt causes crash on DataBinding LibraryObservableInt 导致 DataBinding 库崩溃
【发布时间】：2015-06-08 13:11:50
【问题描述】：

我正在使用新的数据绑定库并尝试实现可观察接口。但无论我是否将年龄变量设置为 textview，它都会崩溃。如果我将年龄变量转换为字符串，代码工作正常。有没有办法让它与 int 一起工作？

public class User extends BaseObservable {

@Bindable
public final ObservableField<String> name =
        new ObservableField<>();
@Bindable
public final ObservableInt age = new ObservableInt();}

崩溃日志：

【问题讨论】：

标签： android data-binding

【解决方案1】：

把这个放在数据标签里

您需要在 TextView 中使用 @{String.valueOf(user.age)}。

或@{""+user.age}

【讨论】：

谢谢。我会接受你的答案，但 @{Integer.valueOf(user.age)} 返回 ınteger 所以它再次崩溃..我会编辑你的答案 android:text="@{String.valueOf(user.age)}"跨度>
我可以确认String.valueOf() 有效。我花了太长时间试图让绑定正常工作。
