无法准确地从RxJava2迁移到RxJava3。

Question

尽管我已经升级了依赖关系，但还是无法将该方法转换为RxJava3。

fun setSearchField(searchField: EditText) {
        searchDisposable = searchField.afterTextChangeEvents()
            .skipInitialValue()
            .debounce(400, TimeUnit.MILLISECONDS)
            .map { it.editable()?.toString() ?: "" }
            .distinctUntilChanged()
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(::onSearchQueryUpdated)
    }

类型不匹配.必填:io.reactivex.rxjava3.disposables.Disposable?找到:io.reactivex.disposables.Disposable!

    def retrofit_version = '2.9.0'
    implementation "io.reactivex.rxjava3:rxjava:3.0.4"
    implementation "io.reactivex.rxjava3:rxkotlin:3.0.0"
    implementation "io.reactivex.rxjava3:rxandroid:3.0.0"
    implementation "com.jakewharton.rxbinding3:rxbinding:3.1.0"
    implementation "com.squareup.retrofit2:retrofit:$retrofit_version"
    implementation "com.squareup.retrofit2:converter-gson:$retrofit_version"
    implementation "com.github.akarnokd:rxjava3-retrofit-adapter:3.0.0"
    implementation "com.squareup.okhttp3:logging-interceptor:4.7.2"

我应该如何准确清理RxJava2的项目？

我试过Invalidate cachesRestart：什么都没发生。

你看，那个rxbinding3有一个转折性的依赖关系到

|    +--- io.reactivex.rxjava2:rxjava:2.2.10

覆盖RxJava3

解决办法：

implementation 'com.jakewharton.rxbinding4:rxbinding:4.0.0'
