错误:找不到符号类DataBindingComponent

我下载了一个Android项目,但是我收到了这个错误:

Error:(42, 42) error: cannot find symbol class DataBindingComponent

样品导入:

import android.databinding.DataBindingComponent; // no code-time error
import android.databinding.DataBindingUtil;
import android.databinding.ViewDataBinding;

样品用法:

public FragmentFantasyPointsSingleBinding(DataBindingComponent bindingComponent, View root) {
        super(bindingComponent, root, 0);
        Object[] bindings = ViewDataBinding.mapBindings(bindingComponent, root, 4, sIncludes, sViewsWithIds);
        this.animatiOnView= (LottieAnimationView) bindings[3];
        this.mboundView0 = (FrameLayout) bindings[0];
        this.mboundView0.setTag(null);
        this.progressView = (LinearLayout) bindings[2];
        this.recyclerView = (RecyclerView) bindings[1];
        setRootTag(root);
        invalidateAll();
    }

代码时间没有错误,但在编译时我得到了我提到的错误.

当我尝试在Android Studio上进行定义时,我不能.

应用程序级build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.esports.flank"
        minSdkVersion 19

    }
    dataBinding {
        enabled = true
    }
}

我试过清理和重建项目,但没有运气.

感谢帮助.

这个答案在类似的情况下帮助了我:https://stackoverflow.com/a/52550118/8655667

添加线条 android.enableExperimentalFeatureDatabinding=true和android.databinding.enableV2=false以gradle.properties

同步项目

建立 - >清洁项目

构建 - >重建项目

重建后它应该给你实际的编译失败原因.
