Question

我在面对这样的问题之前实现了数据绑定。但是，这次创造了很多麻烦我无法在我的项目中导入BR。看看我的gradle和代码。

我尝试了stackoverflow answer的所有可能解决方案。

package com.hcl.developer.telematics.Adapter;

import android.databinding.DataBindingUtil;
import android.databinding.ViewDataBinding;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.ViewGroup;

 import com.hcl.developer.telematics.Model.CarResponse;
 import com.hcl.developer.telematics.R;
 import com.hcl.developer.telematics.Utilities.CustomViewHolder;

 import java.util.ArrayList;
  import java.util.List;

/**

 public class CarDetailsAdapter extends RecyclerView.Adapter<CustomViewHolder>
  {

  private List<CarResponse> recentCarRequestList = new ArrayList<>();

public CarDetailsAdapter(List<CarResponse> recentCarRequestList) {
    this.recentCarRequestList = recentCarRequestList;
}

@Override
public CustomViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
    ViewDataBinding binding = DataBindingUtil.inflate(LayoutInflater.from(viewGroup.getContext()), R.layout.history_list_row, viewGroup, false);
    return new CustomViewHolder(binding);
}

@Override
public void onBindViewHolder(CustomViewHolder holder, int position) {
    ViewDataBinding viewDataBinding = holder.getViewDataBinding();
    viewDataBinding.setVariable(BR.car, recentCarRequestList.get(position));

}

@Override
public int getItemCount() {
    return (null != recentCarRequestList ? recentCarRequestList.size() : 0);
}





     }

MyGradle：

apply plugin: 'com.android.application'

android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
    applicationId "com.hcl.developer.telematics"

    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}

dataBinding {
    enabled = true
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }

  androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',

       }

我的XML：

            </LinearLayout>

        </LinearLayout>

    </LinearLayout>


</RelativeLayout>

然后是我的模特课：

  package com.hcl.developer.telematics.Model;

   import android.databinding.BaseObservable;
    import android.databinding.Bindable;

import com.google.gson.annotations.SerializedName;

public class CarResponse extends BaseObservable {

@SerializedName("username")
private String username;

public String getUsername() {
    return username;
}
public void setUsername(String username) {
    this.username = username;
    notifyPropertyChanged(BR.username);
}

         }

检查我的问题：

无法在DataBinding android中解析BR
