Gradle 使用自定义 XML 标记和数据绑定构建不成功

Question

当我尝试运行使用数据绑定和绑定布局中的自定义 XML 标记的项目时，我遇到了下面描述的构建错误：

布局：

<data>
   <variable
        name="data"
        type="com.melontech.sff.viewmodel.DataViewModel" />
</data> 

...

<ImageView 
   android:id="@+id/image"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:src="@mipmap/placeholder_img"
   app:imageUrl="@{data.imageUrl}" />

...

视图模型具有以下绑定适配器：

@BindingAdapter("bind:imageUrl")
public static void getImageUrl(ImageView imageView, String url) {
    Timber.d("LOAD IMAGE WITH URL %s", url);
}

创建 ViewHolder 并进行绑定的代码如下：

@Override
public ModelViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    ModelListItemBinding binding = DataBindingUtil.inflate(LayoutInflater.from(parent.getContext()), R.layout.model_list_item, parent, false);
    return new ModelViewHolder(binding);
}

构建错误：

Error:Execution failed for task ':app:transformJackWithJackForDebug'.

Gradle 文件中启用了数据绑定。

如果我将此功能移动到一个单独的干净项目中并像这样绑定数据：

ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main);

自定义 XML 属性按预期工作并且构建成功。

您知道构建错误的原因吗？

Answer 1

试试这个方法...

@BindingAdapter("imageUrl")
public static void getImageUrl(ImageView imageView, String url) {
    Timber.d("LOAD IMAGE WITH URL %s", url);
}


<ImageView 
   android:id="@+id/image"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:src="@mipmap/placeholder_img"
   tools:imageUrl="@{data.imageUrl}" />

Answer 2

Jd Prajapati 这是我的 ViewModel class:

public class DataViewModel {

   private Data data;

   public DataViewModel() {
   }

   public DataViewModel(Data data) {
       this.data = data;
   }

   public Data getData() {
       return data;
   }

   public void setData(Data data) {
       this.data = data;
   }

   public String getTitle() {
       if (data != null) {
           if (!TextUtils.isEmpty(data.getTitle())) {
               return data.getTitle();
           }
       }
       //Case when title doesn't exist
       return "";
   }

   public String getImageUrl() {
       if (data != null) {
           if (!TextUtils.isEmpty(data.getMainPic())) {
               return data.getMainPic();
           }
       }
       //Case when poster url doesn't exist
       return "";
   }

   @BindingAdapter("imageUrl")
   public static void getImageUrl(ImageView imageView, String url) {
        Timber.d("LOAD IMAGE WITH URL %s", url);
   }
}

顺便说一句，我找到了一种通过将 ImageView 属性更改为以下内容来使 Gradle 构建项目的方法：

<ImageView
   android:id="@+id/movie_poster"
   android:layout_width="@dimen/dim_160dp"
   android:layout_height="@dimen/dim_240dp"
   android:src="@mipmap/movie_placeholder_img"
   app:imageUrl="@{singleMovie.getImageUrl()}" />

Answer 3

我遇到了和你一样的问题。但是我找到了绑定的解决方案，而不是直接调用 getImageUrl。

<ImageView 
   android:id="@+id/image"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:src="@mipmap/placeholder_img"
   app:imageUrl="@{data.imageUrl}" />
@BindingAdapter("bind:imageUrl")
public static void getImageUrl(ImageView imageView, Object url) {
    Timber.d("LOAD IMAGE WITH URL %s", (String) url);
}

使用对象而不是字符串。然后它会起作用。可能是绑定或插孔的错误。

Answer 4

我认为您正在尝试同时使用 Java 8 功能和 Data Binding。当您添加

 compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

和Jack Compiler

jackOptions {
            enabled true
        }

对于您的项目，您遇到了自定义属性错误。

Google 说：

The Jack toolchain is deprecated, as per this announcement. If your project depends on Jack, you can keep using it. However, it may be removed completely in a future preview release of Android Studio 2.4. So we recommend disabling Jack and using Java 8 support built into Android Studio’s default toolchain.

官方文档如下： https://developer.android.com/studio/preview/features/java8-support.html

如果您只是将它用于 RetroLambda，您可以像下面那样迁移它而无需启用 Jack。

buildscript {
  ...
   dependencies {
      // Remove the following dependency.
      classpath 'me.tatarka:gradle-retrolambda:<version_number>'
   }
}

并且在您的应用程序中 gradle：

apply plugin: 'me.tatarka.retrolambda'

还有第二种方式； - 正如 Seto 提到的那样 - 您可以像下面的代码一样更改您的 Binding Adapter：

@BindingAdapter("imageUrl")
public static void getImageUrl(ImageView imageView, Object url) {
    Timber.d("LOAD IMAGE WITH URL %s", (String)url);
}

这也适用于您。祝你好运。
