【问题描述】:
在app/build.gradle:
dataBinding {
enabled = true
}
kapt "com.android.databinding:compiler:3.0.1"
在布局中我有两个图像。
我想仅为第一张图片设置宽度。
这是 XML 布局:
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<data>
<import type="com.myproject.android.customer.util.GuiUtil" />
</data>
<ImageView
android:id="@+id/imageViewPhoto"
android:layout_width="@{GuiUtil.getTileWidthDpInScreen(context), default=@dimen/preview_image_height}"
android:layout_height="@dimen/preview_image_height"/>
<ImageView
android:id="@+id/imageViewFavorite"
android:layout_width="28dp"
android:layout_height="28dp"/>
</layout>
这是适配器的代码:
@BindingAdapter("layout_width")
public static void setLayoutWidth(View view, int width) {
ViewGroup.LayoutParams layoutParams = view.getLayoutParams();
layoutParams.width = width;
view.setLayoutParams(layoutParams);
}
这里是GuiUtil.getTileWidthDpInScreen的方法:
public class GuiUtil {
public static int getTileWidthDpInScreen(Context context) {
// some logic that return int value
}
但我收到此错误:
:app:transformDataBindingWithDataBindingMergeArtifactsForDebug UP-TO-DATE
:app:kaptDebugKotlin
