Question

使用android datat绑定librery时出现错误我已经成功完成了一种可行的布局。但是我创建了新的布局，并在新的<layout>和.xml中添加了Build->clean project标签，但出现了错误

* What went wrong:  Execution failed for task ':app:mergeDebugResources'.> Error: java.lang.ArrayIndexOutOfBoundsException

我的build.gradle模块级别

apply plugin: 'com.android.application'

    compileSdkVersion 27

IMainActivity 公用接口IMainActivity {

void inflateQuantityDialog();

void setQuantity(int quantity);

void addToCart();

}

这段代码一切正常，我只是创建.xml文件并添加<layout>标签和cleab项目，发生错误。

<?xml version="1.0" encoding="utf-8"?>
    <layout>

  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="170dp"
    android:layout_height="wrap_content"
    android:background="@drawable/grey_rounded_background">

    <RelativeLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:orientation="horizontal"
      android:background="@drawable/grey_rounded_button"
      android:padding="5dp">

      <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="16sp"
        android:textColor="@color/Black"
        android:textStyle="bold"
        android:text="@string/dialog_quantity_title"
        android:layout_centerVertical="true"
        android:layout_marginLeft="10dp" />
   </RelativeLayout>
  </LinearLayout>
</layout>
