Question

我在TextBoxBinding.java中得到以下错误

// Generated by view binder compiler. Do not edit!
package com.example.verzeo_one.databinding;

import android.view.LayoutInflater;

import com.example.verzeo_one.R;
import java.lang.NullPointerException;
import java.lang.Override;

public final class TextboxBinding implements ViewBinding {
  @NonNull
  private final shape rootView;

  private TextboxBinding(@NonNull shape rootView) {
    this.rootView = rootView;
  }

  @Override
  @NonNull
  public shape getRoot() {
    return rootView;
  }

  @NonNull
  public static TextboxBinding inflate(@NonNull LayoutInflater inflater) {
    return inflate(inflater, null, false);
  }

  @NonNull
  public static TextboxBinding inflate(@NonNull LayoutInflater inflater, @Nullable ViewGroup parent,
      boolean attachToParent) {
    View root = inflater.inflate(R.layout.textbox, parent, false);
    if (attachToParent) {
      parent.addView(root);
    }
    return bind(root);
  }

  @NonNull
  public static TextboxBinding bind(@NonNull View rootView) {
    if (rootView == null) {
      throw new NullPointerException("rootView");
    }

    return new TextboxBinding((shape) rootView);
  }
}

</shape>

Answer 1

可能是因为android.widget.shape不是shape类的来源，所以出现了这个错误。

查看官方文档，正确的命名空间似乎是Android.graphics.drawable.shapes.shape。Android.widget包根本没有列出任何名为shape的类。
