在CustomView中扩展ArrayAdapter时，在Android中将Kotlin转换为Java

package com.example.myapplication

import android.content.Context
import android.util.AttributeSet
import android.view.View

class CustomView @JvmOverloads constructor(
    context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : View(context, attrs, defStyleAttr) {

    fun doSomething() {
        // 执行某些操作
    }

    companion object {
        const val DEFAULT_VALUE = 0
    }
}

package com.example.myapplication;

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;

public class CustomView extends View {

    public CustomView(Context context) {
        super(context);
    }

    public CustomView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public void doSomething() {
        // 执行某些操作
    }

    public static final int DEFAULT_VALUE = 0;
}
