它显示错误不是抽象的，并且不会覆盖 OnClickListener 中的抽象方法 onClick(View)

Question

请帮帮我！我正在尝试在井字游戏中添加音效，但遇到了这个错误。

MainActivity.java:32：错误： 不是抽象的，并且不会覆盖 OnClickListener 中的抽象方法 onClick(View) button_00.setOnClickListener(new View.OnClickListener() { ^

package com.example.tictactoe;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Context;
import android.media.MediaPlayer;
import android.view.View.OnClickListener;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    private Button[][] buttons = new Button[3][3];
    private boolean player1Turn = true;
    private int roundCount;
    private int player1Points;
    private int player2Points;
    private TextView textViewPlayer1;
    private TextView textViewPlayer2;
    MediaPlayer mp;
    Context context = this;
    Button button_00;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button_00 = (Button) findViewById(R.id.button_00);
        final MediaPlayer mp = MediaPlayer.create(this, R.raw.sample);
        button_00.setOnClickListener(new View.OnClickListener() {
            public void onCLick(View v) {
                mp.start();
            }
        });

你的代码

button_00.setOnClickListener(new View.OnClickListener() {
**@Override**(this is missing in ur code)
public void onC**L**(capital `L` it should be small)ick(View v) {
mp.start();
}
});

更新代码

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    private Button[][] buttons = new Button[3][3];
    private boolean player1Turn = true;
    private int roundCount;
    private int player1Points;
    private int player2Points;
    private TextView textViewPlayer1;
    private TextView textViewPlayer2;
    MediaPlayer mp;
    Context context = this;
    Button button_00;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button_00 = (Button) findViewById(R.id.button_00);
        final MediaPlayer mp = MediaPlayer.create(this, R.raw.sample);
        button_00.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mp.start();

            }
            
        });
