如何在mainactivity中编写多个按钮而不出错？

public class MainActivity extends AppCompatActivity {
    private Button button1;
    private Button button2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 初始化按钮控件
        button1 = findViewById(R.id.button1);
        button2 = findViewById(R.id.button2);

        // 设置按钮点击事件监听器
        button1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 按钮1的点击逻辑
                Toast.makeText(MainActivity.this, "按钮1被点击了", Toast.LENGTH_SHORT).show();
            }
        });

        button2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 按钮2的点击逻辑
                Toast.makeText(MainActivity.this, "按钮2被点击了", Toast.LENGTH_SHORT).show();
            }
        });
    }
}
