代码：

package com.example.myapplication;
    
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.View;
    
    import androidx.appcompat.app.AppCompatActivity;
    
    
    public class MainActivity extends AppCompatActivity implements View.OnClickListener
    {
    
        @Override
        protected void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
    
            findViewById(R.id.btn_next).setOnClickListener(this);
        }
    
        @Override
        public void onClick(View v)
        {
            if (v.getId() == R.id.btn_next)
            {
                Intent intent = new Intent(this, NextActivity.class);
                startActivity(intent);
    
            }
        }
    
    
    }

也可以：

package com.example.myapplication;
    
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.View;
    
    import androidx.appcompat.app.AppCompatActivity;
    
    
    public class MainActivity extends AppCompatActivity implements View.OnClickListener
    {
    
        @Override
        protected void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
    
            findViewById(R.id.btn_next).setOnClickListener(this);
        }
    
        @Override
        public void onClick(View v)
        {
            if (v.getId() == R.id.btn_next)
            {
                startActivity(new Intent(this, NextActivity.class));
    
            }
        }
    
    
    }
