import androidx.appcompat.app.AppCompatActivity;

import java.util.Random;

public class MainActivity extends AppCompatActivity {

    private Button button;

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

        button = findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 生成随机颜色
                Random random = new Random();
                int color = Color.rgb(random.nextInt(256), random.nextInt(256), random.nextInt(256));

                // 设置背景色
                button.setBackgroundColor(color);
            }
        });
    }
}
