如何将随机颜色添加到主活动中带有按钮的主活动片段布局

// 主活动布局文件 activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <FrameLayout
        android:id="@+id/fragment_container"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />

</LinearLayout>

// 片段布局文件 fragment_layout.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <Button
        android:id="@+id/color_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Add Random Color" />

</LinearLayout>

// 片段类 RandomColorFragment.java
public class RandomColorFragment extends Fragment {

    private Button colorButton;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_layout, container, false);
        colorButton = view.findViewById(R.id.color_button);
        colorButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int randomColor = generateRandomColor();
                view.setBackgroundColor(randomColor);
            }
        });
        return view;
    }

    private int generateRandomColor() {
        Random random = new Random();
        int red = random.nextInt(256);
        int green = random.nextInt(256);
        int blue = random.nextInt(256);
        return Color.rgb(red, green, blue);
    }
}

// 主活动类 MainActivity.java
public class MainActivity extends AppCompatActivity {

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

        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.add(R.id.fragment_container, new RandomColorFragment());
        fragmentTransaction.commit();
    }
}
