如何打开和关闭片段，在android中点击相同的按钮

<Button
    android:id="@+id/toggleButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Toggle Fragment" />

Button toggleButton = findViewById(R.id.toggleButton);
toggleButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        toggleFragment();
    }
});

private MyFragment myFragment;
private boolean isFragmentVisible = false;

private void toggleFragment() {
    FragmentManager fragmentManager = getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

    if (isFragmentVisible) {
        // 隐藏片段
        fragmentTransaction.hide(myFragment);
        isFragmentVisible = false;
    } else {
        // 显示片段
        if (myFragment == null) {
            myFragment = new MyFragment();
            fragmentTransaction.add(R.id.fragmentContainer, myFragment);
        } else {
            fragmentTransaction.show(myFragment);
        }
        isFragmentVisible = true;
    }

    fragmentTransaction.commit();
}
