一种区分OnDismiss和dialogfragment的方法- Android Studio

DialogFragment dialogFragment = new YourDialogFragment();
dialogFragment.setOnDismissListener(new DialogInterface.OnDismissListener() {
    @Override
    public void onDismiss(DialogInterface dialog) {
        // 在对话框关闭时执行操作
    }
});
dialogFragment.show(getSupportFragmentManager(), "dialog");

public class YourDialogFragment extends DialogFragment {
    // ...

    @Override
    public void onDismiss(DialogInterface dialog) {
        super.onDismiss(dialog);
        // 在对话框关闭时执行操作
    }
}
