执行代码时有时不显示对话框片段

Question

我在应用程序中有多个对话框片段。当屏幕变暗时，一次又一次没有显示对话框，就像出现对话框时一样。如果我从任务管理器中终止应用程序并再次打开，问题就解决了。有趣的是，在 Android 7.0+ 上不会出现问题。我检查了日志，一切正常，正在执行代码。这是其中一个对话框片段：

public class DialogBankBranch extends DialogFragment implements View.OnClickListener, BankBranchView{

        View view = inflater.inflate(R.layout.dialog_map, container);
        ButterKnife.bind(this, view);

        tvTitle.setText(bank.getBranch());
        tvManager.setText(bank.getManager());
        tvPhone.setText(bank.getPhone());
        tvEmail.setText(bank.getEmail());
        tvEmail.setOnClickListener(this);
        tvPhone.setOnClickListener(this);

        Spanned info = Html.fromHtml(LanguageUtil.isUzbek() ? bank.getInfoUzb() : bank.getInfo());
        tvInfo.setText(info);

        return view;
    }

    @Override
    public void onClick(View v) {
        presenter.onClick(v.getId());
    }

    @Override
    public void start(Intent intent) {
        startActivity(intent);
    }

    public void showError(String msg) {
        MyToast.show(msg);
    }

    public void showError(int msgId) {
        MyToast.show(msgId);
    }
}

没有错误时的样子：

这个错误：

这可能是什么原因？

Answer 1

因为您正在使用 fragmentManager 创建 dialogFragment，而您应该使用 fragmentChildManager 进行嵌套片段
