Question

我在应用程序中有多个对话框片段。当屏幕变得更暗时，一次又一次显示对话框，就像出现对话框时一样。如果我从任务管理器中删除应用程序并再次打开，则解决了Probelem问题。有趣的是，在Android 7.0+问题上没有出现问题。我检查了日志，一切正常，代码正在执行。以下是其中一个对话框片段：

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

    @BindView(R.id.text_bank_title)
    TextView tvTitle;

    @BindView(R.id.text_value_manager)
    TextView tvManager;

    @BindView(R.id.text_value_phone)
    TextView tvPhone;

        dialog.setArguments(bundle);

        make(activity, dialog);

    }

        Bundle bundle = new Bundle();
        bundle.putParcelable(ARG_BANK, bank);
        dialog.setArguments(bundle);

        make(activity, dialog);

    }

    protected static void make(Activity activity, DialogFragment dialogFragment){
        if (activity != null){
            android.support.v4.app.FragmentTransaction transaction = ((FragmentActivity) activity).getSupportFragmentManager().beginTransaction();
            dialogFragment.show(transaction, "");
        }

            getDialog().dismiss();
            return;
        }
        presenter = new BankBranchPresenter(this, bank);

    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        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);
    }
}

没有错误时的外观：

此错误：

这可能是什么原因？

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

对话框片段在执行代码时有时不显示
