你好，看一下你的调用方法写在哪里

[258188170]

调用方法比较多但是每次都new了的 tDialog = new TDialog.Builder(getSupportFragmentManager()) .setLayoutRes(R.layout.dialog_version_upgrde) .setWidth(Constants.DIALOG_WIDTH) .setCancelableOutside(false) .setOnBindViewListener((viewHolder) -> { viewHolder.setText(R.id.tv_content, msg); viewHolder.setText(R.id.tv_cancel, getString(R.string.txt_retry)); TextView confirm = viewHolder.getView(R.id.tv_confirm); if (list != null && list.size() > 0) confirm.setText(getString(R.string.txt_use_em)); else confirm.setText(getString(R.string.model_setting));

            })
            .addOnClickListener(R.id.tv_cancel, R.id.tv_confirm)
            .setOnViewClickListener((viewHolder, view, tDialog) -> {
                switch (view.getId()) {
                    case R.id.tv_confirm:
                        tDialog.dismissAllowingStateLoss();

                        if (list != null && list.size() > 0) {
                            //使用应急码
                            mPresenter.clickedEmergency(list);
                        } else {
                            // 跳转到设置界面
                            startActivity(new Intent(Settings.ACTION_WIFI_SETTINGS));
                        }
                        break;
                    case R.id.tv_cancel:
                        mPresenter.checkNetworkInfo();
                        tDialog.dismissAllowingStateLoss();
                        break;
                }
            })
            .setOnKeyListener((anInterface, i, keyEvent) -> {
                if (i == KeyEvent.KEYCODE_BACK) {
                    finish();
                    return true;
                }
                return false;
            })
            .create()
            .show();

这个异常我没复现,但是友盟统计上一直上报

[258188170]

[258188170]

不同界面都报这个空指针异常

[Timmy-zzh]

你好，我需要知道你在哪里 new TDialog.Builder()，因为我要分析虚拟机栈信息，根据你提供的资料在调用performLaunchActivity()时触发异常，我想知道你调用new TDialog.Builder()的入口函数在哪里？可以的话加我微信（Timmy_zzh）
