我尝试在退出警报时实施原生广告。而我得到了这个错误

Process: com.developer.app, PID: 9244

这是我的主要活动代码

    }

                    NativeTemplateStyle styles = new
                            NativeTemplateStyle.Builder().build();

                    TemplateView template = findViewById(R.id.my_template_native);
                    template.setStyles(styles);
                    template.setNativeAd(unifiedNativeAd);

                }
            })
            .build();

    adLoader.loadAd(new AdRequest.Builder().build());

我知道错误显示为“ java.lang.NullPointerException：尝试调用虚拟方法'void com.google.android.ads.nativetemplates.TemplateView.setStyles（com.google.android.ads.nativetemplates.NativeTemplateStyle）”空对象引用”

这是我的activity_main.xml
