AdMob广告需要花费一些时间才能在Android应用程序中加载

Question

我被困了几个小时。 我已经在应用程序中集成了admob广告，当用户在编辑文本中写一些内容时就添加了admob广告，但是有时加载广告有时会花费一些时间，而有时却会跳过。因此，用户键入文本并移至下一个活动，而我的广告不会及时加载。 你能给我一些解决方案来解决这个问题！

相反，在显示广告的#onAdLoaded()回调，在自然断点显示它#onTextChanged()

@Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if (!Passvalues.adCheck) {
               if (Passvalues.interstitial.isLoaded()) {
                   Passvalues.interstitial.show();
                 }
                Passvalues.interstitial.setAdListener(new AdListener() {
                    @Override
                    public void onAdLoaded() {
                        super.onAdLoaded();
                    }

                    @Override
                    public void onAdClosed() {
                        //finish();
                        Passvalues.interstitial = null;
                    }
                });
