android - 在插页式广告之前在屏幕上显示进度条

问题描述

我正在开发实现 Admob 插页式广告的 Android 应用程序。我想要的是处理程序锁定屏幕并显示进度条两秒钟，然后显示插页式广告。

我所做的是通过创建动画为插页式广告制作动画，并在InterstitialAd.show方法之后调用它。

 mInterstitialAd!!.adListener = object: AdListener() {
        override fun onAdLoaded() {
            btnstart.setOnClickListener(View.OnClickListener {


                if (mInterstitialAd!!.isLoaded) {
                    mInterstitialAd!!.show()
                    overridePendingTransition(R.anim.in_left, R.anim.nav_default_exit_anim)
                } else {
                    sharpref!!.privacyPolicyAccepted()
                    if (!sharpref!!.isFirstTimeLaunch()) {
                        val intent = Intent(applicationContext, SliderActivity::class.java)
                        startActivity(intent)
                    } else {
                        val intent = Intent(applicationContext, MainActivity::class.java)
                        startActivity(intent)
                    }
                }
            })
        }

代码为overridePendingTransition(R.anim.in_left, R.anim.nav_default_exit_anim)插页式广告设置了动画，但我想要的是在插页式广告打开前两秒钟显示 Pogress 栏。

 btnstart.setOnClickListener(View.OnClickListener {

                    } else {
                        val intent = Intent(applicationContext, MainActivity::class.java)
                        startActivity(intent)
                    }
                }
            }

            override fun onAdFailedToLoad(adError: LoadAdError) {

                    mInterstitialAd!!.show()
                    overridePendingTransition(R.anim.in_left, R.anim.nav_default_exit_anim)
                } else {

                }
            }

解决方案

有关计时器的更多详细信息，请参阅此答案。

快速概览：-

链接中的答案显示了在特定时间后安排某些工作的不同方法。您可以根据自己的要求使用它。

据我从您的问题中了解到的，您可能会有这样的情况：-

if (mInterstitialAd!!.isLoaded) {
     // show Progress Bar visibility here 
        Handler().postDelayed({
            //Hide Progress Bar visibility here 
            mInterstitialAd!!.show()
            overridePendingTransition(R.anim.in_left,R.anim.nav_default_exit_anim)
            }, 2000)
   }

在您之后的这种方法中，您if (mInterstitialAd!!.isLoaded)还可以有一个计时器（提供的链接中的更多详细信息），然后您可以根据需要展示您的广告和动画。
