Java 片段切换降低了Android应用程序的速度

我正在开发一款Android应用程序，它有三种支付模式的

片段，即CardFragment，NetBankingFragment，WalletFragment

在NetBankingFragment中，我有多个基本上代表不同银行的
图像视图

下面是我的XML代码，用于表示网络银行UI的片段\u nb\u视图

这似乎表明，mainthread本身做了太多的处理，但我不知道其他方法如何做

请提供帮助。
在Android Studio中使用traceview工具，并对方法调用进行分析。好的。我已经做了，但是我如何解释数据呢？我是新来的Android发现问题出在图像上。使用更小的图像&像毕加索这样的图书馆解决了这个问题
