Android 具有可绘制文件夹中的图像的Listview正在播放或延迟

大家好。这是我的密码。我的listview在上下滚动后变得越来越慢，然后应用程序被关闭。只是想澄清一下。。。我有2个文本视图、1个图像视图和1个搜索字段。我的listview有100多个带有图片的项目

这是我的密码。为了方便起见，我只放了两个项目。我应该放什么？放在哪里？我是个新手。救救我

这是一个很好的实践使用视图持有人和检查出教程这将有助于你。嗯，我不知道如何做到这一点。我无法在代码中使用视图持有者。。。有人能帮我吗？我试过了。但我是个新手。。。所以，如果有人帮我纠正这一点，我会很感激的@用户1550421您不能使用它是什么意思？你当然可以。检查链接，或者简单地搜索ListView视图持有者模式以获取更多信息。
