Android的工作室 - 自定義的ListView崩潰

Question

所以，最近隨後就如何使自定義的ListView這段視頻的說明：https://www.youtube.com/watch?v=D0or0X12FMM

該程序在啓動時發生崩潰，其DOA和展示的任何崩潰之前。

It's not logging any errors to the console.

這是我在視頻+ mainifest所示的零部件代碼：

我有一種感覺它與清單的問題。只是基於其他職位。提前致謝！

Answer 1

就轉到：

Android Studio --> File --> Setting --> Build, execution, deploy --> Instant run。

並禁用即時運行。
