使我的第一個應用。剛創建後，我試着讓它全屏。它說：「不幸的是你的應用程序已經停止。」android manifest全屏導致我的應用崩潰

使用logcat的檢查與碰撞相關的Java堆棧跟蹤：https://stackoverflow.com/questions/23353173 /不幸-myapp-has-stopped-how-can-i-solve-this我的猜測是，你得到一個錯誤，AppCompatActivity需要'Theme.AppCompat'或另一個繼承的主題從那。如果是這樣，您需要查看是否存在可以使用的'Theme.AppCompat'的全屏變體，或者移除'appcompat-v7'並使用本機操作欄。 – CommonsWare
全屏幕的另一種方式是將appcompatactivity更改爲Mainactivity類中的Activity。 –
對不起，我無法格式化logcat消息。 – Nirmal
