[英]How do i prevent my android layout from turning horizontal/landscape when the device is being held horizontally
[英]Android - Landscape Layout not being used when Orientation is changed
我目前正在為我的機器人團隊開發一個應用程序,以用於即將到來的比賽。 我一直在使用導航抽屜模板,並且一直在努力工作,但遇到了一個主要問題。 我發現,每當我定向該應用程序時,它將從第一個片段轉到原始布局。 我通過android:configChanges="keyboardHidden|orientation|screenSize"
將其修復為AndroidManifest.xml
,並修復了原始問題,但又創建了另一個問題。 雖然更改方向不會更改布局或破壞片段,但該應用程序將不會加載我的風景布局,並且與layout-land
文件夾中的文本框相比,我所有的TextBoxes都將不合適。 我知道我必須使用onConfigurationChanged(Configuration newConfig)
但是我不知道應該將它放在哪里或應該放在里面(在Java編程中不是很高級)。 應該在我的一個或所有片段文件夾中嗎? 應該在主要活動課中嗎? 如果可以的話,請幫我。 這是我的MainActivity.class
,如果您需要我的片段類,請告訴我。
謝謝,薩默爾
