Camera2 API：保持自动旋转，但不旋转相机预览和按钮

Question

I am looking for a solution to keep the SCREEN ORIENTATION in auto mode, but that the preview of the camera does not rotate. Any suggestions?

Answer 1

You need to mention android:screenOrientation="portrait" or android:screenOrientation="landscape" under the activity tag in your manifest file (ie AndroidManifest.xml) if you want to make your activity's orientation fixed (this is the activity in which the preview of camera is being shown by you).

Like for example -

<activity
            android:name="com.something.camera.CaptureActivity"
            android:screenOrientation="portrait"
            android:windowSoftInputMode="stateHidden" />

Answer 2

使用旋转动画SEAMLESS ，并实现横向和纵向UI，以将预览窗口小心地放置在同一位置。
