The Android App only supports horizontal screen switching or vertical screen switching.

In tablet development, only the horizontal screen switching function is required, and the default activity of the system has the horizontal and vertical screen switching function. How can this problem be achieved?

In fact, it is very simple. You only need to set the attribute in the activity related to the Manifest. xml file:

Android: screenOrientation = "sensorLandscape"

In this way, you can implement the horizontal screen switching function of the app, and the lifecycle method of the activity will not be called during the horizontal screen switching.

Ps: android: screenOrientation = "sensorPortait": the app only supports portrait switching.
