Landscape screen switching setting does not refresh the UI

Since Android 3.2 (API 13), screen size has also changed with the switch between devices. Therefore, if the minisdkversion and targetsdkversion attributes set in androidmanifest. XML are greater than or equal to 13 Program Reload the activity at runtime, except for setting" Orientation ", You must also set" screensize ", just like this, Android: configchanges = "Orientation| Keyboardhidden| Screensize ". however, if your target
API level is smaller than 13, your activity automatically handles this screensize change, set Android: configchanges =" orientation | keyboardhidden ". If not, check androidmanifest. the minisdkversion and targetsdkversion values set in XML can run normally if they are less than 13. Otherwise, you must add screensize.
