![]() 90° clockwise (90° CW), then choose Edit > Transform > Rotate 90° Clockwise.180°, then choose Edit > Transform > Rotate 180°.There are also predefined rotation values (180°, 90° CW, 90° CCW) you can use. If you’ve already applied the rotation but you are not satisfied with it, you can press the Ctrl + Z to restore the layer’s original orientation. Press Enter or click on the check mark at the top bar menu when you are satisfied with the result. Positive values will result in a clockwise rotation, while negative values will result in a counter-clockwise rotation. Enter the exact value in the Rotate field in the menu bar at the top if you want to rotate the layer by the specific degree amount. You can also press Shift to rotate in increments of 15° in any direction. Apply rotation by dragging the pointer to the desired direction. You will be able to rotate when your pointer turns into a curved, two-sided arrow. You can achieve the same by pressing the Ctrl + T shortcut. From the top menu bar, choose Edit > Transform > Rotate or Edit > Free Transform after which a bounding box appears. Select the layer you want to rotate by clicking on it in the Layers panel. I will show you a few different methods you can use for rotating the layer so you can decide which one suits your needs best. This simple technique will help you in many of those situations where rotation is needed. Whether you do logo design or photo-editing you’ll always have to rotate some elements a bit. If it is, it means that the proximity sensor is not available.In this tutorial, you’ll learn how to rotate a layer in Photoshop. SensorManager.getDefaultSensor(Sensor.TYPE_PROXIMITY) īefore proceeding, always make sure that the Sensor object is not null. You can now create a Sensor object for the proximity sensor by calling the getDefaultSensor() method and passing the TYPE_PROXIMITY constant to it. (SensorManager) getSystemService(SENSOR_SERVICE) To create it, use the getSystemService() method of your Activity class and pass the SENSOR_SERVICE constant to it. To get access to any hardware sensor, you need a SensorManager object. Let us now create an activity whose background color changes to red every time you hover your hand over your device's proximity sensor. Some proximity sensors can also tell how far away the object is, though their maximum range is usually only about 5 cm. Ever wondered how your phone determines whether or not it is close to your ear? Well, it uses the proximity sensor, which is a hardware sensor that can tell if an object is close to it. In order to avoid accidental touch events, your phone's touchscreen goes black during calls, when it's very close to your ear. Note, however, that because the tag doesn't help if a user installs your app manually using its APK file, you must still programmatically check if a sensor is available before using it. The manifest file should look something like this now: Therefore, add the following lines to your manifest file: The app we'll be creating in this tutorial will not work on devices that lack a proximity sensor and a gyroscope. You can let Google Play and other app marketplaces know about your app's hardware requirements by adding one or more tags to your Android Studio project's manifest file. If your app is simply unusable on devices that do not have all the hardware sensors it needs, it should not be installable on such devices. ![]() An Android device with a proximity sensor and a gyroscope. ![]() To follow along, you'll need the following: ![]()
