MotionEvent MotionEvent object is used to report movement (mouse, pen, finger, trackball) events.Motion events may hold either absolute or relative movements and other data, depending on the type of device. Android Send text, key pressed and touch events to Android Device via ADB Example. This installment of the Android multi-touch series is about understanding touch events. You can capture these events in your program and take appropriate action as per requirements. The -l option displays textual labels and the -t option displays timestamps. execute the following command to insert the text into a view with a focus (if it supports text input) 6.0. In single-touch events, there is only one pointer (set to 0), so no bitmap mask is needed. Like button presses or screen touch etc. End users get lots of bells and whistles in fancy applications, but for developers, this “open-intended” platform seems even more tangled up than ever. How Android Handles Touches. The reason for this is that some websites use the availability of parts of the touch events API as an indicator that the browser is running on a mobile device. Set up the pc to record data in a file (/tmp/android-touch-events.log) $ adb shell getevent | grep --line-buffered ^/ | tee /tmp/android-touch-events.log do some stuff on the phone; stop the adb command on the pc with ctrl-c; Replay the recorded events. Touch events are typically available on devices with a touch screen, but many browsers make the touch events API unavailable on all desktop devices, even those with touch screens.

Using the touchscreen's device name we can now record events using the command adb shell getevent -t /dev/input/event7 > recorded_touch_events.txt. Using the -t option we also record the timestamps (so that later we can replay the recorded input with the proper delay between events). In multiple touch events (i.e pinch open or pinch close), however, there are multiple fingers involved and a non-zero pointer index may be included when calling getAction().

The inputs events are first passed to the window then to our foreground activity. The first Activity, Touch Sample, will show how to use event handlers for touching the Views. Events are a useful way to collect data about a user's interaction with interactive components of Applications. To detect Touch Event and other events like Left to Right sweep and Right to Left sweep, we use MotionEvent class. Note: Part two on programmatically injecting events on Android has been published and is available here. Showing live events. Record a series of events. adb shell su -- getevent -lt /dev/input/event1 Example: The top foreground activity receives the touch event … Then register the listener to the view object use the view’s setOnTouchListener method.
