Android: Recognising Gestures when screen is locked

会有一股神秘感。 提交于 2019-12-02 04:15:19
I am currently in the process of creating an MP3 player. In particular, the main mode of user input is in the form of (touchscreen) gestural input. I would like to add the functionality allowing users to continue interacting with the MP3 player when the screen is locked. That is, how can I get the device (A Galaxy S3 in particular if it's worth mentioning) to recognise gestures in the lock screen and "parse" them to the MP3 player? Note: by "locked" I mean when one can see the lock screen (i.e. not when the screen is turned off). How would I go about doing this? Thanks in advance. The

The meaning of returning false from onDown()

问题 According to android training if you extend GestureDetector.SimpleOnGestureListener , and return false from onDown(...) than the other methods of GestureDetector.SimpleOnGestureListener will never get called: Whether or not you use GestureDetector.OnGestureListener, it's best practice to implement an onDown() method that returns true. This is because all gestures begin with an onDown() message. If you return false from onDown(), as GestureDetector.SimpleOnGestureListener does by default, the

I'm trying to implement a swipe gesture in my app. I've made almost all code but it doesn't work.

Here he my the code of the class SwipeGesture :

Disable cross-slide selection for a listview

I'm designing an app that has a vertically panning one-dimensional list in the centre and the user is able to flip between lists horizontally due to a flipview. When a user drags horizontally within the listview, it selects that row because of cross-slide . This isn't the behaviour I want. Preferably I would want the flipview to start panning left and right. I think it's something to do with rails because when the user pans diagonally, they can pan the flipview. Cross-slide even happens when selectionmode is set to None How do I disable cross-slide, or how do I ensure that when a user pans

I have a screen where I have a header, a TextView inside a ScrollView and footer. I have to use ScrollView as the Text in the TextView can be long also. Now when I am using SimpleOnGestureListener for this screen. It is not working for the ScrollView section. Removing the ScrollView everything working fine. But for the case of long text, some text are getting missed. I want to use onFling and onDoubleTap in SimpleOnGestureListener. Please advise. Regards, Shankar Zaid Daghestani You have to create a custom ScrollView object and override it's onTouchEvents to also check for your gestures. It's
