Gesture Listener across entire device

问题 I was looking at an application (SwipePad), and noticed that after the application launches, it detects gestures across the entire platform, even after the main part of the application as been sent to the back (onPause... i.e. it isn't the current activity). It looks like it's using some kind of system service to keep itself alive, but how is it still getting the gesture from the bezel at the system level like that? It also was interesting that the application itself isn't using root. Any

How to pinch zoom an edittext in android?

烂漫一生 提交于 2019-12-01 09:02:52
问题 Please suggest a way to zoom all the contents of the edittext when a pinch gesture is detected. Want to zoom like typical text editor apps like KingSoft and quickoffice. 回答1: It's going to be nasty, but you can subclass EditText . In your subclass, override onTouch and pass its values to a ScaleGestureDetector . Store the detected scale as a member variable. Override onDraw , and call canvas.scale() with your scale value prior to calling through to super.onDraw . This is likely to wreak havoc

Path intersection in android

此生再无相见时 提交于 2019-11-30 14:43:48
I have 2 path objects in my android code.I have tried all the way to check whether these paths are intersected or not, but not able to do it. How can I check whether the paths are intersected or not. Appreciate any good response, Thanks ! have a look at Region.op I haven't tried it but I would suggest to use: Region.setPath(Path path, Region clip); to get a region from both of your paths and afterwards you can use: if (region1.op(region2,Region.Op.INTERSECT)) { // intersection } to check for intersection...
