How to handle stickers with resize and rotate functionality? [closed]

由 谁说胖子不能爱 提交于 2019-12-02 14:32:22
I am currently developing an application which will allow user to add stickers (hat, hairs, spectacles etc) on image. User can resize that sticker or can rotate that and move also. See image. I have stickers, but how can I put them on original image and move/rotate/enlarge them to adjust on original image? You can check the below link for stickerView https://github.com/nimengbo/StickerView https://github.com/kencheung4/android-StickerView https://github.com/uptechteam/MotionViews-Android https://github.com/wuapnjie/StickerView https://github.com/sangmingming/StickerView https://github.com

Pinch Zoom and Pan

由 旧巷老猫 提交于 2019-12-02 10:24:42
I have an activity with LinearLayout as its main Layout. In that layout, there is a button that adds a View (R.layout.motor_block) to the main layout (R.id.layout): LayoutInflater inflater = (LayoutInflater)this.getSystemService( Context.LAYOUT_INFLATER_SERVICE ); View iv = inflater.inflate( R.layout.motor_block, null ); RelativeLayout rl = (RelativeLayout) findViewById(R.id.layout); rl.addView(iv); This works fine, but when I add more Views, the screen gets filled up with them so I need a way to "extend" the size by adding pan so I can go through all the views. I also want to add zoom. I

Android pinch-to-zoom layout inside a viewpager with padding left and right

由 柔情痞子 提交于 2019-12-01 09:24:17
问题 I have a viewpager with left and right padding for showing the previews of left and right pages of viewpager. viewPager.setPadding(30,0,30,0); The content of the viewpager is a zoomlayout borrowed from here. So the issue is, whenever I zoom the layout from the viewpager, the only visible zoom is at top and bottom. Zooming is not visible to the left and right due to padding. Screenshot before zooming Screenshot after zooming The zoomed view is limited inside the viewpager padding. I need the

How to pinch zoom an edittext in android?

由 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

There is not a lot of information on this, and the little that I have been able to find is very vague and unhelpful.

Zoomable TextView in ScrollView

由 柔情痞子 提交于 2019-11-30 19:28:59
问题 I would like to make a TextView that can change the size of it's text based on pinch zooming. The TextView is inside a ScrollView . I've got the TextView to zoom when pinching BUT only when you move your fingers almost perfectly horizontally. If there is a vertical component to the pinch-zoom it defaults to scrolling instead of zooming Is there a way to disable the scrolling of the ScrollView when there is more than 1 pointer on it then re-enable scrolling when the pointer count returns to 1

after canvas zoom with pivot point, x- and y- coordinates are wrong

由 家住魔仙堡 提交于 2019-11-30 17:46:39
问题 I am trying to implement zooming on a canvas which should focus on a pivot point. Zooming works fine, but afterwards the user should be able to select elements on the canvas. The problem is, that my translation values seem to be incorrect, because they have a different offset, than the ones where I don't zoom to the pivot point (zoom without pivot point and dragging works fine). I used some code from this example. The relevant code is: class DragView extends View { private static float MIN
