QUESTION
I am working on a bottom sheet dialog and was wondering how to align all 3 textviews to the center as well as align them with the same left margin. Please note that there is also an imageview left to the textview for all 3 rows(Here 3 rows are rename, share and delete). gravity center makes them align to center but their left margin won't be same. I want their left margin to also be same
...ANSWER
Answered 2020-Jun-02 at 10:48There are many ways to accomplish the above.
- You can use vertical LinearLayout and have 3 horizontal LinearLayout's inside, wrapping icon and text view.
- You could also use ConstraintLayout - you'd then have smaller depth of your layout tree.
- You could use RecyclerView where each item would be horizontal LinearLayout, or ConstraintLayout - representing row

QUESTION
I've created a custom renderer for Android and implemented it for a custom Slider control. I've got 2 solutions. In both solutions an Android App is build and started on an Android Phone. The test program shows the slider fine and I can drag the thumb up and down without any problems. The second solution is a bigger one where the slider should be implemented. If I run that solution the slider is displayed but I cannot move the thumb up and down. The OnTouchEvent is never fired. Below is all the code needed for the Slider. I know it's a lot but I hope someone sees the my problem.
My guess is that the ExportRenderer attribute at on the namespace somehow isn't found or triggered. The 'OnElementChanged' override is called but further nothing.
This is the custom renderer for the DraggableView (the thumb of the slider) in the Android project
...ANSWER
Answered 2020-May-22 at 15:26Ok, found it. The control was already working and my mistake was elsewhere. If you watch closely at the XAML you will see that the last StackLayout has no Grid.Row and Grid.Column attributes causing it to be on top of both Sliders. So the touch doesn't go to the sliders but to the ContentView that's inside the StackLayout giving me the impression it's not working.
QUESTION
I'm trying to create a custom renderer that should produce a vertical Slider. The drag of the thumb of the slider works and the thumb starts to slide perfectly if I run it on a tablet emulator. Sizes are detected perfectly. Than I ran it on a my phone and whoops what's that. The thumb suddenly doesn't function as expected anymore. The problem is in the Width and Height of the parent the Thumb is placed upon. On the table emulator I get the expected Width and Height but on my Phone I get unexpected values.
Are sizes not in pixels on Android? Is there some factor I need to take into consideration.
Below is the Custom Renderer. The problem is in this part:
...ANSWER
Answered 2020-May-21 at 13:31parent.width is a width of a container in pixels. It can be less than display width. Also a container may be bigger than display if it overlaps its size (for instance, "android:width="1000dp"). You should add a layout here.
To get a display width see How to get screen dimensions as pixels in Android.
QUESTION
Below is the code I wrote for dragging a rectangle. I would like to restrict its dragging to be within the border of the view given. ie if the user tries to move the rectangle outside the border of the view, it should stay within the border edges. I tried using GeometryReader to get the rect of both the rectangle and the outer view, but I am unable to restrict the drag. Please help.

QUESTION
Here is a very simplified version of my layout. I have a text view that I'm able to drag around...
...ANSWER
Answered 2020-Feb-27 at 19:52Why does this occur?
You drag, you just don't see it because ScrollView clips its content view. Stacks do not, by default. If you add .clipped() for bottom VStack you'll see the same.
Is there any way to enable these views to be dragged outside the ScrollView?
Solution might be using ZStack. Say on drag you hide one view in ScrollView and show same out-of ScrollView at the same global location, so visually it would behave as would drag original.
QUESTION
I am using this code to load a view when I touch a button in Xcode.
...ANSWER
Answered 2020-Jan-07 at 22:28What you are describing is the default behavior of a presented view controller in iOS 13 - presented VCs slide in from the bottom and leave a gap at the top (indicating that the user can dismiss by dragging down).
You can remove the gap (and swipedown behavior) by setting the presented VC's modalPresentationStyle to fullscreen like this:

I have a question. I created a CustomView where I can drag/drop the view inside, but now I also want to add a scale/rotate function to it. Now here is the OnTouchEvent that created to move the view inside:
...ANSWER
Answered 2019-Dec-13 at 07:54There is a xamarin-forms-samples about ScaleAndRotate , however it is not related to TouchEvent .I found a way by using PanGestureRecognizer and PinchGestureRecognizer to implement it .
Create a ScaleAndRotateContainer ContentView which contains PanGestureRecognizer and PinchGestureRecognizer :

QUESTION
I am using this Drag/Drop code: https://github.com/CrossGeeks/DragViewSample/tree/master/DragViewSample/DragViewSample
This works great, but now I want to not just be able to drag/drop an image, but also a click action. The function needs probably be done in the Custom renderer in this part of the code:
...ANSWER
Answered 2019-Dec-11 at 23:23There are lot of fine things that one needs to do here to make it work in a real good way and if you expect that then the question needs to be closed as this is not the site where someone else writes the code for you.
Assuming you are fine with that, I'll give you just very basic idea on how to do it.
The key is in recording the DateTime of touchedDown = true;and comparing it to the DateTime of touchedDown = false; and if it is below some threshold calling it 'click'. If you do just this there will be some artifacts but you need to resolve them.
