I want to make an animated splashscreen and the Motion Layout should start automatically when you start the app. What can I do to make the Motion Layout start automatically?
Add the line autoTransition="animateToEnd" to your transition
<Transition
motion:constraintSetStart="#+id/start"
motion:constraintSetEnd="#+id/end"
motion:autoTransition="animateToEnd"
motion:duration="1000">
First, assign an ID to MotionLayout in xml.
then write below codes in your activity:
MotionLayout motionLayout = findViewById(R.id.motion_layout);
motionLayout.transitionToEnd();
if you want to reverse transition use this line of code:
motionLayout.transitionToStart();
The motion:transitionFlags="disableIntraAutoTransition" will avoid the animations reanimating if the actual state is changed programmatically or by the user.
<Transition
motion:constraintSetEnd="#+id/end"
motion:constraintSetStart="#id/start"
motion:autoTransition="animateToEnd"
motion:transitionFlags="disableIntraAutoTransition"
motion:duration="1200">
</Transition>

When I saw the TabBar and the Flyout menu in .NET Maui I started wondering if its possible to create your own global object for your application.
does anyone know how to do this?
(I want to add a status icon at the corner of my screen without having to manually add it to all pages.)
You can create a simple Floating Button and add it to your pages.
You can create an image with a transparent background in your favorite editor and then assign it a location on the Page.
You can refer to the following code:
<AbsoluteLayout>
<!--Other components-->
<ImageButton Source="icon.png"
BackgroundColor="Green"
CornerRadius="80"
AbsoluteLayout.LayoutFlags="PositionProportional"
AbsoluteLayout.LayoutBounds=".95,.95,80,80" />
</AbsoluteLayout>
i am making a java desktop application using javafx. For gui building i am using scene builder 2.0.
Everything is just perfect as expected just 1 thing. I want to customize the buttons. i want to assign a custom graphic to a button.
When i use [button.setgraphic(node)] , this statement set the new graphic to the button but default graphic of button also remains present as well.
I just want to remove the default graphic and then want to assign the new (custom) garaphic to a control like buttons and radio buttons in javafx. 1 thing again i must tell that i am using scene builder for building gui.
How can i achieve this ?
thanks in advance....
Below is the screen-shot of current occuring situation, .....
Here i have made a button using javafx scene builder , and then in the controller of the fxml file (.java file) i am trying to set the image (shown in orange box in snapshot) to that button by using setGraphics property of button ..... i just need that button to be of following shape ...
You'd better customize your button via CSS. Here goes tutorial. What you are trying to do is to modify button picture (which is empty by default). I guess this wasn't your exact purpose.
button.setGraphic(null)
// worked for me.
I'm programming an android app with a list displaying images and some additional information like title, place, etc...
I'm new to the android ecosystem and wondering what are the best practices to implement a list element which normally displays the mentioned information and turns into input fields on a press on the listelement.
Do I have to draw the display elements (e.g. TextField) and the edit element on top of each other and set visible for either display or input? How to handle this generally? Or do I replace the layout responsible for the list element altogether?
I know that for the simple case of a text there is a simple solution for making the EditText field look like an uneditable TextField. I'm, however, looking for a general answer covering broader cases than just a TextField.
Thanks!
you can make the elements of the listview a view flipper having two views.one you textview and other and edittext.
<ViewFlipper
...
<TextView
... />
<EditText
... />
/ViewFlipper>
Then in the onItemClickListener of the list items you can call flipper.showNext();
So, flipper works like, it shows only the first view defined in it and on the subsequent call of showNext() it displays the next view defined in it.
So if you have 2 elements in it, it will behave as the coin with two sides.
So in your situation there are a few ways you can achieve this.
First way is to build a layout which contains TextView and EditText and in first initialization your edit text won't be visible. And in your OnItemClick you have to hide your textview and show editext with value of your current data and option to edit.
The second way which I think is more user friendly is that you can show an AlertDialog after OnItemClick with custom layout where you can change the values and update the listview after user press Yes or do nothing is he selects No.
It depends on you which way you will do that, but I think the second option is the better one.
Per the question here,
What's "tools:context" in Android layout files?
The 'tools' namespace reference (xmlns:tools="http://schemas.android.com/tools") has begun to appear in my layouts recently, and I want to know more. The original post only described the 'tools:context' attribute, but I have also noticed usage of the "tools:listitem" attribute appearing when I have designated a preview layout item for a listview, i.e.
<ListView
android:id="#+id/lvCustomer"
tools:listitem="#layout/customer_list_item" >
</ListView>
Are there more elements?
What brought me to this 'tools' namespace is that I want to be able to have 'preview-only' text (i.e. in a TextView or EditText) when using the layout designer in eclipse.
Currently, I assign the 'text' or 'hint' property for previewing text when arranging my layouts... but then I always have to remember to clear the preview value from within the code.
Ideally, instead of
<string name="preview_customer_name">Billy Bob's Roadhouse Pub</string>
...
<TextView
android:id="#+id/tvCustomerName"
android:text="#string/preview_customer_name"
</TextView>
have a something like:
<TextView
android:id="#+id/tvCustomerName"
tools:previewText="#string/preview_customer_name"
</TextView>
Thanks-
We've just added support for designtime attributes like this in Android Studio 0.2.11. See http://tools.android.com/tips/layout-designtime-attributes for more.
Think of them as design time helpers only.They do not get processed in actual view rendering at run time.
For example you want to set background of some view in your layout design when working on android studio so that you can make clear distinction where that particular view is.So you would normally do that with
android:background="#color/<some-color>"
Now risk is that sometimes we forget to remove that color and it gets shipped in apk.
instead you can do as follows:
tools:background="#color/<some-color>"
These changes will be local to android studio and will never get transferred to apk.
And also check out http://tools.android.com/tech-docs/tools-attributes for more options.
You will find tool attribute when you set object in graphical layout.
Listview (in graphical mode) -> right Click -> Preview List Content -> Choose Layout...
produces:
tools:listitem="#layout/customer_list_item"
See in layout XML below. There are 2 namespace in use "xmlns:android" and "xmlns:tools".
Tools namespace is used when the developer wants to define placeholder content that is only used in preview or in design time. Tools namespace is removed when we compiled the app.
So in the code below, I want to show the placeholder image (image_empty) that will only be visible at design time, and image1 will the actual image that will be shown when the application launch
I have an ImageView inside a RelativeLayout that I added programmatically (The ImageView is added by code, not the RelativeLayout.)
If I had added the ImageView by XML, I would have done this:
<ImageView
android:id="#+id/login_loadingimage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:src="#drawable/imagefilename"
android:visibility="invisible"
/>
But now I want this done programtically. How do I get the centering right? I have tried creating RelativeLaout.Parameters but whe I create them using
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(this, null); //[1]
p.AddRule(...);[2]
An exception is thrown at line 1. In addition I wouldn't know how to apply these LayoutParameters on ViewGroup.LayutParameters anyway.
Also, I cannot just make ViewGroup.LayoutParameters because
1. They do not seem to have the Centering (Horizontal and Vertical) elements I need.
2. Every example seems to indicate there is a Constructor that simply takes Layout_Width and Layout_Height as parameters, but there is not.
Before someone says to add a layout first, please tell me how to center the layout in code as well. Thanks.
Please help.
The way to do it is simple:
Create xaml you want of JUST the component - put the file in the layout folder.
Then use the inflating service to inflate the control inside the code you want (make sure to create the LayoutInflator as follows):
LayoutInflater _inflatorservice = (LayoutInflater)this.GetSystemService(Context.LayoutInflaterService);
Then simply call this:
_inflatorservice.Inflate(Resource.Layout.[control], parent);
