How to keep the textComponent both float label and hint at the center of the screen horizontally. I've tried the alignment of the uiid like floatingHint, TextComponent, TextField etc to center in theme but nothing works.
TextModeLayout tl = new TextModeLayout(3, 1);
setLayout(tl);
TextComponent fname = new TextComponent().labelAndHint("Fname");
fname.focusAnimation(true);
fname.onTopMode(true);
fname.getAllStyles().setAlignment(Label.CENTER);
add(tl.createConstraint().widthPercentage(100).horizontalAlign(Label.CENTER), fname);
You would need to encapsulate the text mode layout in a layout that will center align. Notice width at 100% is the opposite of center align for the table. Also using the Style object would be problematic since we manipulate the UIID and erase your changes.
Specifically this should do that:
setLayout(new BorderLayout(BorderLayout.CENTER_BEHAVIOR_CENTER);
TextModeLayout tl = new TextModeLayout(3, 1);
Container myContainer = new Container(tl);
TextComponent fname = new TextComponent().labelAndHint("Fname");
fname.focusAnimation(true);
fname.onTopMode(true);
myContainer.add(tl.createConstraint().widthPercentage(100), fname);
add(CENTER, myContainer);

i want to add a background color to my container i tried everything but it's not working i didn't know why
Container c2 = new Container(BoxLayout.y());
for (int i = 0; i < lis.size(); i++) {
Container c1 = new Container(BoxLayout.y());
ImageViewer iv = new ImageViewer();
iv.setImage(Image.createImage("/" + lis.get(i).getImage()).scaledHeight(100).scaledWidth(100));
c1.add(iv);
c1.add(new Label(lis.get(i).getNom()));
c1.getUnselectedStyle().setBorder(Border.createLineBorder(5));
c1.getStyle().setBgColor(0xC40C0C);
c2.add(c1);
}
f.add(c2);
Border overrides background color which can impact the background. Also you will need to set the background transparency which in container is 0 e.g.:
c1.getUnselectedStyle().setBgTransparency(255);
I would suggest doing this in CSS or in the designer tool by defining a UIID to match your desired appearance then applying that using c1.setUIID("MyStyledBackground");.
You can have a border on top of the color by nesting containers.
I tried to use a com.codename1.components.FloatingActionButton in combination with a com.codename1.ui.TextArea.
Now I have two questions:
Apparently the valign is not honored - is it a bug?
The actionListener of the FloatingActionButton is not called. Is anything wrong with my usage or is it a bug?
Here is the code to demonstrate it:
public class FormFabOnText extends Form {
public FormFabOnText() {
setTitle("FormFabOnText");
setLayout(new BorderLayout());
Container contentPane = getContentPane();
contentPane.add(BorderLayout.NORTH, new SpanLabel(
"This form contains a TextArea and a FloatingActionButton combined by bindFabToContainer. "
+ "It demonstrates that the FloatingActionButton is not working in this constellation."));
TextArea textArea = new TextArea();
float iconDefaultSize = FloatingActionButton.getIconDefaultSize();
try {
FloatingActionButton.setIconDefaultSize(2.0f);
FloatingActionButton floatingActionButton = FloatingActionButton.createFAB(FontImage.MATERIAL_CLEAR);
Container containerFab = floatingActionButton.bindFabToContainer(textArea, Component.RIGHT, Component.CENTER);
floatingActionButton.addActionListener((e) -> textArea.setText(""));
contentPane.add(BorderLayout.CENTER, containerFab);
} finally {
FloatingActionButton.setIconDefaultSize(iconDefaultSize);
}
}
}
The text area has 0 height so when you valign to the center the button correctly places itself on top. Then you add it to a border layout which stretches it across but the preferred size of the text area determines the valign so it stays.
I'm not sure if there is a good workaround for that other than a bit of margin like we did in the msuikit demo.
The issue with tapping during editing is probably related to the native editing peer. Tapping inside the text area gets sent to the native layer for editing otherwise elements below might cause an issue. Text input is a peer but also a very special case.
In my app, I can't figure out how to properly style the toolbar with my logo image.
What I want to make it look like is pretty much like the Toolbar from the "Sport1" App.
Example
So I need the back Command on the left side of the toolbar, my logo in the middle from a MultiImage out of the resource and on the right another command.
Also, I'd like to let the Toolbar get smaller with scrolling.
What I have tried so far:
res_theme = r;
Form f = new Form(" ", new BoxLayout(BoxLayout.Y_AXIS));
logo = res_theme.getImage("Logo_Gema_vertikal.png");
f.getToolbar().getTitleComponent().setUIID("toolbar_image");
Style stitle = f.getToolbar().getStyle();
stitle.setBgTransparency(0);
stitle.setBgImage(logo);
stitle.setBackgroundType(Style.BACKGROUND_IMAGE_ALIGNED_CENTER);
stitle.setPaddingUnit(Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS);
stitle.setPaddingTop(5);
So, this looks good the way it is. I dont actually need a Title, thats why I do
Form f = (" ", ...);
If I don't add a title to the form, the toolbar gets very small and squeezes the background Image from the toolbar. The centered logo from the toolbar is just for styling reasons there, it does not need to have a command. Is there a way to leave out the Title? I now have set it to completely transparent, but for me this is just a work-around.
Also, I guess rather than setting the logo as background with a centered alignment, I think it would be better to add it to the title section as Image, but I don't know if this is better or how to do it.
Now, I also want to make the Toolbar get smaller when scrolling down. I found kind of a example code in the Codename One Toolbar Documentation, but it does not work out for me, since the background Image gets removed.
This was the code for the scrolling Animation:
ComponentAnimation title = f.getToolbar().getTitleComponent().createStyleAnimation("Title", 200);
f.getAnimationManager().onTitleScrollAnimation(title);
In the example, it worked. With my toolbar it does not, I have no clue why. I also can't see, where the size of the "after scrolling toolbar" is set.
Can I add there an Image as well? Kinda like one toolbar before scrolling with my logo, then while scrolling it transforms into a smaller one with only a textlogo image?
Here is my whole code what I have tried to make it work:
Form f = new Form(" ", new BoxLayout(BoxLayout.Y_AXIS));
logo = res_theme.getImage("Logo_Gema_vertikal.png");
f.getToolbar().getTitleComponent().setUIID("toolbar_image");
Style stitle = f.getToolbar().getStyle();
stitle.setBgTransparency(0);
stitle.setBgImage(logo);
stitle.setBackgroundType(Style.BACKGROUND_IMAGE_ALIGNED_CENTER);
stitle.setPaddingUnit(Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS);
stitle.setPaddingTop(5);
f.add(new SpanLabel("asdasdasdasd");
ComponentAnimation title = f.getToolbar().getTitleComponent().createStyleAnimation("Title", 200);
f.getAnimationManager().onTitleScrollAnimation(title);
f.show();
From the example above if looks like you just want to use the image as the title instead of styling the toolbar with a background image.
Just use ((Label)toolbar.getTitleComponent()).setIcon(myImage);.
I have a written a custom toolbar. And I am having tough time to make it work (design wise). I have a couple of questions regarding it.
1)The main issue I am facing is to place the menu icons in their exact positions. When I tested it in different devices the gaps betn them is different.I have used table layout and grid layout for the menu icons as well & the logo in layered layout but the result is not good.
Code:
void addTitle(Form form, Resources theme) {
Toolbar toolbar = new Toolbar();
form.setToolbar(toolbar);
Container containerTitle = new Container(new BorderLayout());
Image titleImage = theme.getImage("toolbar_bg.jpg");
containerTitle.getAllStyles().setBgImage(titleImage);
containerTitle.getAllStyles().setBackgroundType(Style.BACKGROUND_IMAGE_TILE_HORIZONTAL);
containerTitle.setPreferredH(titleImage.getHeight());
ScaleImageButton ruslanLogo = new ScaleImageButton();
toolbar.setTitleComponent(LayeredLayout.encloseIn(containerTitle,
FlowLayout.encloseCenter(ruslanLogo)));
Image ruslanLogoImage = theme.getImage("ruslanLogo.png").scaledWidth(toolbar.getPreferredH() - 180);
ruslanLogo.setIcon(ruslanLogoImage);
Image emergencyImage = theme.getImage("emergency.png");
Image receipeImage = theme.getImage("receipe.png");
Image fmImage = theme.getImage("fm.png");
Image gameImage = theme.getImage("game.png");
TableLayout tableLayout = new TableLayout(1, 5);
//GridLayout gridLayout = new GridLayout(5);
Container tableContainer = new Container(tableLayout);
Button emergencyButton = getButton(emergencyImage);
emergencyButton.getAllStyles().setAlignment(Label.CENTER);
Button fmButton = getButton(fmImage);
fmButton.getAllStyles().setAlignment(Label.CENTER);
Button gameButton = getButton(gameImage);
gameButton.getAllStyles().setAlignment(Label.CENTER);
Button receipeButton = getButton(receipeImage);
receipeButton.getAllStyles().setAlignment(Label.CENTER);
Button transparentButton = getButton(receipeImage);
transparentButton.getAllStyles().setAlignment(Label.CENTER);
transparentButton.setVisible(false);
tableContainer.addComponent(tableLayout.createConstraint().widthPercentage(20), BoxLayout.encloseY(emergencyButton));
tableContainer.addComponent(tableLayout.createConstraint().widthPercentage(20), BoxLayout.encloseY(fmButton));
tableContainer.addComponent(tableLayout.createConstraint().widthPercentage(20), BoxLayout.encloseY(transparentButton));
tableContainer.addComponent(tableLayout.createConstraint().widthPercentage(20), BoxLayout.encloseY(gameButton));
tableContainer.addComponent(tableLayout.createConstraint().widthPercentage(20), BoxLayout.encloseY(receipeButton));
containerTitle.addComponent(BorderLayout.SOUTH, tableContainer);
toolbar.revalidate();
}
2)I have checked the width and preferred width, they differs. Does it affects the design?
int width = emergencyButton.getWidth(); //60
int preferredwidth = emergencyButton.getPreferredW(); //74
3)In above code, I used the bg image height to set the height of the toolbar. "containerTitle.setPreferredH(titleImage.getHeight());" Is it the good way to set height? Because the height changes slightly in android mobiles I have tested, however it looks horribly big in tabs, and I tested it in different simulator, the height differs greatly. How have you set the toolbar height in normal toolbar?
Image titleImage = theme.getImage("toolbar_bg.jpg");
containerTitle.getAllStyles().setBgImage(titleImage);
containerTitle.getAllStyles().setBackgroundType(Style.BACKGROUND_IMAGE_TILE_HORIZONTAL);
containerTitle.setPreferredH(titleImage.getHeight());
ScaleImageButton ruslanLogo = new ScaleImageButton();
toolbar.setTitleComponent(LayeredLayout.encloseIn(containerTitle,
FlowLayout.encloseCenter(ruslanLogo)));
4)How can I set the width of icon?
Image emergencyImage = theme.getImage("emergency.png");
Button emergencyButton = getButton(emergencyImage);
if I just do this, some devices the icon is too big.If I scale it eg: emergencyImage.scaledWidth(screenwidth/8) , the image quality is bad.If I set preferredW like emergencyButton.setPreferredW(100), the img width varies vastly in different devices. PS the images in the theme are saved as multiImage
Setting the preferred width/height is problematic as it implies the inverse dimension and might have quite a few implications. I noticed you used:
Image ruslanLogoImage = theme.getImage("ruslanLogo.png").scaledWidth(toolbar.getPreferredH() - 180);
Which sets the width based on the preferred height instead of the width/5 or something like that. It also sets the value based on preferred height before the toolbar construction is done so things will behave differently.
Preferred width includes padding which might affect your design. I would suggest creating a center aligned 0 padding/margin UIID in the designer and setting it to all of your components to eliminate padding/margin differences and shorten your code.
I am new for Codenameone Is there any option to align a label depends on another label like align bottom, top, right and left option?
How to align many labels at the centre of the parent layout?
Here I have attached the code I tried for:
Container center = new Container(new BorderLayout());
Label des = new Label((String) data.get("title"));
des.setUIID("MultiLine2");
center.addComponent(BorderLayout.NORTH,des);
Label author = new Label((String) data.get("author"));
author.setUIID("MultiLine2");
center.addComponent(BorderLayout.SOUTH,author);
cnt.addComponent(BorderLayout.CENTER, center);
I am getting outpul like the below image
Here I have attached what I need for my project
Can anyone please help me How should I do to get my requirement?
This will place the Labels in the absolute center of the container:
Form hi = new Form("Hi World");
hi.setLayout(new BorderLayout(BorderLayout.CENTER_BEHAVIOR_CENTER_ABSOLUTE));
Container center = new Container(new BoxLayout(BoxLayout.Y_AXIS));
Label line1 = new Label("What are you doing");
Label line2 = new Label("Hello");
center.add(line1);
center.add(line2);
hi.addComponent(BorderLayout.CENTER, center);
hi.show();
To adjust the center to move slightly to the left you can add right padding to the center Container:
center.getAllStyles().setPadding(Component.RIGHT, 100);
These two approaches also serve to center labels inside a CN1 container:
Container container01 = FlowLayout.encloseCenterMiddle();
and
Container container02 = new Container(new GridLayout(2,1));
where the number 2 in GridLayout(2,1) refers to the number of labels you have for one column.
