i have a preferences screen , and i want to add a button, imageview etc all in a relative layout within the preferences screen.How do i do it?
The preferences screen has 3 checkboxpreferences.
thank you in advance.
The best idea is to extend the Preference class, and use setWidgetLayoutResource on the constructor for your RelativeLayout. The widgetLayout is the area to the left of the title and summary. If you want to change the whole preference, you need to use setLayoutResource. In this case there are some restrictions:
This layout should contain a ViewGroup
with ID widget_frame to be the parent
of the specific widget for this
Preference. It should similarly
contain title and summary.

I'm looking at Youtube examples and I see the instructor has Widgets I don't have, Like different size Text Fields and an analogue clock.
Is there somewhere I can get more Widgets?
I obtained a text size same as to the "tutorial" using:
android:textAppearance="#style/TextAppearance.AppCompat.Large"
Looks like AndroidStudio has undergone some change. Best option is to enter the "Text" mode and type the style yourself. For ex. if you need an equivalent of LargeText view, then add a TextView and move onto the Text mode and add this line:
android:textAppearance="#style/?android:attr/textAppearanceLarge"
Or you could also edit the properties of TextView too.
You should add this line android:textAppearance="#android:style/TextAppearance.Large"
inside the TextView after clicking on the Text tab near Design tab located in the middle left to the right of design tab.
but you have to consider that first of all you need to drag and drop TextView from Widgets into the user interface or Design section.
Click into the Text tab located middle left to the right of the Design tab, find the TextView element and within it simply enter this line of code:
style="/?android:attr/textAppearanceLarge"
Remember this line of code has to be within the element in order for it to work.
Go to properties and then select text appearance and select app.
combat.large
Use this:
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge"
Add it inside your Textview tag.
I have a QTreeView widget placed inside a QDockWidget:
I want to set the properties of the QTreeView, that it automatically fills the whole available client drawing area (similar as WinForms DockFill property).
How can this be achieved with the QT-Designer?
Note: I've been playing around with the QTreeViews sizePolicy properties. If these are set to Expanding (as is the default) the accepted answer works out out of the box.
In Qt Designer, right-click the dock-widget, and then select Lay out -> Lay Out Vertically from the menu. Or you can just click on the dock-widget to select it, and then use the equivalent layout toolbar buttons.
If you want to maximise the space taken up by the tree-view, select the first child widget of the dock widget (it will probably be shown as dockWidgetContents in the Object Inspector pane). Then scroll down to the bottom of the Property Editor, and reset all the margins to zero.
In Eclipse, I can right - click on my layout (say LinearLayout) and click on Change Layout
In Android Studio, I dont see anything like that. I do see Morphing but that will now show up at all times. For example, if you create simple HalloWorld with RelativeLayout, if you right click on that Layout while in Graphical mode, Morphing will not show.
If you right click on a widget in that layout, Morphing shows but to change widget type, not layout type.
If you want to change the Layout, you can do Two things:
OPTION 1
1. Simply click into your Xml file and select the "Text" option at the bottom on your screen
2.Change to layout
OPTION 2
1.Just drag another layout in Design and put your items in it, delete your old layout PS. you can have layouts in other layouts
Hope I helped!
In Android Studio 3.6.3 the easiest way to change the Layout is to right-click on the layout in your Component Tree and click Convert view….
The other option is to delete this layout and create new activity layout with type you want to be.
You also can use AbsoluteLayout, just change RelativeLayout to AbsoluteLayout in activity_main.xml. With AbsoluteLayout you're more "free"
I need to create a button that looks like this:
button
I was hoping to create it without using images. To create the pink part, I wanted to use a drawable.
How can I include a shape drawable within a button?
You can create a Layout, set background color for that layout as you wish. In that layout add two textviews. Set background for one layout pink. add another under the first textview. Then you can set onClickListener on layout. It'll work same as that of button and it'll be easy to change colors and text programatically.
Try using an ImageButton and setting android:src to point to your ShapeDrawable resource.
Can we change Command's background color of the menu in LWUIT ?
and how can I set an icon to the "Menu" generated Command ?
thanks
I will try to explain better than the other post. You can change the style of the Menu using and UIID.
There are two ways to do that.
Easy way. Use the LWUIT Resource editor and create in the Unselected tab, and UIID called Menu. In this UIID you should configure the background color as you wish. You can change more things (like text color, size of the font, etc)
Hard way, by code. Create a Style object and set it to the Menu.
