I want to know the process of creating Tiles on home screen , could you help me
I do not know what you mean by “Tiles on home screen”, sorry.
I have 1 background Image and 1 icon image , I want to insert icon image at a specific part (lower right) of the Background image
Is it possible…
- set rootlayout to framelayout
- Set background to
- add an imageview . set src to
- set imageview’s
is it possible to call all these from Java class file
setting your layout to framelayout is a choice that you have to take in xml only.
Rest all of them can be done by java.
Framelayout root =findviewbyid(R.id.framelayout_xml_id); root.setbackgroundDrawable(R.drawable.bg); //if image view is already created in xml and is hidden Imageview iv =f...i...d(R.id.imageview); iv.setVisibility(View.VISIBLE); iv.setImageResourceFile(R.drawable.icon_pic);
Some of the method names might be incorrect/not in proper camelCase format as i am on the phone. Also, if you need to even create the imageview in java, then that is also possible
I want to know What is Layout Inflater, where and how it can be used .
LayoutInflaterknows how to “inflate” layout resources. In Android, “inflate”
Walk a tree of XML elements in an XML resource
Create Java objects for each element in that tree
Stitch those objects together into their own tree structure, mirroring the
tree defined in the XML
Return the Java object representing the root of the tree
We use it for creating rows/cells/whatever in a
RecyclerView, for loading the contents of fragments in
onCreateView(), etc. Under the covers, things like
LayoutInflater, even though we do not use it directly there.
I want to know ,
- How to arrange Launcher icons on Home screen as shown in picture(like Matrix form) and
- How to provide Drag and Drop feature for those icons
- I want to give Focus for one icon when nothing is selected
I would use a
RecyclerView with a
I would look for a library that might offer that for
I have not played with the new-ish
recyclerview-selection library — perhaps you can put something together using that.
But I want image be placed some part out of frame layout
I mean, half inside the layout and half outside the layout , is it possible
I am sorry, but I do not know what you mean. Note that with a
RecyclerView, you are still in control over what each grid cell contains. Whether that is just an
ImageView, or whether that is an
ImageView in a
FrameLayout, is up to you.
But as you said in the beginning of my question , image view position can be adjusted using gravity - end… "Still I want image position some part out side of the layout "
At this point, I have no idea how to help you further. I apologize for my inability to understand what you want.
I do not know how this relates to the grid of icons that you asked about previously. If this is a single item in that grid, then that forms a single item in the
For single item , if I take Linear Layout will it (Image view)be visible which is at outside of the layout
And How to give Drag and Drop property to this single item
You could use the system drag-and-drop techniques that I wrote about in The Busy Coder’s Guide to Android Development.
You could look into handling
MotionEvents yourself, if you wanted. I have not dealt with low-level drag-and-drop like that in several years, so I do not have any current advice. However, there are lots of libraries and samples in the Android Arsenal on dragging views, so some stuff in there may prove useful.
