I'm trying to make an application which has kind a meme generator, I'm wondering,
if I place an image on the screen and I put a textView in there, is there any way to download that image with the text placed on it?
You can use below gitHub library for generating memes
lucas-meme-generator
Best to use in android-studio but also compitible with eclipse/ant or Intellij/maven if you'd like, but some files/directory hierarchies might be slightly different

I have used Picasso in my Android Application which has many images. Its working and looking good. I am trying to make UI more of simple and user friendly. I have placeholder for my imageviews before actual image loads. But its white color. I want to placeholder image depending on main color of image like pinterest.
Pinterest placeholder images before main image loads. Following screenshot:
And after image loads it shows proper image based on main background color shown for placeholder:
Is it possible to achieve in Picasso library provided by Square or whats the way to achieve.
Please help.
Bit late but for other readers that want to accomplish a similar thing, I'll just leave this here. I don't know how Pinterest did/does it, probably developed their own implementation. But Google updated the v7 support library with 'Palette' which is a new API which allows you to extract prominent colours from images when provided with an Image Bitmap.
Edit: Something I just realised that this probably doesn't help for placeholders since you need an image to actually get colours from! So my best guess is that Pinterest does the colour extraction from the server and includes the colour in the (presumably) JSON response that is sent to the client.
I haven't used it much myself but it works quite well from what I've seen/read. You can read up more about it at these two places:
Developer Docs
Tutorial/Explanation (Willow Tree Apps)
You can only do that by saving the prominent color from the image while saving it in your database & then retrieving it for later use.
https://pypi.org/project/extcolors/ is a very easy to use python library that extracts the colors for you given an image.
Or you could you https://github.com/woltapp/blurhash a library that'll give you this.
Both ways, you'll have to first save the BlurHash or The color as a metadata in your database, and then when the user requests the data, you'll send either of those and display them till the data is fully downloaded.
I have made an Android IM Application, and I'm trying to add some stickers and smileys to it, but after lots of searching, seems there is no training about it and where to Start.
I imagine it's a pain or PNG that is added to the TextView right? Can someone please put me in the right way? Even if I just know What "type" are they (png, paint, canvas, etc...), I could make my own way.
Maybe make java add an image view with the image in your drawable folder. Don't know how this would work but try somthing.
I want to create a nine-patch image and use that in my App but I don't know how to create it?
I've searched through the Android source code on the Web and I can't seem to find any examples of this. I need a tutorial so that I can understand the process.
I have searched the best and the simplest answer to make 9-patch image. Now to make the 9 patch image is the easiest task.
From HERE you can make a 9-patch image for all the resolutions - XHDPI,HDPI,MDPI,LDPI in just one click.
Let me know if you have any queries, and do upvote it, if it was helpful to you.
I just found that awesome alternative 9patch editor (by Mikle Garin) and I think it 1000% better than standard one built in sdk:
Editor JAR download link
Editor source code
Editor official page
There's a tool included in the android sdk to create and test nine patch images:
http://developer.android.com/guide/developing/tools/draw9patch.html
You can also create a nine patch file using every gfx package out there ( photoshop, paint.net, ... ) using the creation guideline here: http://developer.android.com/guide/topics/graphics/2d-graphics.html#nine-patch
I've created a tool that allows automatically create 9-patch images from regular PNG images for simple cases where stretchable areas are 1 pixel wide. Here's sample input and output (showed at 400%):
Project page on github
A NinePatch image is a standard PNG image created with Photoshop, Illustrator, Paint... etc.
To add a NinePatch rule to it, just drag/drop it on the draw9patch.bat tool in your Android SDK directory.
IF you don't use the draw9patch.bat tool, you must include an extra 1px transparent border to draw the NinePatch rules with a 1px black (#000000) pencil size before you save it.
Important!!! Save the image with the extension myimage.9.png as a transparent PNG-8/PNG-24.

Although android provides the tool for ninepatch images .Open terminal and go to android sdk -tools path and type ./draw9patch. But this is the best link you can make for all density in just one click.

Displaying an image in an ImageView is quite simple. Check out this family of files from API Demos:
ImageView1.java
image_view_1.xml
ImageView1.java is quite simple: it just loads the xml layout file. You can change the #drawable/... references in image_view_1.xml to point to your own resources and see the effects you get with different styles of ImageView.
I recommend exploring the API Demos code, as it covers a large portion of the Android framework and will give you an idea about what is possible.
