I'm trying to achieve something like that:
I tried to put a TextView on top of it by changing the elevation, but it falls under the floating button anyway, any suggestion? :S (can surely use an ImageButton that looks like a floating button and put a view on top of that, but I wonder if there is a better way)
Have you tried using the xml:
android:src="#drawable/image" //uses a drawable as a background for your button
Or in java, like this:
fab.setImageDrawable(Drawable);

I have a image "myXmlImage" in my .xml file
In the .kt file, I want to paste another "newImage" image as well as a little text "newText".
myXmlImage.setImageDrawable(newImage.drawable)
myXmlImage.imageMatrix = newImage.imageMatrix
So far it has been working very well and the new image is in place.
I'm completely stuck on how to paste the little "newText" into it
Any ideas will be greatly appreciated, thanks in advance.
Perhaps there's more than what you've described here. But if those are really your only specifications, then what you're asking for is really easy.
I'm assuming that your xml file has a root of ConstraintLayout. If it doesn't, then you're going to either want to change it or at least wrap your ImageView inside of a ConstraintLayout.
Use the layout editor to place a TextView inside of your ImageView (NOT AS A CHILD; when I say "inside", I mean spacially inside). If you haven't used the layout editor very much, it might take you a couple of tries to place the TextView inside. Don't just drag it into the ImageView as if it were a child. Drag it and drop it under the ImageView inside of the ConstraintLayout and then use little circles on the sides to attach it to the sides of the ImageView. Don't forget to set the text of the TextView as "".
(I'm not actually sure if this step is necessary because I don't know what the default background of a TextView is, but I do it out of habit.)When you're done placing that TextView inside of the ImageView, go the code of your xml file and use android:background="#00FFFFFF" (or maybe somewhere in your project you have either a transparent background drawable or a transparent #color that you can reference by name).
I'm sure you know the rest. Just give that TextView an Id like newtext and inside of your activity retrieve the view: newText:TextView=findViewById(R.id.newtext). And then set the text: newText.text="new text".
I need to add a scrollable android TextView, which will show alot of text.
I want to achieve this kind of effect:
But I found no way of doing so.
Is there any good way of doing it?
Thank you!
try below properties to TextView
android:requiresFadingEdge="vertical"
android:fadingEdgeLength="32dp" //To change the gradient overlay height
The most convient way of doing this is creating a drawable. You can either make your own image in the image editing software of your choice or create a GradientDrawable. Make sure the colors go from white to transparent. Then place this drawable on top of the textview near the bottom.
I'm creating a custom implementation that extends android.support.v7.widget.AppCompatButton. I am using setBackground(Drawable) in the button's constructor to put an image on the button, but want the image to be centered on the button with a little padding. How can I do this?
It sounds like you should be using ImageButton instead of Button. If you do so, you can take whatever image you'd normally use and create an Inset Drawable from it, and then use that as the src attribute of your ImageButton.
Say you have a drawable res/drawable-mdpi/mydrawable.png. You could create res/drawable/mydrawable_inset.xml as follows:
<inset
xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="#drawable/mydrawable"
android:insetTop="100dp"
android:insetLeft="100dp"
android:insetRight="100dp"
android:insetBottom="100dp"/>
Here's a layout that includes one ImageButton with just #drawable/mydrawable and a second with #drawable/mydrawable_inset:
I want to create icons as something like this image or something like on the homepage of quickr. If I use custom gridview for this as in this (of course in my case I need the text below the image ), then adding listeners to that would be difficult I guess. Should I use buttons for that with the image and text below that provided the background is transparent? If so which layout I need to use? Or is there any icon view facility in android like other views such as button and imageviews, so that we can modify as per our requirement.
You should use button for that.
<Button
android:id="#+id/btnIconName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableTop="#drawable/iconimage"
android:text="IconTitle" />
For showing icon you should use android:drawableTop and for iocnTitle use android:text
Property.
I hope my answer is helpful to you.
GridView will be the best option to do this and why dont you ask your graphics guy to add text with image.
I am designing something that will have a homepage close to the Google+ android app.
I'm having trouble figuring out the best way to do this? Should I create a button with text and set the background as the image? Should I create an image with the text already programmed in the actual picture or should I program the text and picture to be buttons.
Any suggestions from you guys on past projects?
You can use a Button with text to whatever you like and then place the image for that button above the text (using android:drawableTop)like so:
<Button
android:id="#+id/imageButton"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="Photos"
android:drawableTop="#drawable/button_image" />
replacing buttton_image with your actual image. If you want the image in a different position (i.e. below text etc) use:
android:drawableLeft
android:drawableRight
android:drawableBottom
This would be how I would and do do it...
Since I am a newbie in android development I may be wrong but I suggest why not use a Grid View with each grid item haaving a textview and imageview.
My suggest to layout:
If you want to try something new in Android 4.0 , you can try GridLayout to layout , it can reduce the complicate of the nested layout , check out the blog about GridLayout:
http://android-developers.blogspot.com/2011/11/new-layout-widgets-space-and-gridlayout.html
You should write Buttons this way: http://developer.android.com/resources/articles/layout-tricks-merge.html
I normally use RelativeLayout but this is not important.
Write a class myClass extends RelativeLayout and inflate the XML with
LayoutInflater.from(context).inflate(R.layout.myCustomLayout, this, true);
I think this is best practice by Google.
use a regular button and set the android:drawableTop="#drawable/icon_...." value
Having the text burnt into you image is most certainly not the way to go.
One option for you is a GridView. You could also do this through a combination of Image button and scrollview. In my opinion, GridView is best and involves the least amount of code with most flexibility.
Remember that you can replace the button's background image with a state list drawable.
