I have a RadioGroup which consists of five RadioButtons. What I'd like to achieve is setting an image as a RadioButton argument. So far found this way:
radio0.setBackgroundResource(<drawable ID, int>);
but it gives something like this (descriptions "isSelected" added in an image editor):
Is there any way to programmatically set background properties and move the image to the right?
Or maybe there is another way to set an image next to RadioButton instead of using it as a background image?
I'm interested only in programmatical solutions, as the RadioGroup is cleared up and filled again during loop work.
A friend of mine helped me to figure out this issue.
Instead of the code line posted in the question I use this one now:
radio0.setCompoundDrawablesWithIntrinsicBounds(0, 0, <drawable ID, int>, 0);
The third parameter corresponds to android:drawableRight XML parameter. More on this: click.
Thanks to it a picture is set to the right of the RadioButton and finally it looks like it should.

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 have some intent with set of TextViews and a Button. If user clicks the button and there is some error I want to change look of one TextView. E.g. change the border to red and make font bold. I wrote a style for it but I have not found method setStyle on the TextView. After some self study I realized that Android does not support setting the style programmatically. There are some workarounds, when you create the intent source. But my intent already exists, it seems odd to recreate it.
Could you tell me the proper way?
use the workaround and create the TextView again
forget the styles and use java methods to decorate existing TextView
something else
Changing the style of the textview directly does not work as you know. But you can create a second textview with other styles in your layout, which you can show up if needed.
Just add this xml attribute android:visibility="gone" to the second textview, so this second textview is not displayed at first, but available.
When you now want to change the style of your textview, you simple need to swap the two textviews by hidding the first one and showing the second one
textView1.setVisibility(View.GONE);
textView2.setVisibility(View.VISIBLE);
I used these two answers to make it work:
https://stackoverflow.com/a/5488652/1639556
https://stackoverflow.com/a/14195090/1639556
and the code is:
ViewManager parent = (ViewManager) unknown.getParent();
parent.removeView(unknown);
TextView newUnknown = (TextView)getLayoutInflater().inflate(R.layout.tvtemplate, null);
newUnknown.setId(unknown.getId());
parent.addView(newUnknown, unknown.getLayoutParams());
unknown = newUnknown;
You can try using setTextAppearance() on the textview. The link is: setTextAppearance
Your style will need TextAppearance.SomeThing.SomeOtherThing as the parent.
Use R.style.YourStyleName as the integer argument.
I want to remove focus in gallery for a selected item. I am getting an output like this, Here is an image :
Here first item selected. So it is looking darker than 2nd image. I want to display an image as it is not focused or selected.
Please anyone help. I'll really appreciate that.
Thanks
Create a statelist drawable (see http://developer.android.com/reference/android/graphics/drawable/StateListDrawable.html) and customize the "selected" state to whatever you want there, in your case transparent . Then you provide this drawable as the background for the item.
EDIT:
Also look in to gallery
android:unselectedAlpha
try to apply below two property in your xml to your gallery.
android:focusableInTouchMode="false"
android:focusable="false"
you can use something like
View.clearFocus()
LinearLayout myLayout = (LinearLayout) activity.findViewById(R.id.my_layout);
myLayout.requestFocus();
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.
How would I modify the .xml and .java files so that a RadioButton shows one image when selected and another image when not selected?
Example for RadioButton I am learning from: http://www.androidpeople.com/android-radiobutton-example/
Here is an example that uses StateListDrawable and RadioButtons, and seems to do what you want.
you need to set its android:button property to a StateListDrawable that has at least two states: selected=true and a default one (unselected).
