Android :: Can I Programmatically Generate Focused Image For An ImageButton
Mar 6, 2010
I'm porting an application from iPhone to Android. The iPhone app has artwork for some dozen or more buttons in their normal and pressed state. That translated over just fine to Android. However, we of course currently don't have any images for the "focused" state.
Besides the work involved in creating all these focused button images, we're not sure exactly what color to set the focus too. Selection color varies from phone to phone, etc. We'd have to come up with some neutral "white glow" of some sort I suppose. Then the idea struck -- could we programmatically render a focus images for the buttons based on the current selection color? Have folks been doing anything like this in the Android dev community? Can you point me to some examples. A net search didn't turn up anything too useful, though perhaps I searched on the wrong keywords.

A 'Button' view comes up with text, while the 'ImageButton' widget comes up with an image but no text, is there a way to relatively easily (e.g. method calls, say), either:
1. Add text to ImageButton (like those buttons that appear in menu item/via the physical menu button)?
2. Add an icon/image to a Button?
without resorting to constructing a new button class? I.e. I could put text within the image, but then I can't use Localization properly/effectively.

I want to set image dynamically on the ImageButton in android. However, i have more than 200 images. what would be the good solution for that?
The best idea is that i can use the name of image to call different images. i.e. imagebutton.setImage("/res/abc.png");
however, it seems to me that it is not trivial to do so..

I've set the background image of a custom ImageButton I am building, as well as setClickable(true) and setFocusable(true). The button is able to receive focus when I navigate with DPad/arrow keys in the emulator, however, it does not flash orange when it has the focus. It does not appear to change at all when it has the focus, in fact. When I remove the background image, however, the ImageButtons hold orange when they have focus.
What do I need to do to be enable an ImageButton with a custom background image to flash orange when it has focus?

I want to create an Android ImageButton in the xml file with a background image, and a smaller icon on top of that, right in the center. For some reason, it's not obvious how to do it, and documentation is no help.code...
However, no matter what I try (putting "wrap _ content" instead of absolute numbers on layout _ height and layout _ width, the icon remains in the top left corner of the button. If, however, I have no background image (i.e. a system default white button), the icon does go into the center. The button also goes into the top left corner when I use a color instead of an image for the background.
Why does this happen, and how would I actually get the behavior I want-- that is, a background image with the icon in the center?

I'm trying to make it so that as long as a user is touching the button, it shows one image, and when the user releases the button, it goes back to a default image.
I'm trying to use a selector to make this happen:
CODE:...............
I've tried a few things with the selector, but it always produces the same behavior: the button starts out with the default image, then I press it and it changes to the "record_on" image and it never goes back to the default image when I let go.
Is there a way to get this kind of behavior with an ImageButton, or should I be using something different?

I have a widget on my home screen with several ImageButtons which have default background images. Through the configuration activity, I can change the image on any of the ImageButtons. The problem is that when the screen is rotated, the image on the ImageButton disapears and it changes back to the default image.
I don't know why this happens or how to fix it

I have a png file in my res/drawable-ldpi folder. I'm working in Eclipse with the emulator, but I've tried this on my 2.2.1 Android phone and I get the same behavior. I have an ImageView and I want to set the src programatically, based on a database call. If I just put
Code:
src="@drawable.norusdpyr"
in the Activity's XML file, the file displays fine. BUT, if I put
Code:
String imageresource = "R.drawable." + parsedData[4].toString();
chart.setImageURI(Uri.parse(imageresource));
where parsedData[4].toString() = "nor_usdpyr" I don't see anything. I've also tried
Code:
String imageresource = "android.resource://" + getPackageName() + "/R.drawable." + parsedData[4].toString();
chart.setImageURI(Uri.parse(imageresource));
and
Code:
InputStream is = getClass().getResourceAsStream("/drawable/" + parsedData[4].toString());
chart.setImageDrawable(Drawable.createFromStream(is, ""));
and
Code:
String imageresource = "R.drawable." + parsedData[4].toString();
File file = new File(imageresource);
chart.setImageDrawable(Drawable.createFromPath(file.getAbsolutePath()));
and
Code:
Context context = getApplicationContext();
int ResID = context.getResources().getIdentifier(imageresource, "drawable", "com.KnitCard.project");
chart.setImageResource(ResID);
finally,
Code:
chart.setImageURI(Uri.parse("android.resource://" + getPackageName() + "/R.drawable.nor_usdpyr"));
doesn't work.
None of these work. What am I doing wrong?

I have this custom layout:
- LinearLayout
- FrameLayout
- ImageView
- TextView
This layout reacts to click events (using LinearLayout.setOnClickListener()) and is made focusable using android:focusable="true" in the layout XML file. This all works fine if you're using the touchscreen, but I'm thinking about users who don't use the touchscreen that much and prefer navigation keys or maybe even don't have a touchscreen. These users won't be able to see when that ViewGroup is focused (although it can be focused using the keyboard).
My question is: how can I make a change in that layout when it is focused (I need to change the android:background of the ImageView)? I suppose I could use LinearLayout.setOnFocusChangeListener(), but I'm thinking maybe there's a better way, using just XML files.

If I set my ImageView to be both clickable and focusable, it works, but I have no way to tell which image is focused. What's the best way to get it to draw an orange border around the view so the user knows it's currently in focus? I tried dropping it in a LinearLayout and setting that to be focusable and clickable instead, but didn't have any luck. Even when I put a margin on it, there's nothing to indicate that it was selected.

A good example of this is either on the Twitter launch screen (the screen with the large icons that is seen when the application is first launch) or even just look at the application tray when you focus an application icon.
Basically I need to highlight an ImageView where the highlight contours to the image within the ImageView and looks like it's a border to that image. I would also like to customize the highlight to have it be a certain color and for it to fade out.

My application opens in Activity A1. None of the views in A1 are focused at startup, until I use the arrow keys to navigate through the views. A button press in A1 launches activity A2. When A2 opens, the first Button in A2 is focused by default. I do not want this happen. What I want is when A2 opens, none of the buttons are focused until arrow keys are used to naviagte through them(just like it is in A1).

If I have a layout with lots of EditText views in a LinearLayout and the user focuses the third one down and flips out the keyboard to start typing, the entire layout is destroyed and recreated through the activity lifecycle. When everything is done, however, the third EditText is given focus again and the user never knows that anything happened and types away.
I am creating a similar layout, but due to the nature of my data, I have to dynamically create the list of EditTexts, mixed with some other views. The default layout has one EditText at the top, a ScrollView with a LinearLayout child (which will be filled with EditTexts later), and some action buttons at the bottom. I fill the LinearLayout with all the EditText fields I need (based on extras passed via intent).
This part works quite well, but the way the activty handles Runtime Configuration changes is broken now (from a UI perspective). Now if the user focuses the third EditText (which was dynamically created via new EditText()) and flips out the keyboard, the layout is destroyed and recreated, but focus is always given to the permanent EditText at the top of the screen.
Is there something I need to do when adding my dynamic views to make sure they can keep focus through orientation changes? is there a way I can work around the issue and force focus to be given to the last view that had it before the change?

I have a TextView inside a LinearLayout. The LinearLayout is able to receive focus, and I want the textColor of the TextView to change when it does. I thought using a ColorStateList would work, but it would seem that the TextView does not receive focus when the LinearLayout does. I know that, because I have tried this code...
And nothing gets logged. I don't want to use an OnFocusChangeListener on the LinearLayout to change the textColor of the TextView, I think this has to be done from XML. The reason for that is because in another activity I have an ExpandableListView with a custom adapter and custom views and Android changes the textColors of the TextViews (from light to dark) inside my custom views when items are focused.

I have encountered a problem with focused text fields in a WebView not showing entered text values.As long as a WebView text field has focus it will not show text or even the blinking cursor.You can select and highlight the text or unfocus the field to see it, but when it gains focus it will not show the text as if the foreground color of the text is white.The simplest code to demonstrate this is below.With the setTheme using a Light background, try typing values into the Email text field to notice that the text is not visible when the field is focused.

I'm using ExpandableListView in my app and one of the complains is that when expanded it's hard to visually distinguish where the child item ends and next group item begins. So I would like to change background of the child list item to the different shade. Brutal attempts that I've made so far were based on directly changing background color and text of the elements inside the child view item but that leads to loss of hovers and highlights. So my question is - what is a good strategy to achieve the above? I tried styles and selectors but what really bums me out - that if I change one thing then I need to add selectors for all combinations of focus/enabled etc. when all I'm trying to do it to overwrite a single thing. Is there a way to inherit parent style and set just a background for non- focused, enabled child item?
