Android :: Resetting The Background Color Of View

Sep 8, 2010

I'm trying to restore the background Color of a View. I have several selectable Views. When the user clicks one of those Views, the following code is executed and the View becomes Yellow:

View newSelection, previousSelection;

...

if(previousSelection != null) {
previousSelection.setBackgroundColor(Color.BLACK); // problem here
}
newSelection.setBackgroundColor(Color.YELLOW);

However, I want to reset the color of the previously selected View. However, I do not know which color it was (I'm setting it to Color.BLACK in the above code). I was not able to find a getBackgroundColor or similar method in the View class. If I had it, I could save the previous color and just put it back when the new View is selected.

Android :: View Background Color Animation

Nov 16, 2009

I was wondering if someone has a good answer to this.I am looking for a better way to animate a background color transition from on color to the next.Currently, I have two views, vCurrentColor which lays on top of the vNextColor, in a FrameLayout. I then animate the alpha of the currentColorView to zero. At the end of the animation I swap the positions of the views and repeat the process.

Android :: View On Press Onpress - Change Background Color On Press - How Do Show That The View Is Being Pressed

Jan 5, 2010

I have, for the time being, a custom view with a 9-patch image as a border.

That custom view is placed three times in a LinearLayout, so it looks like this:

+------------------------+
| CustomView |
+------------------------+
| CustomView |
+------------------------+
| CustomView |
+------------------------+

I have attached a click event listener to the View, so it is clickable. But then I click it, I cant see that I am clicking it - there is no change in color.

So, Im thought that I'd attach a "onPress" listener, and then change the background of the view but I couldnt find such a listener.

So, the question is - how do I create the behaviour on the View so I can see that it is being pressed? this is normally done in Android with a green background to indicate that it is now being pressed.

Android :: Changing Background Color On Selected List View Item

Apr 17, 2009

Im trying to change background color when an item is selected. Something like using a color selector, but actually it crashes. I've created a list_selector.xml inside /res/color/.<?xml version="1.0" encoding="UTF-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"><item android:state_focused="true" android:color ="@ color/ plain_yellow"/><item android:state_pressed="true" android:state_enabled="false" android:color ="@color /plain _yellow" /><item android:state_enabled="false" android:color="@color/ plain_yellow" /><item android: state_active="true" android:color="@color/ plain_yellow" /><item android:color="@android: color/ transparent" /></selector> plain_yellow is a color i've defined in /res/values. I've tried to assign that selector programatically and using the xml, but the app crashes. Am i doing something wrong?

Android :: Views And Their Child Views - How To Avoid The Ugly - Boxes - When Child Views In A View Has Another Color Than Background

Jan 6, 2010

I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.

The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.

The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.

What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.

Android :: Android - Color State List Resources - Specify A Background Color

Oct 17, 2010

To give the user of my app an indication which field currently has the focus I am trying to change the background color of some of my fields depending on the current state, however, I am having troubles understanding Androids Color State List Resources:

There is this example at the bottom of http://developer.android.com/guide/topics/resources/color-list-resource.html. If I try exactly the same, i.e. if I want to adapt the textColor , things do work. However, if I try an only slightly different thing, namely to adapt the background color, things do not work and I don't understand why? Why is this so inconsistent?

To make it simpler to understand what I am trying to do, I append my misc. .xml files:

The AndroidManifest.xml file:

CODE:.........

If I run this as shown here, it works, i.e. I get a button whose text color changes depending on whether the button is focuses, pressed, etc.

If I uncomment the lower button, where I just flipped the attribute values for textColor and background I get an exception, stating

... <item> tag requires a 'drawable' attribute or child tag defining a drawable

What the heck am I missing here? Why is that color state list acceptable as a text color but not as a background color? How does one specify a view's background color depending on the view's state?

General :: Galaxy Nexus Keeps Resetting Background When Restart Phone

Jan 15, 2013

Every time I reboot my phone it keeps changing my background back to the same stupid image below. I think I'm probably going to go insane if I see this stupid grass anymore. The picture isn't even on my phone (anywhere I can see, obviously.) I don't know what to do. I've flashed several Roms, done several factory resets, changed it to a million different images/live wallpapers.

Android :: Selector On Background Color Of TextView

Aug 28, 2010

I'm attempting to change the background color of an Android TextView widget when the user touches it. I've created a selector for that purpose, which is stored in res/color/selector.xml and roughly looks like that:

CODE:................

The clickable attribute of the TextView is "true", in case that's of interest.

When I assign this selector to a TextView as android:background="@color/selector",

I'm getting the following exception at runtime: ERROR/AndroidRuntime(13130): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable

When I change the attribute to drawable, it works, but the result is looking completely wrong because the IDs appear to be interpreted as image references instead of color references (as the "drawable" suggests).

What confuses me is that I can set a color reference, e.g. "@color/black", as the background attribute directly. This is working as expected. Using selectors doesn't work.

I can also use the selector as the textColor without problems.

What's the correct way to apply a background-color-selector to a TextView in Android?

Android : How To Set Background Color On Open GL ES Droid?

Sep 27, 2010

I am currently playing about with lesson 08 here http://insanitydesign.com/wp/projects/nehe-android-ports/ I would like to change the background colour from black to white. In order to do this at the start of onDrawFrame() I have called gl.glClearColor(1.0f, 0.0f, 0.0f, 0.0f); This does indeed set a white background screen, but also results in nothing else showing up on the screen! Clearly this is therefore an incorrect method, but why, and how do I fix it?
