Android :: Changing Background Color On Selected List View Item
Apr 17, 2009Im 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?

Jan 28, 2010This is my first app so finding my way around bit by bit and have been experimenting a little and would like to change the background colour to a colour from a list.Currently it loads a white background specified in strings.xml <color name="all_white">#FFFFFF</color> This is used in main.xml:android: background=" @color/all _white"Ideally I would like to change the colour in OnCreate() to a colour of my choice. I have tried setBackground Drawable but it doesnt seem to work?This is my code:public class TestActivity extends Activity double dimValPercent = 100; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super. onCreate (savedInstance State); setContentView(R.layout.main); SetDimLevel(dimValPercent);SetBackground(); return;}public void SetBackground(){getWindow().setBackgroundDrawable( new ColorDrawable (color.all_blue) );

View 1 Replies View RelatedAndroid :: Changing Background Color Of ListView Items?
Feb 7, 2010How can I change background color of ListView items on a pair-item basis. When I use android:backgroundColor in the ListView item layout I can achieve this, however the list selector is no longer visible. I can make the selector visible again by setting drawSelectorOnTop to true but then the selector overlays the whole item.
Any ideas how to change those background colors and keep the selector?
I would rather not change the selector itself.
Authors of GMail application have managed to achieve exactly this so it's definitely possible.
Android :: Android - Color State List Resources - Specify A Background Color
Oct 17, 2010To 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?

View 3 Replies View RelatedAndroid :: Resetting The Background Color Of View
Sep 8, 2010I'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 :: List Item Background Is Changing On Scroll
Mar 10, 2010I have a background color applied to a ListView but everytime the list is scrolled the background color changes back to the system default (black). When the scrolling stops the color goes back to @color/window_background.The style is applied in AndroidManifest.xml:<activity android:name=".event.EventList" android:theme="@style/CKButtons"></activity> and my ListView looks like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<TextView

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="@string/eventlist_no_items"/>
</LinearLayout>How can I prevent this from happening?
Android :: View On Press Onpress - Change Background Color On Press - How Do Show That The View Is Being Pressed
Jan 5, 2010I 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.

View 1 Replies View RelatedAndroid :: Changing 9 Patch Background On List Item In Runtime Doesn't Always Redraw
Jun 1, 2009I have a ListView containing a few different type of items, all having their own background image and font color. In my first implementation I implemented each type of item as its own layout with the background image etc defined in XML (and implemented Adapter.getView() so that it only reuses convertView if it's of the correct type). This works fine but the performance is not that great while scrolling since I'm inflating quite a few Views due to convertView mismatches, so instead I tried using the same layout for all items (to benefit fully from convertView reuse) and changing the background image and font size in runtime. I even keep the three background Drawables I need as members to save time decoding them from a resource for each item, and call View.setBackgroundDrawable() from Adapter.getView(). The problem is, sometimes the 9-patch is not correctly wrapped around the content of the list item when using this approach. While scrolling it usually looks correct but when the scrolling stops, or sometimes when I just tap anywhere on the list, the background 9-patch of some large items starts flickering and is either cropped or resized to its original PNG size rather than stretched to wrap the content.
First of all, I suspect this is a bug? Any ideas why this happens? Could it be that the View is not always measured to reflect the changed content when the 9-patch is applied? I have tried adding an extra call to View.invalidate() but it doesn't solve the problem. Second, does this approach sound reasonable at all, or how should I go about to optimize this scenario?

Android :: Android List View Background Colors Always Showing Grey

Inside the Adapter (in the getView(int, View, ViewGroup) method) I'm setting the background color of the View using setBackgroundColor(int). The problem is that no matter what color I set the background to it always comes out a dark grey. It might also be worth noting that I'm using the Light theme.

Nov 3, 2010I am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).
View 1 Replies View RelatedAndroid :: Views And Their Child Views - How To Avoid The Ugly - Boxes - When Child Views In A View Has Another Color Than Background
Jan 6, 2010I 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.
