View 2 Replies View RelatedIm 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?

For example:
I have a view with a red background color. The background color of the view changes to blue. How can I do a smooth transition between colors?
If this can't be done with views, an alternative will be welcome.
When we expand the notification expanded view ,we get a default white background with small squares. how can i change this white background to some other color.

View 2 Replies View RelatedI 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.
In my project I'm Multiple choice list....in this all text view in white color...i want to change text color. in program I'm use simple xml main.xml
<?xml version="1.0" encoding="utf-8"?> <RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ffff00"> <List View android:id="@+id/android:list" android:layout_margin Top="2px" android:layout_marginLeft="2px" android:layout_marginRight="2px" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1"android:background="@drawable/shape_1"android:listSelector="@drawable/shape_3" android:textColor="#ffff00" android:layout_marginBottom="44px" /> </RelativeLayout> I'm ListActivity class setContentView(R.layout.main); setListAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_multiple_choice, GENRES)); listView =getListView();listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
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?
I'm trying to set the background color of a View (in this case a Button).It causes the Button to disappear from the screen.What am I doing wrong, and what is the correct way to change the background color on any View?

View 1 Replies View RelatedThis 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 RelatedI 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.
View 3 Replies View RelatedI'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.

View 1 Replies View RelatedI have developing list as public class AddSwitch extends ListActivity.
View 4 Replies View RelatedI'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.
View 7 Replies View RelatedI made a custom widget (which is just a composite like):
<LinearLayout> <TextView> </LinearLayout>
this widget is focusable and reacts to touches. I'd like it to change its background color to the default system highlight color when the user scrolls to it, and have it blink when the user taps it (just like an element of a ListView does).
I can add an OnFocusChangeListener for when the user scrolls to it, and in the handler do the changing of the background color.
How would I add the 'blinking' behavior though when the user just taps it with a finger? I did something like this as a test code...
this is just a guess. Is there a correct way of implementing this behavior?
I have a subclass of android.app.Dialog and because I am using a light theme, the dialog title comes out as Black on a dark background which is hardly readable. This leads me to the question: how do I change the Dialog title background or foreground colors? Can I do this via a theme? Which property will it map to?
