When i launch Activity A, the screen goes black, then dark-gray. Then A launches B, and the screen goes black and dark-gray again. Is there a way to set the default background color to black? Activity A has no screen, its just a stub that calls B.

View 2 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 RelatedHow 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.
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?
View 2 Replies View RelatedI've noticed that changing the background color of an android widget (f.ex. Button or TextView) by program:
myButton.setBackgroundColor(Color.BLUE);
makes it to loose its 3D shape, border, and shadows effects, and then appears like a ugly flat square. What am I missing?
Sorry for the very naive question but I couldn't get it right although tried for a time.

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 change the color of a horizontal progress bar (foreground). I came across this example and am trying to model my XML file off it. However, I get a compiler error at the following statement: myProgressBar.setProgressDrawable(R.drawable.progress_horizontal); The error is "The method setProgressDrawable(Drawable) in the type ProgressBar is not applicable for the arguments (int)." I believe the reason is inside the R.java file I see the following line:..................
