I am trying to create a button that has a custom background in the default state, but that still uses the colors for the pressed/selected states that are particular to whatever device it is running on.

I am trying to remove an ImageButton's background in only the default state. I'd like the pressed and selected states to behave as usual so that they look correct on different devices, which use different colors for the pressed and selected states.
Is there any way to set an ImageButton's background default state's drawable without affecting the pressed and selected states?
I've tried to do this with a selector, but it does not appear to allow you to use the default drawables for some states - you have to set all the states yourself. Since there's no API to retrieve the device's default pressed/selected drawables, I don't know what to set the pressed/selected states to.
I also tried getting the StateListDrawable object for the button that the system creates when you are not using a selector and then modify it change the default state. That didn't work either.
I seems that on Android, if you want to change the drawable for one state of a button, then you must set all the states, and thus cannot preserve the default drawables for the other states. Is this correct?
I want to use a Button in my android app but I want to customize how it looks. However, I want the highlight and selected colors of the button to be the same as the default colors (i.e. the dark and light orange gradients, or whatever the theme color supplies).Is there anyway to get the default highlight/selected drawables and to use that as the fill for my buttons on the selected and highlighted states?

View 2 Replies View RelatedMy app was built on the Android 1.5 platform. I'm in the process of bumping the APIs used to 2.1 . I am still leaving minSdkVersion=3 / targetSdkVersion = 7 in order to support older platforms.
I've made the required drawbles-hdpi / -mdpi - ldpi-v4 folders. Everything is looking great across various AVDs of HVGA/WVGA shapes and sizes.
Everything, except my tabs.
In AVDs running Android 1.5 and 1.6, my tab background colors are appropriate: http://www.shelvesforandroid.com/1p6below.png
However, for platforms running 2.1 and above, something seems to have gone awry:

Notice that the unselected tab color is correct, but the selected tab looks like it's just bleeding the same color as my images.
What can I do to fix this? Enforce the background color to be the same as 1.6-era ?
What is causing this tab color change?
I have a custom component that I want to give the same colors as a TextView.That is, I don't want to copy its colors, I want to get the default background and foreground colors, if there's such a concept on android.
View 1 Replies View RelatedDoes anyone know how to tell when the headset button is being pressed? I'd like to support the usb headsets and possibly bluetooth headsets. My app is a media player and ideally, I could register it somewhere so that if no app that uses the headset button has focus it button press would act as a play/pause command in my app. If the phone is ringing or a call is in progress, I'd like to be sensitive to that and let the button do what it normally does: pickup and hang up calls. we've been trying to chase the button down using this: Intent Filter headset Filter = new Intent Filter (Intent.ACTION_HEADSET_PLUG); headset Filter.addAction ("android.intent.action.HEADSET_STATE_CHANGED"); headsetFilter.addAction("android.bluetooth.intent.HEADSET_STATE"); headset Filter.addAction ("android.bluetooth.intent.HEADSET_STATE_CHANGED"); headset Filter.addAction ("android.bluetooth.intent.action.MODE_CHANGED"); headsetFilter.addAction("android.intent.action.MODE_CHANGED");

View 1 Replies View Relatedi have an app widget that has a couple of buttons on it, and in my onUpdate() call, I am hooking up the buttons to do something when you press them
RemoteViews remoteViews = new RemoteViews(context.getPackageName (), R.layout.appwidget); remoteViews.setOnClickPendingIntent(R.id.Button1, button1PendingIntent); remoteViews.setOnClickPendingIntent(R.id.Button2, button2PendingIntent);
The problem is that when I click on button2, it sends the button1 pending intent. i think that's because it's reusing the pending intent. http://groups.google.com/group/android-developers/browse_thread/threa. "If the creating application later re-retrieves the same kind of PendingIntent (same operation, same Intent action, data, categories, and components, and same flags), it will receive a PendingIntent representing the same token if that is still valid, and can thus call cancel() to remove it." So then the question is, how do I communicate which button was pressed?

View 3 Replies View Relatedi want to change the background-color of a button using a selector-xml-file. My approach is basically the one from the example at the bottom this page: http://developer.android.com/guide/topics/resources/color-list-resource.html.But if I try it with android:textColor as described in the above link it works fine. So it has to be the background issue. I don't want to create a 9patch-png if it's not necessary (basically i just need a "clickable" rectangle so i use a button with a colored background)

In an activity, how do detect the fact that the user pressed the home button?
View 6 Replies View RelatedI have an activity that contains several user editable items (an EditText field, RatingBar, etc). I'd like to prompt the user if the back/home button is pressed and changes have been made that have not yet been saved. After reading through the android documentation, it seems like this piece of code should go in the onPause method. I've tried putting an AlertDialog in the onPause however the dialog gets shown and then immediately tears down because nothing is there to block the pause from completing.

Basically I have created a blackjack game (first using just java) and it falls under an infinite while loop (this is so that the deck data is kept and everything works well. So first it deals the cards and then it needs to wait for either the hit button (which is displayed) or the stand button (which is displayed) to be clicked. I initially did this with a while loop that would keep checking if buttons were hit (basically when a button was hit, a static int would change and stuff would occur). However this just causes the droid to freeze up (thus far anyway) and also not refresh. So please someone tell me there is some way I can have my method pause until a button is pressed? I also need to know the proper way to use invalidate() so that my textviews, pictureviews and such can be updated as the methods change them.

On my Droid X, all system buttons and lists, when pressed, are a bright red color. I want to find out how I can change this color.

View 5 Replies View RelatedI have an xml page with 3 buttons on all leading to similar xml files. However, the second and third buttons only respond if the first has been pressed (and then you go back a page and press another). If I reverse the order of the buttons in the java file, which ever button is listed first is the one that has to be used befor the others.
Here is my java for the buttons:
package converter.units.kitchen;
import android.app.Activity;
import android.content.Intent;

the rest of the app has no errors and functions correctly.
I have noticed while working in the emulator that whenever i get out of my app via any method other than pressing the back button, my toggle button (if pressed) will have its state saved and return to that state when i return to the app. im guessing its because its value gets saved in a bundle and reloaded when i return. when i leave the app via the back button, this does not happen and the toggle is always off when i return. is there any way to get the value of the toggle back if the user leaves via the back button, without having to save the value in a db table? alternatively, if my apps notification is in the status bar, i can be confident that the toggle should always be selected, so if there is no way to save the state, is there a way to find out if my apps notification is currently being displayed? then it would be easy to just set the toggle each time via a quick check of the status bar.
