Creating a game in Android using multiple Buttons to display an image from the drawable folder. I want to change the button to a different image after the button has been clicked on.
Here is the button code:
CODE:.............
I can't find anything about how to change the actual image of the button. You can change the color of the button by using the following code in the java file: b36.setBackgroundColor(0xAA00AA00);
In the emulator on touching my button I want its image to be changed. I just want to bring my mouse pointer there, without click. This can be observed for other keys of the emulator. On touch a blue image appears on the keys.
View 2 Replies View RelatedCan anybody please guide me how to write the code for opening the new image after clicking the imagebutton in android. I have tried something like this:
package com.example.imageButton;
import android.app.Activity; import android.os.Bundle;
import android.view.View; import android.widget.ImageButton;
public class imageButton extends Activity {
private static ImageButton seqIBtn;//these are the three imageButton private static ImageButton vidIBtn;private static ImageButton infoIBtn; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); seqIBtn = (ImageButton) findViewById(R.id.btnSequence); vidIBtn = (ImageButton) findViewById(R.id.btnVideo); infoIBtn = (ImageButton) findViewById(R.id.btnInfo);}
Trying to the do as the title describes with the following code, but it doesn't seem to work. It just does nothing once i have altered the keyCode. Do i have to do something to the event?

i've got this simple layout in a file derived from Activity
<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dip" > <ImageView android:id="@+id/photo" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </ScrollView>
i'd like to change the imageview contents dynamically. which method do i need to overload - again this class is derived from Activity.
I have created an activity that extends ExpandableListActivity class.
I want to customize the look and feel of my expandable list activity. I have achieved the customization of list selectors.

I am running into a very weird thing. I have an ImageView, and when I call setImageURI with an image, it seems to change the size of the image view.
CODE:..............
The default image is 195 x 195, i am trying to set the image to be 200 x 200, after setting the image using setImageURI, i get the dimensions back and it says it's 48 x 48.
I have tried a bunch of different android:scaleType parameters, and I couldn't find anything that worked.
I also tried explicitly setting the size (layout_width="200px") and it seems to work.
I am using a LinearLayout to display some Text and image. I have the images at drawable/ and i am implimenting this with ListActivity with some onListItemClick functionality. now i wants to change the image for the rows which are processed by onclick functionality to show the status as processed. can some one help me in this issue to change the image at runtime.
The following is my implimentation.

I thought to add the field to DB. but i was unable to know how to change the image with code. can any one provide me an example for drawing image with code and change it based on a condition at runtime.
Over the past few days I have been trying to implement custom widget functionality. In this case I have instantiated a RemoteView containing some TextViews and an ImageView in one application's BroadcastReceiver. The BroadcastReceiver receives the intent signaling it to send the RemoteView to the calling application. When the calling application receives this RemoteView it uses apply to inflate the view properly and display it on the screen.
The problem occurs when the activity changes, the inflated RemoteView occasionally has information disappear. One time the image even changed into another image from a drawable located in the BroadcastReceiver's application. Has anyone else experienced a similar problem and/or have a solution?
I have looked at posts concerning ImageViews in widget use and orientation changes. Is this problem related? I am not entirely sure. I am currently running Android 1.5 SDK and am not able to upgrade for this side project of mine.
Is there a way to set a separate picture for you lock screen? If so, how?
View 1 Replies View RelatedI am having an EditText. If i specify image for the EditText in the layout XML file (android:back ground) it looks different and looks different when i specify it at runtime EditText et = (EditText)find ViewById (R.drawable .et1) ; et.setBackgroundDrawable (Main.themes.getDrawable (EDRAWABLES.EditText BackgroundImage )); Both codes point to the same image. When i specify the image at runtime , the EditText leaves a margin at the top and bottom of the cursor in the edittext which does not happen when i do it in XML. I have attached the screenshots of both images. Top image is the one drawn from XML and bottom one is given at runtime. I am not getting the difference ? Actually i am facing similar problems with other Widgets too if i change the logic of specifying the drawable at runtime and not at compile time.. Is this the default SDK behaviour?

View 2 Replies View RelatedYou know when you call someone who doesn't have a photo linked to their contact it displays the green android guy. Well I really like what forum member sprint fun did with his avatar by making it into a OSU buckeye. I would much rather see that image rather then the green default android guy. Sprint fun has already said I could use the image, but I have no idea how or if its possible to set it as the default image for callers with no photo linked to their account.

View 1 Replies View RelatedWondering if I'm going about this the right way or not. I have 3 buttons on my screen (Restart, Previous, Next). When the view loads it shows the first image which is fine. When I click the "Next" button I want it to load a second image and so on for up to 9 images. If I click the "Previous" button it should go back one image. Clicking "Restart" should go to the first image. I have the Restart one working. I'm having trouble with the Next button because it only shows the second image (I think because my "a" variable is initialized at 0).
View 1 Replies View RelatedI just bought a HTC Legend, and still getting through the n00b curve. I have tried Googling much as I can and now learned to live with issues such as no task manager and inability to actually terminate applications after use. Contrary to my old school Windows mentality I am going to trust the OS to manage the RAM and Battery. Better hold up!
Now I have let that issue go, I was wondering is there anyway to change the wake up key from power button to any other button. This is when the phone goes to sleep and to wake up I'd like to be able to press the Home button and get the screen to light up again. I have gone through preferences and was unable to find anything to change this. Any help please?
I need to have a grid (created by program, not by xml) of equally sized buttons. They display text in different sizes. The problem is that when I change the text size to a smaller size, then the button automatically resizes to be smaller than the others.

View 3 Replies View RelatedI would like to change margin of my buttons in application. Suppose I have 5 buttons like this in a linear layout, one below d other. When I focus on a button, its width should increase (which I know how to handle) and at the same time, width should increase linearly towards both left and right. i.e. If the current width of the button is 250 with x co-ordinate as 50 (that means button's left is 50 and button's right is 300), when I focus on the button I should get x co-ordinate as 75 (left = 25 and right = 325). How to change the margin/x co-ordinate of the button?
View 1 Replies View RelatedI was wondering if it is possible to use a similar approach to change the style attribute of an element using the same (or similar) technique.Or, if that is not possible, how can the style attribute be changed during runtime (there is no such thing as button.setStyle(R.style.button)).
View 2 Replies View RelatedI Just installed the Dolphin browser instead of Steel as I was using before. So uninstalled Steel, but have a little problem now. When I press the search button on my home screen and search for anything, it opens the default browser and searches, and not Dolphin. How do I change this? Thought it would ask for which app it needed to execute the order with, as it did at other places it would go online, but not here. Has been in the manage applications and delete the default browser to be default, and inside settings in the dolphin browser and the check it to be default, but it does not work.

Right now, I have an image that spans 500 x 200 (not really, but it works). Over top of that image, I have two buttons equal to 50% of each side.

I'd like to know how to make a button out of a PNG and display it on my canvas (using drawBitmap?). When I click on this button, it will take me to a new activity. All this will be in the onClickListener. So, how do I take a PNG, make a button with it, and draw it on my canvas?

Is there a way to create Buttons that contain both an Image and Text (image on top text below or image left and text right)? And how can this be done within a xml layout file? For example, the application 'Pkt Auctions eBay' (see Android Market) has these type of buttons.So far I have tried and googled all over and found nothing on the matter. Help is much appreciated. Thanks in advance.
