Android :: Header - Views And Buttons - How To Attach Listeners To Buttons In A Header That Does Not Have Its Own Activity
Jan 6, 2010I have touched on this question here, where Christopher gave an answer to this, but I dont really get it so I thought its time to make it a real question, not just a "follow up" =)
As it stands, the application Im writing has 4 different screens:
1. Screen 1 - list of nodes (main screen)
2. Screen 2 - options menu, tableLayout with buttons
3. Screen 3 - navigation
4. Screen 4 - text details on version etc
These screens can be navigated to/from using a "header" View that is placed on top. the header then has 4 different buttons:
+--------------------+
| menu with buttons |
+--------------------+
| |
| |
| |
| C O N T E N T |
| |
| |
| |
+--------------------+
The header is just an XML-file (header.xml) with a few buttons. That header.xml is the included in the Layouts using the include-markup. For example, the main.xml has the line:
<include layout="@layout/header"></include>
The header show up alright, but the question is - what is the correct approach to attach OnClickListeners for the buttons in the header?
Christopher pointed out that you could create an Activity class and do the hooks there, like this:
CODE:............
First, I cant make it work since the method setupHeaderButtons isnt accessible from FirstActivity.
Secondly, is this the right way to go at it?
Android :: Click On Image / Pass Image To Another Activity / Page
Oct 12, 2010I am very new to Android (and Java) originally a C# developer.. and am struggling with the concepts and terminology.
I have been through almost all the tutorials and have decided to start on my first test app.The first part of my app is going to involve using the gallery widget (based on the hello gallery tutorial) to display a load of images. (these images will eventually come from the phones camera, but I will cross that bridge later!) My images are currently stored in the drawable folder in my project.As a first step I want to just have the user click on an image and it pops up full screen, just so I know how to get reference to it, but I am struggling. Evetually I want the user to click an image, then a window/activity(?) will open asking them for a bit of text. This will then be store in sqllite against the image. Code...
Android : How To Add A Background Image To Droid Activity
Oct 12, 2010My goal is to develop a GUI application on top of a background image with buttons in specific places on the image. The first step is to display the background.
The image can be displayed with resources and is described in several FAQs including this one:
how-to-add-background-image-to-activity
It compiles and runs without errors, but the background is black. Here is the main.xml file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/rootRL" xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/background">
</RelativeLayout>
The image has been in png, 9.png, and jpg format with basenames of 'main' and 'background'. It builds but does not display. Making clean and recompiling does not help.
This behavior occurs on both the emulator and on hardware -- an Atmel AT91SAM9M10-G45-EK. The SDK version is 2.0.1.

Android :: Align Image Buttons On A Curve Programatically?
Oct 6, 2010I have a series of buttons on a main menu. Instead of the standard side by side, or one on top of the other, I'd like them to be aligned around a semi-circle. Since I can't drag and drop the buttons to the place I'd like to in the designer, I was wondering the best way to do this? Can I do it in the XML, or would it be best to do it programatically?
View 1 Replies View RelatedAndroid :: Supporting Multiple Screen Sizes Using Image Buttons
Apr 13, 2010I've read the Android documentation:
http://developer.android.com/guide/practices/screens_support.html
but still have some questions. I'm trying to design a music application which basically has images of the instrument (ImageButton) that play a sound when clicked. However, I'm confused about how to have the ImageButtons scale to fit all the different screen sizes and how to position them.
Which layout is best used for needing to position ImageButtons in specific locations on the screen? (i.e. cymbals on a drum set) FrameLayout, RelativeLayout? If I only really care about medium and large screens, do I need to create different resources (images) for both as well as a different XML layout to position them? I'm trying to find the simplest way to do this without having to create a separate layout XML file for positioning/size and separate image resources for each screen.

Using Two Buttons In Activity
Mar 15, 2012I am new to android apps and I'm trying to make an interactive book for children. I want each activity to link to two other activities via buttons so that the child can make a choice on each page.
I can not figure out how to have two buttons on one activity that each lead to new activities. I can get the first button to work but not the second.It would look like:
Activity 1 leads to activity 2 or 3.
Activity 2 leads to activity 4 or 5, etc.
Android :: Pressing Home Or Back Buttons From Main Activity / Causes App To Stop Unexpectedly
Nov 13, 2010This is difficult for me to diagnose because the Log doesn't provide the offending code line that indicates what caused it.Running the app in the Emulator seems to work OK until I press Home or Back from the Main Activity. Using Back between the activities in the program seems to work OK, it only fails at the Main. I don't have the app finished yet so I haven't loaded it to a device yet.The Log says there was a null pointer exception so I would like to find why.The log points to the android routines (and I don't appear to have the source for those routines in the emulator-most but not all and these are refering to those I can't access). The log gives up at one point and says "11 more".It would be nice to see the remaining 11 in the hopes that one of them points to the line in my code that caused the offense.I'm looking for ideas on ways to find the error and hopefully cure it.

Aug 23, 2010I figured out how to pass a String value between activites thanks to this site, however I'm having trouble passing an image. What I'm trying to to is have a user click a button that opens the gallery and allows selecting of a picture. Then I have another button that opens another activity that displays an ImageView. I want to be able to have that ImageView's image be the chosen one from the previous activity.
Here is the class that has the button I'm clicking to open the gallery and retrieve the chosen image: code...
What I'm not sure about is in the OnActivityResult if I should pass the selectedImage or the chosenimage in the b.putExtra("bitmap", selectedimage); line. I tried both but I didn't see an image on the second activity. Also I wasn't sure in the PreviewScreen class if I'm setting the imageview correctly. Any help is appreciated. Thanks.
