I understand how to create a custom Android control, and I believe I understand how to pull attributes for it from the Xml layout. I don't know, however, how to get any children elements from it. Here's a visual example of what I'm trying to accomplish: public class Menu extends LinearLayout. When my Menu is created, how do I get references to the two MenuItems. Code...

View 3 Replies View RelatedI have tried DroidDraw and the Eclipse layout editor and both seem very difficult to create anything other than very simple layouts. I find myself dropping back to the XML file to be able to manipulate it.
Has anyone found any good tools to design the actual screens? I am not looking for a mock-up tool... but an actual tool to create the XML layouts.
I am finding that my layouts tend to look great in one orientation but if I change the phone's orientation, things are a mess. For example on one screen I have 6 large buttons that look great in portrait orientation but if the user changes phone orientation, those buttons get cut off in portrait.
Do I need to code two layouts for every screen - one for portrait and one for landscape? That would be such a waste of time.
I am working on a project for which I have formulated a fairly complex layout but I have no earthly idea how I could implement such a thing. Attached is an image of what I'd like it to look like, can anyone think of a way to generate such layout?

How should one design the layout for these tablets?
would like to add a zoom control to the map. I also want to layout the position of the zoom Control instead of the default middle bottom position. I can do this by getZoomControl but it is deprecated.
Could anyone tell me how to do this with setBuildtInZoomControls?
I'm fairly new to the Gameboid and I just installed a Bios and everything works out great but the only problem I have is that the D-pad is in the top left hand corner and that makes my thumb conver half the screen... (HTC Hero Btw.) How could I get my layout to look something like this:

Some how so the D pad is more at the bottom and more visible, if the A and B were at the bottom it would be great too but thats not as big a deal.
I'm reading the android docs on custom component development and i'm a little confused. If you're creating an activity, you can add add a hierarchy of views via setContent. however, if you're creating a custom component, you have to handle everything in the draw() overload.if i want to build a custom component that relies on a view hierarchy, is the model simply to create a hierarchy internally and then in draw call myViewHierarchy.Draw() or something?
View 1 Replies View RelatedI've created a combo box control with a edittext and spinner. I'm trying to let the android:prompt attribute be passed onto the spinner, which means I need to catch it in the constructor which passes my the AttributeSet and set it on the spinner. I can't figure out how to get the value of the prompt.
I get back 0, which means it didn't find the attribute.I also did a ta.count() which returned 0. So I'm not getting anything back.My XML simply defines an android:prompt value.
I have a requirement to create a control similar to UITabBar in iPhone, which is to be present on every activity of my application. UITabBar essentially is a battery of buttons exhibiting a TAB like behavior: every button maps to an activity. I have two solutions for this: 1. In the layout XML for every activity, I insert a <LinearLayout><Button/><Button/><Button/></LinearLayout> element. And then have a common listener class that will handle the button clicks. So, every activity will have an instance of this listener. 2. To create a custom Widget extending LinearLayout class, put all the buttons as its static members and let it handle the button clicks. Include this custom control in every screen.

View 2 Replies View RelatedI am looking for a code-heavy way of controlling an android phone with scripts. For example, can you hook your android up to your PC and then control it virtually as if you were doing everything with your finger using scripts?
In my mind I imagine the code would look something like this (this is fake code):
1. var i = 30px;
2. Touch the screen at coordinates x, y;
3. Scroll to cords x, y minus i;
4. Touch the screen at cords x, y;
5. Swipe to cords x + 80, y;
6. Single click cords x, y;
7. if (cords x, y = rgb(0, 0-255,0) { //aka a shade of green
8. var count = count++ }
I have created a simple class named Panel which extends the SurfaceView class and does some drawing in the onDraw method. When I use it from the code it works fine. For example this works as expected:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new Panel(this)); ....
However when I try adding this component from an xml layout the program crashes:
XML file (main.xml):
<?xml version="1.0" encoding="utf-8"?> <org.anddev.Panel android:id="@+id/panel" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"/>
Code:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);....
Error msg: Sorry!
The application Test (process org.anddev) has stopped unexpectedly. Pleas try again.
I can not figure out why the same class works when created in one way and doesn't work when created in another.
Is it possible to create a button with a custom xml layout? Now I want to use this on a button. Anyone know how I can do this? I was thinking if I had Button.java file that extended Button. And then setView( R. layout. mylayout.xml); but that was to easy, and it clearly not working

View 4 Replies View RelatedI've created a custom view via .xml file, and I wanted to add it as a a contentView to an alert Dialog usinf a dialogBuilder:
CODE:.................
The problem is...I can't get my view from my custom layout... I only have an id (int)...
I tried Resource.getLayout(int) => it returns an xmlParser... not very usefull ...
finally the solution I comes up is so disgusting ( it worked but ... let's have a look)

How can I do that easily without using such a disgusting way... ?
I am trying to do is to embed a custom view in the default layout main.xml:
CODE:......
As you can see the class is called com.lam.customview.CustomDisplayView, with the id of custom_display_view1. now in the com.lam.customview.CustomDisplayView class, i want to use another layout called custom_display_view.xml because i don't want to programmatically create controls/widgets.
Custom_display_view.xml is just a button and an image, the content of which i want to change based on certain conditions:
CODE:..............
I tried to do:
1)
CODE:........
But got this error, "03-08 20:33:15.711: ERROR/onCreate(10879): Binary XML file line #8: Error inflating class java.lang.reflect.Constructor ".
2)

But got this error, "03-08 20:28:47.401: ERROR/CustomDisplayView(10806): Resource ID #0x7f050002 type #0x12 is not valid "
Also, if i do it this way, as someone has suggested, it's not clear to me how the custom_display_view.xml is associated with the custom view class.
I've created my own view by creating a subclass of the SurfaceView class.
However I can't figure out how to add it from the xml layout file.
My current main.xml looks like this:

What have I missed?
My view looks like this

And it works fine like this:

But nothing happens when trying to use it from the xml.
I have a dialog with a custom layout, and I try to close it when I press a button:
private void showAboutDialog() {
dialog = new Dialog(MainMenu.this);
dialog.setContentView(R.layout.about_dialog);
dialog.setCancelable(true);
dialog.setTitle(R.string.about_title);
dialog.show();
LayoutInflater inflater = (LayoutInflater) getApplicationContext().getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.about_dialog, (ViewGroup) findViewById(R.id.layout_root));
Button closeButton = (Button) layout.findViewById(R.id.about_close_button);
closeButton.setOnClickListener(new Button.OnClickListener() { public void onClick(View view) { dialog.dismiss();
} } );
}
But it doesn't work.
The button doesn't show in this layout(code below),image and textview are shown. I tried using relative layout but that doesn't help either.

I have a custom layout that draws a transparent rounded rectangle beneath its children. The problem is when I try to add it to my xml file, it doesn't show up. Also, when I try to add parameters to it (i.e. android:layout_width) the popup shows that none of them are available. The same thing happens to any child views I add. public class RoundRectLayout extends LinearLayout
{ private RectF shape;public RoundRectLayout(Context context)
{super(context);
LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
layoutInflater.inflate(R.layout.settings, this);
shape = new RectF();
}public RoundRectLayout(Context context, AttributeSet attrs)
{ super(context, attrs);
LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
layoutInflater.inflate(R.layout.settings, this);
shape = new RectF();
} @Override
protected void onSizeChanged(int w, int h, int oldw, int oldh)
{shape = new RectF(0, 0, w - 5, h - 5);
super.onSizeChanged(w, h, oldw, oldh);
}@Override
protected void dispatchDraw(Canvas canvas)
Paint temp = new Paint();
temp.setAlpha(125);

I am having trouble getting my layout to give me result I need, I already tried many options and it seems that I'm doing something wrong or completely missing something.
I have a listview with a custom row layout I can't seem to working although it shouldn't be complex. I need of the list row to insist of:
Icon -- title text (bigger and bold) with a short multi line text under the title -- ImageButton
My problem in most of my tests is the icon to the right usually doesn't appear, I guess my center group grows and takes all the space of the button. My last failed attempt was with a Relative Layout, didn't have too much luck with a Linear Layout either.
Here is the row XML:
CODE:.........................
I am running a sqlite query and binding the returned data to a ListAdapter.
I have used the following example
ListActivity | Android Developers
However, having defined a seperate layout for the rows I cannot change the typeface for textview text1 to a custom one from assets
Here is the row layout
CODE:................
Here is the code from the andriod tutorial
CODE:............
We'll define a custom screen layout here (the one shown above), but typically, you could just use the standard ListActivity layout. setContentView(R.layout.custom_list_activity_view) ;
Query for all people contacts using the Contacts.People convenience class. Put a managed wrapper around the retrieved cursor so we don't have to worry about requerying or closing it as the activity changes state.
CODE:................
Now create a new list adapter bound to the cursor. SimpleListAdapter is designed for binding to a Cursor.
CODE:................
Specify the row template to use (here, two columns bound to the two retrieved cursor rows). mCursor, // Pass in the cursor to bind tonew String[]{People.NAME, People.COMPANY}, // Array of cursor columns to bind to. new int[] {android.R.id.text1, android.R.id.text2}); // Parallel array of which template objects to bind to those columns.
CODE:................
I have created a custom list item layout just like in this article http://developer.android.com/resources/articles/layout-tricks-efficie....
Each list item has icon, title and summary.
I would like to declare an xml resource that would provide data for that list. Just like you use <string-array> to populate the list using ArrayAdapter<String>.
The simple ArrayAdapter<String> can be populated from:
CODE:..........
I need each <item> to have icon, title and summary. Somewhat similar to:
CODE:..........
I would use <menu> but menu doesn't have summary if I'm not mistaken.
I am trying to refer to a custom View in the helloWorld XML layout but I get the following exception:
Error inflating class acme.my.MyTextView.
However, I am able to instantiate the view and add it to the main content view manually. The custom View is built from it's own XML layout. How do I get this to work?
CODE:....................
I'm experimenting with the Android platform, and I'm beginning to love it, but right now I'm stuck, at this cursor/list adapter problem-thing.
The thing is, that I request a function, returning a data object, with several properties I'd like to map to different TextView's.
My list_item.xml
CODE:...........
So what I would like to do is: Map a property of an array of objects to several fields in the file.
