Android :: Use Values Declared In XML On My Custom Layout?

Aug 13, 2010

Im creating a custom layout and I want to use the text declared in the layout.xml file in my layout.

Like when I create a TextView in XML and set android:text=@string/text1 when I run the app text view automatically loads the text from android:text. So how can I access attributes declared in the layout XML file in my custom component.

Android :: Using Resource Values As Layout Attributes - Config.xml

Mar 28, 2010

Looking in the android sdk folders, I've found a file called values/config.xml. This seems to be somewhere that you can define values for later use in layouts and animations.

Given the config.xml:

<resources>
<string name="config_somePadding">50dip</string>
</resources>

How would I reference this to use as the layout_height in a layout xml file?

@string/config_somePadding is actually the only one I've found that doesn't throw an error in Eclipse (even though there isn't a config_somePadding in values/strings.xml), but it appears to just put an empty string.

In the sdk, they use an integer for animation duration. They reference it like this: android:duration="@android:integer/config_longAnimTime". Is there a way to use values that aren't integers in the layout_height attribute?

Android :: Changing Values Inside Layout Included With Include

Oct 28, 2010

I have in many of my screens that re mostly constructed of LinearLayouts a FrameLayout that should take up the bottom leftovers of the screen (using layout_height="0dp" layout_weight="1") inside it there's a FrameLayout with gradients background and in it's middle with some padding lies a button with some text, naturally i need the text and onClicked properties to me different from screen to screen. I considered using <include > tag for the above compound in my layouts, but as far as i can see i can't really change (at least not in xml) the button text and callback, is that really so?

Android :: Custom Contacts Field With A Set List Of Values And Contacts Lookup Performance

May 28, 2010

I'm pretty sure it's not viable to do what I'd like to based on some initial research, but I figured it couldn't hurt to ask the community of experts here in case someone knows a way.

I'd like to create a custom field for contacts that the user is able to edit from the main Contacts app; however, the user should only be allowed to select from a list of four specific values. A short list of string values would be ideal, but an int with a min/max range would suffice.

I'm interested in knowing if it's possible either way, but also wondering if it make sense to go this route performance wise. More specifically, would it be better to look up a contact (based on a phone number) each time a call or SMS message is received or better to store my own set of data (consisting of name, numbers, and the custom field) and just syncing contact info in a thread every so often? Or syncing contacts the first time the app is run and then registering for changes using ContentObserver?

I've spent quite a bit of time on this and am inclined to file a bug report at this point. I can see a reference to the allegedly missing class in the classes.dex file inside the APK and the code works properly in the emulator. I haven't been able to find anything like this, so if there is, an RTFM pointer will be humbly accepted.

Android :: XML Layout Of Custom Component

Jul 9, 2010

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.

Android :: Custom View With Layout?

Mar 9, 2010

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)
CODE:..........

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.

Android :: Writing Custom Linear Layout

Jul 26, 2010

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);
canvas.drawRoundRect(shape, 10f, 10f, temp);

Android :: Listview Custom Row Layout - Tried Many Combinations

Jun 13, 2010

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:

Android :: Custom Typface In Listview Row Layout

Aug 6, 2010

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.

I have defined custom views in the various layout .xml files. However, all the layouts are using the Linear Layout - put the content would vary.

I would like to create my own widget tag something like <com.mypackage.MyLinearLayout />, I would like to pass the layout as a param to the <com.mypackage.MyLinearLayout layout="@layout/simple.xml" />

How to define new attributes to the custom widgets ? Simply defining a getter/setter method would work or is there any other references.
