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

I would like to apply both an icon and text to a button. The button would have the icon centered in the button and text written at the bottom, centered. I could not get the text to center and be at the bottom using android:gravity.A side note, for a layout with 6 buttons is a Table Layout the best way to do it? There is 3 rows and 2 columns.Another side note, why does the button lose its rounded edges when I add background color?
View 1 Replies View RelatedI 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.
Currently, I am creating a custom View class (DrawView) that inherits the View class and adding to my activity programatically by using RelativeLayout and LaoutParams etc. But is there an easier way to do this by adding my DrawView to the layout XML file?
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)
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.
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:
CODE:............
What have I missed?
My view looks like this
CODE:..............
And it works fine like this:
CODE:..................
But nothing happens when trying to use it from the xml.
each child is horz linear layout w/ 3 children: image view, linear layout container and then an image button
if the image button is GONE - then i get click notifications when someone clicks on the list entry. if the image button is VISIBLE (even if i don't intercept onclick) - i don't get the list click event notification.
i am trying to display a linear layout , say at setpadding (10,10,0,0); now i need to put some buttons at particular xy position in layout.button position doesn't seem to work in that way. can anybody suggest how can i set button position in layout?

<LinearLayout android:id="@+id/header" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:gravity="center_vertical" <ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="top" android:src="@drawable/img1" /> <TextView android:id="@+id/atitle" android:singleLine="true" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout>
I need to add a button to the above layout problematically which is right justified? I need to do that in code instead of layout xml file (this is because i can't modify that layout xml file). Here is what I am doing: LinearLayout header = (LinearLayout) findViewById(R.id.header); Button buyButton = new Button(this); buyButton.setText(R.string.buy_ringtone); buyButton.setLayoutParams(new LayoutParams( ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); header.addView(buyButton);
But the button does not appear. Can you please tell me how can i achieve that?
I'm expanding on the hello world application. I've created a button on the main.xml to bring up a new form, screen2.xml, with a second button. I'd like this this button to toast a message. However, as soon as I try add the code to define the OnClickListener, I get a force close message.Does this mean one Activity can only access one screen/layout?

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.

View 2 Replies View RelatedIm 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.
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...

My LinearLayout has a button and a WebView. The problem is that only the first one in layout can be clicked, the other is not. If I put WebView first into the layout, the button is not clickable. If put button in the layout first, then WebView is not clickable.Is there a setting to enable this?

I am very new to this so please use detailed instructions.I have not experimented with drawable images yet so I want to clarify before I continue.If I want to above the text (ie the text is not on the image) how do I go about doing this? I also want the text to be centered in below and (working without the drawable) there is a gravity command for center-horizontal and bottom. This made an error. Appreciate the help and remember I am a beginner to Eclipse and Java.

View 1 Replies View RelatedI am working on a fairly basic screen layout for my first Android application and running into some issues. My goal is to have a TextView in the top left and top right corner, a large "hello world" TextView in the exact middle of the screen, and then a button at the bottom of the screen.My issue is, to center the "hello world" TextView vertically, I need to set the layout_height="fill_parent".However, this causes the middle TextView to cover and hide the button at the bottom of the screen. Is there a better way to do this than what I am currently trying?
