Android :: Using ScrollView Inside Layout Xml File For A Widget - Got Error

Nov 22, 2010

I'm able to successfully use a ScrollView inside the layout xml file for an application. However, when I tried using a ScrollView inside the layout xml file for a widget, I get a "Problem Loading Widget" error as soon as I drop the widget in the emulator. If I comment out the ScrollView, then the widget shows up in the emulator. I've pasted my layout xml file below. Any thoughts on how to get past this error would be much appreciated.



android:text="@string/button_ok" />





android:text="@string/button_ok" />

Android :: ScrollView .scrollTo Not Working - Saving ScrollView Position On Rotation

Jul 16, 2010

I must be overlooking something real simple here, but i think i'm trying to do something fairly basic.. Simply retain the scrollbar position of a ScrollView on orientation change...

Here is the code for my onSaveInstanceState and onRestoreInstanceState.. sView is the container for the ScrollView layout. Within my scrollview is a linearlayout with a lot of textviews.


If I set a Toast with the values of sViewX and sViewY on the Restore, the values are kept and correct.

I just tried to do a sView.scrollTo(0,150); in my onCreate.. just to see if that would open the activity at 150px down, and it didn't. I think my issue has to do with the .scrollTo method.

Android :: Create A ListView That's Not In A ScrollView - Or Has The ScrollView Disabled

Mar 10, 2010

I want some of the goodies in a ListView, like being able to use a ListAdapter, and item selection, etc, but I don't want the ScrollView portion of it. I want to implement that part myself, in a different way (why or how I do this isn't really the point of this question, so please don't ask "why"). Is there a way to have a ListView that's not in a ScrollView or has the scrolling disabled?

Android :: Custom Xml Attributes For PreferenceScreen

Sep 26, 2010

I use custom xml attributes for preferences. The preferences are inflated from xml.I managed to create and read custom xml attributes for EditTextPreference, ListPreference and CheckBoxPreference by creating custom classes which inherit from the respective preference class.My problem is that I can't do this for the PreferenceScreen class, as it is a final class. So my question is: Is there any way I can read the custom attributes of a PreferenceScreen?

Android :: Attributes Represented By Expresions

Nov 26, 2009

Is it possible to define an attribute value of a height attribute, for example, relative to its parent's height. For instance, I want the linear_layout's height to be 2/3 of its FrameLayout parent. I have a FrameLayout with two linear_layouts. The first linear_layout fills the entire FrameLayout and the second linear_layout overlaps the first but only 2 / 3 of its height.

Android :: Set TextView Attributes Programmatically?

Sep 12, 2010

I am desperately trying to set TextView attributes of cells within a table programmatically but can't get this to work! Whenever I set layout properties, the field will simply not appear (but not give any error or exception). I boilded this down to this simple example:


This will show three fields, but when you uncomment the five commented line, then NOTHING will appear. Why is that so? Why does setting layout parameters cause my TextView's to not appear? I'm stuck! What am I missing?

Here's the manifest, if some kind soul quickly wants to try this out:

Android :: Weight Sum - Layout Attributes Not Working

Nov 26, 2009

I have a simple horizontal linear_layout with bunch of image views in it. the trick is that the views have different widths, relative to the size of their parent (the linear layout). I set the layout's weightSum to a 100 and the layout_weight to let's say 10 of one view and 15 of the other, on so on. And it did not work. I also tired using float values setting the weightSum to 1.0 and the layout_weight of the image views to 0.2 and 0.3 and so on. But it didn't work either. I did search this group for any references to the weightSum but found nothing. Any ideas how to handle it?

Android :: Attributes For Multiple Resources In Attrs.xml

Apr 17, 2009

I'm introducing multiple custom widgets for my application, extending View. These widgets (LineGraph and DotMatrix) include various attributes that can be set via the layout-xml. How can I have multiple widgets using attributes with the same name. For instance, 2 attributes both having color as an attribute that can be set via the layout XML?

main.xml snippet:


When I want to add the info for my LineGraph in attrs.xml, Eclipse starts to whine: "ERROR Attribute "color" has already been defined" XML:


Is it not possible to have a DotMatix resource with a color attribute, and a LineGraph resource with a color attribute?

Android :: Custom Widget - Attributes In The Layout Xml Files

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.

Android :: Setting Layout Attributes Based On OS Version?

Sep 14, 2010

Is there a way to specify a background in a layout based on OS version?:


I'm running into a problem where using a 9 png drawable for the background causes a stack overflow exception on a listview item (stack trace shows its related to a child TextView -> drawText()). The layout is simple:

<LinearLayout><ImageView /><TextView /></LinearLayout>

and the background works fine on 1.6 and above. It's just 1.5 that's having the issue. If I set the background to be a color, it works fine.

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:

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

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?

I'm looking for a way to implement a minimum value in my SeekBar and also have the option to increment decimal numbers. For example, currently my SeekBar's minimum is set to 0, but I need it to start at the value 0.2. Also, I would like to have the functionality to be able to have the user select a number from 0.2 to 10.0 at a .1 precision so they can choose the numbers 5.6 or 7.1.

Android :: Relative Layout XML Attributes Have No Obvious Programmatic Equivalent

Jun 16, 2009

If a RelativeLayout must be generated at run time, what are the equivalent API calls for the attributes set in the XML Layout editor? Take for example this very simple RelativeLayout that places the second ImageView to the right of the first ImageView:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android=" android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="horizontal" android:background="@drawable/ bg_sunrise"
android:layout_gravity="center" android:gravity="center">
<ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/icon"></ ImageView>
<ImageView android:id="@+id/ImageView02" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toRightOf="@id/ ImageView01" android:src="@drawable/icon"></ImageView> </RelativeLayout>

Of the many, variations I tried, I had the most hope for this one, but it didn't work either:

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
RelativeLayout layout = new RelativeLayout(this);
layout.setLayoutParams( new ViewGroup.LayoutParams (
LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT ) );
ImageView imageView1 = new ImageView(this);
// set the ImageView bounds to match the Drawable's dimensions
RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams (LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params1.addRule(RelativeLayout.ALIGN_PARENT_TOP); layout.addView(imageView1, params1);
ImageView imageView2 = new ImageView(this); imageView2.setImageResource(R.drawable.icon);
imageView2.setAdjustViewBounds(true); // set the ImageView bounds to match the Drawable's dimensions
RelativeLayout.LayoutParams params2 = new RelativeLayout.LayoutParams
(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params2.addRule(RelativeLayout.RIGHT_OF, imageView1.getId());
layout.addView(imageView2, params2); this.setContentView(layout); }

Can anyone offer the Java equivalent to the above XML? Can anyone explain why there is no attribute, getter/setter, or method for accessing the properties that can be set in XML? What is the most elegant solution for dynamically creating Layouts, Views, and other Resources on the Android platform when there is no Java programmatic equivalent?

Android :: How To Automatically Resize An EditText Widget With Some Attributes In TableLayout

Apr 28, 2010

Method addTextField() specifies the attributes for the EditText widget:


So far, so good. But my problem occurs as soon as the available space for the chars is depleted. The EditText does not resize itself but switches to a single line EditText.

I am desperatly looking for a way in which the EditText resizes itself in its height dynamically, being dependant on the inserted text length.

Getting Build Errors On Theme Attributes

Aug 20, 2013

I want to change the values of a couple attributes in Theme.

I've looked at the file /platforms/android-15/data/res/themes.xml and found these attributes in the definition of Theme --

<item name="androidanelMenuIsCompact">false</item>
<item name="androidanelMenuListWidth">296dip</item>


when I build, the item lines get the errors --

No resource found that matches the given name: attr 'androidanelMenuIsCompact'.
No resource found that matches the given name: attr 'androidanelMenuListWidth'.

We know these are valid attributes, since they are in the theme definition, and they are also in the file attrs.xml, in the same directory as themes.xml.
