Android :: Style Own Styleable With A Style - Custom View Class With Custom Attribute

Jul 8, 2009

I'm creating my own View class, and defining custom xml attributes with a attrs.xml. As long as I provide each attribute manually, there is no problem, but

code:...................

The android:text is properly set in my instance, but the borderDrawable is not. I guess this has something to do with namespaces, because inside the styles.xml, the name="mypack:borderDrawable" is not handled by the XML parser's namespace facility, because its inside an attribute value. So "mypack" is in no way connected to "http://some.weird.url.com/seems/not/to/ matter" and adding it via xmlns:mypack... to the stylefile would not help, I guess. In the same file, "android:text" is somehow recognized, even though "android" is AFAIK only a ns-defintion for [url], which is also not declared in that file.

So what is the proper way to set a custom attribute in a style?

Android :: Getting Style Attribute To Work

Jun 3, 2009

I finally decided to use styles and themes instead of tediously setting attributes for each individual view. I was able to get the style to work when I set it on android:textAppearance, but when I try to just set it right on the style attribute like below, it no longer applies.This is happening to me for Buttons as well as TextViews. What I want is to be able to have a few different styles for text views and buttons and then just set the style on each button or text view.The style will need to define textSize, textColor, background and maybe a few others.Since background and some other things are not textAppearance,I need to use the general style attribute.

Android :: 9-patches In - Selector - Drawable For Custom Button Style

Nov 28, 2009

I'm having a bit of a problem with a custom button style. I have the button states (9-patch drawables) set up in a <selector> drawable. The style I'm going for is a button that looks like it gets pushed down, i.e., you can see the front edge of the button until you press it. It works fine for the button itself, but the contents of the Button (or ImageButton) don't move when pressed, even though I have the 9-patch areas set up to move the content area for the depressed button states. It seems like it's keeping the same 9-patch areas no matter which image it's showing.

Here's an animated GIF to help make the problem a little clearer, since I'm awful at explaining things: http://www.crappytools.net/button_problem.gif The button moves when pressed, but the icon inside stays still. I played with the Draw 9-Patch utility, and it shows that the content area in the depressed image should be shifting downwards like intended.

Android :: Custom View Extending View-Class / Still Based On XML-Layout

Aug 17, 2010

I want to build my own custom view which should look like the Crysis-GUI.At first I designed a XML-based Layout and made it visible via the setContentView(int resid)-Method. Worked pretty well.But now I wan't to go a step further and draw in my Layout. So I created a new Class, let it extend View and overrode the onDraw()-Method. So far so good.But how can I still use my XML-Layout? I can't do setContentView anymore, so how could the same effect be achieved?

Android :: Accessing Style Items By Style ID

Nov 15, 2010

Any View have a constructor public View (Context context, AttributeSet attrs, int defStyle) which called when View declared with a style attribute So, if I have some class inherited from View class, I can access to declared attributes (like "android:layout_width" or "android:background") via AttributeSet attrs in a constructor. But when I move attributes to style I cannot see attributes and values exists in a style - I want to read items declared in style but I have only styleID in defStyle parameter. Is there some way to read style Items using styleID?

Spinner Style Can't Be Changed To Newer Style?

Jan 8, 2014

I've developed a fairly extensive application. The problem began when I started programming...my spinners are the solid gray rectangular style (unlike the newer style with the triangle in the lower right corner). When I started developing this app several months ago, I couldn't figure out why my spinners were different (after many hours) so I just ignored it. I'm at the point now of polishing my program and want the newer spinner style. So, I'm beating my head against the wall again. I went to my Android SDK Mananger in Eclipse and updated my Android SDK Tools, Platform-tools, and Build-tools. I have the lastest versions of all of these (22.3 and 19.0.1). When I create a new project, the newer spinner style appears. However, none of my older projects changed. They still have the same old gray, rectangular type spinners. I tried using a "android format" line command I found while Googling, but no luck with that either.I'm using ADT Bundle with build v22.2.1-833290 on a Mac OSX Mavericks.

Android :: Custom Animation Class Switches To Different View

Oct 4, 2010

I have a imageView, editText and textView within a LinearLayout. I would like to animate the EditText onTouch, to make it twice as taller and display a softkeyboard so that users can type into it. I cannot figure out if I should write some custom logic in applyTransformation of animation class which extends android.view.animation.Animation class OR go with a viewSwitcher which switches to a different view with bigger EditText. I would like to have a smoother transition if possible.

Android :: Any Way To Set Style For View At Runtime?

Sep 3, 2010

Is there a way to set a style for a View at runtime? I've seen this question a few times on the board here but no answers, so probably not:

<ImageView android:id="@+id/blah" style="@style/mystyle" />
// later... ImageView iv = (ImageView)findViewById(...);
iv.setStyle(R.style.myotherstyle);

Is it not possible to do something like this? We have to manually change everything in code instead?

I'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.

Android :: Create Custom Global Methods In My Application Class?

Aug 17, 2010

I currently have an app that has many activities and needs to have a way of maintaining state between these activities.

I use the Application class to do this, declaring my global variables and using getters and setters to interact with my activities.

I was hoping to place a few custom methods in there, so that when I want to do a common task like, for instance, display an error message, I can declare the method in my application class and call it from any activity that uses it

EscarApplication application = (EscarApplication) this.getApplication();

EscarApplication being the name of my application class above.

I have tried to include this method in my application class:

CODE:.....

In the hope that I can call this method from activity without having to redeclare it, but when I call it using something like below I get an null pointer exception:

Visit.this.application.showError("Update error", "An error has occurred while trying to communicate with the server");

Visit being the name of my current activity above.

Should this work, or can I only use getters and setters to change global vars in an Application Class.

EDIT Stack Trace:

CODE:...............

The dialog is declared as such in the application class:AlertDialog alertDialog;

Created in that same class:alertDialog = new AlertDialog.Builder(this).create();

And the method to call it in that class is as follows:

CODE:.............

And finally, it is called from an activity like so:

CODE:........................
