Android :: Dynamically Change Widget Background

Jul 4, 2009

I am working a widget... I'd like to change my widget background image dynamically, is it possible? I tried theme & style, it doesn't want to work. It doesn't show any background image (see code sample below). I tried RemoteViews.setImageViewResource on an ImageView filling the widget, but i doesn't strech my 9patch image correctly (and it doesn't seems to change background, it add another image). Is there a solution? Additionnal question : is it possible to use an external (sdcard) 9patch image as background? if yes: how?

Android :: Change Background Color Of Widget When Tapped / Scrolled To?

Oct 21, 2009

I made a custom widget (which is just a composite like):

<LinearLayout> <TextView> </LinearLayout>

this widget is focusable and reacts to touches. I'd like it to change its background color to the default system highlight color when the user scrolls to it, and have it blink when the user taps it (just like an element of a ListView does).

I can add an OnFocusChangeListener for when the user scrolls to it, and in the handler do the changing of the background color.

How would I add the 'blinking' behavior though when the user just taps it with a finger? I did something like this as a test code...

this is just a guess. Is there a correct way of implementing this behavior?

Android :: Set Image / Background Source Dynamically

Oct 11, 2010

Is there any possibility to set background image dynamically? I try to explain what I mean.

String picVariable = getPictureFromServer();
ImageView image = (ImageView)v.findViewById(R.id.dynamic_image);
// I know, that doesn't work, but that's the way I looking for
image.setBackgroundResource(picVariable);

I also read this article. It would suggested in one answer, to use java reflection to get a field of the R class by name. But I've never used reflextion before.

Android :: Setup Background Of A TextView Dynamically From Xml File?

Oct 10, 2010

I have an XMl file like below which I will use to set background for Textview:

row.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"

android:shape="rectangle">

The above Xml I will set as background for TextView in main.xml as below:

main.xml

<TextView
android:id="@+id/rowtext3"
android:text="Availablity"
android:layout_height="25px"
android:layout_width="60px"
android:textSize="10px"
android:textStyle="bold"
android:textColor="@color/black"
android:gravity="center"
android:background="@drawable/row"/>

But I want this to do from code rather than Xml.I have done everything that I have done in Xml like font,width,Height,font dynamically through code , but not able to set Background that I mentioned in Xml file . How can we set content of Xml file as background to textview similar to how we set background as XML in main.xml.

In the code I have done like this:
t1=new TextView(this);
t1.setText(ed1.getText());
t1.setHeight(25);
t1.setWidth(60);
t1.setTextSize(10);
But I didn't find how to set background i.e. how to set XML content as background?

Android :: Dynamically Adding A View To Activity Layout

Aug 18, 2010

I have a custom view (an extension of a TextView) that I want to dynamically add to my Layout (don't want to include it in the main.xml file).

The book says to fetch the RelativeLayout using findViewById() in my java code then create a new instance of my custom view, then use addView on the RelativeLayout to add the new view.

I'm not getting any errors, but when I click my button to add the new view, nothing is happening (view isn't being added). Do I need to set additional properties on my custom view (layout width, layout height for example) in order for it to be shown?

Adding code

Android :: Displaying XML-based Layout / Adding Text Dynamically

Sep 12, 2009

I have a LinearLayout defined in XML that I want to use repeatedly to display elements of a list. The XML-layout looks like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/background"
android:paddingBottom="5px">

<TextView
android:id="@+id/destination"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="22dp"
android:text="@string/test_destination"
android:paddingLeft="5px"/>

<TextView
android:id="@+id/date"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="15dp"
android:text="@string/test_date"
android:paddingLeft="5px"/>

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/info"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="5px"
android:paddingTop="10px" >

I gather information about certain events from a webpage, and then I want to display all events in a list using the above layout for each event. My current approach is to have a LinearLayout as parent and then adding each event as a row.

Problem number one is to add the layout to each event (the number of events is varying). I.e., I want to dynamically inflate this layout for each event. I also don't want the text to be hard coded into the layout (as above) but added at runtime. I don't know how to do this. I have tried something like the following without any success.

LinearLayout eventView = (LinearLayout) findViewById(R.layout.event);
parentView.addView(eventView);


Problem number two is then to add these layouts to the parent view group and display it on the screen. When I try to do this using parent.addView(child), the program crashes at runtime and I can't figure out why.

It's kind of hard to describe the specific problem, since I'm new to GUI-programming on Android and I'm sort of programming by trial and error right now. Anyway, if you are able to help me with some of the problems it would be greatly appreciated. Linus

EDIT:
The problem now is adding text dynamically to the TextViews. I try this:

TextView dest = (TextView) findViewById(R.id.destination);dest.setText("myText");

only to discover that dest is null. Any ideas why and how to fix this?

EDIT 2:
I have narrowed the problem even more, but I really don't understand its nature. This is the trouble-method: Code...
it somehow works (even though the events are displayed in reverse order). Anyone knows what's going on here?
