Android :: How To Add EditText Field To An AppWidget - RemoteViews
May 14, 2009
I am trying to add a "EditText" Field to an AppWidget. I took the AppWidget example from here: http://developer.android.com/guide/samples/ApiDemos/src/com/example/andr oid/apis/appwidget/index.html and modified it by replacing the TextView with a EditText. It doesnt work... Compiles and runs but the Widget sais "Problem loading Widget" when it shows up.
Maybe an example? Is the default Google Search Widget open source? Can someone give ma a link to the source?

I suspect the answer is no, but it only seems possible at the moment to update an AppWidget via a RemoteViews object which is inflated from a static XML file.
Is there any way to build a RemoteViews object on the fly, or edit the layout of one that is already there?
The requirement is that I don't know until runtime exactly how many ImageViews I want to display in my AppWidget.
Currently I am setting all the ImageViews I may need in the layout XML file as invisible and then just making the ones I want visible, but am I then limited to what I have in the XML file to start with. It would be far more convenient to be able to just add the ones I need on the fly, and set their properties when updating.
Anyone know if there is a way to do that?

I have an EditText field and a button. My aim is to let user enter text info to the EditText or click the button to launch a dialog to select some checkbox and radio button which it will perform some computation and return a value to display at the EditText field.
I can't seems to get the value to display at the EditText field after the dialog dismiss. I did try a toast to display the value and it is ok. I *think* the view was not refresh to display the text in the EditText field.

Why is the textSize attribute ignored in EditText-fields? How can I make the text in those fields smaller, so that ALL cells have the same font size? Why does Android not honor that attribute, even if explicitly set?

I have a setup view where the user can enter their name and email and click done when they are finished which navigates them to another activity1. When they are in activity1, and they hit the soft back button on the phone, it takes them screen where they entered their name and email. However, the name and email EditText fields are blank. In the view where the name and email are entered I looked to see if onStart, onCreate, OnPause, onResume,... where being called after the back button was hit, but they are not. Do you know how I can make it so that the EditText fields have the information that was previously entered.

I'm in the process of figuring out how to develop for android...and I'm trying to add an EditText field but I get and error. Looking at the graphical layout, the screen fades out. Is there a reason this would happen.
I am also getting an error that says "Failed to load properties file for android project".

If I have an EditText component on my screen that I have specified inputType="decimal" for (i.e. a numeric/decimal field), what is the best way to convert it to an decimal value in the application code?
Google recommends avoiding floats, and avoiding creating objects unnecessarily (and I assume any auto-unboxing code is bad too), so I take these as my constraints. I realize a small application probably doesn't need to worry too much, but I haven't been able to find a 'best-practice' solution to this.
The most common solution appears to be this:
double value = Double.parseDouble(txtInput);

I have a simple EditText field in one of my Activities. If I set the field to disabled, it greys out and I cannot enter text with the hardware keyboard, however when I touch the field the virtual keyboard appears and that still lets me enter text. Is this a bug? Any workarounds for making sure this can't happen?

I have a widget, working happily on 2.2, which includes this line:
CODE:............
When I run it on 1.5, I get this:
CODE:...........
Unsuprisingly, the widget doesn't appear. But I'm not quite sure what is not supported here. RemoteViews.setBoolean is documented as supported since API level 3, and ImageButton.setEnabled has been there forever.
Is there some separate question about which functions setEnabled is prepared to do business with ? Or, if not, what could possibly be wrong here ?

I'm writing a widget. Currently, I'm have a simple ImageView, and calling RemoteViews.setImageViewBitmap(). I'm using a service to do the updates.
I thought it might be a good idea to reuse an existing RemoteViews instance, so I'm only querying it the first time around, and subsequently simply call setImageViewBitmap() with the new image.
This works well initially, but after some time I first start getting "!!! FAILED BINDER TRANSACTION !!!" errors, and later, an OutOfMemory exception.
Simply creating a new RemoveViews instance every time works flawlessy on the other hand. I'm just curios why that would be, any ideas?

Adding an image on EditText works fine. However, copying an image is another problem. When I insert an image on EditText by using ImageSpan it shows correctly, but I copy inserted image, EditText shows me only 'obj'.

I want an EditText to look like TextView but still behave like EditText. I've tried applying TextView style to my EditText in my layout.xml file, like this:
CODE:............
But I get an error within xml editor: "Error: No resource found that matches the given name (at 'style' with value '@android:style/ Widget_TextView')." It is strange because @android:style/ Widget_TextView definitively exists - I double checked it in code via android.R.style.Widget_TextView. Another strange thing is that I don't get android:style offered in the xml editor while typing? There is android:id, android:text and everything else.. but not android:style?
I consider the hard way (making EditText look like TextView) to be: extending EditText and overriding it's onDraw method.

Our app (WordPress for Android) uses a ScrollView for the new blog post view. The issue is that if a user writes a lengthy blog post in the EditText, they are unable to scroll inside of the EditText because the ScrollView seems to be taking over the scrolling action, even when you are in the EditText.
Here's the layout XML (the EditText in question is @id/content):

Every time I put a TextView before an EditText element in a LinearLayout, the EditText does not show. When I don't, it does.
I've narrowed the problem down to the TextView's layout_width attribute. If I give it "wrap_content", it works, but doesn't "block" down, and it appears on the same line as the EditText.

I am trying to debug a problem where my widget becomes invalid and a new one fills in.This only happens once at the beginning of time and then it remains the second widget forever.So, I want to put code in to narrow down the point in time when it happens.Then I would get a list of all the enabled IDs and see if I am in the list. I cannot find a method, member, attribute, etc. that would give me my id?

I am attempting to query a database and update information in the appwidget screen based on changes to the database done while in an activity so that when the user exits, the changes are reflected in the widget on the screen.The appwidget is being updated with a broadcast from OnPause() and OnStop() in my primary Activity.Relevant pieces of the code are below.The Toast shows me that the data is correctly being pulled when OnUpdate() is called.But the widget refused to change

Just wonder what limitations there are for UI elements in AppWidgets? I tried a ListView and was met with an error. I saw the other post that EditText isn't available.Just wondering if there was a full list somewhere?

I have a strange problem, on a few devices. I have developed an AppWidget, and it uses a database to store the configuration for each instance of the widget. The widget id is the key in the database.Everything works on most devices, but I got a bug report a couple of days ago. A user said that the widget never worked after reboot. The user who was very helpful sent me a log from his phone, and I could then see that the widget got a new id each time he did a reboot.
