Android :: AppWidget On Homescreen : Focus ImageView / TextView With Trackball?
Feb 6, 2010
I coded an AppWidget the user can add to his homescreen. There are a bunch of images (ImageView) in it that perform different actions like starting Activities on click (realised with PendingIntents). To make it easier to navigate through the AppWidget I'd like to use the trackball (as it works with the SearchWidget or FacebookWidget) but I just can't make it work. Here's my layout code for the AppWidget...
So I want to be able to navigate through a bunch of these "Spots" that are all relativeLayouts. How can I make that work out? I'd be really happy about every hint or idea!

I'm trying to create an appwidget with a customizable background. I use a NinePatchDrawable and I would like to change it's color (using the setColorFilter method). This is no problem in an Activity, but it does dot seem possible with the RemoteView object used for appwidgets.Is there some way to get an ImageView in an appwidget to be updated with a new Drawable, not a Bitmap?Or if not, perhaps it's possible to get the actual size of the appwidget and convert / save the colored NinePatchDrawable to a Bitmap and then update the ImageView with that?I already searched quite a bit for a solution, but haven't found anything so far. I hope it's not impossible.

I have different elements in my layout: Buttons, RadioButtons, EditText, a ListView and I have made a RelativeLayout that is clickable and starts a new intent. Everything works ok except that I can't select that element with the trackball. Is there any way to achieve this?

I have a listview, and wanted to make some list items to be non-focusable. i.e On pressing the down-arrow key, some items in the middle of the list gets skipped.
I tried the following method. 1. created separate ArrayAdapter class. 2. override getView method. 3. In getView, I called setSelected(false) and also tried setFocusable(false) for some items, but its not working.

I have a TextView with android:maxLength set to 3 and another with android:maxLength set to 7.
I want focus to automatically move to the second TextView once the 3 chars of the first TextView are filled up. Is this possible without inheriting TextView and writing a custom implementation ?

There are an EditText and a TextView in my Activity. I want to set focus on the TextView when the Activity starts. I used the following code:
TextView myTextView = (TextView) findViewById(R.id.my_text_vew);
myTextView.setFocusable(true);
myTextView.setOnClickListener(this);
myTextView.requestFocus();
But the code doesn't work. The EditText always receives focus when the activity starts.

When changing screen orientation while running an Activity that has both a normal layout and a layout-land file defined (both of which contain a TextView), then that view loses its focus after being restored and a warning is issued on the log:
"Previously focused view reported id X during save, but can't be found during restore."
Is this a bug? I looked at the mID field of that view, and it's identical for both the portrait and the landscape layout.

I started a test project just to get this down. No changes to main.xml. I want to create a widget-sized ImageView (80x100) that contains a Bitmap converted from a TextView. Yes, that sounds very roundabout but this is just for testing; in the end I want the ImageView to have a background image and multiple TextViews. I'm not sure exactly what I'm doing wrong, but nothing is being pushed to the screen.
Is it a problem with declaring the TextView/ImageView and passing it "this" in the constructor? Is it a problem with my layoutParams? Here is the code:
package com.doaf.testproject;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView; Code...
I'm relatively new to Android, and pretty lost with this one.

In my application I have a title(TextView) and an Image. The image is grabbed from the web and most of the images are different sizes. Some of these images are to tall and overlap on top of my textview, covering it up. Is there anyway to prevent this? code...

I'm having a problem with incorporating an imageview with a textview into a list view.
Activity code:
Code:
ListView menuList = (ListView) findViewById(R.id.ListView_Menu);
String[] menuitems = {getResources().getString(R.string.playgamebtn),[code]....
displaying the imageview and the textview isn't the problem it is clicking on it. When clicking on the textview, there is an error with the ArrayAdapter.

I loved the camera on the Eris and the Incredible, not only did they have a whole lot more of a crisp high-res detail, the auto-focus absolutely rocked. With my droid x, I can be getting a little artsy and focus on an object with the crosshair but it'll take me 20 tries to get it to lock on, its insane, I know I'm not getting too close to my subject because it will definitely eventually focus on that object if I try over and over and over again. It's not just close ups that I find myself and my buddy with this issue either. macro shooting mode does not help. My buddie's droid X has the same exact behaviors. Eris and incredible just LOCKED ON first try with even very low contrast / detail subjects, on top of that, have a ton better camera GUI when it comes to "click to focus". I know this thing ain't no SLR but, blows me away of how terrible the camera performance is vs. the HTC android based devices. Ihink motorola will fix this? I know this thing ain't no SLR but it just blows me away how the HTC android devices camera performance (except for video) blows the Droid X away.

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.

I am trying to update an AppWidget manually when a user setting changes on the device.I can tell that my AppWidget onUpdate method is being called as a result since I log some debug strings to logcat in the code. However the AppWidget itself doesn't change on the screen.Here comes the interesting part: if I rotate my device and force a refresh of the home screen (from PORTRAIT to LANDSCAPE or vice-versa) then finally my AppWidget gets updated. However rotating the device does not trigger the onUpdate method to be called, so the AppWidget must be using the RemoteViews provided in the earlier update. Can somebody explain me what to do to force the home screen redraw of my AppWidget when it processes an update?

I wrote a widget that has been working fine for most folks. However, I started getting bug reports about how the widget would be blank on reboot (not receive an update?), and it seemed that the Sprint Hero continually came up. I thought I was crazy but I'm finding that other people are having the same problems:Searching Google for "sprint hero appwidget problems" yields:"Added warning about the problem on the Sprint Hero device: On the Sprint Hero (HTC ROM v1.29.xxx) the AppWidget API is broken in such a way that it won't."I e-mailed the author in hopes of getting an answer, but I haven't received any response. Does anybody with a Sprint Hero know what the problem is?

Using Appwidgets, If we use TextView in layout provider xml then, we are able to set the text in Provider.java using remoteViews.setTextViewText() method.
Similarly, if I use AnalogClock as AppWidget in xml then, is there any method available to change the android:dial value using RemoteViews or AnalogClock api's in Provider.java ?
For Ex- I need to load two dial png's based on AM or PM.

I'm developing a Android AppWidget for my application. For updating my appwidget I need to download data from network. But when I try to do that in onUpdate method, my appWidget is killed by Android system. I learnt that time consuming operations can't be done in receivers so I launched a service from onUpdate method and launched a thread from that. But still the problem persists.
Can anyone please let me know how to do network operations in Appwidget?
